Here in the last few months I was given a mint Nikon F4. The guy I got it from retired and had it in his locker. beuatiful camera. it came with three lens and flash. Where I'm I going with this...? As most of us use medium format cameras I'm fighting in my head in regards to go shoot with Rollei or go out and shoot the F4. Do you guys go back in forth in regards to shoot a particular format, regardless of camera? Do you alway go back to the old faithful? I'm always thinking if I see something and have the wrong camera. I'll have regret not shooting it with Rollei.The insanity!!
