I am actually not a "new" alpha forum" user as system indicates.  Another topic, another day.

I have my camera set up on the memory settings 1, 2 and 3 for Portrait, Action and Landscape.  However if I change mode to "A" or "S" or "M" the shutter does not release.  It releases just fine on memory 1, 2 and 3 though.  Any clues?

I don't know exactly how you have set things up, but on my camera (NOT yours) if I switch from MEMORY 1, 2 or 3 back to P, A, S, or M, the camera reverts back to what it was last set at when I was in that MODE.

Something tells me you are referring to a different set-up.

I did figure out the problem and it is somewhat embarrassing to admit.  I had the camera set on "silent" so when I believed it was not taking a picture, it certainly was.  No issue now.  Thanks for your response.

    • ISO 320 is the A7R5's second base ISO setting. You will find at ISO 320 you will get better results than even ISO 200. I normally take a set of shots at 1600, 3200 and 6400 ISO. I am taking 60 light frames and 10 dark frames. I don't do any adjustments to the files before stacking. I really need to get organised and do some bias frames now. Here is pretty much my first successful Milky Way shot from a few months ago. I was combatting a bit of ambient light and quite a lot of cloud but I'm pretty happy with this. It was shot using my Sigma 16-28 f2.8 which is better at astro than I had anticipated, at ISO 1600.

    • Thanks for the information. Since my original post, I did some "experiments" at different iso settings. Best results were obtained at iso 320, and then increasing the exposure by four stops in Lightroom. The biggest difference compared to using a higher iso was that there was detail in dark foreground areas, while at high iso the dark areas were blocked. This is consistent with articles I've read about ISO invariance.
    • I do a bit of astro photography and do a lot of research etc. on best settings to use. I have never heard of anyone using ISO bracketing! Typically, higher ISO settings such as 1600, 3200 or 6400 are used and multiple light and dark frames are stacked to reduce noise. If you are worried about noise in dark foreground areas then just use a seperate exposure for them then blend the exposures in post processing. By the way, I also have an A7R5.
