Why Z lenses are so big?

Ricoh has become a "digital service company" (from its own words in their 2023 report) that goes far far beyond printers and copiers. I am not sure Pentax (that does not even show as such in the report) is going to employ that many new workers anyway. Pentax and Ricoh cameras are just a way for the company to remain "visible" in a specific market where Pentax used to be a major player (Spotmatic SLRs, and even Pentax 6x7), but it is definitely not what makes it run now.
Our discussion will not change how they are run. Pentax has had a series of U-tube ‘programs’ about their film project, beginning with one that assured viewers the digital wouldn’t be affected - but some western users aren’t convinced. We shall see what happens this coming year. My usage probably not be affected - I’m not aware of anything from them I would want to get. I expect your usage won’t be affected.
This discussion has no connection to Z-mount lenses.

I just took a look at a couple of 24-70 Nikkor lenses The 4.0 Z lens and the 2.8 AF-s have about the same size rear element, and both rear elements are just about flush with the back of the lens when at 24mm.
The Z lens is a lot smaller than the AF-s

The Nikon Z-mount has a relatively large diameter, which allows them to make lenses with a maximum aperture of f0.95. This was not possible with the F-mount. I have been a Micro 4/3 (Olympus/OM System) for a number of years now. One of the reasons I stick with Micro 4/3 and have not gone full frame is the size and weight of the lenses. This is an issue with all full frame mirrorless cameras. Even though the size of full frame mirrorless camera bodies has gotten smaller, lenses are still rather large and often do not balance well on the smaller bodies.

I love when people conjecture about things they have no actual knowledge of. I also shoot M4/3 and I love that OM-1. The camera is a beast, (capability, not size), and those smaller lighter lenses make it a no-brainer when I’m choosing what camera I’m taking overseas. It did everything I needed on my trip to Scotland last year and Italy this year. I also shoot Nikon full frame and nothing beats those 45+ mp raw files. And no, I have never had a balance issue with any of the lenses I use on my Z7 and Z9.

Guess I'l an oddBall in more ways than one. I use medium format lenses on my "D" Nikon cameras but the resolving power isn't the same as for lenses that were engineered to the "Full Format" 35 mm size, however when I use my prime "APS-C" lenses on the full format with great satisfaction. Haven't really done a study, no time, but I'm sure someone out there in UHH land would pick up the reins.
