This would be a first for me as well, as it's not even in the lens db!

There are some photos from Gooshin from this lens (I think):

He probably posted elsewhere about it but that was the first I found.

I am not sure now, but it looks a lot like the Ricoh 18/2.8 (The second pic here)). This is a lens I don't own (yet) but I know I will own in about a week (I know, I have trained my girlfriend very well). I had a chance to test it for a short while and from what I could tell it was a good performer. It murders the kit lens at 18mm and also was conciderably better than my old workhorse (Cambron/insert 3rd party name here/Samyang 18-28mm 4-4,5). As I said, I don't know if they are the same but they do look the same which is often a good indication.

hello Everyone. I am looking to buy a ultra wide lens for my pentax kx and found this on ebay. Any advice regarding the quality and what will be a reasonable price for a used one but good condition?

Thanks and regards.
