I almost stopped using TCs at all with the A1/600GM. The IQ of the bare lens on the 50MPs is just unreal. I rarely used the bare lens on the A9II.

Very nice series, Laslo! I bet it took the cormorant quite a while to swallow that big fish!
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 don't understand it when people talk about the A1 having more noise than the A9. Surely, the A1 is at least as good as the A9. Doesn't the noise issue arise if you use the high resolution of the A1 to crop more? If so, it seems to me that you would never be worse off with an A1 over an A9.
Or am I missing something? Personally, I have not had any worse noise issues with the A1 in comparoison to the A9II.

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.
I'm finding more fine grain at higher ISO's compared to my A9ii , must admit though the A1's does pretty well for high MP's . I wouldn't want to push it over 6400 personally only unless very light cropping needed . I mainly use DxO PhotoLab with my A9ii usually light NR as standard. I'm waiting for DXO to update should be June apparently so should be more of a fair comparison . I've only just started with Photoshop

Which kind if pictures would you shoot in the "dark" / at the ISO's mentioned? If you want to I could go out and shoot some pictures and upload the RAWs for you in mentioned ISO range.
I don't ever do this (show pics without at least a little post processing), but just thought it would be entertaining at best. These are all shot very casually (just walking thru Garden World), resized only, no post processing, all hand-held, SOOC jpg's. Lens is a Zony 50mm 1.4 shot wide open, 100 ISO

Currently my lower light photos are all wildlife in shady, wooded areas using the 100-400 -- mainly birds, so I have to try and keep the shutter speed as high as possible. For example, I'll often drop the SS down to 1/400 or less (at f/5.6) just to keep the ISO under 10000, but much prefer a SS over 1/640 for birds and even that is often too slow.

Oh I’m more so asking because I have not gotten mine yet. So just looking for some feedback from all you guys. I just disagree with folks who say “if you downsample the image, it ends up being the same” yes maybe scientifically that holds water but I can prove that not to be true 9 time out of 10 in the real world. If the A1 is even with the A9 in the ISO department, that would exceed expectations for me.

50mp FF + 600mm is the sweet spot
