Originally posted by Alfie1965 I have the #7 on your list and I have to say I am happy with it, I got it as a replacement for my FA 80-320, which I managed to drop in soft sand on the beach last year. It compares very well to the FA. Though the colour definition was slightly better on the FA, the sigma is generally a better all round lens and the 1.25 Macro at 200-300mm is a big plus.
My internet is down at home so I am posting from work and I don't have many photos on my computer here, I have posted one taken with the lens at 300mm 1/350 @ F5.6 in my gallery photos Tigers at Flamingoland. I took this through glass, and the camera was hand held, only a snap shot but it shows the lenses capability quite well.
Thanks, it being capable of a quicker shot like that is certainly a plus!
I'm leaning towards #7 personally. My w-2s can't come soon enough!
