"only" f2.8
comment:A nice small pancake lens for APS-C E-mount bodies, giving a 30mm field of view, which for me is close enough to a 28mm f2.8.
The centre resolution is very good from maximum aperture, the outer field a little softer, but not much. Stopping down to f5.6, resolution across the frame becomes more even, although it is never exceptionally "sharp" looking. It's benefits are it's size and it's generally very even performance - the outer field even at maximum aperture is better than most zooms.
If you compare it's performance in bench tests to the Minolta/Sony 20mm f2.8 when used on APS-C, the older lens appears to have slightly better centre performance, but even on APS-C the outer field is weaker. In comparison, the new E mount 20mm f2.8 looks good for it's modest size, and although the material value for such a small lens doesn't seem great, it's still half the price of the A mount lens.
The only major negative is the lack of OSS, which is a pity.
