I was looking to close a "focal length gap" for the Sony A57 a fast lens with a fast, quiet autofocus. About an Amazon-dealer I ordered the Kit_Objektiv the A77, Sony SAL1650 16-50 wide-angle zoom lens mm F2.8 SSM and realized very quickly after my standard tests that this objective has not met my expectations. The lens blurred recorded in almost all sectors. Two points, however, for the fast delivery and the unerring, quiet and very fast SSM autofocus. The objective was therefore sent back to Amazon. The information published on Amazon mostly positive assessments evaluated this lens caused me to purchase another try in photo departments of relevant markets. The test of a SAL1650 on a A77 brought in the department even worse results. The knowledgeable salesperson had to admit that the test pictures of my "soup zoom" SAL 18-250 to lengths were better. A checked in another Specialists lens brought then but "surprisingly" quite positive results. More extensive testing after purchase could attest to that. The lens Sony SAL1650 16-50 wide-angle zoom lens mm F2.8 SSM filled to under this focal length range objectively tory expectations. With in-camera lens correction and in the 16: 9 view blur areas, vignetting and CA's were negligible. Obviously larger Serienstreungen be expected in this type of lens made in China and it is recommended in any case, a test in the photo shop with your own camera body.
