The DG moniker indicates that this is a full-frame compatible lens, while EX indicates that it is one of Sigma's top marque lenses. The lens has an impressive maximum aperture of f/2.8, dropping to f/45 minimum (f/32 on Nikon or Pentax cameras).

Well priced and sturdy enough lens; full-frame imaging circle

Image quality is not as good as some others

Sigma's 50mm f/2.8 EX DG has the shortest focal length and lowest price of the four macro lenses in the company's current line-up. Designed for use with full frame digital SLR cameras, it can also be fitted to DSLRs with smaller APS-C size sensors, where it covers a similar field of view to a 75mm...

Yes, I would recommend this to a friend

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Lightweight

Poor in Low Light

This a sharp lens. I use this lens quite a bit and I am happy with the performance that it provides. There seems to be equal sharpness across the frame, and this is certainly a good thing. There are a few cons, though. I have noticed is a bit of blue fringing under certain light conditions.

This is an absolutely stunner of a lens, the image quality is superb and pin sharp, the focal range allows fantastic bokeh especially for portraits and macro photography, if your looking for a good portrait lens and dont want to pay a fortune then your search stops here, check out some pictures om...

The first thing I noticed is the ultrafast autofocus. The pictures come out extremely sharp, the colours and contrasts are amazing. I took a few pictures at f32 and the depth of field you get is just incredible, as sharp as can be from the most close object to infinity.

F32! Incredible depth of field! Nice coating on the lens; perfect colours and contrast

None so far :o

Sigma lenses are truly an inexpensive alternative to Canon or other brands higher priced models. The lens is amazingly powerful and precise for only a few hundred bucks. I know that I've wanted a macro lens for a long time but didn't think I could afford one.
