    1. So I did what I did last time, upgraded/downgraded five times and just bam, it suddenly works again. I cannot understand how this is possible, but it goes from havoc to Ronnie O’Sullivan precision with a few attempts.

      don't have context.. why did you upgrade/downgrade 5 times?

      worked fine first time with me. I have latest now, but sadly no reason at moment to get some pics
    6. The only thing I would love to se improved is that when I have "Focus priority to set to NONE" and I press the eyeEF custom button it won't find any EYE. It just presumes I want to focus one the EYE of the NONE subject or something :)))

      Glad it's sorted but just bare in mind, he's one of the best ever but Ronnie O'Sullivan can also be very unpredictable!

      Do you install via a cable from your computer or do you transfer to a SD or CFexpress card via a card reader?
    12. I did a couple of very quick tests, and it does seem the tracking ability is now on par with 1.4.0. I'll be able to tell for sure over the next week or so.
      I'd love to hear your experience. I downgraded mine to 1.4 and I'm cautious about upgrading at this point in the middle of senior portrait season....

      The AF was chaos, the AF point jumps around and it tracks worse than the 1d3, before any of the fixes that didn’t do much. It won’t show the head or body square/rectangle, only a cluster of points.

      I’ve tried both, but use mostly a card reader and I’ve tried both cards, makes no difference. And for both 1.5.1 and 1.5.2 I did the same exact routine 5(6) times and then suddenly my the tracking box comes down and sits very stable and accurate. It tries it very best at tracking whereas before it’s all over the place and nothing is in focus.

      Card readers are variable in quality and performance. I consider it safer and more reliable to slot an SD card into my Mac, drag the FIR file to the card, eject the card properly, and then put the card in the camera. I also follow Canon's recommendation to remove the lens from the camera, and install a freshly charged battery before updating. I wonder if some of the problems people encounter are caused by using different methods to update firmware.

      Incidentally, my R5 running on v1.5 clocked up another 5000 actuations last week in Peru, where it was subjected to extreme humidity, frequent showers and high temperatures. It froze once, requiring a reboot. I also had some inexplicably bright flickering in the EVF when half-pressing the shutter button after a few hours of heavy use, although this issue disappeared once the camera cooled down. I was shooting entirely stills, and had no overheat warnings.

      My MacBook Pro doesn’t have a built in card reader, and I have never had an external card reader let me down. The instructions with the firmware upgrade don’t tell you to remove the lens. I prefer to transfer by card rather than cable because cable connections occasionally let me down.

      My R5 has that bright flickering as well with the half shutter press when focusing on something that’s not brightly lit like indoors or shadows. I took to the Canon Center in Santa Ana and they couldn’t find any issues but it persists. I got the front desk person to witness the issue when I showed him, but when he took it to the tech in back the tech couldn’t replicate the issue. It doesn’t affect the captured image in anyway but it is annoying and distracting when composing a shot.

      I also see the same flickering phenomenon in the lcd screen as well, not just the evf.
      if anyone has a solution I’d love to know.
