I bought this lens for use with an A6000. It is used alongside an 18-105 OSS G, which I can compare it with. They are used mainly for nature and sports. The 18-105 takes great photos, is very light and portable and has a constant 4.0 aperture, and a constant length (size); However, I find it is not...

I got this lens to complement my SONY16-50MM f/2.8 on my A77M2. I mainly use it for nature photography. The construction is a perfect balance of weather-sealed solid construction without being too heavy to carry along on hikes. (Of course f/2.8 would be better, but imagine the weight!

The 70-300mm G lens is a beautiful zoom. Pictures are sharp as a tack across the focal length and aperture. I use it both on mt a77 and a850 with wonderful results. The only draw back is the weight, it's pretty heavy.

Rugged design; fast focus; superior image quality

Heavy

I bought this lens earlier in the year and have been using it consistently since for wildlife and bird shooting. It doesn't do great in really low light but with the correct ISO in lower light it's fine. The focus is decently fast and the bokeh is nice.

Beyond question this is a seriously good lens - at the price it needs to be. It is the kind of lens you use with a camera on the back, rather than use the camera with a lens on the front!

Easily Interchangeable; Strong Construction

Barrel rotation on zoom; Expensive; Heavy; No tripod bush; Zoom lock only at 70mm - no intermediate stops

Good image captures with Sony A77. Good quality-price ratio.

A handy lens to have in the bag if you are on a budget. Images are for the most part clear and sharp until you get to the big end. Sharpness drops away quite a bit at 300mm. Macro performance is surprisingly good for a 1:2 zoom lens. Quite a decent lens for the money.

Easy to use

Build quality

for video camera only not for still

Well made lens constrained by its slow speed. Reasonably sharp and compares well to the other manufacturers. The fly by wire focus is ok but not as good as manual direct focus. However the auto focus is excellent if you're likely to use that (on my A7R2). I have confidence in this lens.

"Af first, I thought, it would look ridiculous on my small Sony a600. But I tried it on, nevertheless. It turned out not to be that ridiculous after all. It was a bit heavy, but not too heavy. It was ok to handle, could zoom in and out with ease.
