Your link did not work, by the way. i doubt there's any demand for a digital back for a tlr. i haven't seen a tlr being used in a *very* long time. the link spanned two lines enclosed in angle brackets. if you use a newsreader that doesn't handle that, manually copy/paste the entire link. here's the main page: http://www.phaseone.com/ |

I saw a TLR in use just a couple of days ago, by me. I have a Yashica-MAT 124G and a Mamiya 330F. The OP asked about a digital film-sized cartridge that could be used in any 35mm camera, not a back. Backs are make/model specific. Such a thing will never be produced, of course, but making one for TLRs would get you past the film plane issue because there is no shutter in the way. The leaf shutter is in the lens. SW |

nospam wrote: In article .com, wrote: Thanks for the reference to the "silicon film", Honestly, I never heard that before. Again, there are people out there who have thought ideas like this. However, I wonder why this particular idea became "cold". Could it be for one or more of the following reasons? the main reason is that it requires physical modification to the camera for it to work. the surface of film is light sensitive, whereas the surface of a sensor is not - it has the bayer filters, micro-lenses, anti-alias filter and infrared cut filter in front of the actual light sensitive layer. thus, one can't just put a filter up against the film rails and expect things to be in focus - it would need to fit further forward. that means either milling the film rails or fit the whole unit within the film opening so the focal plane is physically in the right place. unfortunately, there's a shutter mechanism that gets in the way of doing that. if that problem was somehow solved, there would still need to be some sort of communication between the camera and the device so it knew when to read an image and store it. and then there's little things like a fixed white balance and fixed iso rating when it is the camera (just like film). or a readout for number of pictures available and battery level. other than that, it is a good idea. All of these problems didn't prevent Kodak from making quite a few digital backs for existing Nikon and Canon cameras (the backs were expensive enough that you would get a body for free with the back, but the body was essentially unmodified). -- That was it. Done. The faulty Monk was turned out into the desert where it could believe what it liked, including the idea that it had been hard done by. It was allowed to keep its horse, since horses were so cheap to make. -- Douglas Adams in Dirk Gently's Holistic Detective Agency |

I've not seen anything that looked like a 'film cartridge' but there are indeed digital backs for a number of cameras. I'd think there'd be real practical problems for many cameras. First is PRICE - the "film cartridge" would probably cost more than just a new point-and-shoot digicam if the film camera being converted weren't an SLR. This would probably be true even of better 35mm non- SLR film cameras like the Minolta HiMatic ones. No $4 to park! No $6 admission! http://www.INTERNET-GUN-SHOW.com |

My two TLRs are in regular use, mostly for B&W. SW Black and white could be a practical digital solution not yet explored except (I think) in one medium format digital camera. Monochrome digital sensors don't have the resolution-killing moire filters that colour sensors have and as a result, have 40% higher resolution than do colour (Bayer) sensors of the same size/pixel count. There are many sources for these sensors, Kodak being the main one. You can buy an 11 meg full frame black and white sensors from them. Kodak now offers their huge 39 megapixel sensor in monochrome as well so it should show up in those big Hasselblads as an alternative to colour backs. http://www.kodak.com/US/en/dpq/site/...404_NewSensors |

For my last Nikon (an F-2 film SLR), I bought a replacement prism that incorporated a split-image rangefinder with a Fresnel ring around it, set in the middle of the ground glass. If I could have that in my XTi, I'd probably never turn on AF again. Bob |

Turning film cameras into digital cameras
There was of course the digital film insert a company tried to do early in
the digital camera days. It was basically a 35mm size device with the CCD on what would have been the first frame of film that rested over the proper area in the 35mm camera. It was a neat idea and they had a working prototype. However, they never could get it working quite right. They had too little space to cram a lot of technology including batter for power also the need for a full size 35mm CCD was very expensive. In the end they went belly up. =(8) |
