1DX lock up?

[Studio1930]

The pro shop that I buy all of my gear from doesn't sell Lexar Cards and has warned me against buying them for Canon cameras suggesting that Canon and Lexar have had issues in the past and that Canon doesn't officially support them. I have no idea what any of that means but I just buy SanDisk Extreme cards to be safe. I would love to hear if your problems stemmed from the cards as I'm extremely interested in the new Lexar 1000x cards. They seem like a better fit for the fast frame rates of my 1DX, but at ¥70,000 a pop in Japan, that's a huge investment to be wrong about.

I had Sandisk cards die on me in my 1 series cameras so I switched to Lexar 1000x 16 GB cards and have had no issues after 50K or so shots on a 1DX.

my 1Dx locked up as well when i started taking a few photo. i used the lexar 32 g 1000x. The LCD screen went black. all the buttons won't work. had to take out the battery and plug it back in and the camera was back to normal.

Thanks for the input Studio 1930. I'm definitely considering the switch to the faster Lexar cards.

As a note, the lock-up seen here has happened with both Lexar cards (me, 1000X cards) and SanDisk (Mark). Here's his post:

The red light was on for almost the entire shoot, I'm using Sandisk 64gb and 32gb Extreme Pro cards.

Seems the 32 GB LEXAR 1000x is at least a small factor in the lockups! maybe that's why they are ON sale at BH.

Maybe. Card I/O is asynchronous, I wouldn't expect it to lock up the camera. When I saw the issue, the shutter got stuck open. Thus, I wonder if perhaps the new shutter mechanism might have some quirks that haven't been fully worked out, or if maybe some of them have manufacture defects.

Just acquired my 1DX and it had a BAD charger first second right out of the box. Pain full 2 batteries and no juice had to wait a few days to get the Camera store to help me. So yeah i can see them shipping a bum camera shameful 7000$ and quirks, but its the market we live in.

Ran chkdsk /R /F from command prompt, and it found no errors. I also ran "error checking" (right click on drive, properties, tools, "error checking"). It, too, found no issues.

Hmm...

FYI flash is not like a hard drive and bad flash sectors are usually automatically remapped in the cf card's firmware so unless it's totally screwed a chkdsk /f /r /x won't help or let you know there's a problem. It's technically possible that it's still the card but i'd still suspect some camera bugs.

Thanks, exphose. I had also written a Perl script that copied large files to the card until it was filled. Didn't run into any issues with the card. That, of course, doesn't rule out weird interactions between the card and camera.

But I'll note that I've not seen the issue with the replacement 1DX I have (knock on wood) using the same cards I had before -- I've even filled them up during a shoot.
