Camera saved photos out of order

I was taking a few photos of an office building. Got back to my desk to review them and discovered a weird issue. The camera had saved one photo out of order. IMG_7226 was taken later than several subsequent photos (7227 through 7233), something confirmed by the EXIF info which shows it to be the last image in the series.

So now I'm wondering, anyone else seen this happen? I've never noticed it before but when you have a series of similar shots it can sometimes be hard to tell. I'm a little worried that it may be randomly overwriting earlier photos.

Camera is a 300D, never had any issues with it or the memory card in use before.

Did you, perhaps, open the card door with the camera turned on during the shoot? I can't think of anything else that would cause the problem...never saw it on either my 350D or 400D. If you do find out, please post.

Nope, card door remained closed (unless I managed to accidentally open and re close it without realizing) and the camera remained on until I was finished. I didn't turn it off, instead just letting the time out thing take care of that.

Might you have deleted one and the camera then re-used that number? Just tossing out ideas.

I didn't delete any (I don't tend to chimp too much). I'll look into what happens though, if you delete one would the camera go back and fill in the gap? I don't actually think it would, I think the always increment. Does make me wonder though, why did it jump back, and why did that particular file get overwritten.

I have had that anomoly happen once or twice myself. The image data is fine, it just was out of order. As suggested, the door may have been accidently opened. Rapid manually on/off in certain cases will duplicate a folder number and put the odd number in there. There is an off chance that you have a bad sector in the card and it bypassed that area. On occasion a 'half-frame' was recorded with the upper/lower portion just black with no info shown. My 300D was pretty darned stable for the most part.

Did you by chance do a hot swap of lenses?
If and when you find out for sure...please let the rest of us know your results.

Nope, no swapping of lenses.

Maybe it is the door thing? The camera was in my hands the whole time, but maybe I managed to slide it open enough to register without actually realizing.

I'll see if I can find some kind of scandisk for flash memory thing. I wonder if I can get windows to do it? Be interesting to see if there are any bad spots on the card.

RAW to JPG?

Did you switch to a program mode from shooting RAW to a mode that forces you to shoot JPG? It could look out of order that way.

Nope, these where all just some quick shots for a website so it was 100% jpeg the entire way.

I wonder how common this is. Sounds rare which would make it harder to diagnose but I guess sometimes it could happen and just not get noticed.

That has happened to my 30D a few times. I would shoot shots, then put it away. Pick it up later, shoot a few more. repeat.. Then when I down load, some are out of order. I never switched to RAW, and as far as I know, did not open the card door..???? Dunno...

right click, arrange by name??? lol

File erase gets me out of sync. I fire one I know is a loser then jump on it and erase it in the field. Back home i'm passing the frames suddenly the next one pops up that I remember as being a half an hour after what I was just watching. Nothing wrong with the cam.

Well yeah but I didn't erase any. The camera decided to do the overwriting thing. Soundslike its not limited to just the rebel if the 30D can do the same trick. I doubt its a huge issue otherwise it would be talked about a lot more. Still, it does leave me concerened that the camera (or at least the whatever the unknown circumstances were) may in the future lead to the loss of an important photo.

I have had that happen with my G3 but I do tend to chimp and erase a few shots that are just bad. I guess I had assumed wrongly that if I reviewed a series of shots and deleted one out of the middle of that series then that particular deleted file # would not be used again unless the files were downloaded or the card was formatted.

Does anyone know for sure that if you delete a shot out of a series, say #5 from the series 1-10, then the next shot would be #5 instead of #11? I didn't think the camera recorded files that way but that seems to be what some are suggesting.

I'm with you, I thought the camera would just increment. I didn't think it would go backfill deleted shots.

I think tomorrow I'll see if I have time to test some of this stuff and see if I can repeat it.
