Compact macro prime lens for Nikon F-mount cameras.
The Sigma 50mm f/2.8 EX DG Macro is a 1:1 macro lens for Nikon full-frame cameras, D-type indicating distance information transmission. The 50mm focal length provides a standard working distance at 1:1 macro — practical for small-subject photography where the lens-to-subject distance needs to be short.
50mm focal length, f/2.8 maximum aperture, 1:1 macro capability, DG (full-frame), D-type CPU, Nikon F mount.
The 50mm macro at 1:1 provides approximately 20cm working distance — shorter than 100mm macros but sufficient for most small-subject work. The f/2.8 aperture enables subject isolation at standard distances and provides reasonable low-light capability. A practical and affordable macro for Nikon photographers.
Test 1:1 macro accuracy. Inspect for fungus, haze, and coating condition. Confirm Nikon F mount engagement. Test AF at both macro and standard focus distances. Check that D-type CPU registers distance information on compatible Nikon bodies.
