Lens calibration: Olympus M.Zuiko Digital ED 12mm f/2.0

Post by Niku »

Here's a quick'n'dirty, manually generated but to my eye reasonably accurate, lens calibration for the Olympus M.Zuiko Digital ED 12mm f/2.0 Micro 4/3 lens:

begin lens
group: micro43
multiplier: 2.0
aperture: 2.0
menu_lens: M.Zuiko Digital ED 12mm f/2.0

cal_abc: 12.0 0.000000 -0.025000 -0.025000
end

Add the above into profile_micro43.txt. In order to have the lens automatically recognized by ASP when using an Olympus body, add the following line into profile_olympuslenstable.txt:

0 7 16|M.Zuiko Digital ED 12mm f/2.0

If anybody has the means and time to review and improve the above profile, feedback would be much appreciated.

i search for three magics numbers, here: http://syscall.eu/#pana or here : https://build.opensuse.org/package/view ... 0ef484b46e but it is not very accurate.

This is my lens calibration, manually generated with my eye, with a Panasonic GH2 body. I have had the following lines into /opt/AfterShotPro/supportfiles/Profiles/LensProfiles/profile_micro43.txt
begin lens
group: micro43
multiplier: 2.0
aperture: 2.0
menu_lens: Zuiko Digital ED 12mm f/2.0

cal_abc: 12.0 -0.001000 -0.016000 -0.014000
end

In profile_panasoniclenstable.txt i have add this line
OLYMPUS M.12mm F2.0|Zuiko Digital ED 12mm f/2.0

The OLYMPUS M.12mm F2.0 came from exiftool.

This is my feedback
