I have a couple of neat, older cameras.
One is a Semflex - similar but cheaper than the Rolleiflex. I also have a Ciro 35. It has a smaller window off to one side for focusing (range finder). I learned to take pictures with this camera.
I bought a Pentax MZ-10 SLR to replace the Canon, but it's all electronic. It dislays speed and F stop digitally. I just can't get the feel of it. It ends up staying on the fully automatic setting.
I managed to get my wife interested in black and white photography (she says I have too many hobbies, so I'm working on getting her some of her own). I just purchased a Minlota X700 with 4 different lenses on E-bay. I'm expecting delivery any day now - her birthday is on Sunday.
