Many thanks for making the effort to test this, Bill! I suspected this to be the case.

Thank you BillTurning off the EFC appears to add just over 0.1 seconds of shutter lag.
It feels like enough to change the character of the shutter response from immediate to sit and wait.

Hi VivekHi Jono, First off, I thought Matt snapped a younger brother of yours! You need to change the current avatar! :lecture:
Unlikely to be over 0.1s or even 0.1s. The A7 claims 5fps burst rate. In the continuous mode, only the shot gun shutter works and the e-shutter is disabled.Turning off the EFC appears to add just over 0.1 seconds of shutter lag.

You are welcome.Thank you Bill
1/10th second is a long time if you're trying to catch a fleeting expression.
Disappointing I think. No A7R in my future.Many thanks for making the effort to test this, Bill! I suspected this to be the case.
Bill, I would love to. but have no clue how! i can test for UV or IR, something optical but no speeds, I am afraid.But it is.
Test one yourself and then respond.

I've no idea how you do it scientifically, but realistically I have a good method.Bill, I would love to. but have no clue how! i can test for UV or IR, something optical but no speeds, I am afraid.
is there a simple way that a lay person could do to check this?

Thanks for the tip. I was just going by the 10-20 test shots I've taken around the house since the camera will primarily be used indoors. It seemed like quite a bit was getting overexposed so now I have the histogram on permanently now. It seems to be reasonably accurate with expected output.Beware that impression: it regularly underexposes by between 1/2 and 1 2/3rds stops, it just has very paranoid blinkies. The sensor has, probably for processing pipeline issues, noisier shadows than a D800 so it is vital to expose more to the right than you'd think… as long as you are shooting RAW, that is...
I know I'm sounding dumb but where is the EFC setting? I can't seem to find it at all in the menu.Turning off the EFC appears to add just over 0.1 seconds of shutter lag.

It's only available on the A7, unfortunately.I know I'm sounding dumb but where is the EFC setting? I can't seem to find it at all in the menu.
There isn't one for you to find in your A7R. "EFC" here stands for electronic first shutter (available in NEX-6, 7, etc and the A7). No such abbreviation exists either.I know I'm sounding dumb but where is the EFC setting? I can't seem to find it at all in the menu.
Thanks but it will not work for me. I do not believe in your results either.I took shots of a running stopwatch with a 1/100 sec readout.
I tried to anticipate when the seconds digit would change. That way I account for my biological lag.
I also tried hitting the shutter the instant I saw the seconds digit change. That way I was adding my lag to the camera lag.
I alternated shots between Electronic First Shutter on and off so as to minimize any bias due to a learning effect.
After many images using both techniques I looked to see what time the stopwatch showed at the instant of exposure.
I won't claim I can get 0.01 second accuracy but it was very clear the Electronic First Shutter saves at least 0.1 seconds when in use. I believe it is a bit more than that.

Thanks, Jono. I have been shooting with the A7R and as explained in the previous posts, I do not have any lag at all. Coffee (any form) is my favorite drink.I've no idea how you do it scientifically, but realistically I have a good method.
Go to a bar with a doorway into a decently lit outdoors. Settle down with the drink of your choice (espresso is probably best to avoid person induced shutter lag).
Focus on a point 3 foot beyond the entrance and wait . . . when someone walks past - shoot. If they're in the picture, then the camera has decent shutter lag, if they aren't it doesn't.
I've done this with a number of cameras, and it's unnerving how few of them make the grade.
A straw poll of owners and would-be owners of the A7R:
Please state if you are
An owner (and for how long now)
Have ordered and not yet taken delivery
A prospective owner
and if you are bothered by:
Orange peel effect
Jaggies
Shutter sound
Shutter vibrations
Colour shading with native lenses if you have them and with non-native lenses if you have tried them.
I'll start, next post.

This is for real?! :shocked:Didn't realise till today, the camera lets you shoot without card, no way to switch that off? I did of course realise the hard way today, wasn't chimping till it was too late and then I notice the little orange writing 'no card' on the screen....
