I think there may be some misunderstanding about which lens I'm working with here....

You are using Nikkor 55mm F1.2 on Pentax K-S1 with adaptist right?

I have 3 Pre-Ai Nikkor: 55mm F1.2, 35mm F1.4 and 85mm F1.8 and 2 more Ais Nikkor: 24mm F2.8, 35-70mm F3.5.
I only used the Pre-Ai on my K1 because I worry the Ais' rear mount is too protruding and it might touch K1's mirror, anyway though it fits my K1 but it is not locked properly hence i am curious about adaptist.

So, did I understand your work correctly here?

my apologies - you seem to have a complete grasp of the project...

one note, however, neither of the two Nikkor lenses lock onto the camera body - one positive twist will take the lens completely off the body...

No need to apologies, by the way, even with adaptist it is still not locked like native K mount lens?

thank you


no - there is no locking of any lenses (other than K-mount) on the mount - every lens is held on the bayonet by friction....

I have yet to try an OM-mount (coming this week) or AR-mount, so we'll see...

quick update - I have two Contax-mount lenses here and neither will focus at infinity; they both get almost all the way there..... but just short

both lenses are amazing at all points up to that end, and neither lens cost me anything even remotely close to serious money...

I am a bit disappointed in this, but I have a Nikkor that should be arriving tomorrow and am considering the Olympus option soon....
Did you try to fix the infinity focus by changing the AF fine tune*? This is a long shot, but might actually work, and would not take a lot of your time.

* i have no experience whatsoever with AF fine tune and MF lenses

I see where you're going, but I don't think that it will help if the lens physically cannot reach because of a limitation due to the registration distance/mount/bayonet tolerances.....
