Nikon launches the D7100 with its latest DSLR. It is equipped with a CMOS image sensor, which dissolves and the 24.1 megapixel APS-C size equivalent (as described in the Nikon DX-format system). The special feature of the camera is that it operates without optical low-pass filter - which according to the manufacturer to increase the sharpness of detail. The ISO sensitivity ranges from ISO 100 (expandable to 25,600) to the 6400th.

Nikon D7100 key features

24.1MP DX format CMOS sensor, with no OLPF
EXPEED 3 processing

1050mAh nikon d5100 battery

The critical thing here is that despite the fact that the D7100 is Nikon's third DX-format 24MP DSLR, its sensor is new, and unique in Nikon's stable. In a first for Nikon, the D7100's sensor lacks an optical low-pass filter (OLPF). The D800E, Nikon's highest-resolution DSLR has the effect of its OLPF 'cancelled out', but the D7100, like the Pentax K-5 IIs, omits it altogether. The result should be higher resolution than is possible from the conventional 24MP sensors in the D5200 and nikon d3100 battery, and Nikon clearly feels comfortable with the associated higher risk of moiré in fine patterns - one of the few black marks against the 36MP D800E when we tested it last year.

Nikon D7100 with high-end autofocus
The AF system of the D7100 is similar to the professional DSLR nikon d3000 battery and works with 51 focus points, 15 cross-type sensors in the center, and a metering sensor with 2016 pixels. The burst speed of the Nikon D7100 is at 6 frames per second. The optical viewfinder provides virtually one hundred percent frame coverage and 0.94 magnification. This is an extremely sharp and large display with 3.1-inch diagonal and 1.229 million pixels. The body of the camera is sealed against moisture and dust.

New a switchable 1.3-fold-field option is added to the normal DX format. This 1.3-fold telephoto effect provides an effective resolution of 15.4 megapixels and allows in full HD video mode with nikon en el14 battery, frame rates of up to 60i or 50i, in the standard format (APS-C or DX) are only 30p, 25p or 24p possible.

The Nikon D7100 is expected to come from mid-March 2013 in the trade, the body will cost around 1,180 euros. The kit with the AF-S DX Nikkor 18-105 mm 1:3.5-5.6 G ED VR is the price will be around 1,400 euros. The D7100 is the Nikon D7000 does not replace loud, this will continue to be available.

The U.S. computer maker Hewlett-Packard (HP) is officially back in the mobile business. Having recently been rumors began circulating, the company now has in the mobile World Congress (MWC) 2013 presents the Android tablet HP Pavilion G6 battery Slate 7th When the device is a reasonably priced entry-level model without any special equipment to do.

As the name Slate 7 leaves, the tablet has a 7-inch display which offers a resolution of 1,024 x 600 pixels. Android comes with 4.1 alias 'Jelly Bean' is used by HP and is apparently only slightly modified.

Inside the HP pavilion dv8 battery device installed a dual-core processor with a clock speed of 1.6 gigahertz, which is based on the ARM Cortex A9 architecture. From which comes the SoC chip producers, reveals the U.S. company does not. In advance of the product launch HP's tablet was at least not yet associated with the much more powerful Tegra chip from Nvidia-4-connected. Perhaps the only points but also points out that the group has more tablets in the works.

The processor is assisted by 1 gigabyte of RAM and 8 GB of flash memory. The latter can be expanded via micro SD card slot. Information on battery capacity is not available.

To wireless standards supported the Compaq presario cq62 battery Slate 7 WLAN b / g / n and Bluetooth 2.1, the rear seats for a 3-megapixel main camera on the front with a 0.3 megapixel sensor is for video chatting. With GPS or NFC support can not come up, the device offers, but for the integration of Beats Audio technology, which should make for a better sound experience.

HP ev088aa plans to offer the Slate 7 from April in the U.S.. The suggested retail price is U.S. $ 169.99 there. On the plans, when and at what price the Android tablet will be available in this country, is not the ultimate producer.

The display of the Toshiba pa3591u-1brs AT 270 has as the Google Nexus 7 has a resolution of 1280 x 800 pixels. Unlike its competitor, the AT270 but uses the AMOLED display technology. Pixel black image content is completely switched off. This saves power and is especially popular for real black. The result is an intense color reproduction. Unfortunately, the maximum brightness of 295 cd / m² is not particularly high. The readability is due to the AMOLED technology but also ensured in bright environments, unless you work in the blazing sun. Reflections keep within limits.

