For what you normally shoot, Jan, it very well might. I don't think any of us have had much a chance to try it out against aircraft much, though...

smythie I wasn't even trying More info | Jan 27, 2014 22:59 | #98 Hmm, since I'd either be using it for the odd birding outing or some motorsport, that's sounding pretty average. At least my Sigma locks on pretty well. Oh well, back to trying to find a used Sigma 120-300

. The lens seems incapable of determining whether it is getting more, or less, in focus and will run AF from one end of the range to the other, every time you initiate AF...even if it was only slightly off to begin with. It's moderately infuriating to say the least...I had a flock of Tundra Swans fly across a good 180 degree arc of open sky, about 300ft out and never got anywhere close to focused before they went behind something. That is a LONG time and slow-moving subject to have that bad of a time with.
