The other night, I used ISO 6400 with the Fujifilm GFX 50s II camera, and of course handheld and the help of the built-in image stabilization. The large photo above, however, I have cleaned up a bit with Adobe Noise AI. It is impressive to get so many fine details at ISO 6400 with a medium format camera, handheld !

This wouldn't be possible at all with the analog Hasselblad XPan - unless of course you used a tripod and several seconds exposure time...

Now even the stars are almost dot like sharp - which I think is impressive given that I didn't use any tripod. The Fujifilm GF 50s II grows on me for every week i use it more and more (than ever before). It is a pity, that the only way to get to the newer tech (from GFX 100 series), is a 102 MP sensor camera.

I would love an updated 51 MP sensor
(instead of the newer 102 MP sensor)

I would LOVE a sensor that does the same, but instead as a 51 MP sensor. (That will not happen). There is no 33x44 mm medium format sensor other than the one Sony developed / introduced in 2014, which was used in first generation Hasselblad X1D, and Fujifilm GFX 50 series (as well in the Pentax 645Z camera).

I am not a big friend of the newer 102 MP sensor really - because i am somewhat skeptical about the noise behavior. Yet, I can't fully judge that, because I don't have a GFX 100 series camera (Instead I downloaded sample RAW files in order to see more about the quality in those images files. Some of them were actually impressive). But 102 Megapixel... really ? How much is one image - like 200 MB ?

I don't aim at such a camera - because it is really an overkill for what I do in my photography. The jump from 20 MP in most of my cameras, to 51 MP in the Fujifilm GFX 50s II is already significant.
