Go on, make me an offer - you know you want to
Both items, taking into account their vintage, are in good/very good condition and, as far as I can ascertain, fully functional. Pricing (excluding p&p; items will be shipped in accordance with the buyer's wishes and at cost):
Body and lens (my preferred option and hence offered at a discount) - £65.00
Body only - £50.00
Lens only - £25.00
With regard to the ME Super, my description of 'fully functional' is based on inspection and testing of the camera's metering, shutter and wind-on actions. Should the buyer find the camera to be defective in actual use (i.e., when used with film), they will, on provision of the supportive evidence, have the option to negotiate a partial refund or, if preferred, receive a full refund excluding the original cost of p&p.
Please note that the lens cap, whilst remaining secure when attached, is missing one of the spring-loaded retaining clips, as is apparent from the uploaded images.
Note that offers for the camera and lens will take precedent over those for the individual items, irrespective of the order in which they are received.
I have checked prices (dealerships and 'fleabay') on line and pitched mine accordingly (comparatively low, in fact), but remain willing to negotiate within reason.
Thanks for looking
Jon

Very odd. So when you have adjusted the dioptre correctly for a focussed image, the gridlines/VF info display are not sharp ?
The dioptre adjusment needed to bring the subject, rather than the guide overlay, in to sharp focus when using MF is minimal (1 step difference for my 'shooting' eye), but the impact on the proportion of 'keepers' (viewed at 100%) has been dramatic, incontrovertible and consistent, without further adjustment, for every lens I have tried thus far whether of Pentax or third-party manufacture.
Were it not for this discovery and it's sharing on this forum by Chris and Paul I suspect I would have returned the camera to SRS (bless 'em) for a refund

Comment by prsjnb posted on K-3iii: manual focussing using OVF at 05/03/2022 - 11:28


With the lens detached from the body, are you able to rotate the focussing ring?
If you hold the lens with bayonet closet to your body and the barrel markings facing up, you will see that there is a clamp mechanism on the RH side. Check that this is disengaged/off.
If you switch to manual focus on the camera body, are you able to focus with the lens?
Check and clean the contacts on the lens bayonet and camera mount, preferably with a lint-free cloth moistened (barely) with 70% (v/v) isopropyl alcohol (propan-2-ol) or, failing that, an alcohol wipe or Steri-Swab of the kind used to wipe the skin immediately prior to being given an injection. Allow to air-dry fully before re-mounting the lens and testing.
If possible, test the lenses screw-drive AF on another body.
Have you/are you currently experiencing AF problems with your K-3iii and any other lenses in your possession?
These checks should allow you to determine if the problem lies with the lens or the camera body. You would have to be very unlucky for it to be a problem with both.
