That's why I sold all if my AF Nikon F lenses and bought just two Panasonic lenses, the 40/2 and 14/2.8. The 14 will be replaced with a Leica 15/1.7 if I ever get serious about photography again. Until then I'm using an old Ricoh GRD 3, which is still amazing - no distorsion, great photo quality, great lens, stellar ergonomics.
