Who only 16k for a camera sensor

I have the G7 camera which has a 16k pixel sensor and I noticed the Panasonic produced other cameras that have a 16k pixel sensor, so I'm wondering why not move to higher pixel sensors like other manufactures have.
The only advantage of a 16k sensor was when I was only holiday I could take a lot of photos without fulling up the media card.

Hi!

How big are you printing? 30x40cm photos are great from both sensors. And if you are printing way larger, 4mp might not do that big difference, as one might expect.

Other thing is of course newer technology: newer sensor may produce little less noise at higher iso's.

Someone already suugested buying more cards. I think that is a good advice.

I've got very nice A2 (594x420mm) prints from 16MP but when I had an exhibition last summer the feedback was: fewer and bigger! So what do I do now? As my images are mainly of rocks and walls I could get a hi res model or learn hand held super resolution or do panoramas. Or go 40MP FF. Or accept the lack of sharpness from up close.

A discussion at https://www.markuswaeger.com/2019/02/12/aufloesung-und-druckformat/ argues (in German) for the latter, essentially stating that the larger the print the farther away from it you will actually stand to watch it, hence the lower dpi are required so that the required number of MP is lower than you could think.

From two key tables in there;

If you retain 300 dpi whatever the print size:

18MP => 297mm × 420mm

24MP => 340mm × 500mm

36MP => 400mm × 600mm

50MP => 500mm × 750mm

If however you factor in some reasonable viewing distance depending on the size of the print:

A2 print at 1m: use 90ppi≈ 2,2MP

A1 print at 2m: use 60ppi≈ 2,8MP

A0 print at 3m: use 45ppi≈ 3,2MP

Poster 252cm × 356cm at 5m: use 30ppi≈ 12,5MP

Perhaps worth a try, see if that works for you?
