Mirrorless cameras (Page 7): As far as I know, no company has a global shutter yet - every camera takes several operations to read its sensor

I think it is important to note that using fast burst mode puts a lot of strain on the shutter mechanism. The battery grip only boosts the mechanical shutter burst speed. There is also an electronic shutter that places NO wear on the mechanical shutter and can operate much faster than the mechanical shutter even without the grip, and probably should be used for burst mode instead of the mechanical shutter.

As far as I know, no company has a global shutter yet - every camera takes several operations to read its sensor - and as a result motion can cause distortions when using "electronic shutter"only.

Adams did use a “small format camera” a Hasselblad. There is a book of his color photos too. Somewhere ther is a photo of him using a Leica. An old photo, because he has black hair!

Thanks for that info. I just read up on that. The only potential problems would be rolling shutter, with the attendant distortions shooting fast moving subjects, potential light flicker with the basketball gym lighting, and the fact that flash is disabled (not that it's an issue in burst mode). Still, I'll use that when I want silent shooting, or burst mode with slow-moving or stationary subjects. Quite honestly, I was wondering where the "silent" shooting mode was! You've helped me to find it.

I am only quoting what Fuji advises about their electronic shutter which operates at 14fps. The mechanical shutter can do 8fps without the battery grip, and 10 fps with it. There are no reports from Fuji that I am aware of regarding distortion with the electronic shutter. It is fairly obvious though, that continuous operation of a shutter at 10fps will shorten its life. The shutter mechanism is one of the last vestiges of the purely mechanical SLR, and with the electronic shutter we now have an almost completely electronic beastie!

I will try the electronic shutter with my pups - nothing is faster moving that a 3 month old puppy, and let you know what kind of distortion I get!

rolling shutter issues is what you'd need to look up for electronic shutter problems.

From a review site:
"Rolling shutter looks well controlled in full HD 50/60p, but average in 4K 24p. To be checked in our lab test soon."

From personal experience mirrrorless are very good for general purpose photography and not so good where fast, accurate autofocus for fast moving subjects is required.

I don't know about other cameras, but Sony is fast and accurate. The mid-level cameras are 10 frames/sec with focus tracking. Don't think that mid-range DSLR's are that fast.
