Can't import 5diii raw files?

I'm pulling my hair out-have the latest version of LR4 and DPP yet every time I try to import raw files from the camera it crashes? It crashes in iPhoto, image capture, LR4 and DPP....All direct from camera as I don't have a card reader ( and shouldnt require one)

Had previously been using jpeg which worked fine. This is very depressing, I've searched and many people have had the same problem but with no solution

What the?

Interesting Bug. Are you using the cable that came with the camera? A marginal one might cause this problem. Which card are the images on? If they are on the CF card can you copy the images to the SD card, remove the Cf card and try the transfer again from the SD card? Maybe the CF card is marginal. There is a menu option to copy images from one card to the other.

I assume that you have the latest Adobe camera raw version with Lightroom. If not you might try updating it and trying again.

Edit- It occurs to me that I should ask you to describe what happens when the camera crashes? Is the battery charged up? A low battery might not have enough residual to transfer multiple raw files.

Hmmmm o.k so I opened EOS Utility and instead of selecting 'starts to download images' I clicked 'lets you select and download images' and tried individually importing each photo and that worked. Out of the 100 odd photos I came across 5 that made the program crash.

From here I couLd then import the photos into LR4.

Any ideas why this could be?

My initial thought is that you might have a flaky memory card or one where the format is just on the edge of being "off". Alternately the camera's electronics could have a fault.
Was the card formatted in the camera before you started to use it? It probably should have been. It could also be that something electronic in the camera is failing.
As a test I would (1) format both cards in the camera then (2) set the camera to duplicating the same raw data when it writes to both cards.
Go out and shoot another couple of hundred shots and then start the manual download process to your PC. If the download fails on the same images from both cards then it is likely something in the camera that is a problem. If it fails from only one card then you may have a problematic memory card. You may have to remove the CF card to get the camera to download from the SD card.

Thanks Steve. The strange thing is the previews load just fine, and JPGS have never been a problem, its just since I changed to raw that this has arisen. I didn't format the CF card so will try that. Also I have only been shooting with the one CF card so will buy a SD card and do as you say-good idea!

Crikey do you really think it could be an electrical problem with the camera?

How long is your USB cable? Is it plugged directly into the computer or a HUB/Monitor with a hub? Have you tried changing the cable?

Just using the stock camera to pc cable, that's all I have. The cable shouldn't affect the individual files though should it?

blogs,

How are you exporting from DPP? Or does it fail to even open in DPP?

You spent a lot of money on a camera, why are you using it as a card reader?

Buy a card reader and save the camera for photography.

Heath,

Hes not alone. I'm another who prefers to upload direct from camera. Its not a crime.

I never said it was a crime, not sure why you jumped to that conclusion.

It's using a piece of $3,500 piece of equipment to do the job of a $40 piece of equipment. It's also slower.

Why do you prefer this method?

Heath,

Meant nothing by it, sorry if it upset you. But card readers have problems I have decided to simply bypass.

Everything has problems, nothing is perfect. After the data flows into the usb cable it should make no difference where it came from, but my experience has been that there are fewer problems with card readers.

Elie,

Lets just say we differ. I've had no problems with direct from camera but card readers have been problematic "in the extreme".

But I'm more interested in hearing more of blogs problem and seeing if we cannot help sort it out.

I strongly doubt that it is an electrical problem with the camera but we can't discount it entirely. Based on your responses I strongly suspect that formatting the CF card will resolve the problem permanently. Raw files are quite a bit larger then the jpgs extracted from them. I suspect what you are seeing is just related to the volume of data being saved. The larger the volume in a file the higher the probability of a communication failure.
I have both a card reader and a USB cable that I use for downloading the data to my PC? Both should work equally well. The card reader is probably a bit faster but the down side is that you have to handle the cards more, which in the case of a CF card could increase the possibility of bending a pin.
Someone brought up the fact that a USB cable directly connected to the PC may be more efficient from a signal strength perspective than going through an unpowered hub. I agree that the shorter route is probably better especially if you are doing problem determination. Also, a marginal cable might affect the quality of the signal so if you are still seeing some problems try reseating the plugs or swapping the cable.

Let us know how it turns out.
