IR in a Mamiyaflex C2

[JBrunner]

Anybody know if the bellows in this thing are IR proof? I'd like to know before I smoke a roll of film and find out the hard way.

why not try just one frame of film? I'd guess it might depend a lot on the particular camera & what condition the bellows are in

snip a few inches off a roll and pop it in...then take camera out into bright sunlight for 20 minutes or so w/o taking a shot

That is a possibility, but dissecting and reconstructing 120 roll in pitch dark is a bit of a pain. I'm really hoping that someone can just say -yup, no prob, I do it all the time.

yup...I was trying to think of a simple way, but every idea I have involves fussing with the film

I have a Mamiyaflex also...but not sure which specific model it is...I can't even find a serial # on it

what film is it...Konica?...or someone else?

Not a conclusive answer but Dave Miller has some IR images in his gallery, this one taken with a C330: (there was a url link here which no longer exists)

My Mamiya RB67 is also o.k. with IR film.

Whilst there is no guarantee that the C2 bellows material is the same as the C330, the fact that a C330 can be used with IR would be enough assurance for me to try it out.

In the comments for this image, Dave says that he bought the C330 specifically for IR.

So assuming the bellows materials on these cameras is the same, the C2 should be o.k.


Steve.

That is definitely encouraging...

I used a C330 for Konica IR work and never had a problem. I like shooting IR with a twin lens camera, no problems composing or fiddling with the filter. The Konica film being only 720nm makes it easy, the 870nm films may act different. Anybody know for sure about this?

I'm looking to shoot some rolls of the Efke820 before I commit to 8x10. It should tell me allot.

Nice image!

I can add to that that I have used my Mamiya C3 with Ilford SFX-200 on several occasions without a problem.
I have some Efke 820 and Rollei IR 400 waiting to be tried out as well, but alas, 'tis not the season for IR.

I hope this gives you enough encouragement to try it out.

The C2 has a mechanical film advance lock, so make sure the red window is closed (or tape some foil over it). I would also suggest keeping the bellows racked in when not taking the pictures. You can also raise the internal baffle (unlock the lens change) if you want extra peace of mind.

The older (pre C330s) cameras have more metal and should be more IR safe as a result.

Graham,

That is some sound, and well thought out advice.

I'll just have to try it. I'll report back to this thread.
