C220 Focus Question

[jmal]

I just acquired a C220 in immaculate condition and noticed something I have never seen before: the camera seems to be able to focus to infinity and then goes out of focus again when the bellows are drawn the the last 5mm toward the body. I have not yet developed any film from the camera, so I don't know if this is a problem or not. Is this common among some cameras or is the focus most likely out of adjustment on my camera? I guess I'll find out on Sunday when I develop some film. I figured I'd get a head start and ask here. Thanks.

jmal:

The Mamiya C series TLRs (and the RB67/RZ67) cameras rely on the camera's bellows for focussing, rather than a focus mount built into the lens. As they are designed to be used with a variety of lenses, each lens will focus to infinity with different extension to the bellows. For that reason, what you observe is normal - if it didn't occur, the shorter lenses might not focus to infinity.

Have fun with your camera.

Thanks. That makes sense and confirms my own logical machinations. I have to say, if this camera tests okay once I develop some film on Sunday, I'll be really happy. It looks a bit crude to my eyes, but it feels like a very well made camera. I am very impressed with the feel of the aperture ring, focus knobs, film advance, and shutter cocking lever. They all feel precise and leave a good feeling when operating them. I have been hunting for the "perfect" Rolleiflex, and I bought this C220 as a temporary fix, but it may turn out to be the end of the hunt. We'll see.

It may very well be. The Mamiya C220 and C330 cameras are great picture makers and they're rugged as all get out. Not svelte and sexy like a Rollieflex, they just get the job done and done well with more than competent glass and greater flexibility. Try doing close focus work with a Rollie without a hard to find and expensive accessory. It ain't happening. With the Mamiya, all you need do is rack out the bellows, compensate your exposure for the bellows factor (there's a built in exposure compensation guide so you don't have to guess), and you're there.

The C series Mamiya TLRs really epitomize "form follows function".

If, as fschifano suggests, you try macro work, you may want to look for a Mamiya "paramender". It's a devise that adjusts for parallax when doing close ups. Used with a tripod, it raises the camera so that the taking lens moves to the same position as the viewing lens.

That definitely true. The exposed linkage for the shutter release/cable release assembly illustrates this very well.
