positive:- Reasonably sharp
- Very small for its range
- Slightly less CA than beercan / 75-300
negative:- Still has CA, especially wide open near 300mm
- Needs stopping down for optimal sharpness on long end
comment:I bought this lens for fairly cheap due to the fact it was missing its hood and the filter ring was damaged.

Its performance is very similar to the SAL 75-300mm. Wide open near 300mm the 100-300mm APO has less CA than the 75-300mm, but it also seems like it's slightly softer, so it's mostly a wash. Stopping down is required for optimal performance near 300mm.

I'm a little disappointed in this lens as reviews implied it would be better than the 75-300mm. In practice there's not a lot of difference in IQ, and you're mostly just getting a smaller lens in exchange for 25mm less on the wide end.

If you aren't concerned about size, I'd go with the 75-300mm, which is wider, performs similarly, and is much cheaper. On the other hand, this lens is a good bit smaller, so it makes a great travel zoom when you don't have room to spare.

The "D" variant of this lens appears to be optically identical, so I'd probably stick with this non-D version (which is much cheaper). ADI for this sort of lens is definitely not worth a 50% premium.
