Earlier today, Nikon announced the Nikon D7100 digital SLR camera, a successor to the hugely popular Nikon D7000. The new model inherits the D7000’s viewfinder, shutter assebly, 2016-pixel RGB metering sensor, dual SD memory card slots, weatherproof body, EN-EL15 battery and core functionality; and adds a new 24-megapixel sensor with no low-pass filter, an Advanced Multi-CAM 3500DX auto focus module with 51 focus points, a new LCD screen and a number of new features including a “1.3x crop mode.” Note that as the Nikon D7100 is a DX camera with a “crop factor” of 1.5, the “1.3x” mode is in fact a 2x crop mode relative to 35mm full frame, essentially turning the Nikon D7100 into a 15-megapixel FourThirds camera while retaining the 3:2 aspect ratio and allowing for a slightly faster continuous shooting speed.

In order to help you get a clearer picture of how they compare to each other specifications-wise,  we have compiled a handy little table summarising the key differences between the two models, based on information available to us at the time of writing.

Do note that the table highlights the key differences only - there are a few interface changes as well, such as the addition of a customisable “i” button and the swapping of the Zoom In and Zoom Out buttons. The D7000’s Live View lever has given way to a button encircled by a switch that toggles between Photo Live View and Movie Live View modes, while the red movie record button has been moved to the camera’s top plate, close to the shutter release - but overall, the Nikon D7100’s user interface has remained remarkably similar to that of its predecessor.

Naturally, we will be delivering you a fully fledged in-depth D7100 test as soon as review units become available.
