Vivitar 28 mm 1:2.8 MC Close Focus Wide Angle [OM]

It is a beautiful sunny day today. What's more, I couldn't stand noise in my apartment - my neighbour is having some major repairs done. So I took my Vivitar for a walk in the fields.

I remember I rather gave up on this lens. Well, it's nothing pretty special. Focal length 28 mm and aperture 2.8 doesn't make it unusual in any way. I got it with my Olympus OM-10 and used it with that camera as wide angle lens only. But attached to a Micro Four Thirds it gives you eq. of 56 mm @135 type.
As I checked out some online offers, it turns out it's a rather cheap and common lens. Close-up gives you more opportunities to use it. Take a closer look at snaps below.

Vivitar 28/2.8 is really convincing lens for field photography, close-ups and macro shots.

Vivitar 28 mm 2.8, distance to object ca. 11 cm/4.33 in. - closest I could focus at.

Vivitar is sharp from 2.8 and has a really nice bokeh. I wish it was faster, but still really nice.
Camera: Lumix G2
Aperture: all photos were taken with aperture F2.8
Mount: M4/3 > 4/3 > OM
Edit: PS CS6 50% scaling

I was curious how it works against the light (as you remember Zykkor had major problems with sharpness and contrast). I've found some nice flares @F16. You might say it's a flaw, but I'm not looking for a perfect lens, but for one that works for particular task.

Last pictures show how aperture changes. There are six major steps shown below, but there's also a "click" between them, so you can get 1/2 EV correction.
