Novoflex 400mm f/5.6, 600mm f/8, various mounts, and extenders. Novoflex Pistol grip focus F5.6 400mm and 600mm tele lens shoulder sniper Noflexar 400mm f/5.6 and 600mm f/8 lenses from Novoflex, a West German company manufactured in 1955. Includes Rollei and REXA mounts. It's rare to find items from this year in such a clean, scratch-free condition. The construction of the shoulder stock and other parts is also superb, reflecting the quality of German craftsmanship. In the fourth image, tightening the round knob on the top allows you to lock the focus mid-way. While not practical by today's standards, it's a unique and rare item for enthusiasts. The size selection above is set to Canon because the appropriate mount is not available. Please refrain from purchasing if you are overly concerned about minor details, as this item has been stored at home.
