Mirrorless, electronic and mechanical shutters
Mirrorless, electronic and mechanical shutters
Just getting around to getting my first Mirrorless camera (R6 II)
There are so many different pros and cons by the looks of it between the Electronic shutter (ES) Electric first curtain (EFC) and Mechanical shutter (MS)
Am I right in saying for fast jets/birds/landscapes to use the ES? And the MS for props/sports?
Just pondering others experience in using these.

Re: Mirrorless, electronic and mechanical shutters
The mechanical shutter allows the camera to capture 14 bit RAW files, while electronic only allows 12 bit. So for landscapes I'd absolutely keep it on mechanical shutter. As for jets and birds, I'd still use mechanical as much as possible. The newer cameras are really good in terms of avoiding rolling shutter, but you can still get hit with it while photographing anything that moves. That being said, if you're trying to get that perfect bird in flight shot, or a crossover pass at an airshow, the electronic shutter will likely suffice.
Re: Mirrorless, electronic and mechanical shutters
Ok so only use the electronic shutter for when you need the high fps
thanks EGDR

Re: Mirrorless, electronic and mechanical shutters
My experience so far - I'm pretty new to mirrorless equipment having recently purchased a R5 using the 100-500 lens. Spent a lot of time chatting to friends with similar equipment to take advantage of their experiences and to try different modes to see what worked (or didn't) for me. With regards to shutter modes I've taken to using EFCS as my default and having used the camera now for helicopters, props, fast jets, displays and also for wildlife. I see no apparent 'rolling shutter' effects and see no reason for me to change to any of the other modes, very happy with the camera and lens.
Good luck with the new camera, look forward to seeing some of your results.

Re: Mirrorless, electronic and mechanical shutters
Main thing to look out for with EFCS is if you're shooting at a wide aperture, the way the shutter curtain operates can sometimes make the out of focus areas, or bokeh, look a bit strange. This is because the electronic curtain and the mechanical curtain aren't exactly aligned. Mostly becomes apparent at very fast shutter speeds.
Re: Mirrorless, electronic and mechanical shutters
Thank you guys! Having only just had a quick play with it I think the main thing to be getting used to is actually the EVF! Those high frame rates are overkill aren’t they 
Re: Mirrorless, electronic and mechanical shutters
So after so experimenting the the ES works well however trying to pan with a moving subject using the MS is nearly impossible because there is so much lag in the viewfinder. Is there a setting to minimise this that anyone has found?
Re: Mirrorless, electronic and mechanical shutters
As per my post above re: EFC.
Re: Mirrorless, electronic and mechanical shutters
Will that not introduce rolling shutter on props? I’m sorry for probably daft questions but with this issue on these new mirrorless cameras is it now in practical to use a mechanical shutter on fast moving subjects like we have for years on DSLRs, because the EVF can’t keep up?
Re: Mirrorless, electronic and mechanical shutters
No apology needed, valid questions. Have a see for yourself; all three with the camera set for EFC; I'm more than happy with the results.DanSeaman wrote: ↑Sun Mar 02, 2025 2:50 amWill that not introduce rolling shutter on props?

Re: Mirrorless, electronic and mechanical shutters
EFCS definitely better than the MS but it was on the slower Civil stuff, I’m glad I’ve still got the old DSLR because that’s what i still Lean towards. It’s going to take a long time for me personally to get accustomed to this EVF! Be interested to hear about how you find it Deaves!

Re: Mirrorless, electronic and mechanical shutters
I love mine so far. A little bit of rolling shutter for panning shots but the ES will come into its own with airshow season. Fully transitioned to it as my main camera now and will keep my old one as backup or lens changing.DanSeaman wrote: ↑Sat Mar 15, 2025 10:14 pmEFCS definitely better than the MS but it was on the slower Civil stuff, I’m glad I’ve still got the old DSLR because that’s what i still Lean towards.
