...instead of only able to change lens,
you can now change the sensor (pop it in like a memory card)
and that would make the dSLR almost like the original SLR!
no more worries of sensor dust, hooray! :)
seriously, do you think this is a good idea? costs-aside. |

| i'm pretty sure the sensor is very delicate. You might not want to touch/handle it if at all possible. The cost would be astronomical. Getting a proper cleaning kit would be a much more practical option. |

I don't think that would work well IMO. If it is so easy to get dust on the sensor just by changing lens we would most defiantly get dust on the sensor by changing sensors.
However I wonder if a dSLR with three separate sensors one for R, one for G, and one for B all separately to gather more detail would be feasible or applicable.

good thinking, but how should they be positioned? hmm

same as a 3 ccd Video camera..:) |

wow I never knew about 3 ccd videocams. Hmm, in that case, I would say that a 3 sensor still camera would be damn good, eh? |

I don't know really but here is an idea
Read this about 3ccd cam
I guess others have pondered the Idea. Read this forum post from dpreview dated 1/12/2006

| interesting idea, but this would make for one big heavy camera :-) |

| I beleive all this is technically feasible. A dSLR with a user changeable (upgradeable) sensor and even autofocus module. But why would any vendor want to do that? It would kill sales. You would buy one camera for life! |

I'm old enough to remember when CPU's were fixed on the motherboard.
Then along came cpu slots and zif sockets and all of a sudden we were able to swap our CPU's at will.
Maybe one day down the track it could happen.
cheers,

Well, the sensor is the single most expensive and critical part of the camera. The problem with having them interchangeable, or "a" problem I should say, is that extremely precise positioning/alignment is required in order to have good focus. I don't see this happening, at all.

this is old news.. Sigma has a sensor called Foveon in their DSLR line, it has 3 layers 1 for each color, so it's already available, and the colors are much better than in the Canon or Nikon CCD and CMOS, but it's expencive to make and I think Canon and Nikon still produce better image quality even with worse color palette..
as for the interchangable sensors, it's already available.. on medium format cameras.. the Phase One digital back is interchangable, at the moment yoy can get them at 16, 22 and 39 Mpixels and I think there are a few other sizes available.. and they can be replaced in less than 10 seconds.. and you can even put a filmback on the camera instead of the digitalback :)

It works for medium format cameras with digital backs, but for a dSLR I do not see any significant cost advantages.

but doesn't that proves that changing the sensor doesn't need a PhD to perform? and no need for a clean-room setting too, I assume? |

Nobody's seriously heard about the Leica DMR?
It's been around for ages.
Google with logical keywords to find info on it. |

In the old days we all changed film ourselves without too much problem.
I guess all that would be required to apply it to digital is to have some sort of optical calibration tool in the camera that would work much like the one in my 4 year old scanner.
It goes through a calibration routine everytime I change print cartridges.
Anyway...time will tell.

that would be great!
when it gets dusty just take out the sensor and pop it in the dishwasher :)
i thought the sigma dslr was a type of 3 ccd? |

Interchangeable BACKS is a whole different beast than what was being noised around here; the actual removal/insertion of a sensor in the body. These sensors are SMALL, they are DELICATE, they have to be perfectly positioned and connected, etc. Your interchangeable back, the sensor is locked into the back perfectly securely, all set up to go, connected up the wazoo, and the back itself has a precisely-machined, mechanical interface happening with the camera body.
I don't see any possible future that has us sliding sensors in and out like CF cards, is all I mean...
