That was the clue I was missing, thank you! (For a while I tried to play around by myself with the thin lens equation and was banging my head to the wall as I didn't have any value for s' and for some reason I didn't notice this similarity of triangles. Which should be QUITE obvious when...

Yes, there should be two different lenses.

It means that there are two different focal lenghts to be figured for the same setup.

Only the image at P´ is diminished, original object at P is 80 mm tall.

Hello, I've come across an problem that requires the lens to be at least about 350 mm away from the object. Object to be examined is 80 mm tall and imaging plane is either 11 mm or 25 mm tall. I've tried to calculate required focal length, but have not succeeded. Distance from lens to imaging...
