Sigma DG 105mm f/2.8 EX OS HSM Macro

Sharp images The image stabilization makes a little bit of noise, but nothing bothersome. Lens is incredibly sharp and pairs well with the Sigma 1.4x extender when you need the extra reach. Haven't had any problems with it at all. Can't really comment on the autofocus since I use this primarily for macro video work which is all focused manually. It's solidly built, my only complaint is the lack of manual control for aperture, but that seems to be pretty common with third-party Canon mount lenses and I knew that going in, so I really can't deduct for it. Buy with confidence!

A very good 3rd party budget lens that can do a very reasonable job. Had tried out this lens with a Canon 6D and a Canon 7D MII for about a month and am very happy with it for the price. All the lens functions (e.g., OS, AF) work well with both cameras. The images were all very sharp when used as a prime lens. However, when using it as a close-up macro, some images were out of focus or fuzz. Don't know if it was the OS or the AF issue. But, for less than $700, this lens works really well!

Excellent 105mm Macro Lens The lens renders very sharp macro images without trying to get a couple inches from your subject like you would with a 50mm macro lens. The auto focus works well and quickly, but I tend to use manual focus for most macro photography. The manual focus is smooth and precise. All in all, an excellent macro lens and a great buy.
