Polaroid DS-34 GelCam

This is the latest weird and wonderful addition to my camera collection - a Polaroid/Fotodyne DS-34 GelCam, apparently used to record Gel Electrophoresis.

It's a pretty interesting camera. It takes regular Polaroid/Fuji packfilm (FP-100, FP-3000 etc.). The rollers and stuff were pretty disgusting when I opened it up, but it was nothing a quick wash down couldn't sort out. It has a Tominon 105mm f/4.5 lens on the front with a Copal shutter. Shutter speeds range from 1/125 to 1sec and bulb, and apertures from f/4.5 to f/32. The shutter is actuated by a cable release - the pistol-grip handle on the bottom of the camera has its own cable release built in, but the handle can be removed for mounting the camera to a tripod, and the cable release replaced with a regular bog-standard model. There's also a PC flash terminal with x-sync, which works.

Because it's a rigid body with a large format style leaf shutter, it's basically a fixed macro camera. Focus distance is somewhere in the region of about 30cm. Because it was designed to be mounted to scientific equipment using a fixed lens hood type thing, there's no way of telling whether or not you're in focus. I work out the correct camera-to-subject distance by using a shoelace that I calibrated to the correct distance and marked with a pen.

There's no viewfinder either. You may notice the three bits of gaffer tape on the top - I stuck them on to roughly indicate the angle of view. Not ideal, but it'll do for now I suppose!

The best part of it all? It only cost me about £12 :-)

I'll write a more full and detailed post on the camera once I've got to know my way around it a bit better.
