Test pic with the cheap Pentax-F 50mm f1.7
K-3 II, K-3 and a K-70 from SRS



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

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.

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

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