I just returned from my Studio flash / strobe photography session, my first one after 3 years photography without Studio-work. Until back than, I worked with Canon and my Elinchrom RX flashes. But since about three years I switched to Sony A7R II and now also A7R III. So I was very apprehensive for this short notice mandate with actors to photograph within short time in improvised studio - with flashes. I dived into the menu to disengage this and that - quite happy of myself lol..-

But two things just make me feel utterly lost, I don't find the rational explanation ..jet :

1)

I had my A7R III dial on M (not M1,2 or3, nor P,S,... but on M.

I was UNABLE to set speed independently from Aperture. Understand that as soon as I closed say by a full aperture, speed would double, and not stay as should in M, say stay in 1/125, but would go down to 1/60. ( BTW : ASA set on 100. Not Auto-ISO.)

Since I could not waste any moor time to understand and remedy and because results where sufficient, I left it behave it that way. But It nags me to hell..

2)

Also: EVERY photo of this session, is in 3 copies -on the single SD-Card. Looks as if I had made verry fast bracketing in continuous light; with continuous numbering. Example : _DSC1520.ARW _DSC1521.ARW _DSC1523.ARW. All same size, same time, exact same image as same file 3 times.

When I made the photos, each photo was triggered once, the 4 flashes for this setup went of together once ( and needed a full second to recharge to be ready for next shot), NO WAY are they 3 separate triggerings. First I thought I imported them by mistake 3 times..whent back to see on SD card: they are there as described. What the f.. ?? lol

1) and 2 ) : NO JOKE ! I'm in a general stress and unable to think strait right know - but I feel better thinking I can unburden onto this community for getting the rational.. for later. Thank You for Your explanations !
 
Well, there has to be user error, cause this is definitely not how the camera operates. Probably some settings in the menus are seriously screwed up. I suggest you make a factory reset, which will set everything back to how it was when you received the camera new, then make a fresh start.

Good luck!

I know you are adamant you were in M, but it sounds like you were in P mode. That mode allows you to use the dials to favor exposure towards either shutter speed or aperture exactly as you describe, but M mode does not work that way at all. Maybe the dial marking for which one is currently selected is physically not correct on your body. Use the Fn button to look and see if one of the function menu squares shows a big M.

There is a continuous bracketing mode under the drive mode selection of the Fn menu. Make sure single shooting is selected. It could also just be continuous shooting with a fast enough rate that what feels like a single press is bursting 3 images every time.

Hopefully you can get it sorted out and I will help out if you have more questions.
 
I had something similar in Aperture Priority mode on my A6000

I shoot houses for a living (Real estate). i noticed last week my A6000 would not go slower than 1/60th sec in A mode with my new Godox X-Pro trigger. As the the scene got brighter it went up to sync speed 1/160 but I couldn't get it to go slower than 1/60th even with exposure compensation. I changed the flash mode to "slow" and that cured it. In M i could choose any shutter speed I wanted upto the sync speed.

Still learning coming from Canon.

You were probably using a lens of focal length around 50mm or less that the camera figured 1/60 would ensure a shake-free exposure and it knew from TTL that it could fill any ambient light lost from the faster speed. It felt no need to go slower than 1/60 because you were using flash. You might have found that if you were using a longer lens it would have picked a faster shutter speed to not go lower than because it would rely on flash increase its power as necessary.

If you were on a tripod for the scene, I recommend using Manual. Turning off SteadyShot might disable the shutter speed lock by FL, but I am not certain about that.

I starter this thread. I will come back here with some more precise input later when I'll have again my camera in hand.

I'm sorry : To point 2) It was indeed bracketing,! . .set accidentally, but not exposure bracketing. I presume DRO (and I dont have a camera at hand. Probably DRO bracketing (possible?) . If indeed DRO; As I shot only RAW (as "always") the Images are indeed indistinguishable, of each shot 3 identical photos.

And to point 1):

regarding M behaving like P it might get explainable (?) if I tell the hole story (witch I found irrelevant): I triggered the Elinchrom flashes with a Cobra flash on camera (Godox 860 II on manual, small power output - because my pocketwizard equipment produced black images - I presumed sync problem (canon settings) or other problems I felt I had to time to waste about on duty..). I wanted 1/200 or 1\250 but it kept going to 1\125, and was forced to 1\60 when I had to go from f8 to 11. I had set camera to ("simply strait") flash mode.

" Aha ! " ?
