Sigma 75-200 f/2.8-3.5
canon 55-250 IS Mark 1
|price paid:||60 used|
not as sharp as it's siblings
|comment:||I paid very very little for this lens in mint condition (from an online retailer, I think it was a pricing error). Came with tripod collard, but no hood, picked up a rubber hood for 5 bucks and I'm good to go. Mine is a vivitar series 1 version, but it's the exact same lens.|
I struggled with this lens, it just wasn't sharp, I figured with all these telephotos I just go at it at full zoom (210mm) and it is a pro lens after all, there's no reason why it's not sharp wide open, at one point I was considering selling it back, because both my beercan and the sigma 70-200 2.8-3.5 was sharper, and this sucka doesn't even get sharp stopped down at 210mm. Then I read a review on here and it said to back the dam thing off 200, well I backed it off and test it, and low and behold, it's sharp at around 180-190 wide open, at full zoom it's just a mess. So I've decided to keep it, 180-190 2.8 for 60 bucks works for me.
There's a teeny tiny bit of CA. The color is a little strong on yellow and doesn't pop like Minolta color, it's very typical of sigma of this age, I got a few sigma, I can confirm on this particular topic. Fixable in PP.
The built is good though, all metal and glass, a real tank.
The focus speed isn't gonna win any contest, but it's fast enough and accurate on my A37.
If you find this for cheap, nab it up, other wise go for the more modern 70-200 2.8, those tend to perform better, and focus faster, they usually go for just around 400-600 for tamron/sigma models.