The angle at which you hold the pa3819u-1brs AT270, hardly plays a role: The viewing angles are stable, inverting the colors can not be seen. Only the brightness decreases at steeper viewing angle somewhat.

The Toshiba pa3479u 1brs touch screen takes a little more finger contact as many of its competitors. Movements are then implemented with precision and reliability. The glide also fallen, so that fleet action or racing games do not mutate to motor insurmountable challenge. From scratching the screen is protected by Gorilla glass surface.

Of the leading group of Toshiba pa3635u 1brm tablets but these results are far away. The tablet is usually at or just below the performance of the Google Nexus 7 with weaker dual-core processor from Texas Instruments. When AT270 CPU and operating system seem to have been designed not particularly effective way. In his Transformer Pad Asus proves example, that the combination of Android and Tegra 3 processor can harmonize much better.

The Webperformance falls from passable to uproot trees without. 2084.2 ms in the SunSpider test browser and 1246 points in Vellamo benchmark fall against the Nexus 7 1701.4 ms, respectively, with 1752 points from something. Navigating pages succeeds but then quickly and without stuttering. For the cozy on the couch surfing it arrived anyway.

The Toshiba is a stylish alternative in the 7-inch segment of the Toshiba satellite l300 battery tablet. With 32 GB memory and microSD slot for intensive data collector is enough space. Equally positive is that the 7-inch device remains cool even at higher loads and is pleasant to hold. Like low weight and a sleek aluminum case. The built-AMOLED display is good. The viewing angle is small, tidy the sharpness and colors enjoyable. In bright conditions, it can be due to reflections but not read very well.

For currently Toshiba satellite a300 battery around 250 euros less to offer the Nexus on the 7th Performance-wise equal, it has an IPS display and is also well made. However, Google also dispensed with the base models on a 3G modem, and a rear camera and a memory card slot is not obstructed. Add a noticeable heat coming under strain. Nevertheless, the price is attractive: there, the 16-GB model costs as little as 199 euros, with 32 GB and it costs 249 with 3G module and 32GB of internal memory, the price is currently at 299 euros.

A compact camera for under 75 euros - a little can go so well? The test revealed: The Canon PowerShot A810 shows class-typical defects of the image quality and the speed of the autofocus. For this, the A810 is due to the ease of use suitable for beginners.

The good news first: The PowerShot A810 is small (95 x 61 x 30 mm), lightweight (175 grams) and thus fit pants pocket. And canon nb 5l battery does not cost much at online retailers can order them already for under 75 euros. Good arguments for a purchase? With security. Especially since the controls are nice and big and easy to take in what just older people makes using the camera. There is also a question mark button that says beginners basic functions at your fingertips.

Long battery life
Furthermore, the A810 uses standard AA batteries or rechargeable Canon nb 4l battery. In practice, this leads to an amazingly long period from 340 to 1150 photos. A pleasant side effect of this power solution: The space required for the AA cells, something like a handle on the right side, so the camera is very handy.

5X zoom and many effects
The canon nb 6l battery A810 offers a 5x zoom that covers a focal length range from 28 to 140 mm (according to small picture). The light strength lies in good f2, 8 in wide and weak f6, 9 telephoto setting. An image stabilizer is missing. The camera screen of the A810 measures 2.7 inches and also only 230,000 dots - a secure control of the sharpness is so difficult.

Video records the PowerShot 720p with mono sound. Is a manual shooting mode, it neither video nor photos, but this is as expected at this price range. Only the white balance, you can influence. Various effects programs invite for distorting the images, as with fish-eye, miniature or toy camera effect.

Image noise and weak details
The resolution is increased in comparison with the predecessor Canon lp e8 battery A800 clearly. Offered these ten megapixels, the A810 has to offer now 16 megapixels. But 60 percent more sensor resolution on balance lead to a slightly lower quality. Even at ISO 100 in the 100-percent view on the PC monitor noise can be seen in the pressure drops but only from ISO 800 to truly negative. The maximum resolution increases only slightly to a maximum of 1393 line pairs per picture height. The attention to detail can already at ISO 400 by clearly visible. Fringing the edges of objects are visible in wide angle as Tele with two pixel intensity.

