Exakta 24mm f/2.8 MC Macro Performance question.

baachitraka · Mar 28, 2012

I have this lens now for Olympus OM mount and wondering how this will perform when stopped down. Any experiences...

Is this some rebranded lens or an Exacta mount lens with an adaptor ? Sorry if taht's a stupid question.

Lens mount is screwed tightly to the lens, says Exakta 24mm 1:2.8 at the front and have SN: OM95603271.

The "Exakta" branded lenses had nothing to do with the great classic camera - someone just bought and used the rights to the name. They were cheap and from what I've heard universally poor lenses.

24mm lenses in Exakta mount were very few:
The excellent CZJ 25mm Flektogon, a fairly mediocre Enna 24mm, an ISCO 24mm (apparently very good) and a few obscure & cheap made in Japan lenses...

Perhaps it is this (link points to a review of a Cosina branded 24mm f2.8 MC Macro): http://www.pentaxforums.com/userreviews/cosina-24mm-f-2-8-mc-macro.html

Yes, it looks like that but with Olympus OM mount.

I think it an Exacta lens with Olympus OM mount...

I have one of these with Minolta mount. This lens has nothing to do with german Exacta.
I paid 5 EUR for mine (it had a slightly broken mount which i repaired) and found that I wasted my money.
The very few online comments I found about this lens confirmed this.

My copy has a red dot (no, not LEICA...) in the middle of the front element (inner surface) which gives a soft spot if stopped down too much. In addition the field curvature is enourmeous, focus to infinity and the center is sharp at infinity but the border at 2m.
Certainly "interesting" but not what I consider a good lens.

Unfortunately at infinity two images are not aligned. I do not know whether it is focusing at infinity at all. :-( Thinking to send this lens back...
