Could you be more specific? Dynamic range measurements show differences of mostly a bit over a stop between the A1 and E-M1 III/X, very likely due to dual native ISO on the A1. So I'm curious where the second stop comes from.I use a Sony A1 and EM1X/iii. The Sony is 2 stops better up til iso 6400.
The A1 grain is different from the EM1 and looks that extra stop less in the lower ranges, When I was deciding on the A1, I downloaded dpreview raw samples, resized the A1 to the same crop and mp to the same as m43. Noise was about 2 stops to my eye. At iso 6400, m43 was better by a noticeable amount to the Sony iso 25600 and on par with it’s iso 12800.

With the ff iso12800 is about the same as iso 6400 on m43. There are other advantages and disadvantages to both systems in low light / higher iso. The Sony CAF is light years ahead, the Olympus ibis is in a league of it’s own.
View attachment 913264 This is simply not possible with m43
I'm curious to know why the above shot is simply not possible with m43. Shorts like that were taken in the film camera days, Rather than bluntly claiming something, maybe explain it a bit?
Is it the poor lighting? Is there something about that bird that requires the Sony CAF to capture it?
The autofocus system on the Sony is much faster and more accurate.
Yup, Swallows hunting 10 metres away requires an extremely precise and fast AF system.
At 10 metres with a 400mm , f5.6 lens , depth of field is 20cm.
Out of 400 images taken, about 360 were in perfect focus.
Additionally, I am lying on the ground which then means the extra challenge of the AF system dealing with grass and plants in the foreground.
This is in comparison to the EM1X / iii, which offer the best M43 for continuous af.
The new generations of sensor will make it possible. There have been rumors that the new GH6 will have a hybrid focus similar to Sony's. We shall see.I get it... It's the automation that's superb. However, guys like Tim Fitzharris were running around with Pentax medium format AF cameras taking photos like that and they are published. Doug Herr stuck to manual-focus Leica SLRs and a Sony A7mk2 until he eventually went with the L system. Neither of those systems have anywhere near as complicated an AF system as the Sony, but they're getting the shots.
If Tim and Doug can get it done with something other than a Sony A1, so can you. But I agree that, right now, Sony seems to have masterful handle on AF automation. Is that a software/firmware issue? A patent issue? I don't agree that it can't be done on m43.
As for the focus issue, this discussion was really about light and sensors. Of course film camera people did it. They used zone focusing and preset distances and depended a lot less on technology and a lot more on ability. But if we want to keep this thread on track (not that we need to) we should be discussing ASA12600 film...
No, my original post was pointing out the high iso differences and I further expanded by pointing out that different systems have different strengths. I was not extolling the virtues of Sony as much as I was about M43 but you focused on a part of my comment which was not controversial in any way or form and asked for me to expand on it. I am brand agnostic having owned most of them, and it was my fault for assuming that a response with real world applications and samples would not be taken out of context.No it's not about light and sensors... Unless I am misreading, he even explains his comment to me by extolling the virtues of Sony's latest AF algorithms. Photos like that have been done with cameras loaded with film well below ASA 12600 and Sony digital cameras aren't the only ones that can get a shot like that.
I meant the OP. It was about light and sensors. fsi22 mentioned focusing, which is what you commented on.No it's not about light and sensors...
