Manufacturer description

The advent of digital SLRs requires optimum lens performance and therefore the very latest optical technology has been incorporated in the production of the new Macro 50mm f/2.8 EX DG. This ideal standard lens sets the benchmark for digital SLR cameras.

The new advanced lens design corrects various aberrations. This macro lens is specially coated to get the best color balance while cutting down ghost caused by reflections from the digital image sensor. This lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.

A Floating Focusing system that enables this lens to photograph objects precisely in entire focusing range.

This lens has a minimum aperture of f/45 (for Sigma, Canon and Konica Minolta mounts) or f/32 (for Nikon and Pentax mounts) provides greater depth of field.

A screw-in hood is included, for convenient use of circular polarizing filters.

From the editor

The updated version of the Sigma 50mm F/2.8 EX Macro lens (1998) optimized for use with digital SLR cameras. In other respects the lens does not differ from the predecessor.

Notes

The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3500, D5000-D5600 digital SLR cameras.
