Difference between m and a
If you're just starting to use manual lenses, remember to enter the menu and set the camera to allow the use of lenses without an A mode. If you don't do this then old manual lenses will not work.
Good luck with whichever you choose.

The A series will work with almost everything, apart from not being autofocus of course. Just set the aperture ring to "A" and let the camera control things.
It's really two extra steps in practice ... You get quick with practice, but the A type lenses eliminate these steps, which can be more convenient.

The 'M' lens just shows M Lens and the speed. No aperture.

The K will work in the same way as the M. It's a very good lens and I'd say this is a very good price for it.

All of them are in excellent condition and if you want one
I could sort out a good one for £39 posted. Both caps included
but they won't be Pentax originals.
Let me know by PM if interested.

I've got about 4 Pentax-A 50mm f/1.7's mostly on bodies.

The way I've worded that could be confusing The £39 is just for a lens not lens
and body. I ran out of body caps so I put lenses on until I get some. One of the bodies
is an MZ-S

You're really restricted to M mode only with the original smc lenses. Even in Av mode, as there's no contact electronic contact the camera does not' know' what aperture is set on the lens and cannot control the lens aperture. As said above, you set the aperture on the lens first, point at where you want to meter primarily then press the green button ... The lens stops down and the meter reads the light and sets an appropriate shutter speed. You can then change the speed in order to make it darker or brighter.
Just pointing out that these limitations only apply to bodies with crippled mounts (all of the DSLRs and some of the MZ series film cameras). I usually use HyperManual so I don't really notice the extra step. Otherwise 'K' & 'M' lenses work fine in M and Av on film bodies. A future FF with non-crippled mount would be very interesting!
When using my K-5, the only real drawback when using M lenses is that because you need to use Manual mode, you lose the horizontal spirit level in the finder (it becomes the exposure +/- indicator).
