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...

I bought the lens for yourself. The lens is in exсellent condition. Auto focus works flawlessly. Pictures in the "macro" get great. I tried to do the usual shooting, the result was normal, but such surveys would recommend using a long-focus lenses and do not forget that lens is "macro".

This is the single most valuable lens I own! Bar None! "I started drooling over bigger and faster zooms" But……… The Sigma 50mm f2.8 Macro lens will make you a better photographer if you will let it.

Great lens! I use this on my Pentax K-50. It's not a 50mm as the review headline says though while writing this, it's a 70mm. It takes wonderful macro images and I use it quite frequently for that. My images can be seen here: alittleplaceontheweb.com if you would like to see examples.

I use this lens mainly for portraits and for macro photograpy. I always achieve perfect focus on both manual and auto. So far ,I have discovered no cons to this lens. Superb.

Lightweight; Strong Construction

Real pleasure to use.. I found the photos sharp... When using macro it's better to use manual focus, so can't comment on the af motor... Would also recommend a tripod as even the slightest movement and your in trouble... If you want it cause you want a 50mm lens then go for canon ...

Macro; Well made - solid

Price

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

Yes, I would recommend this to a friend

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

Poor in Low Light

a worthy upgrade for your kit lens. It offers top-shelf performance, speed, construction and ergonomics for mid-range price. Makes you wonder why the other stuff costs so much!

Speed; SUPERB CONSTRUCTION!; ergonomics; value; performance

noisy focus; slower focus than Nikons; 67mm filters
