It depends on the range really.
A 24-70mm is definitely 3-4 primes for me but something like the Canon 35-350mm is a different animal.
Leica used to do these two lenses
They are referred to as MATE (Medium Angle Tri-Elmar) and WATE (Wide Angle Tri-Elmar) and are “zoom” lenses with fixed focal length stops.
The MATE is stepped at 28-35-50mm and the WATE at 16-18-21mm which on their intended use (Rangefinders) were used with a specific ad on viewfinder that was so clunky it is known as the Frankenfinder.
They are not fast but are compact and have focal length stops that make sense so are very much a bag of primes (and very much more useful adapted on to an EVF body).
Some Panasonic fixed lens cameras (LX10 and LX100 spring to mind) emulate this by allowing you to use the zoom ring to increment to fixed focal lengths and it is a good feature especially on those with return to position on power on functionality.
I *think* some of the Sony RX100 do this as well.
I suggested in the other group that Panasonic should put LOFIC sensors in their ILCsand someone went on about mythical organic sensor, which quite frankly may remain just that.
Panasonic should just put LOFIC sensors in all their new cameras, and ditch Sony if it doesn't improve sensor tech enough.
I would love to see an Even Smaller GX camera with a 20-50MP 1inch LOFIC sensor. The LX10 is frankly too large for most pockets.
It lets them hit attractive spec points like 3x optical zoom and 12x zoom when using the digital shenanigans.
Although the 3x optical zoom is actually 3x switch as the intermediate points are digital and if you are in D-Log2 then it’s a hard switch as there is no digital zoom.
I think 45mm equivalent would’ve been better from a practical point of view but 2.25x optical zoom and 9x total zoom doesn’t look as good in the marketing.
Even though 20-190mm equivalent is still not too shabby !
A good practical look at the challenges around shooting with it in this video.
The GM1 is long gone, but here's the tiny a110 lens:
FWIW, my wife and I made a doc 10 years ago using the GX7 and the GM1 (with a different lens). It was fun. I did use the a110 primes I have for a short film.
Finally, I also have the a110 Pentax film camera and have started shooting with it just for kicks.
The LX10/LX15 is a solid little camera.
The big differentiator (aside from price) over the Sony 1” cameras is the f1.4 aperture at the wide end.
That comes with a couple of caveats in that it doesn’t stay f1.4 very far into the range and shooting in 4K there is a bit of a crop.
It takes my cinelike-D hack and I also put a magnetic filter thread on mine that enables you to put ND on it and/or in my case a Sony 2x TC that you can quickly pop on and off to extend the range.
These are some grabs from mine.
The top panel is lens at it’s widest, the middle is maximum zoom and bottom is maximum zoom with the TC on.
If you want to have one with a natural long zoom range on it then their other 1” from the time the TZ100 has a 10x optical zoom.
Can also take the cinelile-d hack.
