How many macro lenses does one lens manufacturer need?

Nikon F mount
This is the lens mount used by Nikon DSLRs. However, because Nikon makes both full frame and APS-C format DSLRs, lenses for this mount come in two types. 'FX' format lenses are designed for full frame cameras, while 'DX' lenses are designed to cover only the smaller APS-C format. These are the two terms used by Nikon, but third-party lens makers may just refer to them as 'full frame' and 'APS-C' or 'crop' sensors.
You can use FX full frame Nikon F mount lenses on the smaller APS-C Nikon DSLRs (there's a crop factor of 1.5x for working out the effective focal length). You can also use DX APS-C lenses on full frame Nikons, but because these lenses cover a smaller area, the camera will switch to it's 'DX Crop' mode, so it will only use a smaller area of the sensor and you won't get its full resolution.
