The one thing I haven’t seen yet are images during light fall off at high ISO’s. I was third on the list at my local camera store and they have only received two A1’s. It’s supposed to be here this week. I really rely on high ISO because I’m usually shooting in low light and many times just after sunset. The A9 excelled in this area. 6,400, 8,000, 10,000 ISO. Even sometimes higher if you ETTR correctly. The A9 is an incredible sensor among other things. This area would be a deal breaker for me. The only benefit I would be getting out of it otherwise would be the 120 4K. So I’m really hoping the noise performance is as good as the A9. Noise after sun down is different than noise in nicely lit frames.
I'm curious about noise as well since I often shoot in heavily wooded areas with relatively slow tele-zooms and usually hover between ISO 1600 and 10000. The A9 files clean up very well in DeNoise and from what I've seen and read the A1 has noise levels similar to the A7R4, which while not quite as good as the A9 can hopefully clean up as well. Being higher resolution, of course also brings benefits in terms of image detail and crop-ability, which IMO are big benefits over the A9 sensor, especially for wildlife photography. DR at higher ISOs is about a wash between the A1 and A9, although below 800 the A1 does a bit better, according to the measurements I've seen. I have an A1 on order but assume it'll be at least a month before it'll be in stock so I have a while to decide if I really want/need it.
It seems we've hit a point where we more or less know what the noise levels will be based on sensor resolution. I suspect the days of almost-magical noise and DR improvements with each new sensor are over. Read speed seems to be the new frontier.
