As to usage, Tom... Do you use the RF cams more than the non-RFs, or less? And why, if you wish to say. 🙂
I consider digital a tool, like a hammer or a screwdriver, it is what I pick up when I need to do something. What I pick up when I want to have fun, is one of the RF's. My Olympus C-5050z P&S being my first choice if it will do the job at hand.
Today I was out with the Crown Graphic, that big snapshot camera is fun, and it interests folks who see it. You also do not waste film when it costs something like $5 a shot considering film, flashbulb, and making a print. I tend to use it for people photos. My only real regret is that I can no longer get the 4x5 Polaroid Sheet Film. A kind of interesting thing happened while I was out today, one of my friends picked up that big camera and exclaimed in surprise, "Wow, this is real easy to hold". He showed it to someone else saying the same thing. My Crown has the flashgun on it with the red button that fires the shutter which fires the flash (two cables), so the three D-cell batteries add substantially to the weight. The camera is easy to hold, the weight adds to its stability.
Yesterday, I shot a roll of 120 with the Hapo 66E, mostly land/water scapes. This camera is fairly new to me, and I am not 100% sure I have it sorted out yet. I bought it because I have given up on getting a decent 4x5 enlarger I can afford. I do have an Omega B22 that the Hapo, and the enroute Iskra, will provide fodder for. My new (old) darkroom is coming along now and I only need to get an 11x14 easel to have everything. The bathroom/darkroom is now light tight and near ready to go operational. That is kind of exiting for me.
My 35mm RF is a Canonet EE1.7 GIII, I have had it the longest of any camera I currently own, since about '93, I think. It is the third of those I have owned over the years. One of my favorite cameras. I admit that it has had a roll of color film in it for a long time, that I need to finish up. It is my stealth camera, quite and unobtrusive.
I have always loved RF's, my main professional camera back in the day was the Mamiya Universal Press, I had two of those over the years. I love their Leica bright range/viewfinders. I have always found that RF's are easier and quicker to use for routine photography than SLR or TLR cameras. I admit that my old Rolleiflex was my favorite portrait camera. And, I have used Pentax SLR's for decades, my favorite being the MX (that is my current film SLR outfit).
These days photography is becoming strictly a hobby for me, with no attempt to make money from it as it was in the past. So my main requirement for a camera is the fun factor.