The autofocus is too slow for snapshots. In the laboratory we determine a shutter lag of 0.69 seconds at wide angle and telephoto setting of 0.81 seconds. The time at power and the image processing talks to around two seconds acceptable.

Canon PowerShot cheapest compact camera offers a reasonable price to the equipment, which includes what is necessary for occasional photos. By easy, intuitive operation and large buttons, the A810 is also suitable for the elderly. The canon eos 550d battery picture quality reflects the competitive price again. In daylight it's fine, low light noise disturbs and lacks details. The autofocus is too slow for snapshots.

The networking opportunities are a bit disappointing. The HP Pavilion Sleekbook b14-B000ed has a permanent network connection that is only 100 Mbit / s can get: gigabit is not possible. Furthermore, the only suitable for 2.4 GHz WiFi networks up to 150 Mbit / s. Too bad that HP has saved this.

The HP has a total of three USB ports, two of the USB 3.0 type. There is also an SD card reader and a standard HDMI connection. VGA is missing. Unlike most Ultrabooks you with this HP 540 battery replacement. For the rest, the HP an average laptop with a keyboard with a reasonable attack, though it bounces along pretty well. Also, the touchpad is relatively small. Wipe from right inside, open the touchpad automatically Windows 8 Charms along the screen.

The Sleekbook has no Beats Audio, but speakers from Altec Lansing, combined with 'Dolby Advanced Audio. We once heard worse speakers, but it is not impressive.

Technique

The processor in the HP pavilion dv3500 battery Sleekbook b14-B000ed is an Intel Core i3 3217U, a processor from the Ivy Bridge series. This is a relatively new chip, because until recently were still Intel's Core i3 used in the Sandy Bridge series, which are quite slow. He works at 1.8 GHz, has 4 MB cache and Hyper Threading. Especially in graphic terms, the Intel HD Graphics 3000 a lot slower than the Intel HD Graphics 4000 of the latest Intel processor series. The main reason why this processor is slower and cheaper than the i5's is the lack of a Turbo-mode.

The HP Pavilion Sleekbook b14-B000ed (C5R96EA) is not a laptop which we are very warm. It works fine, but the spell on the battery is disappointing, the performance of the HP mini 311 battery system as a whole are not particularly well screen is no winner.

If you are in this class are shopping there is quite a lot for sale, for example, the ASUS X202E. This model is lighter, smaller and with a touchscreen. This makes it a strong competitor for this model of HP and in our opinion a more interesting choice. It is perhaps more interesting as this HP product for some lower price in the market place.

Lenovo presents the ThinkPad Twist another rather unusual convertible notebook with Windows 8, and a 12.5-inch screen and rotatable. From the Ultrabook arises in no time a tablet PC for easier finger or stylus or a handy tool for presentations.

The term tablet existed long before iPad, Galaxy Note, HD and Co. A Nook Tablet was then a Windows-based device, which spent most of its existence as a traditional laptop ThinkPad t60 battery and its display was turned on his back when needed, so that the device could then be used as a touch-screen slate PC. Lenovo and HP are among the most important of the few big producers that the Windows-based convertible notebooks during the barren years before the iPad Revolution held with systems such as the Lenovo IdeaPad S10-2 and the HP TouchSmart TX2 alive.

Nowadays Tablets, hybrid devices and Convertibles are against omnipresent and available in unlimited quantities. The scope ranges from devices such as the Sony Vaio Duo, which is simply pushed to the laptop via the Dell XPS 12, the ThinkPad t61 battery display is simply rotated in the display frame, up to the Lenovo IdeaPad Yoga, the display is folded out of the notebook mode simply backwards and it does so for Tablet. But the classic convertible design - ie a display that is rotated on a central hinge and then folded over the back of the unit - we have not seen in a long time.

Thus, the Lenovo ThinkPad twist is, in a sense is a technical antique - and it need not be necessarily bad. Because convertible notebooks with central rotary hinge should be very familiar to many users that before 2010 a Windows tablet called their own. The design is of course not as fancy as the futuristic Convertibles from Dell or Toshiba, but just business users, it may be more familiar - and that brings with it a certain feel-good effect with it. Add to that the typical ThinkPad-solid construction, an IPS panel, and Lenovo's usual range of user-friendly configuration and support software.

