Sony FE 28-70mm F3.5-5.6 OSS: Serious contender to the Zeiss?By Kevin Carter - Tuesday April 22 2014 Lens Review
At less than half the price of the marginally wider, slightly faster Zeiss 24-70mm f4, this in-house Sony model looks like a tempting alternative, but can it meet the demands of the high-resolution sensor in the A7R? Read on to find out.
Although overshadowed by its more pricey, and glamorous sibling, the Zeiss 24-70mm f4 OSS, this also stabilized 28-70mm f3.5-5.6 OSS model looks like an attractive option. It’s not quite so wide of course and it’s 1 stop slower at the longer end but it’s 1/3 stop faster at the wide end and it its just $499, instead of $1,199 for the Zeiss. It has a total of 9 elements in 8 groups with one low-dispersion element and three with aspherical surfaces to reduce chromatic aberration and distortion. Also, it has dust and moisture sealing and a seven-bladed circular diaphragm for improved rendition of specular highlights and smoother transitions to out-of-focus areas. It weighs 10.41 oz (295 g) adopts a 55mm filter thread, and measures 2.85 x 3.27" (72.5 x 83mm) and is available now.
