Turning film cameras into digital cameras

Could it work with medium format TLRs? The shutter is in the lens. That old Rolleiflex in the closet could have a new life as a digital camera. My 50s Rollei TLR produces lovely 77MP files without any modifications whatsoever. My sentiments exactly, but we are just fantasizing about a digital insert that will never be produced. 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) |

What I am thinking about is just a 35 mm film or a 120mm film cartridge similar to the one proposed as the silicon film/e-film. Nothing more and nothing fancier. If it becomes a device in which you have to open the hinge of your old camera and attach a digital back.... it does not serve the purpose. I am thinking about an exact replica of 35 mm or 120 mm film cartridge, that you drop into the slot, engage in with the lever device to cock the shutter, the way we did it the old fashioned way in the past. Someone mentioned that there are too much things to put into that tiny cartridge. However, technology has changed in the past 6 years alone. People can now jam in 2 GB (or even 4 GB) data into that same SD card. Can we jam in a tiny memory chip into the 35 mm cartridge? Then, add a tiny battery source (rechargeable, just like that mini shuttle ipod that clip in your shirt and play music.... they can do it). My whole point of the start of my discussion is whether the technology is now possible. I know, there are a lot of other obstacles on the way, and perhaps the biggest one is not related to the technology at all, but to the willingness of the industry to serve for the consumer... (yep...that is all of us). The camera companies are now in the business to sell new digital cameras, and they said their way or no way at all. They have so much resources that can throw away something that can be perceived as a competition. Someone indicated that there may not be enough space for the processing and storing of the data. However, it should be noted that the camera body is the one that function to select the shutter speed, the aperture, and other things (timer, synchronization with flash, etc). The job of this 35mm cartridge is just simply to record into a digital format, until it is ready to download into computer.... nothing else. If your old Minolta maxxum, Olympus OM1, Fujica ST 801, Canon EF, Pentax K1000, Konica T3, Nikon F-1, Yashica MAT 124, Mamiya M645, or others has their own disadvantages in their system, this 35 or 120mm cartridge are not supposed to change or help the camera body. It is the job of the camera body to get the shutter speed to open (at the right time and aperture). The camera will have the job to advance to the next film using its lever. If the camera has a multiple exposure feature (such as my old T3), when it will disengage the sprocket to advance the film, so that the next shot, the e-film in the 35mm cartridge will be exposed twice or three times, etc.... just the same way it did using regular 35mm film. Someone also mentioned that perhaps no one want to use the old camera. The question would be if there are lots of people still want to use the old cameras. Well... this is just a discussion perhaps these people already invested and was happy with their old gadgets and want to continue using it. The point is to make the new e-film as simple and as close a replica of the old film cartridge. Of course there are perhaps many other challanges..... However... if in the past you buy a 35mm cartridge and drop into your camera.... it is supposed to work, right? whether it is a Nikon, a Fuji, A Ricoh, a Leica, a Praktika or other brands. This is exactly the idea. That e-film or silicon film introduced/ planned in 2001 was only limited to specific cameras.... and I think that was the defeat. To make it work this time, the cartridge has to be as simple as possible (perhaps can only be used for limited number of times, depend on the wear and tear of the e-film. It has to be able to be dropped into a $1000 camera, or a $30 vivitar old camera... Thanks anyway for all the discussion.... it has been a very interesting comments. |

I wasn't talking about a digital back. I was talking about a 35mm size roll of film with a piece of film out sized package then went right in to the 35mm camera film compartment. You then closed the back just like if you had put a roll of film in it. This is totally different from a back as it could also be used with any type of 35mm camera. =(8) |

This is totally different from a back as it could also be used with any type of 35mm camera. =(8) The first problem that I can see with a generic drop-in digital film replacement is that every camera design put the film through a slightly different path. If the digital film sensor is aligned to fit into a Nikon F1, then it probably wont fit properly inot a Canon T1 or a Pentax K1000 or a Olympus OM1. Then you also have the problem of interfacing the shutter mechanism with the sensor so that it knows when to start and stop capturing, what may work on a Pentax Spotmatic probably wont work with a Canon EOS 300. If these were the only hurdles to designing and building a drop-in digital film, then Imagek should have been able to solve it and not fail and then vanish in a cloud of vaporware. |
