Best lenses for the 24M-Pix Sony SLT-A77: Primes and ZoomsBy Kevin Carter - Friday November 15 2013 Lens Recommendations
Full-frame models continue to dominate our rankings for image quality, but they have price tickets to match. Sony’s Zeiss branded 24-70mm f2.8 and 16-35mm f2.8 ZA models perform well, as you might expect from modern designs of this pedigree but there are some more accessibly priced third-party offerings that perform very well.
The Tamron SP AF 28-75mm f2.8 achieves a good DxOMark score of 16 points and at just $499 is in ranked second in this category. Surprisingly, the newer full-frame Tamron 24-70mm f2.8 doesn’t perform as well as the earlier iteration. At any given aperture or focal length it’s simply not as sharp or as homogenous across the field.
In fourth place the Sigma 17-50mm f2.8 (26-77mm equivalent) has a good overall DxOMark score and is well corrected but it has slightly disappointing sharpness – the lowest measured of this group. If lens speed isn’t critical, the APS-C format Sony Zeiss DT 16-80mm f3.5-4.5 offers good all-round image quality and a versatile range but that comes at a price.
