Like a standard compact camera, the Pentax Q system uses a very small sensor system, 1x2.33”. It offers an interchangeable lens system with the new Q mount. Pentax offers three lenses: a standard zoom (5-15mm f/2.8-4.5, equivalent to 27.5-83mm), a fisheye lens (3.2mm f/5.6, equivalent to 17.5mm), and a third, with which we did our tests, a fixed focal length of 8.5mm, equivalent to 47mm. Pentax brands this lens as the “Standard PRIME 8.5mm f/1.9 AL [IF].” Pentax also offers two additional “Toy” lenses with a fixed aperture size: the Toy Lens Wide 6.3mm f/7.1 and the Toy Lens Tele 18mm f/8.

The Samsung NX20 is a mirrorless system camera with very high sensor resolution. Just like the Samsung NX200 it uses an APS-C-sized sensor and offers a resolution of 20MP. In contrast to the NX200 it uses an SLR-like body design and an electronic viewfinder with very high resolution. The EVF has 1.44 million RGB dots and offers a very brilliant and sharp image, which makes manual focusing very comfortable. In addition, the NX20 has a large AMOLED swivel screen on the back with a resolution of 614,000 RGB dots.

The Samsung NX30 is a mirrorless, Compact System Camera (CSC) with a classic SLR design. It offers an electronic viewfinder with 2.36 million RGB dots instead of an optical SLR viewfinder. The viewfinder offers an exceptionally brilliant, sharp, and detail-rich image, which easily allows the photographer to shoot in manual focusing mode.

The NX300 follows the company’s NX210 and updates many features. Its new WLAN system, for example, now supports 2.4GHz and 5GHz systems for better data transfer. (Note: 5GHz systems eliminate interference better than the older 2.4GHz standard.) The free Wi-Fi connection can be used with remote control software on Android or Apple iOS smartphones, for auto backup on the PC, and for various mobile link functions, like sharing images by e-mail or in social networks.

The Sigma DP2 Merrill is dedicated to Dick Merrill (1949-2008), a photographer and engineer who developed/invented the Foveon sensor technology. The camera is based on former DP compact Sigma cameras, but uses the newest generation of the Foveon X3 sensor. This sensor records all three RGB values for every single pixel and has an image resolution of 4704x3136, or 14.75MP. Because of the multiplication of three RGB layers, the camera gains a “resolution” of 44.25MP. Officially, Sigma specifies the resolution of the sensor even higher: the spec sheet uses the gross resolution with 4800x3200 pixels (x three layers) and therefore indicates that the camera has a resolution of 46MP.

The Sigma DP3 Merrill is the latest Sigma camera with the new Foveonsensor.
With this sensor, the camera can capture complete RGB information for every single pixel and doesn’t need to interpolate colors like all other digital cameras with Bayer pattern sensors. The APS-C sized sensor offers a resolution of 14.7MP, referred to by Sigma as equivalent to 45MP resolution of a standard sensor ((4704 x 3136 pixel x 3 RGB data per pixel).

The Sony (alpha) A57 is based on Sony’s SLT viewfinder system that uses a fixed and semi-translucent mirror. This enables viewing via a live preview on the LCD screen on the back or through the electronic viewfinder. In addition, the mirror reflects the image onto an AF sensor based on the classic phase detection system used by “normal” SLR cameras. The AF sensor works continuously because there is no moving mirror system to cover the sensor when the picture is taken. This aids in continuous shooting speed and when recording videos.

The Sony A65 is a feature-reduced version of the company’s A77 model. It offers a nominal resolution of 24MP (just like the A77). The A65 uses Sony’s SLT system, which combines a semi-translucent mirror system and an electronic viewfinder. The semi-translucent mirror reflects a part of the light to the Phase Detection AF sensor, which is located in the penta-prism bulge on the top of the body and allows for very fast focusing. At the same time, the image sensor is able to generate a digital live preview for the LCD on the back or on the mini LCD screen of the ELV. Both monitor systems use high-resolution LCDs. The large monitor on the back offers 921,600 RGB dots; the AMOLED ELV offers 2.3 million dots for a brilliant and crisp image.

The Sony A37 is an SLT system with a fixed and translucent mirror. Because of this setup it is able to produce a Live View image even while recording still images or shooting video. At the same time, the camera is able to use its Phase Detection AF system because the mirror reflects the image onto the AF sensor. This allows the use of the AF system even in continuous shooting mode. The camera offers a high-speed burst mode of up to 7 frames per second, which is a very high result for an entry-level system.

The Sony A7 and A7R are the first mirrorless system cameras with a full-frame sensor. The A7 offers a sensor size of 35.8x23.9mm and a resolution of 24MP, while the A7R has a slightly larger sensor at 35.9x24.0mm and 36MP resolution. Both cameras use the E-mount lens system that was introduced with Sony’s NEX cameras. Because NEX cameras use APS-C-sized sensors all previous E-mount lenses have smaller image circles, thus the full-frame models require new E-mount lenses, which cover the larger image circle of a full-frame sensor.
