I have a mirror finish folding Rolleiflex lens cap. I was wondering how I can tell which type it fits. I have a Honeywell 3.5F and it locks into the taking lens but is shorter than the lens on that camera. When unfolded it doesn't cover the viewing lens. (Or do I have that backwards? It's been some time since I attached it.) The cap is a little smaller than 3.5 inches including the tab on the bottom of the cap. thanks Chad
The bay 2 cap got bigger after the E. You have to be sure you get the right one. The gap between the lenses changed by a few mm. Measure the center to center distance and make sure next time you get a bigger size. There are only two sizes.
