comment:A like new copy with original retail packaging and all accessories. The original list price was $599, but Tamron lowered it to $399 a year ago. The Sony 50 F1.4 has been stuck at $448 during this time, but used copies have been selling for less than $175. I traded my Sony DT 18-135 SAM for the first A-mount copy. Then I bought a Canon EF VC version. "MADE IN JAPAN"

This is a large lens, slightly larger than the Sigma 70mm F2.8 EX Macro. Maybe the size was needed for the optical stabilization system which is not enabled in the the A-mount version. The little Minolta MD 45mm F2 is actually brighter than this lens. This lens is sharper than my copy of the Minolta. The focus plane is much flatter than the Minolta 45, but not as flat as the Minolta/Sony 50mm F1.4. It has worse veiling glare than the 28 F1.8, 35 F1.8, 50 F1.7, and F1.4. The contrast gets a generous bump when stopping down.

The sharpest focus wide-open has a lot of purple fringing and is not the sharpest focus at f/2.8. For sharp results stopped down it is better to minimize the purple fringing when focusing. Like the Minolta 50 F1.4 this lens would benefit from stopped down focusing which is not possible on Sony cameras without using a third-party adapter that has a manual aperture control. The EF version has much less fringing.

The first reviewer below misstated that it is focus-by-wire, but it uses a normal focus clutch mechanism just like other SSM lenses. It can be manually focused off of a camera--no wires used or needed.

The plastic HF012 petal hood is shared with the SP 35mm F1.8 lens.

positive:Very sharp lens, not too heavy for a full frame lens, great build quality. I very much like the focal length, particularly on a crop sensor.
negative:I don't find this lens focuses quickly on autofocus, it is prone to hunting. Some fringing is sometimes visible, it is correctable in post. My copy needed a micro-adjustment.
comment:I like this lens for it's sharpness, I just wished that autofocus was more responsive on it.

compared to:Sigma 35mm Art and Voigtlander 40mm ƒ1.2. Not as sharp as the Sigma (obviously), but no slouch either. Much better than the Voigtlander, except at subject isolation (to be expected from a ƒ1.2 lens).
price paid:399 (new)
positive:Very sharp, even wide open. Nice manual focus feel (even though it's focus-by-wire). Autofocus works well on both a-mount and adapted to e-mount. Incredible bargain.
negative:Some fringing at wider apertures; generally correctable in post.
comment:Very nice near-normal focal length lens. I use it on an a99ii and an a7Rii (on the LA-EA3 adapter) and it works well on both.
