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 Panasonic G5 is a very compact mirrorless system camera that looks like a small SLR, yet has an electronic viewfinder. The EVF has a very high resolution of 1.4 million RGB dots and shows a very crisp and clear image.

The camera is designed for use with the new X lenses made by Panasonic. These lenses have an integrated motorized zoom and servo-controlled focusing system. To accommodate use of the lenses the G5 offers a zoom switch to change focal length rather than a lens ring, just like when using a compact camera.

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 new D4 is a typical Nikon professional system: it’s extremely massive, very heavy, and all function buttons, card slots, and any other notches are sealed to prevent the intrusion of dust or rain. The camera offers two high-speed modes and is able to record 10 or 11 images per second in full 16MP resolution. In our tests the camera was able to consistently achieve this high speed. The camera uses a new shutter system based on Kevlar fibers that allow up to 400,000 exposures. With its high speed, robust shutter system, and robust body, the Nikon D4 is a clearly aimed at photojournalists and sports photographers.

The Pentax Optio WG-2 GPS is a rugged camera that is waterproof (maximum depth: approx. 40 feet) and shockproof. The camera offers a 16MP sensor and a 5x zoom lens with 28mm wide-angle and 140mm tele settings (35mm film equivalent). It is the follower of the WG-1 and shows some improvements in image resolution and configuration. Its unique body design is indicative of the “tough camera” class and is designed for use by photographers who want to dive or use this camera for downhill mountain biking or other “adrenaline sports.”

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 Canon EOS Rebel T4i offers the same sensor resolution of 18MP as its forerunner EOS T3i, but shows a lot of improvements in handling and functionality due to a new image sensor and a new image processor. The camera is Canon’s first D-SLR with a touchscreen. This screen is very large (3”) and has a very high resolution of 1,040,000 RGB dots. It is a swivel monitor that can be flipped up- and downward and tilted to the front (for self-portraits). Even though it is a touchscreen, the whole handling of the camera (menu structure, parameter setup) is still oriented on Canon’s SLR handling scenario. In contrast to many compact cameras with touchscreen-oriented operation, the touchscreen isn’t mandatory, but it’s still helpful.

The Olympus OM-D is a retro-style camera that harkens back to the OM System of the 1970s and 1980s. In the current Olympus lineup, this Micro Four Thirds system camera sits somewhere between the PEN cameras and the E-System cameras. Like the PEN, it offers a very compact design and many helpful features for beginners, yet the design is oriented toward a classic SLR.

The Canon SX40 HS is a compact bridge camera with an extreme zoom lens. It offers focal length settings between 24mm and 840mm (35mm film camera equivalent), which allows users to shoot nice wide-angle shots to extreme telephoto images. Adjusting the zoom lens between 24mm and 300mm is easy and allows a nearly continuous setup of the desired field of view. However, zooming between 500mm and 840mm requires more work.

The new Fujifilm X-Pro1 has a stylish, retro design with many interesting features. It is Fujifilm’s first compact system camera with Fujifilm’s new lens mount system. Fujifilm currently offers three lenses for the “X mount”: the XF18mm f/2 R, the XF35mm f/1.4 R, and the XF60mm f/2.4 R Macro. We used the 35mm lens for all our test images and the 60mm lens for the portrait test shot.

The HS30EXR has a surprisingly heavy and massive body and is nearly the size of an entry-level SLR system combined with a superzoom lens. The grip on the right-hand side fits perfectly into the photographer’s hand, while the left hand supports the lens system and is used to change focus and focal length manually with two large lens rings. The focal length ring has a nice rubber coating and is easy to handle, while the focus ring is very thin and is located near the body of the camera, which makes it a bit less easy to handle. Focal length adjustment is done via a mechanical regulation of the lens system, while the focusing ring adjusts via a servo system.

The Panasonic GX1 is a very compact system, smaller than their G3 model, but slightly larger than the Panasonic GF3. It could be thought of as Panasonic’s competitor model to Olympus’s PEN cameras and to Fujifilm’s X100. The camera is based on the Micro Four Thirds system and has an MFT sensor with the highest resolution available today (16MP). We tested the kit version, which is bundled with the X Vario 14-42mm lens, a new pancake version of the standard zoom lens. It is a motorized zoom system that provides smooth zooming when recording videos. The camera is able to record Full HD video in AVCHD mode and uses a stereo microphone on the top to record sound.

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 D3200 is Nikon’s new entry level SLR with an outstanding nominal resolution of 24MP. The camera uses an APS-C sized CMOS sensor 23.2 x 15.4mm in size, Nikon’s DX format.

The camera offers a lot of help to beginners; just like the forerunner D3100, the D3200 offers a special “Guide” mode. When using this mode and starting the D3200, it will ask the user whether he or she wants to shoot, to review or to setup the camera menu. If the choice is to shoot the camera“asks” whether the user is an absolute beginner and needs “easy operation” or an advanced user who wants “advanced operation.” If an absolute beginner, the D3200 presents short descriptions of some typical photographic situations and sets up all parameters accroding to how the photographer responds.

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.
