While it does not focus well in really low light, few lenses do. The sharpness and focus speed are very good. The weight is great for hand holding, stabilization works very well it feels really good on the a6000. My Nikon system cameras and lenses are way heavier and no better quality.

This lens really surpassed my expectations. I was skeptical on buying it at first. I was more curious about how I would be able to use a telephoto lens in the shooting environment that I work in and it was more of a challenge to find a way to mix it in my bag. However, after shooting with it for the first time, I was shocked and it had my attention in a great way. Everything is an extreme close-up with this baby compared to my GM 24 - 105m f4 OSS and my Zeiss 16 - 35m f4 OSS which is actually a very intimate perspective on subjects being photographed. The clarity/sharpness of this lens makes that perspective truly remarkable and I don't see how spending over a $1000 more for the f2.8 could be justified. I highly recommend this lens and challenge you to see how you can put it to use in your bag!

Even with an "old" a6000 body this lens is what I needed and desired. I primarily shoot outdoors so the f4 is much better value for my budget. It is great glass that will hold its value as well. It is light and feels great in the hand, and the quick turn zoom is really nice. Macro extension tubes make this really fun around the yard too!

This is very sharp lens with fast and accurate autofocus. The internal zooming makes it a compact combination with an A-series body. It is reasonably light and well balanced.

I bought this lens to replace the 55-210mm kit lens I had for my Sony a6500 mirrorless camera. Let me say, I am BLOWN AWAY by the sharpness of this lens and how solid it feels. While it does have some weight to it, the constant f/4 aperture is truly amazing. I take lots of photos in a dimly lit hockey rink and compared to the kit lens, this guy does an amazing job. Very pleased with my purchase. Some example shots are attached. Both photos were shot at 1/800 shutter, f/4 aperture, 3200 ISO on a Sony A6500 at roughly 120mm focal length.
