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?
Freeze not every time, but often. I try many type of CF memory card, but problem persisting, no matter which card I use.
I take pictures using Live View more but using and VF. When camera freezing up not responding to LV button, nor I could take any picture, pressing the shutter button does nothing. Black lcd screen, top screen is fine. Turning the camera on/off does not help. The only solution is to remove and reinstall the battery.
I use my phone to shoot video of the lockup symptoms and send to Canon, but thay say noting more 😞
What exact setups are both shooters using when this problem occurs (RAW, JPG, or both recording, which card, dual card, etc)?
Memory cards can create lots of issues because the hardware/operating software doesn't always handle unexpected failures gracefully and a lockup can occur. Try a single known good card (either CF or SD but avoid micro cards plus adapter which inserts another potential failure variable). Get the card from B&H or a trusted local retailer, a lot of the stuff sold online including from the elephant sized etailer is counterfeit with memory (cards, USB sticks, etc.) being one of the most commonly counterfeited items available.
With a known good card also stress test the system by having it shoot RAW plus JPG in a sustained burst in high speed "drive" mode which loads the processors and battery system to their maximum.
Unfortunately Canon may have some glitch in the firmware not yet identified that creates a lockup under specific timing conditions and documenting as well as possible exactly what transpired in the few minutes prior to the lockup can speed the repair resolution for your camera and others. Canon service is generally rather exceptional so document the attempted repairs and problems so that once a resolution is identified your camera can be properly fixed. Use your phone or another camera to shoot video of the lockup symptoms before you clear it via battery removal to document the problem. It may help Canon to diagnose the issue, properly documents that it occurred (thus a time stamp for this video is useful), and it removes any doubt they may have about the customer is somehow imagining the problem.
All my lenses are Canon....the shoe flash is Canon Speedlite 430EXii....I had the flash on both times that my issue with the camera going dead occurred....I may have had the Canon Speedlite set to its highest power...I do pay more attention to that now...usually I've always left the setting at its highest point an adjusted brightness level more by adjusting and changing the angle of the flash rather than the power setting...
As I said I have no idea why I've had no issues since the camera went to Canon labs. The ony thing they said they did was download the latest firmware....I did throw out some suspect batteries....
One peculiar thing does happen fromm time to time.....the other day with flash attached...and shooting AP....I pressed the set button which I had moved a custom button function....instead of the button function showing DOF (which was a mistake on my part as DOF only shows on your back screen when you are in "live view"...which I was not) but anyway when I pushed the SET button where I was expecting incorrectly to see DOF through the view finder, I hearda electical crackling noises....the camera definitely did not like what I had just done!! When I did it again...same result "loud electrical Crackling".....Could our issues with the camera suddenly shutting down have something to do with a combination of custom button functions and battery or circuit overload....I"m no engineer....that's for Canon to figure out...I'm just grateful that my issues sseem to be over...
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.
