What a neat idea! I've never heard of it being done, but I'd imagine you could modify a G body cap by cutting (drilling?) a large hole in the center and attaching (gluing?) a piece of brass sheet stock with a pinhole to it. Should be relatively easy to do.
If you do try using your G as a pinhole camera, please do let us know how it works out.
Well, maybe here's a good forum to start some discussion going.
There are some questions that I myself am not sure of the answers.
1. Exposure calculation. Is there a way to trick the camera to switch to external metering like when one mount the 16mm onto it?
2. Focusing and sharpness. What i know is that for a pinhole camera, it will be sharp throughout, but the question is does the location of the pinhole matters? (e.g., should I stick the brass sheet of the outer or inner portion of the cap?
3. Will the shutter plane be burnt through? Probably will not happen, but don't think i wanna find it out the hard way.
Anyway, thanks for the response. At least I have an indication that I am not going off tangent here.
wow, harsh. sometimes the point can be just to see if you can do it. aside from that, the body of the G2 also has a lot of control over the image such as continuous wind, etc. I say give it a try for fun!
everyone, thanks for all the comments.
I am sorry if it seem sacriligious to a fine camera to suggest building a pinhole camera out of it. Well, my reason is purely simple: to see if I can do it. Besides, it saves me the money to get a new lens for my christmas present this year ; )
Here's a status report of what I have done so far. In an attempt to understand the workings of a pinhole camera;
I constructed a simple light shield with a small pinhole. Stuck it onto a bellows unit with a SLR on the other end.
The SLR is so that I can see the image and the effects, bellows unit is to check out the effects of different focal lengths.
Haven't done it for the G body yet. Waiting for the body cap stock to arrive.
Anyway to make a long story short, I got what I am looking for: a challenge.
I think it's great that you're pursuing the idea! Please keep us posted on your progress. I'm especially interested on where you place the "lens" in relation to the film plane (distance from) and what hole diameter gives you best results (you'll pwobably want to try several).
I've coined a name you can feel free to use: the Hole-ogon.
G2 for Pinhole !?
Its like Pulling a Caravan with a Dodge Viper or a Ferrari.
Would you really drill a hole in a 20Dollar Bodycap ?
The Exposermetering wont work anyway. There are several Cameras for Pinholephotography available usually very cheap.
Skip this Idea !
Voigtlander has got a Pinhole lense available and with a Voigtlander RF Body (its a Yashica) makes it a much usefuler equipment, also get a lightmeter.
