comment:I first purchased a clean copy with original retail packaging from another Dyxum user. I purchased a second similar copy Buy-It-Now for $356 from a Japanese eBay company. These are somewhat rare in the used market though there are generally several used copies available for around $500 from Japan. Sigma replaced this lens in 2012 with a much larger, optically stabilized zoom that supposedly had much better image quality but was never available in A-mount. "LENS MADE IN JAPAN"

This lens has internal focus and internal zoom. Neither the front nor the rear lens element moves at all. The HSM focusing is fairly quiet and fast.

I was hoping this lens would be a good match for the Sony DT 16-50mm F2.8 SSM, but it looks like Sigma hadn't figured out image quality by 2008. This lens performs similar to the older, larger 70-200mm EX DG APO. Both have decent center sharpness, though perhaps not by autofocus. The first copy has some issues which really show in the top right corner. The second copy is much more consistent across the frame. The Minolta zooms have much flatter focus planes. The field curvature is even a bit worse than the Sony DT 55-200mm F4-5.6 SAM.

The first copy worked pretty well for tracking moving cars with the A68, and the image quality was acceptable at F2.8. The axial CA seems to be better controlled than the Minolta lenses. I feel like this lens is a bit overrated, but it is a decent enough compromise.
