|dCap#366 date: Dec-29-2005|
flare control: 5
|ownership:||I used to own this lens|
|compared to:||Canon 200/2.8 L II USM, Minolta 200/2.8 APO G, Minolta 100-300/4.5-5.6 APO (D), Minolta 300/2.8 APO G|
|positive:||improves with the 1.4x EX converter. Build quality is brilliant. Case and tripod collar too. Well done Sigma. Good hood too.|
|negative:||soft at 2.8-4 at the 200mm ens, hunt in all but brilliant light, only f5.6 and beyond are useable|
|comment:||Its big and heavy, but that's part of the deal with a 70-200/2.8, be prepared for this.|
Mine was frankly rubbish. I couldn't even get a sharp image out of it at f5.6 on the 200mm end. I figured if I have to shoot at f8 why not get the 100-300/4.5-5.6 and shoot that at f8. So I did, and the 100-300 was MUCH sharper
I bought this with the intention of using it at f2.8 or f4 at the 200mm end. I kept using it for about 3-4 months before I gave up. f5.6 was almost sharp. a 200/8 is just plane stupid for this money. The 200/2.8 prime is cheaper used than this is new, and I eventually went that way. The 200/2.8 prime is razor sharp and usable at f2.8. The 70-200 EX isn't.
Good lens if you shoot in very bright light or only in the summer. Useless for wildlife which is a real shame. A 200 (300 on digital) is a good length for wildlife, shame this lens lets it down.
Bokeh was also pretty horrible on in-the-field nature shots.
