So, for those interested, here is the update...
I found some RPX 400 in the fridge, which, in my opinion, is not a nice film when Rodinal is the only developer around.
So, the only use it has for me is test film...
I screwed the front taking lens group outward until the black ring was aligned with the silver ring sitting around it. This is about 0,55mm outward from it's most tightened position.
I took some shots with bracketed focus to compensate for the change in focus.
I then shot an image of the same composition but with the front group screwed all the way in.
Surprisingly, the images taken with the front group screwed outward, showed the best results. The far edges still focused inward compared to the centre, but not nearly as much as with the front group screwed in.
Bellow are the links to the images. Please note, the tree is not the focus point. I focused for the hills, at infinity. Shot at f/3.5
Front group screwed out and Front group screwed in
