The sigma is said to be softer wide open at the long end. What I am trying to figure out is.
How much softer is it... Ie is it unusable at f/2.8 at 200mm or will a little bit of unsharp mask in Post processing fix the problem. On the other hand the Tamron is said to be razor sharp but tends to dip a bit in quality around 135mm. I'm willing to accept slightly softer results at f/2.8 from the Sigma if they can be fixed in post processing but not if it is useless at f/2.8 since opting for the sigma will give me fast/quiet AF and quick shift focusing.. For me this is important because I do quite a lot of theatre work. The tamron is known to be noisier and probably slower on the AF front since it relies on screw drive AF. The perfect solution would be a combo of the Tammy's supposedly superior optics in the sigma body level body.
