Lens calibration: Olympus M.Zuiko Digital 12-50mm f/3.5-6.3

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 12-50mm f/3.5-6.3 Micro 4/3 lens:

begin lens
group: micro43
multiplier: 2.0
aperture: 3.5
menu_lens: M.Zuiko Digital 12-50mm f/3.5-6.3

cal_abc: 12.0 0.000000 -0.025000 -0.015000
cal_abc: 15.0 0.000000 -0.009000 -0.007000
cal_abc: 17.0 0.000000 -0.005000 0.000000
cal_abc: 20.0 0.000000 -0.005000 0.005000
cal_abc: 22.0 0.000000 -0.005000 0.005000
cal_abc: 25.0 0.000000 0.000000 0.005000
cal_abc: 29.0 0.000000 0.000000 0.005000
cal_abc: 33.0 0.000000 0.000000 0.005000
cal_abc: 39.0 0.000000 0.000000 0.005000
cal_abc: 42.0 0.000000 0.000000 0.005000
cal_abc: 47.0 0.000000 0.000000 0.010000
cal_abc: 50.0 0.000000 0.000000 0.010000
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 16 16|M.Zuiko Digital 12-50mm f/3.5-6.3

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

niku: I just found your post. I want to give you a belated THANK YOU! Your profile works great and the correction looks good to me. There was a slight glitch getting AfterShot Pro to recognize it, because it already had a "12-50" entry that was uncalibrated.

Thank you again.
