Our initial report on the Canon EOS-1D X appeared in the Image Tech section of our homepage at www.shutterbug.com and was based on a preproduction model. This is our final report based on a factory-ship model.

The S1 is the brand new entry-level camera in Nikon’s 1 series. With a sensor resolution of 10 MP it offers the same nominal resolution as the first Nikon 1 cameras, the 1 J1 and 1 V1, which were launched in 2011.

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 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 Nikon Coolpix P7700 offers numerous function buttons to change image parameters and exposure modes very quickly and efficiently. On the top side of the large body are three dials. The first dial on the left-hand side allows the user to set up the most important image parameters like ISO speed, white balance, and image quality (resolution and JPEG compression) directly. The LCD shows the chosen image parameter setting on the screen when the photographer turns the setup dial and presses the center button.

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 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 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 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 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 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 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.
