Electronic or mechanical shutter? Locked

I almost exclusively use EFCS. 14 bit raws and no rolling shutter artefacts. Sometimes I'll full mechanical shutter when I shoot wide open in bright light to avoid the weird bokeh issues you get in those situations with EFCS. I only use electronic shutter if I need to be silent which is extremely rare.

What body you shoot with? I use electronic on the r3 and don't see bokeh artifacts, but now I wonder if mechanical would do it better. Who knows, the bokeh looks good tho!

Mechanical is only a hair faster than the ES readout on the R3. I saw a chart on it, they are virtually identical on the R3. The same isn’t true for non-Stacked Canons though.

The difference is much smaller than with the other cameras, but more than "a hair", I think. Just 50% faster could result in a lot less visible motion distortion in some cases. Has anyone accurately measured the two rolling speeds? I thought I had some LEDs in the house that strobed much faster than 120Hz, but alas, I haven't found any; they are either all continuous, or 120Hz. You need something faster to measure rolling shutters faster than about 25ms. It would be nice to have a bulb that is bright and calibrated for a 1000Hz pulse, as this could be used to measure all current rolling shutter speeds.

Now base ISO DR is different on ES on the R3, but not enough to warrant using mechanical, except, in mission critical DR usage. To say, virtually never.

Now on non-R3 bodies? EFCS is your friend under 1/200, and mechanical is your friend over 1/200. Period.

Are you going by bokeh changes with EFCS there, or shutter speed concerns? I don't think that EFCS bokeh effects kick in visibly anywhere near 1/200, and they are only an issue with very fast f-ratios. Someone with an f/4 telephoto or slower, for example, should never worry about EFCS bokeh, and EFCS's lower shock is always preferable. I rarely use full mechanical, because I rarely expect potential bokeh effects.

I hope Canon brings stacked CMOS to the masses to solve stuff like this.

Without increasing visible read noise, which seems to be the Achilles' heel of current stacked sensors; they never have class-leading visible read noise.

5.5 vs 4. It’s a hair.

Now you’re splitting hairs.
