So since Leica started to 'reissue' some old lens-designs, a 50mm Elmar (preferably 1:3.5 with modern glass) with the old but straight-line mount of the bayonet-Elmar would be more appealing than what they have 'reissued' so far. Mnutzer, roger1987, Lukas F. Pictured here is a nicely done fake Barnack 'Leica II' # 387234 with fake Leitz 50/3.5 Elmar lens. Once upon a time before the internet was popular (mid 1990's) entrepreneurs could turn a quick dollar by remanufacturing an official Russian Zorki or Fed into a reasonably believable 'Leica.' There's no reason that I know of to think that the Elmar 50mm f/2.8 is the sharpest lens ever made. The 50mm Summicron, though, has long been the gold standard for lens performance. The current formula, including the tabbed model, has the lowest flare/best contrast.
