I'm not the first to try this, yet I'm sure it is still novel enough to share.
What I want: a
manual focus camera with a
big, bright viewfinder, a
mechanical aperture coupling for either K- or M42-mount, and an interchangeable film/digital back - for less money than a *ist DS.
My solution - take the 'guts' out of a digicam and fashion it to the back of a Spotmatic.
As a proof of concept, I took my Kodak DX4900 (nice colors, crappy interface and controls) digicam and took it apart, flipped the CCD backwards, and slapped it facing the lens of a Ricoh 500G rangefinder. (My Pentax ESII and ME Super don't have interchangeable backs - if someone has a Pentax manual focus film camera with interchangeable backs let me know! For the time being the Ricoh is the easiest to get at.)
For now, I have the digital camera manually set to 1" exposure - I trigger the digital and then within one second snap the film camera. (Any electrical engineers out there who want to help?!?)
Here is the Frankencamera:
And here are some shots with it:
(An abstract, below - I'm going to have to do some calculating to get the sensor in just the right spot. One or two mm off produces some interesting shots indeed.):
So far it works - I'm honestly a little surprised. If I can hack up a proprietary digicam and create something that with a very small step can be incorporated into a modified back for a film camera...why isn't this a marketable product?! How many Spotmatics are still out there? For that matter, how many Nikon F/F2 cameras are still out there?
It looks like on my way to the Digital Spotmatic I've at least come up with the Digital Holga!
Hope you enjoyed,
