Samyang 8mm f/3.5 Fisheye Lens Profile for Adobe Lightroom (Canon 7D)

, 11 2011 . 16:02 ()
1 +

Download Samyang 8mm f/3.5 Fisheye Lens Profile for Adobe Lightroom(1 kb)

Before correction:

center, 100%

top-right, 100%


After correction, cropped:

After correction, uncropped:

center, 100%

top-right, 100%

Note distortion at the edges. Sorry, guys it's fisheye, you can't make an omelette without breaking eggs. Usable horizontal FOV is around 90.

Calibration note for Samyang and other manual focus lens. Samyang 8mm does not provide apperture and any other lens data. So, Adobe Lens Profile Creator thought, it is 50mm lens with undefined apperture. The easiest way to provide this data, is to update DNG calibration files with simple script.

set_samyang_lens.cmd:

@echo off
set FocalLength=8.0
set MaxApertureValue=22.0
set LensModel=Samyang 8 mm f/3.5 Fisheye
set LensMake=Samyang
set LensInfo=8.0 8.0 3.5 3.5
set Lens=8mm



if "%~1" NEQ "" (
set ApertureValue=%~1
) else (
set ApertureValue=3.5
)



set ApertureValue=3.5 (insert your actual apperture here)

for %%X in (*.DNG) do (
exiftool -P -overwrite_original_in_place -Lens="%Lens%" -FocalLength="%FocalLength%" -Aperture="%ApertureValue%" -ApertureValue="%ApertureValue%" -LensModel="%LensModel%" -LensMake=%LensMake% -LensInfo="%LensInfo%" %%X
)

Run it from command line in the directory with DNG files, specify actual apperture as only parameter. For example, set_samyang_lens 11.0 will set apperture f/11.0 for each DNG file in current directory, along with other lens data. This script works under Windows. Tell me if you need same script for Mac.
