sigma

After much research (and some opinions on here) I bought a Sigma 70-200mm f2.8 lens for my Canon t3. The auto focus is off. I was reading on how to calibrate lenses to cameras with things like the Focus Pyramid, but I can't seem to find the option to calibrate in this camera. Am I missing...

Hi guys, This is my first thread in a discussion section so if there is anything I did that's against the rules, just let me know and I will edit it immediately! I had been having focus problems on my Nikon 50mm f1.8g. Plus, I recently purchased a Sigma 17-50mm f2.8 which (based on what I...

I currently own the 24-105 f4L, the nifty fifty, and the 135mm f2L. I really can't decide between the Sigma 35mm 1.4, Canon 85mm 1.8 or the 70-200mm f4.

I bought this brand new lens two years ago and have been using it since then. The lens is in great condition - no scratch or dust. All accessories are included - lens cap, case, and the original box. S35 is considered the best 35mm lens for full frame cameras. It beats Canon 35L on sharpness and...
