|comment:||The high probability of finding a non-AF copy of this lens has driven its price way below what it should be worth. Consider its specs on paper: this is a lens in the same weight / size class as the Beercan, is 1 - 1/4th of a stop faster at all focal lengths, and costs on average 1/3 as much. In my opinion, the existence of this lens and the Minolta 70-210mm f3.5-4.5 completely negates the value of the Beercan. While the Minolta 70-210mm f3.5-4.5 is both light and sharp, this Sigma is heavier but provides good low light coverage.|
If you're hunting for an AF copy of this lens, consider asking the seller the following questions: what is its serial number, and what camera body was it used with? If the lens has a serial number beginning with a 2 and/or was used with the 3000i/5000i/7000i/9000i series of bodies, then you very likely have a winner.
There are nonetheless, quite a few negatives to consider: the lens is both slowest and softest at 200mm. The giant front focusing element has a lot of mass and extension, so both AF speed and accuracy can be compromised. Hoods are thread on only, and you will NEED a hood if you want to shoot in the sunlight.
Overall, don't get this lens unless you need low-light coverage.
I briefly tested this lens on an SLT-A65. I can confirm that AF works correctly (and speedily, much better vs my A200), but I cannot say whether or not the aperture mechanism works correctly on the SLTs. I have also tested it on an NEX-5n via the LA-EA1, and in that combo the aperture does work properly.
