A Fantastic Wide Prime Lens
My sample version has no front focusing as reported on some websites. I
have no reservations in recommending this lens to professionals or analytical amateurs who
require a super fast low-light wide-angle lens.
I have used this lens for critical
wedding photography and other
challenging situations. It also has provided me a vast amount of images of my family
from around the house.
This lens, like the Nikkor 50mm f1.8, is a lens that I would not consider giving up. (I have photographed with the Sigma 28mm f/1.8 and the Nikkor 50mm f/1.8 side by side and apart from the angle of view, I cannot tell any dissimilarity between the two.) This lens is hard to ignore as it provides so much for the price that it is hard to ignore. And for those snobs that consider Sigma an inferior brand, you just don't know what you're missing.
