Rolleicord Twin-Lens Reflex Camera For sale is a Rolleicord IV. I bought this camera because I wanted to try a twin-lens reflex camera. The shutter fires properly from 1/500 to 1/30, but the 1/15 setting and slower speeds are sticky and don't fire properly. Also, the viewfinder was dark, so I replaced it with the one shown above. There are some melted parts due to a solvent issue during installation, but it is significantly brighter than the original and makes it easier to focus. I will include the original viewfinder, so please consider it as a bonus. It works properly as long as you don't use the slow speeds, and the lens is in good condition, so I recommend it to anyone who wants to try a twin-lens reflex camera. - Model: Rolleicord - Lens: Franke & Heidecke - Shutter: Synchro-Compur - Viewfinder: Twin-lens reflex viewfinder Thank you for looking.
