Sony FE 28mm f/2 Lens Review

I bought it for my Sony A7S II and Sony A7R II. It will work with Sony A7 (I and II) as well (and with other Sony E-mount cameras). Physically and mechanically I love this little lens. It’s so lightweight and pretty tight, doesn’t feel cheap or loose like, for example, many Nikon DX lenses I have used. (A side note: Nikon’s pro lenses are very tight and feel awesome.)

The image quality is quite decent, actually great for the price (it goes around $450 USD). But there are some issues that bother me and many other users. Zeiss 55mm f1.8 has much sharper image, and all that across the entire full frame. It costs about double though.
Sony FE 28mm f/2 is very good around the center, and a bit softer in the corners. Stopping it down (f5.6 – f8) helps a bit, but the overall sharpness is not quite excellent. Its second issue is very heavy barrel distortion. It shouldn’t bother if you shoot flowers, people, animals, skies, etc., but it becomes an issue if you use it for buildings, interiors, cityscapes, straight landscape sceneries. It can easily be corrected in post processing, but then you’ll lose some resolution and image sharpness near the edges and corners.

Its image quality seems to be better with Sony A7S II, I guess because it has only 12 megapixels instead of 42 megapixels (Sony A7R II), which makes the lack of corner sharpness less noticeable.

It’s really light and small, I can put it in my pocket and not even feel it in there! Its focus is silent, but not lightning fast, I’d say average. It actually bothers me that it doesn’t have a dedicated AF/MF switch on the lens barrel. You would have to switch between AF and MF by pushing the right button(s) on the camera body.

I bought a Kenko 49mm Pro1 D (Digital Multi Coated) UV filter for it to keep it on all the time (mostly for lens front glass protection purposes). You don’t need the most expensive filters for wide angle lenses, average (branded) filters work well enough (I’d avoid cheap unbranded generic Chinese filters), and make sure they’re multi coated. I’ll talk more about lens filters in a separate article.


The bottom line: it’s very convenient to carry it with you, you won’t even feel it, and it also doesn’t add much weight to your camera either. Also a great lens for shooting video hand held (lightweight!)

For the money it’s a great lens, and for some reason, to me it’s the cutest lens I have… go figure…
