|comment:||I placed an order for this lens with my local shop, but Sony didn't have any in stock. I found a used copy for $155 on Amazon. Then I bought a second copy of this lens without hood for $58. This copy was much sharper wide-open. The previous copy was my first prime lens experience. I've revised my ratings in light of broader comparison. This lens was originally $200 when released in 2010 with a few sales at $175. The retail price increased to $220 in 2012 with sales at $190. Now Sony has stopped offering discounts. "MADE IN CHINA"|
It's field of view is comparably to a 52.5 mm full frame lens, but it does not equal the total light gathering of the old Minolta 50mm f/1.7 on a larger sensor. It is more similar to an old f/2.8 lens in optics size and behavior. It can still produce some lovely smooth background blur. The second copy is much sharper in the center wide-open, but the corners are a bit softer. The first lens had a similar glow wide-open on high contrast edges as the Sigma EX primes.
The minor barrel distortion is a little annoying for raw capture as there is no profile for this lens in the Capture One for Sony conversion software. The zoom lenses have similar amounts of distortion at 35 mm. The Minolta AF 35 F2 is more consistent across the APS-C frame as is the Carl Zeiss 16-80. Neither of those is quite as sharp in the center. The Sony DT 16-50 F2.8 SSM is a little sharper in the center but is worse on the edges.
It can also focus quite closely for semi-macro work. And it works well with extension tubes and teleconverters higher magnification. The focal plane is curved at 1:1 unlike the Macro primes.
The included ALC-SH111 circular hood is smaller than it could be. The much deeper ALC-SH102 hood from the 55-200 lenses fits perfectly on this lens and the 85 f/2.8 SAM and doesn't vignette with either lens on APS-C cameras. The hood bayonet doesn't rotate so an even larger petal hood could be used.
This is very decent, inexpensive prime lens.
