The D7100 is Nikon’s newest SLR camera with a DX sensor (APS-C size). It has a brand new sensor with 24 MP and without a low-pass filter. It offers simple automatic and scene modes for beginners and a lot of individual set-up and exposure features for professional photographers.
Comments on Image Quality
Colour: The camera is able to reproduce colours very exactly. The automatic white balance system did a perfect job in nearly every lighting condition and created very neutral colours. But it also shows a tendency into a very saturated colour style, especially the blue and red nuances of our test chart. This causes a mean/average saturation of more than 112 percent and, therefore, a very high saturation result for a professional SLR system. On the other hand skin tones are reproduced nearly perfectly.
Sharpness: The resolution results are excellent. The camera reproduced the ISO 12233 chart with 3.911 lines in picture height, which relates closely to its nominal resolution of 4000 lines. The images have a crisp but still very natural-looking appearance. During our tests, we had absolutely no problems with moiré or aliasing effects. Even shots of fine detailed structures (front of an office building with blinds in its windows, fine structures of fabric, lines in Siemens stars in our standard test box shot and more) are reproduced neatly and cleanly. Some aliasing effects are noticeable in video shots taken with the D7100, but they are still on a lower level than in videos taken with some Sony SLT cameras, for example. Considering the missing low-pass filter this is a surprising result.
Noise: Noise results are very good. Luminance noise shows a slightly higher level than in images taken with cameras with APS-C sized sensors and lower image resolution, but the look of the final images is very good. Colour noise is filtered efficiently, and the final image shows only a little grain, similar to the grain of analogue film material.
The camera also performed excellently in our dynamic range test. It scores up to 11.5 f-stops in lower ISO speed modes and keeps a high level of more than 10 f-stops up to ISO 3200 mode.
Comments on Handling
The Nikon D7100 is the newest top-of-the-line product of Nikon’s SLRs with DX sensors (APS-C sized sensors). It uses a brand new sensor without a low-pass filter. This is a very unique feature because nearly all compact and SLR cameras are using such a filter system to avoid moiré and aliasing effects. Only digital backs for medium format cameras (Hasselblad, etc.) and some special versions of SLRs like the Nikon D800E surrender/give up such a filter system.
The new D7100 sensor offers 24 MP (6000 x 4000 pixels). We did our tests with the kit version of D7100 that included the AF-S DX NIKKOR 18-105 mm 1:3.5-5.6G ED VR, which is optimised for DX cameras.
The camera has a massive and robust body. It has a classical SLR design with a bulky handle on the right-hand side, which allows stable and secure handling of the camera. A large and illuminated LCD screen on the top shows all necessary image parameters and additional information.
The camera is very fast. Shutter delay and start-up time are low and, therefore, on a professional level. The camera can record up to 6 frames per second in full resolution (24 MP).
Its AF system offers 51 sensors (15 cross-type sensors) and shows a very quick response when pressing the shutter release button halfway down. The user can change the AF sensor set-up and define the AF area in the image centre with 9, 21 or 51 sensors, for example. The AF areas are shown in the bright and very large optical viewfinder, which also shows 100% of the final image. In addition, the camera offers a live preview on its very large LCD screen (8 cm/3.2 in) that has a very high resolution (1.229 million RGB dots). The LCD screen is fixed, which is a small drawback when using the Nikon D7100 as a high-end video camcorder. It is able to record Full HD videos with up to 60 frames per second (interlaced) or up to 30 full frames per second (progressive recording). Manual exposure settings can be used when using the camera as a professional recording tool.
The Nikon offers parallel recording of Raw and JPEG images. In addition, it uses a dual SD card system, which allows for shooting Raw images on the first SD card and the JPEG version of the image on the second card. The two cards can also be used in serial mode (recording on the second card starts when the first card is full) or as a back-up system (to copy images on the first card directly to the second card).
The camera offers scene modes for beginners. Professional photographers can use manual exposure modes like S, A and M.
+ Extremely high image resolution and image sharpness
+ Very fast SLR system
+ Massive and robust body, carefully sealed
+ Easy handling, automatic functions for beginners (scene modes, for example), but also a lot of individual settings for precise set-up of all parameters
+ High-end video features (including manual set-up, high frame and high bit rates)
+ Large LCD screen
+ Large optical viewfinder (shows 100% of the final image)
– No swivel monitor (would be nice to have, especially for recording video sequences
– GPS and WLAN function only with additional/optional systems
