Quote:Not even that is true. CD AF cameras don't close down the aperture either when focussing, so focus shifts still can occur.
No Canon DSLR has a similar shutter slap issue.
The full electronic shutter often comes with rolling shutter effect. That is why they still offer mechanical shutters.
Yeah and I like OVFs for very good reasons also.
Some mirrorless cameras do close the aperture prior of obtaining the focus (depending on the light conditions). Some don't, yes.
Canon DSLRs have a soft shutter slap, yes, but there's a reason why I do the MTF tests on the 5Ds R in live view mode (the mirror slap).
A rolling shutter effect occurs with fast moving objects only. Now I'm not into action photography and in all those years I have seen this once (a speed boat). If action photography is your thing then yes, don't use a full electronic shutter. Electronic shutter should also not be used in artificial light (first curtain electronic shutter is fine). Even so - this statement is just a snapshot in time. Global shutters will solve this issue within a few years. The Blackmagic MFT camera has a global shutter till 1080p already.
