I have the first version of the Focotar. I hear the second version is an improvement. I beat the eBay price by a good bit by buying it at a garage sale for $7.00. Mine had a Leitz Valoy enlarger attached to it as well.

It is a great lens. Combined with a Leitz enlarger, it is perfectly reasonable to print wide open and not lose a helluva lot of sharpness. We used Leitz autofocus enlargers at the paper where I used to work and we printed nearly everything wide open to get prints done quickly.

It is kinda dark, though. I also have an El-Nikkor 50/2.8 and I now use it most of the time for the brighter image on the easel. Stopped down, I don't see any difference between the two lenses.
