A black and white Eos? Using a molecular chemical recording method with resolution that can be measured in the microns (as low as 3 microns)? I'm sure you all most have heard of this... It's called Film. Yes, this is a canon film EOS SLR. I'm pretty sure you can use it with your already existing super sharp, state of the art, canon eos lenses and obtain stellar results with ultra high resolution black and white film. Check freestyle photography some of the 35mm stuff is rated way over what the best drum scanners can resolve. For example ilford has a pan 50 and rollei makes an advanced technical pan that is built on high resolution surveillance technology. The best drum scanners for this type of film have a 3 micron aperture and can scan at up to 8000 or 12000 pixel per inch, respectively. This correlates to a 96 - 216 mega pixel image (using 1x1.5 inches as the area). The question is can your lenses keep up?
Drum scans are expensive, so only use them for your best work. The canon lenses and cameras you already own are the expensive part. This allows one to shoot pure bayer free black and white, on the side, without a whole new top of the line digital camera. The best part is that I am only asking $250 for this camera, the cost of a mear battery replacement for your current canon.
Actually, the best part is that you can use this camera with your current lenses. Good glass is expensive.
The cool thing about this camera as a 35mm film camera is it's ease of use.... It handles much like a modern digital camera with fast shooting, auto focus, light metering, and various camera modes. So even though you are using film you can still be confident that you are getting that shot.
