Nailed!
K-3 II, K-3 and a K-70 from SRS (having now relegated the K-30 /"K-50" to a backup body), & some Sigma and Pentax lenses (and a lot of old 35mm gear!)

Woof!

The lens may be cheap but it's certainly not nasty.

I've heard that the F version has much noisier AF than the FA version. Any comments on the sound it makes?

Generally speaking that is true - but there is significant variance between copies. Some have quite a "Whirr" to them while others are much quieter. The AF of several of the F series lenses also appears more aggressive than FA's and later - the F*300 is very quick to focus, it feels like it's about to launch sometimes

The F lenses were born when the motors in the then AF bodies (SFX & SF7) were much less powerful than today. As such the lenses had to have as efficient an AF drive train as possible - they are much less damped for manual focussing than the later FA lenses (making them in my opinion much faster with screw-drive AF than the FA and later lenses). It wouldn't surprise me if they made more noise when attached to a more powerful AF screwdrive. The Z-1 had a more powerful motor than the SFX/SF7 - sometimes they hit the end-stop with quite a wallop.

I bought my 'shop demo' F50/1.7 back in the day for 20 from Dixons - I'd bought the last SFXn from them but the lens was 80, I went back and offered them 50 (they didn't have any other Pentax gear in). They refused, but the next week it was down to 20 so I snapped it up. The week later I went back and bought their last AF240FT flash for another 20. In some ways it's a better lens than my FA50/1.4 - which is apparently prone to flare due to the front element being closer to the front of the lens barrel.

Thanks all!
Yup, after being cleaned up it's a great little performer

No idea how much more noisier this is to a FA sorry!

Yep! Got lucky with it

Even found my square clip on lens hood that makes it look pretty sexy on the K1
