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.

This is a test report on the new Panasonic FZ48 integral lens camera. The camera looks like a compact SLR. It has a big grip on the right hand side of the body, which allows for comfortable handling for shooting, important for a long-range zoom such as this.

On-board image processors have become more powerful and diverse in their functions, and cameras like the Ricoh GR Digital IV ($649) offer more than just point and shoot still and video recording. Indeed, the Ricoh seems designed to appeal to those who would rather have their special effects in hand than take the time to apply them later. But the camera offers more than just tricks, though there are plenty of those, and its portability, ease of use and flexibility might appeal to those who want to go beyond cell phone snapshots and effects. Its fast, fixed focus lens, aperture- and shutter-priority exposure modes and a host of Scene modes that go beyond the norm make it a fascinating study in the state of photography today.

The Samsung NX200 is a Compact System Camera (CSC) with an interchangeable lens system. It is based on an APS-C-sized sensor and Samsung’s NX-mount system, which currently comprises nine Samsung lenses. The range of lenses will be expanded this year, with the latest being the Samsung 85mm f/1.4 ED SSA, which is a fast portrait lens that supports Samsung’s i-Function technology. The lens ring—which is normally used for manual focusing—can be used for i-Function settings, a very handy feature that can be programmed by the photographer to change various settings right from the lens.

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 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 new SLT-A99 is Sony’s first full-frame camera with an electronic viewfinder. While former Sony full-format cameras like the A900 or A850 offered a standard SLR system, the new A99 offers an electronic viewfinder with extremely high resolution (2.3 million RGB dots). Due to the SLT system with fixed mirror, which allows use of a classic AF system based on phase detection, the camera is very fast and can even utilize the AF system while recording videos.

The Sony HX200V is a compact bridge camera with an SLR-like design. It offers an extreme zoom lens that is able to cover wide angle shots with a focal length of 27 mm and tele photos with an extreme tele of 810mm (35 mm film equivalent). The camera offers an integrated image stabilizer (Sony’s “Steady Shot”) to allow shooting with this extreme zoom range. This stabilizer works fine, but can’t really help if you are using the digital zoom function, which allows a 60x zoom, an equivalent of 1620mm.

The NEX-6 offers an APS-C-sized CMOS sensor with 16MP resolution, the Sony NEX E-mount system, a large swivel screen on the back, a high-resolution electronic viewfinder, and a Wi-Fi module for wireless data transfer or remote control. This very small system camera uses a large mode dial on the top to set up exposure modes directly instead of using the menu on the screen (unlike other NEX cameras). Directly below this mode dial there is an additional dial to change image parameters. The photographer can use this second dial and the third dial (which encircles the cursor field) to change aperture and shutter speed settings directly, which makes it as comfortable to operate as an SLR system.

The Sony NEX-7 is a compact camera with an E-mount system and an extremely high resolution (24MP). The metal body is very robust and sports a stylish retro design, which offers new features like two additional setup dials to change image parameters. These setup dials, located on the camera back and accessed using the right-hand thumb, are integrated seamlessly into the body and nearly invisible when looking at the camera from the top.
