8mm Rokinon Manual Fisheye: Modify lens database?

by ChandlerBob » Wed Apr 30, 2014 9:09 pm

Reading the documentation for stitching a spherical pano (to be used later in PTP 2) I don't see a way to manually adjust the "assumed" focal length of 50mm for my 8mm Rokinon manual fisheye lens. Without being able to adjust for the manual fisheye lens, the resulting spherical panos are a real mess.

Using PTGui, I can specify the lens parameters manually. Does anyone know how I can go about using the Rokinon without file EXIF data in APG 3.5? I was excited to read about the improvements in APG 3.5 after receiving the Kolor Newsleter, but I'm unable to get usable results at present. I'm stuck!!

Thanks in advance -- Regards, Bob (Arizona, USA)

BTW: Using Nikon D-300, aps "C" crop factor 1.5 with NodalNinja Pano Head

You can force the focal length and lens type values in the absence of EXIF data using the Global settings, or you can manually edit the focal length and lens type in the group Image properties.

Thank you so much! Obviously, I didn't dig deep enough (embarrassment showing through). Nice screen shots! Very helpful!

Regards, Bob
