50mm lenses

Failing all that, clean the metal mount on the lens (and perhaps the electrical contacts on the camera mount too). It needs to be conductive for catch-in focus to work.
It doesn't work on my M and K lenses on which I've stuck a piece of selotape where the electrical contacts would be on an A lens. I've done this to enable Av mode with all apertures, but that's another story!

I'm still not decided if go for AF or MF.
To sum up:
- AF 1.4 is the best one, only more expensive (actually I can spend £155), even if dpreview tells about a limit:
"However this excellent showing when stopped down does come at the cost of an unconvincing performance at large apertures; the lens is very soft indeed at F1.4, and while we described the Canon 50mm F1.4 as 'dreamy', the Pentax renders scenes more as though you're looking through a fine veil of mist. This is accompanied by a distinctly problematic rendition of out-of-focus backgrounds, to which it imparts a jarringly hard-edged appearance and substantial levels of green/magenta chromatic aberration. This in turn slightly limits the lens's usefulness for shallow depth of field portrait use, an application for which the (much more expensive) Sigma 50mm F1.4 EX DG HSM is rather better suited. Indeed it will be interesting to see how Pentax have chosen to design the recently-announced DA* 55mm F1.4 SDM, which is described as being particularly suitable for portraiture."
then MF, in order of quality (that seems given by the aperture value?):
-f 1.2
-f 1.4
-f 1.7
-f 2.0
Where f1.2 is the best one but more expensive, while 1.4 and 1.7 are good enough.
As I said, I can spend £155 but on the other hand I would like the idea to own an old, manual focus.
Is there any other usual (commomly bought) focal lenght that is cheap and good quality in the MF version?
Guys, any further comment on the topic?

Max, I think the FA 50mm f1.4 would be a good choice for you if you don't plan to buy an auto focus f2.8 zoom that covers 50mm any time soon.
For MF lenses of other lengths, there is a Pentax-M 100mm f2.8 for auction on eBay at the moment. Anything more modern that provides the same image quality and speed costs megabucks.

Pete, well, seem to have tried everything to no avail.
Will come back to it another day, when I get my M50, it might just be a prob with lens, I have noticed though that it does make a bleep noise when I move the camera on the tripod. hmm
Many thanks
Chris

If you really want to try the manual focus go for the A 1.7 or 1.4
Image quality will be great on both. If you cant get one at the right price go for the f2
The f1.2 will cost an arm and a leg, and the image quality will not be better than the 1.4 or 1.7, and may even be softer until f8.

do you mean the 50mm f2.8 macro?

No, I mean something like the Tamron 17-50mm f2.8. You won't bother using a 50mm prime so often once you've got a high quality fast zoom (even though they're not as fast).
My suggestion is to get an FA 50mm f1.4 if you do not plan to get a fast zoom, or an A 50mm f1.7 if you do.
I'm not trying to encourage you to get a new zoom, I'm just mentioning it just in case you're already considering one.

A big thanks to the help I had with settings on my K200D.
I have finally "got it"
Now using 'A' manual lens successfully.
The green button sets the shutter speed on this camera.
And as was suggested, must be used in catch in focus mode.
Being newbie, took a while to get my head round it.

As I said in my first post, the FA50mm 1:1.4 is a superb lens. You'll definitely not be disappointed with it's sharpness, low light performance, or bokeh. And it's an AF lens.
Go for it, even if you do plan to by a quality zoom that includes 50mm in its range.

Cant manage to press shutter and turn focus ring, I put cam in AF mode with manual lens fitted, set mode dial to manual, sort out exposure and press shutter button and it activates.
Does the green hexagon light up in the viewfinder when the subject is in focus?
"Using aperture ring" needs to be permitted as well.
