Why are these old telephoto lenses with the weird barrel focus/zoom mechanism

So

Amazing?

They aren't, or at least you're confusing the zoom mechanism with quality. The reality is, f/4 lenses are always going to be amazing. Slow lenses are always going to be the best in their class because fast lenses are always a compromise between refraction and correction. Slow lenses don't suffer from that duality, and are able to concentrate on a single variable (sharpness and optical quality).

It's like that old chinese proverb: "chase two rabbits, catch neither."

They are basically the precursor to modern 70-200 2.8s. some are shit and cheap, others are damn good at quickly zooming and focusing.

Push-pull zooms are fucking awesome, OP. I've got a Kiron 28-210 and a Tokina 100-300 f4 and in terms of speed and usability they're the bee's fucking knees. I shot airshows, wildlife, and sports events with the latter and had little trouble manually focusing since I could spin it into focus while zooming. 2-touch zooms can floss their filthy mouths with my ballhairs.

Well, sometimes they concentrate on some other variable, like compactness, price or build quality.

The Pentax actually needs to be at about f/6.7 for this to be a fair comparison iirc. Not that the 15mm is a sharp lens, because it's not.

Not that you really should compare lenses directly across different bodies/systems.

The Pentax 14mm 2.8 is really good. Not as good as the Fuji 14mm but it costs 1/3 as much.

I'd probably save myself the headache and get the 18mm f2 instead though. It seems like an overall nicer lens and I would barely notice the tighter fov but even if I didn't do that it just looks like the 14mm 2.8 fuji lens is better for not even that much more

There's just so many decent looking choices so it'd be easier to pick and choose depending on my needs instead of either one of these two lenses

I mean it's fun to use and useful for going from 100 to 400 instantly but shit like that is why they suck.

Do not underestimate the difference 4mm can make. I bought the Samyang 14mm after having used some shitty 18-125mm kit lens, and was blown away by how much wider the Samyang was.

the wider you get, the more noticeable a 1mm change in focal length is

Yeah, especially on crop, where 14 vs 18 is like 21 vs 27.

When I first picked up photography, these were my first lenses and I fucking despise them
Also all of them had some dumb fucking shaped aperture, either from poor manufacturing or damage
Always had a fucking egg shape to the aperture
