Comparing weights with Pentax cameras

I found this a little disconcerting [Ref 1]:

Pentax K-1ii is 240 grams heavier than a Canon R camera + lightest adapter
Pentax K-1ii is 200 grams heavier than a Nikon Z camera + adapter

Pentax K-3ii is 30 grams heavier than a Canon R camera + lightest adapter
Pentax K-3ii is 10 grams lighter than a Nikon Z camera + adapter

And this is sobering for those of us who relish Pentax's IBIS advantage:

From: NikonUSA

"Approximately 360 F-Mount NIKKOR lenses can be used"

"Every compatible lens benefits from a Z series camera’s built-in VR. Fast primes. Wide-angle zooms. Space-bending fisheyes. And F-Mount NIKKOR lenses that already have VR get the added benefit of roll axis for a total of 3-axis VR"

Reference [1]

Nikon Z7 body - 675 grams
Nikon Z6 body - 675 grams
Nikon FTZ Adapter - 135 grams

Canon EOS R body - 660 grams
Canon Adapters - 110 grams, 121 grams, 130 grams

Pentax K-1ii body - 1010 grams
Pentax K-3ii body - 800 grams
