Very hard to correct chromatic aberrations, strange colors. Sharp. Tried on Canon 80d and returned after a couple of days. ( real estate photographer)

The lens is very sturdy and the image is great in day light. The images are very sharp but its not that great for night photography. If you are looking to buy this lens, I suggest you check out the real item or silmilar items because 8-16mm is really wide.

SUPER and I mean SUPER wide

Wight; Not great for night photography

Owning a Olympus E5 I have always wanted the Zuiko 7-14mm but the price was just to high. I have recently moved to Sony and picked up this lens for less than half the cost of the 7-14mm. With the crop factor it is actually 2mm wider than the Zuiko. The Sigma is a well made lens.

good lens, excellent results.

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

Never bought a Sigma before, and I had read that some of their wide-angle lenses felt a bit cheap. Pleased to say the 8-16mm looks and feels like the reasonably premium lens that it is. Nice and weighty, smooth focus and zoom rings, and a very snug fit to my A700 a-mount.All lenses are compromises.

Sharp Focus; Strong Construction

Slow Focus

I was lacking a really short lens for Landscape ..... fisheyes don't hold it for me but a really short,sharp lens with good control of barreling does. This is probably the only lens out there that has all the above features in spades .....

Fabulous. It's like having a full frame camera now. If you shoot landscapes or architecture this lens is a must.

This is a great lens and exceeded my expectations. It is V E R Y wide!

Durable; Easily Interchangeable; Fast / accurate auto-focus; Strong Construction

This lens did give me good, sharp images- once I figured it out. I bought this primarily for real estate interiors and urbex photography. One of the very first things I noticed about this lens, was it gave dark images.
