Summary: Sharp and light!!! I'm using this on the Sony A7Rii with the LAEA3 adapter and cannot be more pleased. Are there longer Sony lenses with better IQ? No doubt but they will weigh a ton and cost a fortune and honestly the SAL 500mm is geared toward wildlife.
Summary: This is another lens I purchased along with a 30mm macro, and I am very happy with Sony. I been able to zoom in on those elusive Cardinals an blue jays. The image quality is superb. Most definitely recommended to any one wanting to get serious with their camera. Camera used SLT-a57. Just fantastic.
Excerpt: I got the Sony A77II with 16-50 2.8 bundle to get me into the Sony A mount system. I wanted a telephoto zoom, but didn't have much left to spend on one. So I picked up this lens with a rebate that made it about half of what it normally sells for. I'm impressed!
and a Tamron 200-500mm but the 55-300mm is excellent in quality and function

Summary: I currently own the 18-55mm, the 55-200mm, and a Tamron 200-500mm but the 55-300mm is excellent in quality and function. Well packaged and delivered on schedule, the product is perfect for out door life shots without a tripod. I am very pleased with this lens!
