I don't think DX coding is something you get, I think it's something you've got or don't got
As I recall, the Fuji GA645Zi has DX coding. I guess my 645 af has it, I dunno. Irony is, I never trust it when the camera I'm using does have it. But it always works. But I don't trust it. But it always works....
But let me just say (in all semi-seriousness) that I don't see why someone would take pride in doing reciprocity corrections. I'd say reciprocity falls into the category of those logarithmically brainless activities that take time away from actual composition. So the original poster's intentions are good, and if film camera development had continued full steam then I'm quite sure that cameras and perhaps also light meters would offer DX-coded automatic reciprocity correction.
I'm looking for a camera that doesn't need a photographer and makes 1st class shots.

I've had an interesting situation with a friend:
[I show him my OM-1]
Friend: Wow, nice one. Does it take nice photos?
I: Well, all depends of the photographer. It doesn't take photos by itself.
-[I put the camera on the table with the film cocked and ready, no selftimer]
-[wait 15 sec.]
I: See, It hasn't taken any photo.
Friend: (weird wink)
I sincerely hope this never happens, It's bad enough when your employer makes you redundant, but even worse if your cameras do it to you.

You could have the camera prompt the user for a Schwarzschild exponent, but that would confuse 99.99% of the market, and even those that know what that means may not know it offhand for the particular film they have loaded.
In the end, it's one of those things that people who need it will do better than the camera. For the way I work, even setting a normal length exposure falls into that category 99% of the time.

Good morning, Ajuk;
From my reading of the manual for the Minolta Maxxum 9 / Dynax 9, not even that "feature" ridden product of "the Mind of Minolta" has that capability, even though the shutter is capable of getting you into that territory. Normally, reciprocity failure is not really a problem until you get to about 1 second or less than about 1/10,000 of a second. Except for a few people using cameras in certain scientific study, most people are not concerned about this film deficiency.

When they ask you; "How many Mega Pixels you got in your camera?"
just tell them; "I use activated silver bromide crystals tor my image storage media."
What about high intensity reciprocity failure, such as with flash? Reciprocity failure isn't only encountered in long exposures.
RE: my comments above about DX coding, I'm not saying that the existing DX codes can furnish enough info for auto reciprocity correction, I'm saying that the coding method of transferring film info to the camera could easily be expanded to provide correction.
Yeah that's why I thought of those last gen camera that could possibly recive an updated database by being connected to a PC.
