How do I get Canon EOS 5D Mark II RAW files using a USB cable and bypassing the EOS utility?
I had my CF card reader die on me a few times (i.e., it suddenly stopped working: instead of being recognised, and then allowing me to access the CF card, it was "cycling", i.e., appearing/disappearing from Windows). So I decided to do a backup using an USB cable.
My PC had [historically] the EOS utility installed
For personal reasons (mostly: special workflow, and avoiding the clumsy download interface) I wanted to just copy the files over, bypassing the EOS utility
However, when plugging the USB cable between the 5DMkII and the PC, it only got recognised as the camera, and when exploring that I could see each image twice in JPEG (one with extension, the other without, but both JPEG, whereas I know that on the CF one is .JPG, and the other .CR2, larger and with more details). I tried, however, to copy both, each in separate directories (as they had the same name), but it really ended up as two identical files each time, as if it "hides" the raw and instead shows another instance of the associated JPEG file.
Example: using a CF reader I would get IMG_0001.JPG and IMG_0001.CR2, the 2nd raw and much larger in details and size. Via cable I saw "IMG_0001" and "IMG_0001.JPG", both ending up as "IMG_0001.JPG" on my computer, and no raw file...
How can I retrieve the .CR2 files? (if possible, without uninstalling the EOS utility! But still bypassing it... I.e., how do I use a USB cable to access the files as if by a card reader?) (Should I boot on some linux boot CD and try from there?)
It is a different camera but the issue is exactly the same with all Canon DSLRs.
can someone remove the "This question already has an answer here : ...." ? as it is NOT the case (my computer IS recognising my camera. But the issue is that it allows only to retrieve the JPEG and not the RAW.)
Your best bet at this point is to re-ask the question. And if you are just trying to copy files from card to a computer, then it's really not much of a photography question and you'll get better, specialized help from a site like superuser. Are you on a Mac or PC?
@jrista: both pc and mac (usually, pc, but it could happen that the only available machine is mac). I could have a linux utility on a boot cd and use it on "any" machine, however...
@Oliver: So, you are saying you have the exact same problem on both your mac and your PC? Seems really strange to me. Personally, if I plug my 7D into my PC, I can browse the memory card plugged into the camera as if it was plugged into a normal card reader, copy files off of it, etc.
@jrista: i was saying i want a solution that allows me to work on any pc/mac I have to work with without changing my workflow. Hence, no EOS utility [which I could *not* install anyway on most of the computers i work with, as they are not mine to tinker with]. But for my information: on your mac do you see both JPG *and* .CR2 files? on windows you see each JPG twice and no .CR2
First of all, I always recommend a card reader instead of a direct USB connection. It will be faster, you don't need special software, and it doesn't use your battery while downloading. I prefer the current USB 3.0 readers but many options exist.
This looks like what you are looking for:
- GNU Canon Camera Utilities - http://canoncam.sourceforge.net/
I wish I could tell you more about it here but I don't understand much of what the linked to website says.
This forum seems to have an answer:
- "Get gphoto2 from the repos." - http://ubuntuforums.org/showthread.php?t=1622433
Overall I think that the EOS Utility is really the way to go for direct USB transfers. The other options seem to be either complex, incomplete, or non-existent. Beyond that, I would advise picking up a USB card reader as they are typically much faster and also don't drain your battery.
@dulac sounds like it is time to buy a better card reader. I've never had a reader die on me despite heavy use and lots of transport.
I prefer using EOS Utility for the sorting/file renaming capabilities it has as the pictures are transferred. But you are correct that you need additional code to transfer files directly from a Canon DSLR as Canon does not allow them to be used as mass storage devices. +1 for the links.
Thanks a lot, i'll have a look at those asap. (I'll then come back here to assign the checkmark to the correct answer, possibly this one)!
@AJHenderson: i'd be glad to hear of some good reliable makes (for CF + sd cards) ^^ I bought mine in a "normal" (ie, non-specialized) shop, and it seemed to work fine for a few months. The same model died twice on me already (for no good reason: it was always indoors, never travelled, no incident, etc.)
dpolitt: at first view the 1st link is probably right. And thanks for pointing out the 2nd as well (well sighted! ^^ ). I'll check that "gphoto2" linux utility too. If any of those 2 solution work, it'll be easy for me to create a bootable linux CD with them on, so I could use on (almost) any computer if the need arise. I'll post about this in a few days (can't test right now, but will try over the week-end)
@MichaelClark: i'm trying to be "eos utility" independant for several reasons. one of them is that I am not always on the same machine, and I don't always want my photos deliverred to the same directories... having the EOS utility in the middle is a big hindrance (I can't always install it, and I can always use it even on my "main" machine, or if i do i then have to move the files over to another destination and/or drive anyway).
@OlivierDulac - This Lexar reader is my current portable reader and it works great. It supports USB3 but should still work ok on a USB2 port, it just won't go as fast. It lives in my camera bag and has been attacked by my cats on multiple occasions when it had been left out and still is going strong and fast.
@AJHenderson: oh my... that's exactly the model that already "died" on me twice : no longer recognised by my computer (and by another computer as well) after a few months (it 'cycles' when plugged-in : "'be-BOP' ... (drives shows up)... (drives disappear) ... 'BE-bop' ..." (and on, and on, and on... every few seconds). I didn't throw the 2nd one out, thinking it could be some "silly" thing [dirt? cable? drivers?]
@OlivierDulac - interesting. Not sure why your computer is eating them then, cause that's a reliable unit from my experience. Maybe you've just had really really bad luck. I don't know.
@AJHenderson: i'll check on "yet another computer" to see if i haven't got a problem of driver on both computers i tried it on... seems rather strange as well (that's why i kept that 2nd unit, as it's a rather low probability that 2 died on me)
@OlivierDulac Are you aware you can change the destination folder with EOS Utility before importing photos each time? You can even have it create a new folder with whatever name and location you desire. It seems the simplest solution to me. You can also install it without a disc from this link: http://www.usa.canon.com/cusa/support/consumer/eos_slr_camera_systems/eos_digital_slr_cameras/eos_5d_mark_ii#DriversAndSoftware Select your OS, click on 'Software', then select 'EOS Digital Solution Disk Software 28.2A for Windows (For users who cannot use the bundled CD)'.
@Michael: yes, I was citing that thing as *one* of many reasons I can't always use eos Utility : the others: someone else's (or even some company's) computer, etc. I could usually reboot on a live CD for those, but NOT install any eos utility. Thanks for the info though (especially the link)
