S16 K-3 lens mount adapter question

[Skyler Carrico]

Hi all,

I have a S16-adapted K-3 with the standard M42 mount and am wondering whether I can use this adapter to be able to mount PL lenses:

Would this mess with the flange distance?

Thanks!

M42 to PL is a very common adapter, as long as the one you buy is good quality and accurately machined your flange depth should be OK.  I don’t have experience with Ironglass adapters, but their products seem well made.
 
Adapters just space a lens out to the adapted mount standard, so in this case the 45.46mm flange depth of M42 needs to be spaced out to the 52.00mm depth required for PL lenses. The best way to check it is to mount a zoom you know is good, focus at the long end and check that the focus stays sharp as you zoom out to wide.
