If you really want to shoot film, the MX is going to be the quiet option. JMHO.

I doubt anyone will notice the noise of your camera, well maybe the two or 3 people right next to you- but I assume (bad I know) you will not occupy a front and center position
for taking pictures. ;)

I don't know how this compares with what you expect, but I bought my 645z in Jan. 2021 for $2350; and paid $1800 for the 645D about a year before.

I would expect to pay somewhat less today.

Thanks for the post.
Looks like it is tough or at least time consuming to improve on #2.

"So is it really sensible to use plastic mounts for lenses?"

Yes, to produce a less expensive (and lighter) lens; you always have the choice to spend more if you wish- not everyone so desires.

Great points guys, interesting ways to look at "comparisons" for sure; I guess the only safe thing one can say is that the two cameras are different. ;)

That is what I said, the K1ii at the same sensor size has fewer pixels; perhaps I didn't make it clear enough- I agree with you.
The "crop" feature of the K1 is only equivalent in size and has only about 18megapixels vs 24 for the KP; hence that would be a fair comparison for evaluating the photos.

If using two different focal length lenses, or the same zoom lens at different focal length, to achieve the same image the effect of changing the number of pixels is lost;
it would seem then any comparison of results is like an apple to an orange.

It is like saying more pixels in the same size sensor results in more resolution, isn't it ? An equivalent comparison would be the same lens, same focal length, same image by using the "crop" feature of the K1ii.

And I left out "precise focus" as a compounding or confounding issue! ;)

While not strictly equate able, the K1 full frame's 36 megapixels covers about twice the area of the KP's 24 megapixels; so to be "equal" the K1 would need 48 megapixels!
But the size of the pixel/pixel density, diffraction, the lens used, and a host of other variables enter into the perceived finished photo.

The full frame K1 excels in image quality as does the KP, but not just due the raw megapixel numbers.
Given a choice, the full frame K1 should be used for wide shots, and the KP or other apsc for telephoto; unless you happen to have the "other" camera in hand! ;)

So essentially I agree with Mikesbike !