In the price range of the tested about 950 euros expensive Core i5 configuration of the ThinkPad t500 battery twist it would be difficult for investigators at any rate, to find a higher quality device. Who to look snazzy emphasis is, with the twist probably used incorrectly - it really looks as though it was just after a jump in time from the year 2009. But business users and home users with little design claims get here missed the full, classic ThinkPad broadside, which in this case also includes touch functionality under Windows 8.

Design, equipment and display

Lenovo is long gone, the company that just produced only professional ThinkPad. Meanwhile, Lenovo also manufactures the imaginary for occasional private use IdeaPad notebooks and favorable Essential equipment. Within the ThinkPad t61p battery family there's also the Edge series, which the classic ThinkPad design to modern aspects - for example, the keyboard in island style with the low-profile keys, the keyboard-less click-pad and a total leaner and sharper design - expanded.

The twist seems to look like it was taken from the Edge series, it is in name but not assigned. The laptop has. Slightly rounded corners, a thin despite the touchscreen technology display lid and the modern looking keyboard with flat keys, which are found in more and more Lenovo products

With its matte black finish, the lenovo y510 battery notebook fits into office environments and falls with a height of two centimeters in the café is not negative. An attention magnet like Acer's Aspire S7 or Lenovo own Yoga Ultrabook, it is not yet.

The distinguishing physical feature of the Twist is its central display hinge. Rotates the display horizontally in the hinge 180 degrees, so that the screen then suddenly away from the user shows. That in itself is an extremely useful item, as soon as you can a small audience present content without having to turn the notebook yourself. So you can, for example, show the entire space on the fly a presentation, for example, but also in the hotel watching a movie without the keyboard is in the way.

Lenovo has unveiled at CES 2013 new, especially handy mobile companion with touchscreen and Windows 8. When 11S IdeaPad Yoga is a convertible Ultrabook with 11.6-inch display, Ivy Bridge processor and so-called "multi-mode" functionality

The IdeaPad Yoga 11S and ideapad y450 battery has as its closest relatives through a particularly moving display hinge, which helps rotate the screen almost at will and can tilt. Thus the device four modes are available, including the notebook and the tablet mode. The other two called Lenovo as "state" and "Tent".

The unveiling weighs 1.4 kg and according to the manufacturer is 17.2 millimeters thick. The 11.6-inch display with 1,366 x resolves to 768 pixels, and uses IPS technology is protected by Corning Gorilla Glass from unpleasant minor injuries.

Inside the Yoga 11S and ideapad y430 battery is an Intel Core processor of the third generation type Core i5 or Core i7. Intel's CES press conference was to learn already, that it should be installed at the chip at one of the upcoming CPU models with 7-watt TDP.

Compared with adult Ultrabooks bring the hybrid concepts based on Android with a decisive advantage in battery life. Up to 18 hours to the combination of keyboard dock and tablet hold the Lenovo IdeaTab S2110A. The total weight of the combination is then no longer record: almost 1200 g load the luggage. The MacBook Air with its larger 11.6 inch display puts it, for example, to 1080 g, but even with five hours of battery life by much shorter.

The decisive factor in the hybrid concepts, no matter what device classes are now combined, is the consistency of the individual components. What use is a good keyboard when the tablet can not convince, and vice versa? To come straight to the point: Lenovo has done his homework and eliminates most criticisms of the 7-inch device IdeaTab 2107A at the new product presentation.

Specifications Lenovo IdeaTab S2110A

Display: 10.1-inch IPS display, 1280 x 800 pixels, glossy
Processor: Qualcomm Snapdragon dual-core APQ8060A (1.5 GHz)
OS: Android Ice Cream Sandwich 4:03
Memory: 1 GB RAM
Storage: 16GB eMMC Flash
Tablet Interface: Micro-HDMI, micro-USB power port
Interfaces keyboard dock: USB power port, 2x USB 2.0
Connectivity: WiFi 802.11n (b / g / n), Bluetooth 4.0
Sensors: Light sensor, speed sensor, position sensor
Dimensions / weight Tablet: 259 x 178 x 9 mm / 564 g
Dimensions / weight keyboard dock: 265 x 190 x 23 mm / 632 g
Battery : 6Cells ThinkPad t400 battery
Other features: 5 megapixel camera (rear) with flash, 1.3-megapixel camera (front), GPS, SD memory card slot in the dock.

The tablet can be twisted easily, creaks but not least. Therefore when twisting the screen brightness varies and it is disturbing effects show on the display when you press on the back side near the frame. Particularly stable does not the back wall. The ThinkPad sl410 battery plastic back has a diamond-shaped structure, which it feels rough, but not unpleasant.

