The best grip found
Having used Rolleiflex 3.5f cameras as my main cameras and the SL66 as my special effects camera at weddings. I found a foot that attached to the SL66 that allowed me to quick mount the SL66 to the same pistol grip that is used on the Rolleiflex cameras. The pistol grip makes the SL easy to handle and since I could fire the camera with the trigger it made the camera very steady to hold. I don't know if you can find that part anywhere, but if you can go for it. I've been thinking now that I'm retired about selling my SL66 system. I have the SL66 with 80mm, 150mm, 80mm with compur shutter, pentaprism, spotmeter prism and 2-120/220 backs along with misc other gear. I may be willing to sell all or some of this gear, since I'm not getting any use of it. By the way all or most of it is in near perfect condition, as the camera was only used for 12 shots per wedding and the whole system has not had more than 3000-4000 pictures taken with it.
