Camera functions not responding fixed

My EOS R5 lost several functions today including loss of all menus for camera settings and playback, loss of mode functions, loss of auto focus, loss of metering, no shutter operation. I was able to take pictures in manual focus mode but could not review them in camera. Contacted support on the phone but because I could not access any menus, we could not reset camera or update firmware. Attempted to reset camera by removing battery, turning on camera and pressing shutter button several times. Also, connecting to computer and using EOS utility showed the camera was "busy." Phone support prognosis was to send camera in for repair.

 

After leaving camera for several hours with no battery, I was able to change the mode and updated firmware using EOS Utility (Mode previously stuck in Tv and could not be changed). Now all camera functions have returned to normal.

 

NOTE: I had just installed a new SD card 64 GB, 150 MB/s before this problem occured. New firmware 1.3.0 is supposed to fix cameras not operating properly with certain SD cards. It's interesting that the camera continued acting poorly even when I removed the card when I was troubleshooting. In any event, I have posted this for information purposes only. The camera is now functioning normally after setting for several hrs and updating firmware.

Exactly what brand and model of caed are you using? Did you format the card in the camera? Is it a full size SD card or a micro SD card with an adapter? Did you buy the card at a local, reputable dealer (Best Buy for instance) or from Amazon or Ebay? There are some real problems with counterfeit memory cards sold by online dealers.

So I misread the details on 1.3.0 firmware. The issue apparently is with CF cards, not SD cards.

 

"

9. Fixes a phenomenon, in which, in rare instances, the camera does not function normally when using certain CFexpress cards."

The card I installed is a SanDisk Extreme 64GB purchased from Amazon vendor, Digital Media Source. Selling price was $15. 35. B&H selling them for $15.49 so competitively priced. I have to clarify now that the card had been in the camera for a while since the purchase date was 3/15/21 and has most likely been causing no issues. The card was formatted in the camera. I bought 4 cards and have 2 in a Fujifilm and one in a Leica. No issues with either of those cameras.

 

So this adds to the mystery of why the camera went bananas. It has been working fine since the update.

 

Could it have been a lens issue? Tried an EF lens with Canon adapter. No change.

Could the camera have gotten wet? I had been out in misty weather but the camera never got wet or rained on.

Checked card and is legit.

A more thorough test test of the card reveals a 64Gb with actual size of 59GB and write speeds of 64MB/s, read speeds around 56 MB/s. Card says max read speed of 150 GB. Used an app along the lines of what F3 does on Mac's called sdspeed.  Having never done this depth of checking before, I have no idea what these numbers reveal about the card's authenticity and whether or not these results would cause or contribute to the issues I had with the camera.

SD cards aren't always what they appear to be.

 

Member Ray-uk found this one about a year ago.

This sort of thing seems to be exlusively an issue with certain eBay or Amazon vendors. Though I doubt you'd get a card like this from B+H Photo.

You may have uncovered nothing of any significance.  The "actual size" is easily explained.  Some of the storage space is used as a directory, ot keep track of where stuff is stored.

 

When you performed the speed testing, did you use a device that was capable of 150 GB read speed?

Kind of what I thought. I got higher transfer rates with a different card reader. Don't think my SD cards are an issue.

You cannot rule them out, not just yet.  Did you try the tests I suggested yesterday afternoon, yet?

Yes. Let me clarify that the camera is working fine now and has been since my first post. When it was acting up, neither removing lens or memory card had any effect. Basic camera body would not display menus or allow mode changes. I imagine it may act up again, or not. Hard to fix it when it ain't broke.
