Moving CF card from 400D to 40D

OK...so I should have known better, but when I sold my 400D to help fund my 40D I never got around to transferring alot of shots off the CF card before I sold it (I kept the card).

Now I seem to have misplaced my card reader too......

My question is - if I put the 'old' 400D CF card into the 40D will it a) screw up the images or b) screw up the counter on the 40D? (the 400D was in the 10's of 1000's).

Anyone help?

You can load the cf into the 40D and transfer directly onto your computer using the provided USB. You don't need a card reader.

Your own 40D will start counting at 1, I'm assuming. Doubt there would be conflict even if the numbers caught up. The naming system probably differs from the 400D, but I'm not sure.

Actually, if you insert the 400D card into the 40D, the 40D will pick up numbering where the 400D left off. You'd need to do a manual reset with a freshly formatted card to get things back where they were. Pick up another card reader. You can always use another one. What I can't tell you is whether you'll be able to transfer the 400D photos from the 40D. You should be able to, but it's possible the camera's firmware distinguishes other camera's shots and chokes.

Well, I managed to find the card reader eventually......so I'm in the process of transferring 100's of shots to my PC, at which point I'll delete everything and put the CF card in the 40D.

I can't remember if there is a facility in Photoshop or EOS Utility to format the card, probably won't matter as once the images have been deleted it shoudln't affect the 40D's counter.

Oh...and if you are wondering why I am not using a different card it's because I sold all my others with the 400D - and I just can't wait until tomorrow when the shops open to try out the 40D.

The 40D will format the card.

If you don't want the numbering to pick up where the 400D was format the card in the PC and then put it in the 40D and format there. That will preserve the 40Ds numbering sequence.

I will add still another guess to what everyone else has said. My bet is the 40D will create a new folder on the CF card and ignore anything the 400D has put on the card including the file numbering. I would also guess that connecting the 40D to your computer will not get your shots from the 400D off the card. My suggestion is go buy yourself another CF reader for $20.00.

Play safe - format in the card reader then again in the 40D. That is the only way IMO to ensure nothing is left on the card that can influence the 40D count or anything else unforeseen.

Instead of assuming, betting and guessing, why don’t you read page 72 of the 40D Instruction Manual, File Numbering Methods..

I agree with that..

I don't see what is so important with the count anyway - it's just a file numbering system. For the record, I have a 350D, and I used the card from that (used about 20,000 shutters - reached around img 1400 again) into my new 40D, and it just started at 100-0001. Put it back in the 350D, it carried on from 1400. Back into 40D, back to its numbering. With or without formatting (I definitely formatted it before I stuck it in the 40D, so this may mean something).

Possible only if you had your 40D in File numbering Auto Reset mode and 350D in Continuous..

Or reformatted the card in the computer before moving it over to the 40D. The camera will use the higher of the number on the card or the last known number in the camera while on Continuous Numbering.

both my cameras are on continuous. Both continue to take images where they left off on the same memory card. I can't remember, but I am formatting them occasionally from the camera itself. However, I have definitely taken images on the 350D while it had 40D images on there, and the 350D has continued to where it left off and not renumbered from the file.

Maybe it has something to do with it being a 350D (not 10.1 MP file). Images from the 40D definitely show up on the 350D screen, but some details are missing on the info window.

No - if the frame count on the 350D is higher than the frame count on the 40D, the 350D won't get the count reset. The camera takes the higher number from either the card or its internal memory.
