My experiences/comments about the process here:
Thanks, that's very useful. I linked to one of your posts from my article on autofocus adjustment hints.
Do focusing screens come with a set of shims or where did you source yours from?

focusingscreen.com shipped split-image screens to me with thin plastic shims (~0.10mm).

The Pentax bodies ship with a stock shim installed. It's the copper-coloured shim, if one has ever replaced their stock-screen.

In my K-m, the stock shim was 0.40mm. Another user found that the shim in their K20d was 0.20mm. See this post: https://www.pentaxforums.com/forums/551948-post18.html

(It may be that each body is individually shimmed in the factory?)

Replacement shims are available from Pentax in 0.05mm deltas. {i.e. ..., 0.25, 0.30, 0.35, 0.40...}mm.

Other users of this forum have made their own shims from suitably thin materials such as paper, transparancy paper, film stock, metal shim stock, pop-cans, etc. One would need a micrometer or precision-caliper to accurately measure shim material. Users with paper shims have reported moisture absorption that affects their focusing, so those are best avoided.

Shims can be stacked. For example, a 0.20mm and 0.10mm shim together creates a stack of 0.30mm. If one makes their own shims, it may not be convenient to find a set of sheet materials that vary in 0.05mm increments, so it may be necessary to stack thinner materials.

I find that I love my Nokton more and more every day. It's great for still life and portraits, especially the latter

Thank you for sharing your pictures. I love particularly your 2nd shot.

I agree strongly that the Nokton is a superb lens. The IQ is great and I like the robustness (basically WR).

Ditto on this

Ever since I got my Voigt, it has become my main lens, pushing aside a set of other excellent lenses (DA40/2.8 and Tamron 28-75/2.8). But the results have been much more keepers and more PPG photos

The lens is superb for studio work:




Or landscape:






And especially abstracts:

The other thing I like about the Nokton is that it is manual focus. So smooth.
