DSLR resolution suffers by about 20% when electronic shutter not used with mirror up
In article .com,
Savageduck says... The solution is simple; Go mirrorless! With the E-M1 II in high res mode (80 MP) it's not sufficient to disable the mechanical shutter (i.e. use the electronic shutter). You need a wireless shutter release and you also have to disable the autofocus, because the AF motor movements in the lens generate vibrations. -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

Electronic shutter - check! Wireless shutter release - check! Manual focus with peak focusing - check! As long as that pesky flapping mirror is not an issue the problem is solved. Unless of course you have chosen to stick with a DSLR. -- Regards, Savageduck |

Unless of course you have chosen to stick with a DSLR. Still no problem with my D750. Select Mup (mirror up) - select. No electronic shutter. See note below. Wireless shutter release - check Focus peaking (of a kind) - check. See https://www.dpreview.com/forums/post/57292217 Heavy! Vibrate it if you can - check. Note: I'm not keen on electronic shutters. They can lead to image distortion with action shots and they are reputed to shorten the life of the sensor. -- Regards, Eric Stevens |

Unless of course you have chosen to stick with a DSLR. Still no problem with my D750. Select Mup (mirror up) - select. Live View in action. No electronic shutter. See note below. Noted. Wireless shutter release - check Good. Focus peaking (of a kind) - check. See https://www.dpreview.com/forums/post/57292217 Close, but not quite as effective, and useful as true focus peaking. However, for the type of shot that all of this procedure is intended for you would be using Live View, and it should be good enough. Heavy! Vibrate it if you can - check. Always possible. Note, this discussion brought on us by Rich, and the geeky article he discovered, is going to be a minimal issue for those photographers with the appropriate knowledge, and skills regardless of the camera type in use. The results of any minimal vibration is going to need some serious pixel-peeking to detect. Note: I'm not keen on electronic shutters. They can lead to image distortion with action shots and they are reputed to shorten the life of the sensor. Electronic shutters have their place, and provide an option over a mechanical shutter. However, as you have noted, when it comes to action shots where the shutter speed has been pushed, rolling shutter effect comes into play with all the unwanted distortion that brings. Though there are times those effects can be amusing. For the type of shot where the camera is tripod mounted, the subject is static, and vibration is to be minimized, the electronic shutter can be appreciated. -- Regards, Savageduck |
