A74 and a7r5 anyway to limit shutter speed to 1/4000 during efcs?

p.1 #1 · p.1 #1 · A74 and a7r5 anyway to limit shutter speed to 1/4000 during efcs?

I shoot at aperture mode most of the time with efcs on. I need to remember to turn it off when it gets too bright and shutter speed goes too high.

Is there anyway to limit the shutter speed so I get visual feedback of overexposure when it gets too bright. I just forget to turn it off and the bokeh degradation is not obvious on the tiny lcd screen. Or is there any way to remind yourself to turn off efcs?

Honestly, it is such a simple firmware fix. I am not even asking auto turning off efcs when shutter speed gets too high as that might have technical challenges in switching shutter on the fly in dynamic lighting conditions. Just let me set a max shutter speed in aperture priority mode…..

I wish they gimp the efcs max shutter to 1/4000 like a7c series….

Sorry, I know it doesn't answer your question, but why not use full mech?

All the time? The shutter lag with full mechanical is longer and the camera is much more noisier and more vibrations, esp when u shoot burst.

Once u get used to efcs, u prefer it to full mechanical. I program efcs onto my mode dial so it’s very fast to turn on and off. I just need to freaking remember it,

I don't remember any difference between EFCS and full mech when it comes to shutter lag, but maybe I didn't check it in detail. The noise is IMHO already there with EFCS and vibrations are not an issue when shooting at 1/8000s.
So, yes - it has its downsides but EFCS bokeh drives me crazy. I often wonder how I'd shoot if I were to get A7RV

Unless you are shooting fast moving subjects why not just use full electronic shutter

I tried using e-shutter on my a7RV, but the sensor read-out is so slow, I just keep using mechanical shutter instead.

That’s what I do. Anything that doesn’t move is full e-shutter. The speed of the readout doesn’t matter.

I thought you are suggesting to shoot efcs off ALL the time? The vibrations will kick in at slower shutter speeds.

A7r5 eshutter is really slow, then I have to rem to turn off eshutter indoors or moving subjects. I think that is even more frequent… efcs has much more use cases than eshutter… efcs only “fails” with shutter above 1/4000. That is part of the problem. Efcs works like 95% of the time so when the 5% hits, I forget to turn it off…..

There are reports that camera movement might introduce distortion for a7r5, the scan speed is 1/10 secs so you are like handholding to 1/10 secs so telephoto shots might get impacted. Never tested this though.

To answer your question, no. Not possible. Been a known thing for a while, been a known complaint for a while, don't hold your breath.

Yes, they should make a firmware option to allow automatic EFCS past a specified shutter speed.

I'm finding that if 1/60 or 1/125 SS would be enough to stop motion for a sharp shot, then using ES works fine with the slow a7cr scan speed. The 1/10 scan speed is not like 1/10 shutter speed. A9 is 1/160 scan and there's no issue stopping things requiring extremely fast SS. I'm not entirely sure how the relationship works.

It should be a simple software fix. Crazy it hasn't been done yet.

Yes, you're right. I'm not sure how serious shutter shock is with current gen cameras as I've only heard horror stories from the 1st gen

.
Anyways, there is no perfect solution unfortunately. One way to quickly switch between fully electronic and EFCS *or* full mechanical is to set a button as silent mode switcher. Then it's a one touch operation at the expense of not being able to differentiate between EFCS and full mech.

The problem is people are requesting automatic efcs past a specified shutter speed which is much more difficult to do as the shutter speed can dither at the threshold. Turning on and off efcs dynamically is not trivial.

What I want is much more simpler. Just limit allow the user to limit max shutter speed to 1/4000 when efcs is on. This should be like a 1 day work kind of thing….

It is not exactly like shutter speed but I think the distortion appears like rolling shutter. I have never tested this though and it might not be obvious unless you have straight lines in your frame.
