Leitz 400mm f6.8 Telyt-R for Leica R brand_Novoflex and there's no way toThe Leitz Telyt R 400mm f6. 8 lens is a simple telephoto lens for Leica R mount cameras. Simple, as in it has push pull focusing not a helicoid and a simple achromatic doublet lens. Yes, it is literally a tube with a doublet at the end. But also, it's a Leica, so it can't be that bad (it's not that bad at all). In very good condition, with minor internal dust and a slight ding in the filter ring.
