Probably 'new old stock' batch of Lomo 22/2.8 optical blocks (complete optics, no focusing helicoid, just aperture system). All blocks taken from one place. All blocks have starting from '90...' serial number, so they all are from 1990 Year (end of Lomo production). Casings of all blocks look nice, with just minimal signs of use, but one casing is not fully anodized black (not an issue, please, check pictures). They do not have serious glass issues, so i do not see haze, fungus, separations, cracks or scratches. As most old lenses, they can have some micro dust inside, some micro marks/spots on coatings and maybe micro cleaning marks here and there. Aperture rings work fine in all blocks. There's some grease on aperture blades, as blocks were never opened and cleaned. This is multiple auction, so i ship them randomly. This is 'as is' auction, so no returns or exchanges, all sales are final. I'm also not an expert in lenses, so i've described them the best, i could. Price 179.99 USD or 'best offer' price is for one block of course. Thank you !
