Cant transfer photos with iso6400 and above from eos M?

Hello...

When using my Eos M im having a strange issue, which I first thought was memorycard related but it isnt. (tried several)

It seems when using iso6400 and above when taking photos I cant seem to transfer them to my computer using the supplied usb cable. The photos look fine on the camera and the transfer works perfectly when I use a standard cardreader to my computer. All photos with iso3200 or lower transfers perfectly using usb cable.

Is this a known issue? Am I missing something? Tried searching but nothing came up.

best regards

I cant see how one this has a connection to the other. thats interesting. I wonder if its an isolated incident.

The only thing I can think of is that high iso photos are larger in size, around 26-27mb for iso6400 and aobve 32mb for iso12800. But I cant see why that would be an issue.

Tried 3 memorycards, sdhc 8gb (30mb/s), sdxc 64gb (30m/s) and 32gb sdhc i extreme pro (95mb/s), same problem with all of them.

Even tried 2 different usbcables. Same problem.

Even tried all usb-ports... No difference

Have you tried using different import program?

I vaguely remember something about someone having issues with transferring large file and I'm pretty sure it had to do with from camera. Since I can't remember the details it may not have anything to do with your issue but the mention of the large files sizes did spark the memory.

Try a simple drag and drop, rather than importing via any softwares.

Or just remove the card from the camera and use a card reader (which is usually faster and more efficient, anyway).

I think that the PTP limit of 210 MB might be what I was remembering, so that shouldn't be the case for your files.

I did try dragging and dropping in both windows explorer and total commander... Same issue, the transfer just freezes.

The card reader works just fine, but only my laptop has a card reader. The problem still remains with every other computer I use, and the usb-cable is a pretty easy way to transfer files.

You may have the same problem I had a while back. My problem wasn't with high ISO shots, rather with raw images with lots of white or bright space, such as a shot of the sky - these files were large. All other images would transfer via card reader but the bright ones gave an error.

Turned out the card reader needed more current than the USB hub could supply. When I plugged the card reader directly into one of the computer's USB ports the problem was solved.

The USB spec says the maximum power from the computer's port is 500 mA, which amounts to 2.5 watts total. If a hub divides that three ways you can see the problem. Here's more than you want to know about USB power: http://www.ti.com/lit/​an/slyt118/slyt118.pdf

It seems to be a big file issue... Just tried importing a 148mb movie clip. Didnt work either.

Should I contact Canon about this ? Annoying issue.

Seems a software limitation. Did you try using the EOS Utility application?

What computer and OS are you using? It seems like this only occurs with a USB transfer, notorisly slow except for USBB 3.0. Are you allowing sufficient time for the transfer? omeone mentioned these files might be 27 mb. My first PC, 20 years ago only had a 40 MD hard drive.

Think about things, that PC likely doesn't know what the heck ISO was used, it only knows file size. Big files mean longer transfer times.

Downloaded Eos Utility now, and somehow it works ?! So there semes to be some software limitation, and using Eos utility solves it...

But still my problem remains, I would like to use Adobe Lightroom for imports directly. Strange...

Gonna try and update Lightroom and see what that does.

Well updating Lightroom didnt do anything...

Have you tried a different card reader?
