The Pentax 21/3.2 AL Limited is for APC. Don't think the image circle is sufficient.Hello Michiel!
Yes that is looking outstanding!! (even using the pixel-shift I guess), you can almost read the smal letters on the parking sign down in the right corner! When using C1 9.1.2, it seems like you just use the distortion-slider in the lens correction (I hope that would be sufficient)
That I will consider.
Pinhole also uses a M20/4 that seems rather sharp too, which is unavailable now, and used, didn't seemed easy to get.
Then there might be some of the other sharp lenses but I don't know how they would behave on fullframe. There are the
Pen 21/3.2 AL limited, which is sharp stopped down to 5.6 or best at 8 ephotozine claim.
Pen 35/2.8 DFA should be sharp too.
and then I would jump up to the Pen 100/2.8
Will they AF? (apart for the Samyang)
And the new Pen 28-105/3.5-5.6 could be a cheap solution for all-go non-critical work on houses (while it seems acceptable sharp for the most commen situations)

I would like to know more about the 28-105, but no serious tests yet.
All FA lenses will AF but DA lenses are for APC
Some DA lenses work fine ON FF like the DA 50/1.8
BTW I bought myself a Voigtlander SL 40mm in PK mount. It seems to be a wonderful sharp lens.
I tryed the Pentax shift 28/3.5 on my A7r. Image quality looks wortless to me.
The Pentax-A 28/2 is a wonderfull lens already on the A7r
These are all non AF lenses.
