I just entered the world of mflens as I bought a sony s6000 few days ago.
I think I'm doing something wrong because in some cases I'm having very bad results, in particular regarding CA.
Following a couple of examples (the pictures are not nice, but are those with very visible problems):
Shot with Tamron Adaptall-2 70-210 - ISO 1000 - 1/2000 - I think wide open at 210 mmm
Crop:
Shot with Tamron Adaptall-2 70-210 - ISO 640 - 1/1250 - I think wide open at 210 mmm
Crop:
Shot with Olympus Zuiko 24mm f/2.8 - ISO 3200 - 1/50 - I think wide open
Who is responsible? The lenses, the camera or (most probably) me? |

Welcome on the forum.
The CA are more pronounced with certain lenses if you shoot high contrast scene and around edges.
Usually they are not that bad and are really easy to fix in Lightroom. _________________ Stefan

Also, if I'm correct, chromatic aberrations are most pronounced at the maximum aperture of a lens and stopping down reduces it. _________________ DSLR: Canon 6D, Canon 400D
