Let's say we have enough pixels...


I have seen this video recently: https://youtu.be/Fd77tapDdPE

In short, Matt Granger suggest that Nikon D700 (and similar) represents best value.

In a way, it means that 12 MP is good enough. It could be said that the new Sony A7sIII goes in the same wane, but it is intended for video.

On the other hand, we can buy good lenses and probably wanting to make best use of them.

Just to say, my experience is that 12 MP is pretty much OK for 16"x23" prints, that I normally make and if we just show images on screen 12 MP is perfectly good enough for 4K.

Now, a 24x36 mm system with a good lens can deliver a huge amount of information. To avoid aliasing we need an OLP filter reducing detail in the sensor plane.

So, I would guess that we would need a smaller sensor, if 12 MP was just what we wanted.

It could be that Fujifilm has a smart strategy with their X-system. Building a system around APS-C and optimizing the lenses for it. To some extent, they can built faster lenses for that smaller sensor.

But, I would think for SNR (Signal Noise Ratio) a larger sensor would be preferable, or rather a larger aperture diameter, perhaps.

In the end, I think that high MP counts make a lot of sense, unless we need small image size. If we need small image sizes, using smaller sensors may make sense.

Best regards