The keyboard dock is mounted on four rubber feet that provide on smooth surfaces as good as any grip. The device slips easily. Warping the images reveal the base unit. The work surface is according to pressure. Overall, the keyboard dock looks but robust.

The lenovo y510 battery tablet is stuck in the display hinge. When operating, it shakes and bounces slightly. The hinge itself has been very powerful holds, but not good. If you lift the device, the tablet tilts time already fully back. 90 degrees of inclination from the hinge lifts the keyboard dock at the back so that it reaches a slight tilt. A practical effect that has not, as the increase is too small to affect the tap.

As connections Lenovo built in tablet portion only a headphone jack, a micro HDMI port, for example, to video on an HDTV-capable monitor or TV output and a Micro-USB port for power and synchronization with the PC.

The ThinkPad t60 battery keyboard dock has a little better. Two full-size USB 2.0 ports are next to a micro-USB socket on the left page. Front, there is a SD card reader. Which one would also want the tablet, such as a microSD version, so that people without keyboard dock access to multimedia content have an SD card.

The tablet is not only slim, but for a 10-inch model with 564 g also one of the lightest in its class. Against it the ThinkPad sl500 battery hard keyboard dock with 632 g. Together the combination is therefore crucial to 1195 g - this is not "unacceptable", but loaded the luggage but then more than suggested by the small size allows.

Lenovo donated both the tablet and the keyboard dock, a battery with 23 watt hours. The battery on the keyboard dock also charges the tablet battery if it should no longer have the full capacity.

We put the screen on full brightness and had a YouTube video in full screen mode via wireless play continuously. Alone with the dock battery lasted through the Lenovo IdeaTab about 4 hours and ten minutes. Given the brightness of the display is a very good value. The runtime could not be determined exactly: About 20 minutes for the battery capacity indicator stood at Tablet to 100 percent when keyboard dock to 0 percent. One of the ads must be wrong, we touch on the subject to the keyboard dock.

At the Cebit as Dell, we can get an idea of ​​Latitude XT3. The 13.3-inch Convertible Book is currently used with different processors of the Sandy Bridge platform, HDDs or SSDs and the Intel HD Graphics 3000, therefore.

The appearance can be described as not very graceful but it rock solid. And this impression is deceptive. Twists are completely alien to the Book and the palm rest, and side edges present themselves extremely stable. The rotation and tilt mechanism also gives a solid picture. With two handles of the notebook is a tablet and vice versa.

Gone are the days where the user had to use expensive 1.8-inch hard drives or SSDs. The former are mainly slow and SSD is a great choice, it is not even in the same format. Our XT3 is equipped with a 2.5-inch SSD from Samsung (PM810).

Perhaps most striking is the design itself. Instead of 12, there are now 13 inches in diagonal. The Latitude XT3 and Dell latitude e6400 battery has a resolution of 1,366 x 768 pixels and is thus prepared for Windows 8 and the Snap feature. The predecessor had 1,280 x 800 pixels. The weight of the device is nearly 2.2 kg by the new construction unfortunately much higher than that of its predecessor at 1.73. The XT3 is also very thick with 33 mm. Therefore, the display can now rotate in both directions.

The rest of the equipment meets the stringent requirements of companies. A 3G modem - but without CDMA option - there are just as a dual-band wireless card from Intel. Is a connection for ExpressCards it for extensions also, as a backlight. The equipment varies greatly in part because the users themselves can choose their components.

The Dell studio 1555 battery display of the exhibition model is antireflection (Dell also offers a glare-variant). The luminosity does not reach peak values, but ranges from a completely trouble-free operation in the bright halls. The keys of the conventional keyboard have a clear pressure point for medium extension, but when it stops giving an easy flap-engine noise. In the business sector are not atypical mounted above the multi-touch pad mouse for: They have a long stroke, which prevents accidental actuation.

Furthermore, the pointing device can also be used over the functions integrated in the keyboard trackpad. An additional business features are not lacking. On board are fingerprint, Firewire (1394), docking station port, smart and ExpressCard slots.

Total returns the Dell Latitude XT3 and Dell latitude d630 battery from a very convincing performance. For the Convertible Book with Windows 7 Dell, however, requires a high price. This may vary depending on equipment ever break through the 2000 Euro mark.
