The build quality of the Sony lens is good but in relation to its price tag there's too much plastic involved in the construction. The broad rubberized focus-ring operates quite smooth but it's also somewhat wobbly. In AF mode it is decoupled from the focus gear.

Sony quality, great photo. Need a tripod when using the Marco.

A classic fixed focal 50 mm lens is quite a simple optical construction, usually consisting of 5-6 elements. In the case of the1.7/50 model, produced by Minolta, it used to be 6 elements in 5 groups.

very good image quality starting up from the maximum relative aperture; negligible distortion; well-corrected coma and astigmatism; exemplary work against bright light; correct work of autofocus; good quality of barrel

a bit too high vignetting by f/2.8; chromatic aberration at the maximum relative aperture could have been lower

This is overall a great lens. It produces very sharp images and is fast enough to do handheld shots at lower ratios than 1:4 magnification. For anything 1:1 through 1:4, I'd highly recommend a tripod as shutter speeds will quickly drop.

Very sharp photos

Can be slow to focus; even with limiter

I use this for floral photography in the field. It's so "right on". It's fast enough to catch a clear shot of a flower on a windy day..

Consistent Output; Easily Interchangeable; Fast / accurate auto-focus; Lightweight; Nice Bokeh

"I have been able to capture great images with this lens. Great focus and range."

I love 50mm range macor lenses partly because at that time cropped size dSLRs are more affordable and partly because of deeper DOF they offer. Mine is a Minolta version and it has attached on my 7D for a long time service as a standard lens and a macro one. Very sharp indeed.

Sharpness and sharpness

Absence of USM

The reason I bought the Sony SAL50M28 lens was to get clearer magnification of small objects indoors with the assistance of two photo lamps from a light box kit. This lens is just somewhat sharper than the comparative Minolta Maxxum 50mm F2.8 lens.

It is great news that Sony is adding more affordable lenses to its full frame A7 series cameras. However, although the pricing of the FE 50mm F2.8 Macro seems in line with Nikon's Micro Nikkor 60mm f/2.8 Macro lens, which is generally around £499 and Canon's EF-S 60mm f/2.8 Macro lens is around...
