The size of your sensor will affect your images – here’s how…
01 FX or DX?
Nikon SLRs feature two sizes of sensor, FX full frame) and DX (crop, or APS-C). The FX sensor is essentially the same size as a shot taken on 35mm film, and is mainly fitted to professional models. The DX sensor is 15.8x23.6mm, and features on most of the more affordable Nikons.
02 See the difference
This size difference has several effects, but the main one is to do with how much of a scene you can include with a particular focal length lens, known as the field of view. Using the same focal length lens, the FX sensor will give you a wider field of view than the DX one.
03 Mix and match
This effect is known as the ‘crop factor’. In the case of DX cameras the crop factor is 1.5x, so you have to multiply the focal length of an FX lens by 1.5 to get its effective focal length when used on a DX camera. An FX camera will go into crop mode when a DX lens is fitted to it.
