Digital film cartridge.
So why don't you work it through? Maybe a Dragon will cough up some cash to get it going? :lol::lol: How do you power the sensor just out of interest?

Digital film cartridge.
Anything exposed to the sensor is written when the "wind on" mech is activated. I don't think that will work or do the camera rewind the film while it's getting expose? Why does the sensor need to talk to the camera??? a film doesn't. Film is always sensitive to light a sensor isn't, it needs to ...

Anything exposed to the sensor is written when the "wind on" mech is activated. I don't think that will work or do the camera rewind the film while it's getting expose? The sensor just pools the incident light until the wind on mech turns and then its written to memory. Only if the shutter fires wo...

Indeed that's an option but it drains a lot of power to have the sensor on all the time and it produce heat and with that you also get more image noise :(

Fit a small IR sensor to the edge of the frame window, as soon as the curtains move it fires the sensor, this will give a fraction of a second for the sensor to power up (no idea what the power on time of a sensor is) and take the pic. the 'inputs' you have to control the cartridge would be: mo...

The sensor could be switched on when the film wind lever is advanced. If no exposure takes place within 3 minutes, it would automatically switch itself off. The sensor would write to SD or Micro SD card after the shutter fired. (Not CF card, as I said in the original post.)

Digital film cartridge.
I hate to be a damp squib but there's something else you need to take into account: Film is thin, very thin. To make a "universal" sensor that works in all cameras you'd need to make that the same thickness, otherwise the registration distance would change and you'd lose infinity focus on all len...

Digital film cartridge.
there is a bit of slack on the film pressure plate and its the back of the sensor it has to focus on, the glass layers on the front are not an issue. so long as its mounted on a VERY thin circuit board then you should be ok, think the flexible kapton board and you should be able to make it work.

If you can make one and bring it to market for the right price then I'm sure there'll be a few bob in it for you... :wink: Not really my area, I do audio. they guys above me at work do imaging and facial recognition stuff (Rich made a very cool computerised face that mimicks your facial expressions ...

Digital film cartridge.
PhaseOne would probably be the people to speak to IIRC they have rights to the SciTex company that pioneered a lot for the ultra slim 'leaf' sensors (bought it off Kodak I believe). They don't seem interested in anything as small as 35mm FullFrame though, they have been doing meduim and large format...

Digital film cartridge.
Current sensor tech is better than the lenses we have so I see no room for saleable upgrades. Really? Better not tell the marketing department of Sony/Nikon/Canon/Pentax/etc that then so they'll have to stop selling us new DSLR's with upgraded sensors every 18 months...

Digital film cartridge.
Well numbers are easy to sell, but if you take a canon 5D II or 7D and take some piccies with a good lens chances are if you pixel peep then you will find 'errors' in the lens, distortion and chromatic abberations, IMHO that makes a sensor beyond the abilities of the lens. Especially with crop senso...

Skills vs Camera vs Lense.
I was talking about how the photos looked so artistic and creatively. same lens,same way of taking picture but different body....will it make a difference???? Yes and no. The way the photo looks artistic and creatively won't be different, you can even make very good photos with the camera in you...

Skills vs Camera vs Lense.
is it because their photo are more artistic or creative than us? or how hard they do it because of lack of tech that time? same lens,same way of taking picture but different body....will it make a difference???? It depends. For low light a body with a good sensor can give less noisy pictures o...

Tamrac v Kata
I've used a Kata DR-467 for almost 2 years now. Upon arrival I was suspicious of it's durability and protection because it is very light compared to similar backpacks from other manufacturers and the main straps seemed to have weak stitching where they exit the top of the bag. I can honestly say tha...

print size vs mount vs frame
Noticed same problem myself. Set all print sizes on my website to match my 1.5 crop sensor but very few frames to match. In the home, I have been using A4 and A3 as these frames are commonly available. Either that or crop everything square :wink:

No more Pentax for me!...
I will not buy another Pentax Dslr again... Unless of course, they make a Full frame one. I love Pentax equipment as much as anyone in this little community.. Except perhaps John, who I think, if cut in half, would have 'Pentax' written through the length of his body, like a stick of Blackpool rock....

Oh, no! - I don't want to start up another FF thread. Yes, It has been done to death. I am just thinking that Digital photography is no longer in it's infancy. Perhaps now would be a good time for all the manufacturers to agree on a standard for camera sensors. Just two, for high end cameras. FF...

No more Pentax for me!...
I imagine, mowog, that you have a pressing need to make enormous enlargements or to make extensive and regular use of very wide angle lenses. Full frame would certainly be of benefit in these cases. APS-C has become so accomplished that it's supposed to be hard to see the difference in "normal" s...

I didn't mean this to turn into another FF thread. But It seems I need to explain why I want an FF camera. It has nothing to do with image quality. The APS sensor is capable of that, way beyond my, and most people's abilities. Even if FF sensors gave slightly inferior image quality, I'd still wan...
