trying to identify lens type for konvas camera
Posted 01 September 2008 - 10:30 PM
I'm kind of new to lenses so I'm trying to identify what this lens is.
Is this a 35mm lens?
The markings read: OKC11-35-1 890241
f-stop #s are 2.3-16
focal distances 1-10 then infinity
so ok, could anyone tell me which company made this lens? the company name does not appear on it
just 52mm UV Japan
is it a lomo lens?
I've heard the terminology OCT-18 OCT-19 and PL, would this lens fall under any of those categories?
I don't know what those mean.
How much does a lens of this type usually sell for?
Here are some pictures of the lens:

If it reads OKC11-35-1 does the #35 always indicate the mm size in this case 35mm for these types of LOMO lenses?

First digits designate film format (16 or 35mm). May be missing.
OKS means 'cine lens' in Russian avvreviation.
Next number states lens model. Larger number means newer and better lens usually.
Next number means focal length (35mm in your case, or 50mm in my example).
Last digit shows variation of the lens model.
As to manufacturing year, let me correct James. This year designated by first 2 digits of the serial number. In your case of #890241, you have 241-st lens made in 1989. So, james is right that it is goodd and relatively new lens manufactured only few years befor production has been stopped.
As to price of these lenses, this question is actually hard to answer due to RED mania mentioned by James. We tried to make oct-18 adapters of Letus and RedRock Micro M2. Redrock can't be made. Letus will be made, most probably, when my tech reciver from a flu. I would like to try to make adapter for RED, but no one sent me a reference mount yet, so I'm still seeking a way to get technical specification of their flange to see if we can make oct-18 to RED adapter. I we do, price of oct-18 lenses will raise quickly as it was with OCT-19 lenses, because both oct-18 and oct-19 lenses have similar optical blocks (and quality therefore), and only reason of their lower price is their inconvenient mount system.
