Minolta 50mm f1.7 manual and Nikon f1.8 AF.
Although it’s cheating a bit as the Nikon is a screw drive autofocus rather than having it built in.
They still seem a lot bigger than the olden days…

The Minolta is from the late 60s. Thats a pancake lens, I have a manual focus Nikon as well somewhere and its not that small. Most brands back then did a specific compact lens.
To be fair there is a 50mm f1.8 for the Sony that looks about the normal size. Its just a bit rubbish, less resolution than most of the Zoom lenses.
One reason for larger modern lenses could be no one likes vignetting. By having the elements further away you produce a larger image spreading wider than the sensor.

I’d probably say the opposite, most modern lenses seem to have more vignetting and distortion as its easily corrected in software, in exchange for higher resolution.
Of course the solution for higher resolution is similar, use bigger glass.
$1000 sony vs $100 Nikon. Roughly the same sensor.
The Nikon has less distortion, vignetting and chromatic aberration. But no where near the resolution. (The Sony tops out at 54mp of resolution on the A7RIV but the Nikon tops out at 26mp on the D850.)
Fair enough, I just find 24mm frustrating, it never seems to be wide enough. I doubt I’ll get another (I have a 28mm already anyway)
Seems to be a change in philosophy - don’t worry about the stuff that’s easily correctable (geometrical distortion, vignetting, lateral CA, and worry about getting the thing sharp). Makes sense, really.
Yes, very much so. Other than the high price and massive size 
There is a stonkingly good Canon 40mm f2.8 STM pancake lens that shows that it can be done. A designed for mirrorless version of that would be great

Presumably it need an inch of adapter on the Sony, though?
Yes - I am not advocating using it on a sony as you say 26mm of spacer is needed defeating the objective . Just showing the best example of a pancake that I know.

Who did you use for printing ? Looks great.
Just the standard prints on Lustre.
I need to tweak a couple that came a bit dark but it’s so cheap it hardly matters.
I normally order 18x12” £1.30.
