How to change focal length in EXIF
This 280mm reading in EXIF has been going on with this lens since it's introduction. It is simply something I see no reason to be concerned about as it makes no practical difference anyway.-- hide signature --
It does make a difference to me, since DxO does not apply any lens corrections when it reads an erratic focal length. And the Tamron 18-270 has quite some distortion to correct.
So what I need is either a tool that can update the focal length in Exif (batch wise preferrably) or any tips how to force DxO to use a specific profile.
