ownership:I own this lens
compared to:Sony 75-300, Sony 70-300.
price paid:$389
positive:Great general use tele-zoom lens.
IQ seems much better than the Sony 75-300 kit lens.
The USD is fairly quiet.
Pretty much 90% of the performance of the Sony G for less than half the price.
Works on FF and APS-C sensors.
negative:Lack of focus limit switch and small variable aperture makes it less than ideal for sports/action in other than ideal daylight conditions.


comment:Got this lens to use for a bit more reach for personal work when I go out and don't want to pack the 70-200G. Very pleased with the IQ but the focus is much too slow to use reliably for action shots. I test new stuff using my two favorite action models, Sydney and Cooper. My dogs. We let them run around the yard chasing a Frisbee and each other. With the camera set to release priority we took Over 300 shots. About 50% were OOF and a number more soft. With the camera set to focus priority on C mode the lens hunted and failed to focus lock quite a bit. Keeper rate went up to about 60% with some others on the margin of being soft. But this is an extreme test. The dogs are running around a big yard in an unpredictable manner. Much harder to focus on them than even a HS football player running with the ball. This isn't bad but not near the keeper rate for the lenses with a focus limiter. I would definitely recommend this lens if you are on a budget and want good general daylight images with decent bokeh.
