You have just turned back the clock by 50 years for me, I had a very good Geordie mate and I was invited up to see the Miners 'dance the banners in' what a spectacle that was, one never to be forgotten. Thanks.

Many thanks for prompt info Haris F.
Thats solved that nicely for me, I have an adapter so it fits my K mount bodies and functions very well.

Just having a clear out under supervision of SWMBO and came upon the above lens, had a good look on various search engines, but found no reviews for this one, what is shown on the topic title is all that is on the front of the lens. So I turn to the fonts of all knowledge.

Thanks for message. Still no idea of value. Think I will withdraw ideas of disposing of the lenses.

Poor old brain having a bad day today, have sent message, not sure if you will receive it, have found only 2 on Ebay, going for silly money (Japan and Australia) I will accept sensible offers

Good day all. Due to age and physical impairment I have decided to dispose of my lens collections (slowly). For example I have six F series lens, comprising:- 28mm, 50mm,100mm Macro, 135mm, 35-70mm and 1.7 F AF Adapter, all in vg condition, no idea of value etc. Any help or advice would be much welcome. I live close to Winchester, Hampshire. LCE local to me is an option but I would rather they all went as a package to a forum member who would appreciate them as I have done. Regards John.

Just to add my advice, I have this Pentax AF adapter 1.7 and for me it has been a lifeline, my eyesight is not what it was and it enables me to continue using my old manual lenses.

I can see where this is going, us men of a certain age need an assistant, male/female it matters not, who will transport you to proposed photographic site, set up your equipment, wheel you across then raise you up to see through the viewfinder, once happy with the set up you will use a remote to trigger the shutter. Assistant will dismantle equipment, wheel you back to your car and you will be returned to your home. Having downloaded and printed your? efforts you will show them to your wife, without looking at your efforts, she will then announce "very nice dear" and carry on with the ironing.

Thankyou. One less thing to worry about. Regards to all John

I should start this post with the fact I am now in my eightieth year and updating my Pentax cameras has become almost an impossible task for me. Is it imperative that I update? My k3ii, K70 and K1 (as far as I am aware) function perfectly with all my lenses both old and new. Advice please. Regards John.
