Sony 50mm f/1.8 DT ( SAL-50F18 ) on Sony NEX - Lab Test / Review
23 September 2010
Conclusion: Optically speaking, the Sony 50mm f/1.8 DT ( SAL-50F18 ) is a good performer on the Sony NEX. The lens is sharp even at f/1.8 and it reaches more than very good results across the image frame around f/5.6. Lateral CAs are absolutely negligible which adds to the high sharpness perception. The lens produces some slight amount of barrel distortion but it's not really field-relevant. Typical for a dedicated APS-C format lens it shows rather significant vignetting at f/1.8.
