No, the sensor it's amazing, the lens it's not , it's good but not great, as expected for an almost pancake lens. Waiting fir serious reviews with real measurements, but i would be surprised if can resolve more than 50MP.
How do you convert MTF to MP?
I Just downloaded few raws from web, and globally they are worst from what I get from a 40MP sensor and a sharp lens, and with too much chromatic aberration for my taste.
You have made a quantitative assertion. Assuming you do have an MTF curve in cycles/picture height, how would you calculate the number of MP, and what is the basis for that? I personally find discussing lens sharpness in terms of MP to be fruitless and something that usually comes down to handwaving, but if you have some rigorous method, I'm all ears.
Obviously i can't comment MTF that are not available for the moment AFAIK, but as a fixed lens camera i comment rhe final results i can see on the web.
Anyway we will see from trusted review and measurements when will be available.
i said the sensor is great the lens it's not from what i see. and thanks god i still have eyes and after more than 20 years in the business they are well trained.
when i say that i doubt the lens can resolve more than 50MP, considered we are talking about a fixed lens camera, where all you can judge it's the final image i mean that i am sure that a 50MP sensor with a sharp lens can get better result than this system.
Are you saying that a 100 MP sensor with this lens won't give sharper results than a 50 MP sensor with this lens? On what do you base that assertion?
It would have to be a pretty bad lens to not alias with a 3.76 um sensor on a Bayer CFA camera. I've seen no indication that the lens is that bad.

here you can see a FF 60MP sensor with a sharp lens (and same sensor pitch)
Sure RF here is cropped to 35mm Equivalent, basically cropping from the 11648 px to 9504 px , but that 20% more pixel will never get back that difference, that lens is quite soft in the corners at least at F4, and show more CA than i can accept from any system at that price.
anyway i will be curious to see the same comparison with let's say a sony a7CR and a really sharp 28mm lens
anyway i hope to have an RF to test soon
I am going to write my non-scientific amateur findings shortly. I can’t comment on CA which I dont find bad with this lens, but it has been designed with similar principles to the X100 lens. The first version not being sharp at f2 close up or infinity. The 2nd generation lens has improved on that but still makes compromises. I have compared the GFX100RF lens to other RF lenses, eg the 50mm f3.5 which is very sharp, if not the sharpest of the RF lenses.
you are right, close up at f4 the GFX100RF is sharp but not as sharp as the 50mm. However closeup for the 100RF is almost 10cm, whereas for the 50mm it is 20-30cm. As the 100RF lens goes further out, or switches to f5.6, it becomes very very sharp. This means at normal distances or at mid apertures the lens is super sharp. This makes sense. If I go that close for a portrait or macro, compared to DSLR lenses it is still sharp, but I suppose the slight performance drop won’t effect the use case of travel or street with this camera, or landscape at f11.
the edges at f4 are also not as good as the 50mm, but the mid and centre are. That’s a bit “so what” for the use case.
like I say, this is just me comparing pixel level, it is not a technical or professional summary which you all are much more knowledgable then an amateur like me.
however it does square the circle between the independent reviews, which largely gush about the lens, and the hardened GFX shooters who express disappointment. It’s because their technical comparison of the extremes of this lens to their interchangeable lenses are showing the compromises on the 100RF lens. Whereas the reviewers who are using the use case of the lens, travel, street and stabilised landscapes, are having a whale of a time.
