Our Review Of The Nikon D7100
The Nikon D7100 is a mid-range DSLR with a crop sensor (DX format) making up its heart. The D7100 is the second in a very interesting line of DSLR camera systems from Nikon. In regards to features and price point the D7xxx series sits right between the upper-entry level D5xxx series and the full-frame D6xx series.
The sensor on the D7100 is a crop one with a crop factor of 1.5x. The camera is built around a 24.1 megapixel DX CMOS sensor. 1.5x crop factor suggests that all full-frame lenses will have a 35mm format equivalent effective focal length of 1.5 times their actual focal length.
The large sensor (23.5 x 15.6mm) is capable of producing JPEGs and RAW frames the size 6000 x 4000 pixels.
The sensor has no optical low pass filter. The absence of an optical low pass filter means the sensor is capable of picking up a greater amount of detail than traditional sensors.
The D7100 comes with Nikon’s EXPEED 3 image processing engine. EXPEED 3 is slightly dated as the latest D7xxx camera already has the EXPEED 4 image processing engine.
Auto-focusing on the D7100 is powered by a 51-point AF system that also has a total of 15 cross type AF points. As we are aware cross-type AF points work better in low contrast and low light situations compared to line sensors.
Native ISO range of the D7100 is 100 – 6400. However, in extended mode it can shoot up to 12800 (H1) and 25600 (H2).
Continuous shooting speed on the D7100 is 6 fps. At that speed it can shoot up to 100 frames. At 6 fps you can expect to get about 1 sharp image of a moving subject every 1 second. This is not the fastest camera around for bird photography, sports or action camera. You will be better off buying one of the pro models in the Nikon lineup for such purposes. Having said that the D7100 can hold its own and is no pushover.
The D7100 is also a decent video shooter. It can shoot full HD videos (1080i) at a maximum frame rate of 60 fps.
Rear LCD Screen
The back of the camera is dominated by a large 3.2” LCD screen. The screen has a resolution of 1229,000 dots. We would have loved to see a tilting / swiveling screen and touchscreen properties. Screen coverage is 100% and diagonal angle of view is 170 ˚.
The D7100 does not come with built-in wireless connectivity. However, you can plug in the WU-1a wireless adapter and the camera will be able to stream images and videos wirelessly to a laptop or wireless storage.
Build Quality and Weather Sealing
The D7100 is a well-built camera. The magnesium alloy chassis of the camera comes with weather resistant properties. Having said that this is not a completely weather sealed body. If you plan to work in inclement weather go for something like the D4S. Then again we are talking about a completely different segment of product.
The D7100 retails at just under $700.
At a shade under $700 the D7100 is a good investment if you are looking for your first DSLR. Migrating from an entry level DSLR? Then there are obviously better choices provided you are ready to cough up the extra money. Even pros looking for a DSLR to take advantage of their long lenses on a crop sensor might be interested in the D7100. Additionally, you get a top LCD panel and twin command dials, features that make the D7100 a semi-pro grade camera.
