This post is more about the A1 low-light focus than the photo shown.
I was shooting subjects at an airport museum on Sunday. It turned dark and I packed-up to leave. While walking out, I noticed a gal sitting on a military C47 wing. I set my strobe light-stand down, facing her, and with the A1 up to my eyes I was shocked to see the Eye Focus box on a completely black field (she was nearly in the dark without the camera). I took the shot, thinking it was a waste of time. When I got home, I couldn't believe the shot was in perfect focus, as were previous shots taken in extremely low light.
I am used to shooting the A7RIV with its -3EV spec vs the A1 at -4EV (spec's are usually at f1.4, whereas, I shot at f2.5). In general shooting, between the focus system improvement for Eye Focus and the low-light capability, I find the A1 to be incredible compared to any camera I have shot in the past.
I generally do not care for shots taken in the dark with flash, and this shot is no exception, so I do not really like it very much (I added a sky, since it was black in the original shot), but show it, below, to illustrate the A1 performance.
Another note - I normally shoot fast primes for these shoots and thought I would try the new Tamron 35-150 f2-f2.8 for '_hits and giggles'. I was fairly amazed by the great optical performance of this lens.
