Re: Cosina 28mm f/2.8?

I don't know the specific lens, but I do have a Cosina 24/2.8 and it's below par. Most Cosinas are okay, but not really good. There are some exceptions, but unless you know for a fact that this lens is one of them, better not to buy it. There are many better choices in the same price range. Try to find one of these:

Vivitar 28/2.5
Sigma Super-wide II 28/2.8
Tokina RMC 28/2.8

These are all very good. There are even better choices out there, but the price takes a pretty good leap.

And that's why we are talking about the lens right now smile

I know about the others, just found the Cosina locally and wondered if it is worth it.

Thanks!

That's yet another issue -- the price is way too high. This is a lens that might fetch $10 on ebay.

Thanks for the links, montecarlo. Useful, being able to check the aperture in the exif data; I'd love to have it avaliable on my eos!
Seems like my google skills were a bit off the other day smile

Re: Cosina 28mm f/2.8?

I have this lens. It's easily the worst of my 28mm's. Worth about 10 euros in my honest opinion. My Zuiko 28/2.8 is much better.
