Conclusion: If you're a Sony user looking for a solid and simple-to-use standard zoom, this is a great deal for you. We don't consider the Â£559 price-tag to be too steep for a lens of this quality, especially as it is extremely well-built and tough as old boots.
Summary: The Sony 16-50 mm has proved to be a very good lens in this test, in combination with the Sony A77 . The Sony 16-50 produces very sharp images. The resolution is sometimes behind the extremely high resolution in the center in the corners.
Pros: Good optical performances: resolution, distortion and chromatic aberration, Decently built
Cons: sensitive to ghosting, lvignetting at 2.8 could be corrected better
