What is the sigma 105mm f 2 8 dg dn macro art good for?

The Sigma 105mm f/2.8 DG DN Macro Art is a macro lens first. It's built for full-frame cameras and comes in Sony E and L-Mount versions. It's autofocus, but it isn't stabilised, so for handheld close-up work you'll want a steady hand or a fast shutter speed.

On full frame it frames at 105mm. On APS-C it behaves like about 158mm, which gives you more reach for small subjects from a distance, though the f/2.8 gives the depth of field of about f/4.2 there. If you're shooting on an APS-C body, the focal length converter explains the depth-of-field maths. The lens fits a long list of Sony E bodies and L-Mount cameras, so check your model on its page before you buy.
