24 MP without AA filter in a semi-professional body: D7100 diagnostics

Nikon D7100 (2013) brought a 24.1-megapixel sensor without an optical AA filter to the class of semi-professional DSLRs - the same matrix that was used in much more expensive professional cameras. The sharpest image possible without anti-aliasing, plus a 51-point AF system and water-resistant body, made the D7100 the choice of serious photographers who wanted professional results without a professional price tag. Intensive commercial use is a typical story for a used D7100.

The absence of an AA filter increases the requirements for the state of the shutter: at 24 megapixels without anti-aliasing, any drop in sharpness from worn-out mechanics is more clearly visible. Checking the mileage when purchasing a D7100 is mandatory - precisely to make sure that you get the full stated potential of the camera.

Shutter life 150,000 and real operation

The D7100 shutter is designed for 150,000 guaranteed operations. A camera with a mileage of up to 60 thousand is an excellent purchase with a large resource reserve. Over 120 thousand - monitor the accuracy of the exposure and possible signs of wear on the curtains.
