And I went out again earlier - thankfully an old friend was able to get me motivated!
I'm very pleased at the result!
I also spotted an extremely bright meteor that seemed to last ages in the sky, lots of other people saw that one judging by the Twitter reactions.

Comment by johnha posted on FS: Cheap (but not too nasty) lenses at 10/07/2020 - 18:18
I have a number of old lenses for sale, they mostly work OK but have some issues. Unless otherwise stated, they are free of fungus, have snappy apertures and generally work as expected. Prices include UK postage:
1) FA 28-80/3.5-4.7 PowerZoom: One of the original PZ lens sold with the Z-1. The PZ switch at the front of the lens is broken (they're fragile). The Power/Manual zoom mechanism works and the lens will PZ on my K-5 & K-1 - it's just the advanced zoom modes available on the Z-1 that won't work). Some dust and some minor marks on the front element that won't really affect IQ - £20.
2) FA 28-105/4-5.6 PowerZoom: One of the original PZ lens sold with the Z-1. The PZ switch at the front of the lens is broken (they're fragile). The Power/Manual zoom mechanism works and the lens will PZ on my K-5 & K-1 - it's just the advanced zoom modes available on the Z-1 that won't work) - £40.
3) Pentax F 70-210 f/4-5.6 (non-SMC, AF problem): When auto-focussing on my K-5 or K-1, the focus rings sticks half-way through it's travel and the camera thinks it's hit the end-stop and refuses to drive it further. Manually focusing is OK - £20.
4) Super-Tak 28/3.5: (49mm filter thread version) with significant fungus/haze: £20
5) Super-Tak 55/2: which won't stop down: £20
6) Tamron Adaptall (not ADII) 28/2.8: No mount: This the original Adaptall series of lenses (not the later Adaptall-II) but the ADII mounts fit and work, good condition: £20
I also have a Pentax SFX(n) ever ready case (tatty): I didn't even know they made these until an SFX arrived in it: £10
Thanks for looking.
John.

I did a quick test @17mm compared with my K17/4 FE on my K-1 - the two are very similar, even into the corners (where FE's lose detail anyway).

Generally, film era lenses work very well (assuming they were good on film) - you may have to stop them down a stop more than a modern lens and having AF and an 'A' aperture setting helps. The very best (D-FA*) lenses will be noticeably better, but users of many 'normal' digital lenses still report CA and purple fringing - which may improve over film era lenses but perhaps not enough for me to consider them.
My favourite lens on the K-1 is the FA43, my most used is the FA20-35/4, my mid-tele is an M150/3.5 and my longish zoom is an M80-200/4.5 (the Tamron SP70-210/3.5 is much bigger & heavier but probably better).
