Hi guys, I'm caught in another dilemma again, hope I can get some opinions. I was pretty much decided on the 55-250mm IS, but just today I bought a 70-300 Sigma on my friend's behalf and found it pretty nice too.
So, as you might have expected, I started weighing the pros and cons and found very little differences that I currently know, hoping someone could come by and push me off the fence.
55-250mm - IS, better CA control, (1:3 magnification), bit lighter (150g or so)
70-300mm - Longer, better build, 1:2 marco, cheaper by $100-140(?), comes with hood ($).
AF on the Sigma seems really sharp, however I haven't tried the Canon, so I can't say.
I was under the impression that this should be a daylight lens, IS should be a non-issue at around 200-400 ISO. The things I wanna take should also be living things, so, do I really need the IS? I can't seem to convince myself.
Reviews seem to stand in favor of the 55-250mm, but I really don't see why is there such a big difference.
Thanks for reading! Please comment if you own either of the lenses.
