Summary: Pros: The lens focuses quickly, it is quiet and feels solid. Cons: After using it for a few days the lens does not seem to fit snugly on the camera body anymore. I have noticed that it suddenly just won't focus and I have to off/on my camera.
Signma 120-400mm with Pentax K3 moving subject focusing

Summary: It's a heavy lens. Not so much that I worry about it. But for extended use you would want a monopod at least if using higher magnifications. I have been testing with the continuous focus with Pentax K3 and it works well. Focus is nearly silent and pretty quick.
Great for a day light shooting and still photography

Summary: Great for still shots in daylight shooting, However I purchase this lens to shoot night time football action where the lighting in high school sports aren't that great. the f/4-56 just doesn't let enough light in.
Summary: I have been looking for a lense for about a year and finally decided to get this. I have a Nikon D80 and this works very well with it. Pictures are fabulous, but at 400 it does have a hard time focusing and the lens is pretty heavy. Don't expect to carry this around for sightseeing
Great telephoto Lense for wildlife, but a bit soft

Summary: I originally purchase this lense for my African Safari trip in early 2012. I used it with my Canon Rebel T3i or 600D together with 3rd party battery grip. I've now used it multiple times at Africa, Montana and Galapagos. The zoom was sufficient and the lense is sufficiently fast.
Summary: I have owned the Canon 100-400L and though I know it intimately from shooting many images through it and having to do field repairs, I just never fell in love with it. I think for me the push-pull zoom was just too awkward. Others love it, not me.
