I researched and found both 70 to 200 lenses, and at first I bought the other one. But I regretted it, I really wanted the macro more than the extra speed. I returned it, and I am very glad, the other lens was faster yes, but quite a lot bigger and no macro. And the camera has eight stops of image stabilization, and noise reduction on the computer is magical. So I’m satisfied with the speed of this lens as well. I hope it’s ok to leave this with no photographs, I am learning to use this by getting birds in focus, do you really want to see a goldfinch on my feeder?... Read More  Hide

Haven't had the chance to really use the lens. Just came back from brazil but did not taker this lens. Biggest drawback is the weight.

Hard to focus in low light is probable more of a problem with my Sony a7. Even when using my BIG Sony flash, its hard to focus in low light because there is no IR Preflash focus assist

This lens is awesome when it's on .... but do to some focus haunting and slow focus I had to knock it down a star
