UWA micro four thirds format
« on: August 10, 2018, 10:44:20 AM »
hi everyone, i'm looking for a clarification please.

i have the standard edition of Photoscan.  on the manual it states that it is best to "avoid ultra-wide angle and fisheye lenses".

on these forums though i have read that using UWA lenses, and even FE lenses can be a good thing.

i use a Pen-F and an EM1 (micro 4/3 sensor) to take photos and have both FE and a 7-14mm (14-28mm 35mm equivalent) wide angle zoom, which i plan to use exclusively @ 7mm as the manual states to use zooms at min or max focal length only.

is it a problem to use such lenses?

Hello SandroS,

For the images with the obvious fisheye distortions you can switch the camera type from Frame (default) to Fisheye in the Camera Calibration dialog prior to the image alignment.

thanks Alexey.

so FE can be used as well then - that's good news and i will definitely try it.

how about the 7mm FL/micro four thirds sensor?  can PhotoScan deal with that out of the box or do i need to calibrate at all?

actually i've used that combo before and it seems to work well but would be good to get official confirmation that there are no known issues.
