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.

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.

Toshiba AT270-101 display review

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.

Test: Canon PowerShot A810

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.
