Sony 85mm f/2.8 SAM ( SAL-85F28 ) - APS-C Format Review / Lab Test
22 March 2011
Conclusion: The Sony 85mm f/2.8 SAM ( SAL-85F28 ) is an impressive lens when used on APS-C DSLRs - at least with respect to its optical capabilities. The lens is extremely sharp across the frame from f/2.8 to f/8. Diffraction is a limiting factor beyond. Lateral CAs are quite low which adds to the subjective quality perception. The lens produces only a very slight amount of pincushion distortion.
Summary: The Sony 85 mm 2.8 is a very attractive offer in terms of price/quality ratio. Our Sony 85 mm 2.8 test shows almost only good things: a free lens hood, no distortion, very low chromatic aberration and a high resolution where the corners are little inferior to the center. These are achievements for which you would want to pay much more than the price asked for the Sony 85 mm 2.8.
Pros: Very good optical performances:, High resolution from full aperture, Low chromatic aberration, No distortion, Inexpensive
