Sigma 50-500mm F4.5-6.3 DG OS HSM User Reviews

Recently I received the new Sigma 50-500 f4.5-6.3 APO DG OS HSM. Nice! Focusing seems to be accurate, and very silent. Optical stabilization works well. The lens feels good hand held on my Sony a700. Built like a tank! Have not had a chance to do much testing due to inclement weather here in Western NY. Just took some low light test shots inside, absolutely love the bokeh! Now all I hope for is an upcoming replacement for my a700!!! Further testing has shown that this lens is very sharp in ...

I shoot action sports subjects, including surfing, yachting, motorcycle and auto racing. With all these sports, the action moves from close-up to far away very quickly, too quickly to switch lenses, and often too quickly to switch to another camera and lens. So I need a lens with a very broad range, which makes the Sigma 50-500mm the perfect lens for my work. I shoot with Sigma cameras, which are limited to Sigma lenses. But even if I shot with Nikon or Canon, I'd still use a Sigma 50-500mm ...

Been shoot with this lens for almost 2 years now. Love it. It's equivalent to an 80-800mm on my Rebel. I found it great for dog shows, the dog park, and anywhere there's good light. I even did a video review on this lens at youtube. . It is heavy though. It weights 4.4lbs but the benefit of the images outweigh the weight of this lens for me. Oh yeah! a decent 500mm lens under $2k?

Bought this lens from dpreview birder who'd sent it to Sigma to, for $300, have focusing brought up to Canikon standards, and, now 88 year old was finding it too much. It is a hand -arm!-ful! The Sandhill Cranes which tend to be my only sustained bird-shooting have been late, so I've been shooting other things, to be pleasantly surprised to find that my particular copy is also a terrific lens with great colour and good bokay. Just took the first Cranes-in-flight shots, and will be processing ...

Camera: Canon 60D Pro: * Amazing hand-held optical stabilization. * Very sharp throughout range, only marginally trailing off in last 50-75mm. * Fast autofocus with surprisingly little hunting considering the length of the lens. * Beautiful smooth bokeh (my preference, others prefer sharp/patterned). Cons: * Weight. * OS is a little slow (0.5-1 second for it to have full effect), but worth the wait. * Large. Takes up 3-4 lens slots in my camera bag. Upgrading from the kit 55-250 lens, I was ...

I have had the lens for a few months so far and it is probably the best Telephoto lens I have owned and I have owned quite a few.  It has become my everyday lens.. I know it's heavy but what can I say, I just love it. From 50mm to about 425mm it's very clear and a little soft the rest of the way. It has a very Fast focus speed on my Pentax K-5 and my K-30. Not the best on my K-01 but that camera isn't built for such a large lens. The Boken is very good at all focal lengths in my opinion. I ...
