I recently tried to get this working on my EOS Rebel T4i (650D) and ran into some strange problems that caused core dumps relating to malloc. So, it's important to override with correct lens name (maker + model), find a way to handle '' ( Lens ID database) plus additional infos about focal length and aperture to make software heuristic happy?Ĭan someone try to replicate this experiment with your lenses (both Canon and Third Party if possible) and editing software? Preview(MacOS) -> Tamron AF 17-50mm f/2.8 Di-II LD Aspherical -> looks better now. RawTherapee -> Canon 17-50mm -> looks like is using '' with 'Canon' as prefix (still Bad.) Looks like is comparing '' with an internal lenses database (prompt for downloading correct module)ĭarktable -> Tamron AF 17-50mm f/2.8 Di-II LD Aspherical -> is using '' straight off exiv2 Lens : 17.0 - 50.0 mm (35 mm equivalent: 26.9 - 79.2 mm)Īdobe Photoshop -> 17-50mm -> is using '' (NO Automatic lens corretion!)ĭxO Optic Pro 10 -> Tamron SP AF17-50mm f/2.8 XR DI ii LD Aspherical (IF) Lens ID : Tamron AF 17-50mm f/2.8 Di-II LD Aspherical Let's try compare with a picture taken with an automatic lens: (Tamron SP AF 17-50mm F/2.8 XR Di II LD Aspherical )Ĭode: Lens Type : Canon EF 28-70mm f/2.8L USM or Sigma or Tamron Lens RawTherapee / Preview(MacOS) -> Canon Telemegor 180mm f/5.5 -> what is causing the prefix?

Lens is showed differently on each software:ĭarktable -> n/a -> is the same for you zLost?
