5D Mark IV Freezing up

[iris]

I received a brand new 5D MarkIV from my husband for Christmas...I've enjoyed using the full frame camera and lenses I've collected over the years that rightfullly should be on a full frame camera...

Several days ago while shooting and an event, the Camera FROZE..I mean suddenly the AF for the lens was dead and dark..the LD screen on the back was lit up and frozen with the camera setting sitting there..I tried to simply turn it all off an the on of switch had no effect.. After tryik several other buttons it became evident that EVERYTHing was frozen..So I treated it like a FROZEn computer screen, taking out the battery and sd card and waiting for a few moments, REinserted and all was well.  I totally forgot about it and treated it as a "One-off"    However, I was wrong..today it happened again..Very disturbing to have this kind of issue with such an expensive piece of equipment.

I have looke on YOu Tube and at various websites for answers..Apparently others have this problem...Any Answers that you Canon Pros know of??

What would you do?  Should I let Canon Fix It?  Should I insist on a new Camera?  YOu pros out there would you just ask to have your mony back?  NOt sure than can even happen?

Hi there,

my camera seems to work now, after the mainboard got replaced twice and the processor once, the dial assy once and some other things at the beginning stages. I handed it to the repairs 5 times over the course of 6 month (on repair warranty).

My camera kept freezing, even without any lens, with a canon lenses, with fully charged canon batteries or cheaper ones. I don't think it had anything to do with the freezing issue. At the beginning stages I managed to get the camera work again by changing batteries, by switching the camera on and off multiple times, by changing the memory card and by switching from video to image mode back and forth. But after a short amount of time the problem recurred until the camera stayed frozen and I had to hand it back to the repairs.

The battery was non canon. When I first got the camera i had an older tameron lens... went up to the canon service center with it and the camera and was told to get the newer tameron lens because the firmware on the older lens wasn’t supported-so we purchased the new model. No issues all season with it. I’m thinking it’s the battery and am going to change it out. Next step is going back up to the center.

I started having this problem when I added a Canon F4 L 70-200 to my collection, The body worked perfectly before that for years.  A few days before the freezing started, I also put on and used a Canon Flash for the first time.  No freezing occured then, but...  I also just upgraded to the latest firmware.  I have to think it is one of these three changes.  My bet is the firmware...
