Subject says it all - would like to use my R10 with flash, using focus bracketing/stacking, so should I be chosing mechanical or electronic shutter? And, how does the flash keep up withe the incremental bracketing shots? Many thanks in advance for your valued information!
Cant test since i don't have an R series camera, But If the feature is automating the focus and the capture of images, that would depend on the time between shots. I can't imagine the feature waits long enough to cycle and charge the flash between each shot, and the canon article almost says as much saying for creative lighting and focus staking you will need to use manual focus stacking. https://www.canon-europe.com/get-inspired/tips-and-techniques/focus-stacking-beginners/
