    hi

    My R6 with RF 70-200 2.8 sometimes does not save all images of burst in H+ mode raw+jpg to card; 1/200, 2.8.4000
    this happens shooting in theatre with strong contrast, subject is in theatre light, background dark

    when testing at home the complete burst of 10+ images is saved

    when shooting in theatre I only get 2-3 images saved

    advise anyone?

    thank you

    Well, your shooting well slower than your recommended 1/1000 of a second shutter speed to maintain the high burst rate.
    https://support.usa.canon.com/kb/index?page=content&id=ART177866

    The Takeaway from the Canon KB there is that with really fast shutter, and the electronic curtain, you can burst up to 12 in ideal conditions.
    Low lighting will bring settings that slow it down and drop it to as slow as 3 frames per second. This is a camera speed to write issue not the lens. You have a lens perfectly matched to the camera, even the EF equivalent supports 12 frames a second in ideal lighting

    thank you!
    I did read the manual on this
    sorry, but I dont understand why the same manual settings do not work in the theatre and give good results at home
    since I save raw+jpg. is it the time needed for jpg different? does shooting in raw only help?
    or maybe different focus settings eg no continuous focussing?

    low light will take more to write to card.
    Slower shutter will also impact the burst spreed, as you can see the recommended at minimum 1/1000, you were at 1/200. They said with a mechanical shutter its limited to 6 shots per second. Your not going to get 12/sec burst indoors with that lighting trust me.

    yes , I understand low light will take more time, but why?
    Yes, I was slower 1/200 but why does this setting work ok in my home environment?
    trying to find a solution: no noise reduction maybe?

    I think you could pretty easily setup the example at home and compare the settings between the two sets of images to see what is different.

    If you want technical reasons why the shutter should be be 1/1000, or how noise, iso etc,,, all balance in to the time it takes the camera to write the image to a card you would have to ask a engineer at canon, all i can say is that 12 frames per second is a lot for the camera to capture in optimal lighting with a really high shutter speed. My 5d mark 4 is only capable of 7 in optimal conditions and the mark 3 before that was 3.9, the mirror-less bodies have unlocked some faster fps without the mirror but are still held to how fast they can record the data, there is only so much buffer for the camera to work with before its capturing data faster than it has ability to hold it.

    I also am not exactly sure what the use case in a theater is for bursting so many images. I rarely burst more than 2 or 3 images unless i am trying to freeze a very fast moving subject, but hey I cam from film where i have to focus manually as well and do focus traps and manually advance the film between each shot :D.

    thank you

    The technical thing would be the write to card time but I thought the buffer in de camera would be big enough, not
    I have been taking pics a long time, like 45 years and know its a luxury problem now

    the reason I would like the burst is because our musicians and actors change facial expression very fast, capturing it with single shot is almost impossible for me; the same in shoots outside but there I have the burst, usually the 2-3 frame is the one I like

    I disabled some things in the menu like noisecorrection and bought some wine for the lighting guy :) now I get better results

    thanx for all help
