Rumors of GFX100 replacement in 2023

That's a good idea. It would help, but we still need finer sampling.

A weak AA filter would be helpful

I'd like a zero at around 0.6 of the sampling frequency.

Would that eliminate most…or all aliasing…within reason I mean

No, because of the color filter array. It would eliminate almost all aliasing if the sensor were monochromatic.

I'm hoping for a 102MP stacked sensor along with a much faster CPU. I'm not a big body GFX100 buyer, but when it makes its way down to the smaller body GFX100S, this would get me to upgrade. I wonder if they'll follow the X-H2 path and produce two GFX models for professionals, one focused on resolution and the other on speed:

1. GFX160 for ultimate professional image capture (similar to X-H2)
2. GFX100 II for ultimate speed (similar to X-H2S)

Either way, I want a GFX100S with faster sensor readout and much faster CPU. That will be super compelling and prevent me from moving to the high resolution full frame cameras that keep calling my name...

Correct me if incorrect, but I think the stack sensor allows for 150mb without significantly changing sensor size so the lenses will cover the sensor.

I thought the purpose of the stacked sensor is to allow the on chip presence of additional electronics that speed up through put - thus allowing faster frames per second, faster AF and so on. Basically it speeds things up at a small cost in noise and dynamic range. It doesn't do anything for squeezing more pixels on the chip. Perhaps you are thinking of the Foveon layered sensor which is a completely different kind of stacking?

Has any larger than 35mm sensor ever been manufactured with an AA filter? I can't think of one off hand.

In terms of finer sampling, aside from delivering more detail, the ideal I think is a sensor that out resolves the lens. Then aliasing can't occur (I think). Given that there are so many great lenses being designed these days, what is the minimum pixel count that would out resolve any practical super lens that had any chance of making it to market. Presumably there is some kind of physical limit on how good a lens can be. I'll take a guess - diffraction limited corner to corner at maximum aperture?

I think we are talking about cutting the X-H2S and X-H2 camera sensors at 44x33 size. That would allow for fast read out stacked 100 Mpixels sensor (from X-H2S) and a 156 Mpixels sensor (from X-H2).
Having these two options for a camera would be interesting.

At best aperture with GF lenses, Between 800 and 2000 MP, for a sensor with a Bayer CFA.

Stacking two pieces of silicon does not make the pixel pitch finer.

What would I like to see? Not to much really. I'm pretty satisfied with the 100s for what I shoot with it. But...
1. An AF system similar to what is in the XH2/XH2s/XT5 would be nice.
2. A couple of more frames per second wouldn't hurt either.
3. Higher res EVF.
4. A couple of more programmable buttons on the front.

I'm OK with the 100P sensor. I'm not seeing evidence of aliasing in my prints, although I'm sure there are situations where it could show up.

Maybe you’re thinking of Back Side Illumination which moves some “wires” more out of the way?

The GFX 100x sensor is already back side illuminated.

I think you're asking for a lot from the next model :-) :-) :-)

You got that out there before I had time to recheck the specs, lol. Didn’t want to accidentally say what isn’t so. But do I have it right that BSI can help with “funneling”?
