The Nikon D4S is a professional SLR system for sports and action photography. It has a full-frame sensor (36x23.9mm) that Nikon calls the “FX” format. In combination with the new EXPEED 4 image processing system, the new sensor offers an extended ISO speed range: the “native” range is between ISO 100 and 25,600, with an additional high mode equivalent of ISO 409,600 (!). The noise results are impressive in the native ISO range, while images with ISO 102,400 and ISO 204,800 show nearly the same noise artifacts as APS-C cameras in the ISO 12,800 to ISO 25,600 range.

The D5200 follows Nikon’s D5100 and offers a new sensor with higher resolution (24MP instead of 16MP in the D5100). The new camera has an APS-C-sized CMOS sensor and uses a fast and reliable AF system with 39 focus sensors, including nine cross-type sensors. The photographer can toggle between different AF modes with nine, 21, or 39 points with dynamic-area mode and use predictive focus tracking for moving subjects.

The Nikon D5300 follows the Nikon D5200 and there is an important difference between the two. The D5300 has a new image sensor without a low-pass filter, which contributed to an excellent performance in our resolution tests.
The D5300 uses a display with a 3:2 aspect ratio, which shows the whole sensor image without black borders or frames. Compared to the Nikon D5200, the LCD screen is also larger, at 3.2”, and has a very high resolution of 1.04 million RGB dots. The monitor is fully articulated and makes for very comfortable shooting.

The Nikon D600 is the smallest of the company’s full-format sensor cameras yet due to the same seals and protections as the Nikon D800 and its very robust body, it can be used outdoors under rugged and rainy weather conditions.

The Nikon D7100 is the newest of Nikon’s D-SLRs with a DX sensor (APS-C size). This is a new sensor without a low-pass filter, a very unique feature in this class because nearly all compact and SLR cameras use low-pass filter systems to avoid moiré and aliasing effects. The sensor has a resolution of 24MP (6000x4000 pixels). We did our tests with the kit version of the D7100, using the AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR, said to be optimized for DX cameras.

The Nikon 36MP D800 has a “full-format” sensor with a resolution normally associated with digital backs, making it a competitor with medium format cameras made by companies such as Hasselblad or Phase One. The camera will be available in two versions: a standard version, which was used for this test, and an additional version dubbed the D800E, which does not have a low-pass filter. The conventional thinking on use of a low-pass filter is that it avoids color moiré, although inclusion of the filter can create a certain amount of softening of image details. To avoid this soft look many medium format cameras or digital backs do not use it. In those cameras with the filter the effect is reduced via digital filtering in their Raw converter software. (We will do another resolution test on the D800E when it becomes available.)

The Nikon D800E contains a 36MP full-format FX sensor, a resolution normally associated with digital backs. This makes the D800E a competitor with medium format cameras made by Hasselblad or Phase One. The “E” version of this camera is contsructed without a low pass filter, used in many digital cameras to avoid color moiré but that can create a certain softening of image details. To avoid this soft look, many medium format cameras or digital backs do not utilize this filter. In cameras that use the filter, moiré effects are filtered in their raw converter software.

The Nikon Df is a retro-style SLR camera with a 16MP full-frame sensor. While other Nikon SLRs, such as the D4, are clearly aimed at the professional and enthusiast markets, with all the attendant features of modern D-SLRs, the Df is clearly a “classic” camera approach, intended for “purists.” That may be the reason why the Df offers no video capabilities, for example.

The Olympus E-P5 has a classic viewfinder camera design but doesn’t have an optical or electronic viewfinder. It does have a swivel monitor which can be folded up- and downward and offers very high resolution (1,037,000 RGB dots). Its 3:2 aspect ratio shows additional information on both sides of the viewfinder image, which has an aspect ratio of 4:3 when taking images in the highest image resolution setting. By pressing the “OK” button in the center of the control field additional parameters are shown as overlays on the right-hand side of the live view image.

The new Olympus OM-D E-M1 is the follower of the first OM-D, the proper and full name having been the “OM-D E-M5.” The E-M1 incorporates many of the E-M5 advantages, the famous five-axis image stabilizer being one of them. This image stabilizer is based on sensor-shift technology and allows the user to shoot a stabilized image with every lens system mounted to the camera.
