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.

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.

The RX1 is the first time Sony has combined a compact camera system with a fixed lens system that includes a full-frame sensor that’s nearly the size of classic 35mm film material (35.8x23.9mm). The basic camera concept combines elements of digital compact cameras with features of classic viewfinder cameras, but leaves out an optical or electronic viewfinder. In its stead Sony offers an LCD screen on the back, similar to what you’d find in an entry-level compact camera. The screen is very large (3”) and offers a very high resolution (1.28 million RGB dots). The resulting image preview and the representation of the menu structure is crisp and clear. Sony does offer an optional optical viewfinder, which is mounted on the hot shoe. Just like the camera itself, it is quite expensive. Most users will also be surprised by the battery recharger system of the RX1. It’s equipped with a USB recharger and the user is forced to recharge the battery in the camera. An external recharger and additional batteries are offered as an option.

The new Canon G1 X quite an extraordinary camera. It has thecompact body of a high-end point and shoot camera with a large CMOS 18.7x14mm sensor delivering 14 MP. This sensor is larger than Micro Four Third sensors (17.3x13 mm) in Panasonic or Olympus CSC cameras.

The Samsung Galaxy is a new type of camera that’s more like a tablet computer with an integrated camera system. However, rather than using a small low resolution camera module (like smart phones and tablet computers) it offers a “real” camera module with an ultra zoom lens. This lens system offers a 21x zoom lens with a focal length of 23 to 483mm (35mm film equivalent).

The Pentax WG-1 GPS is a compact camera with a 5x zoom lens (28-140mm) and a robust body, which is water proved to 33 ft, shock proof (5 ft drop down) and an integrated GPS system. The camera offers 14 MP resolution and some extraordinary features like “Digital Microscope” mode.

The Samsung NX11 is the follower of the NX10. Like the NX10 it is a compact system camera with an APS-C-sized sensor and a nominal resolution of 14.6 MP. The most important difference to the NX11 is the “i-Function” technology, which allows the user to set up image parameters very quickly and intuitively. The NX11 offers this technology right out of the box; the NX10 now offers “i-Function” via a firmware update.
