I bought an old spanish cam, the famous Werlisa Club from the 60es. But as soon I toke it in my hands I realized the lens were hazy and with a granulated translucent milimetric spots, maybe effect of fungus.
Despite I bring the lenses under more than 24 hours under a UVA-C lamp, the hazy coat got only a little better, and lower better the granulated tranlucent hateful micro-spots...
As well I bought in a chinese bazaar a fake from the Kodak Gold 200, cheap but with an horrible definition.
You can see here I did my better despite those unavoidable difficulties...
But I bought another Werlisa Color, a little newer, maybe from the early 70es or late 60es. With clean lens and good working. I hope my next results with this cam will be more enjoyable.
But sure I will test again this care bargain with a new brand Kodak Gold just for fun ;-)
