Nikon D7100 review – Filter-free imaging sensor
While Nikon’s D5200 and D3200 also use a 24.1-million-pixel sensor, the absence of an anti-aliasing filter in the D7100 should mean that images from this camera will be sharper. I was intrigued to see just how much of a difference the removal of the filter makes, so I have recorded the same scene using the D7100 and D3200 to find out. Each camera is set to the same exposure settings and uses the same 17-55mm f/2.8 DX lens.
When the two like-for-like images are viewed at 100%, there is a difference in fine detail. The D7100 is able to reproduce that little bit extra, with edges showing greater contrast and clarity. Display the images at 50% size and it is more difficult to tell them apart. So, those who are looking to use a camera to its full potential, such as landscape photographers making prints of A2 or larger, are better served by the D7100. However, for anyone who rarely views prints larger than A3 and who shoots general day-to-day images, the D7100’s extra resolving power probably won’t be required.
Image: Detail is so sharp in images from the D7100 that it is largely unnecessary to apply sharpening post-capture, unlike those from the D3200
