So I’ve read a couple of threads on cropped sensors, but I’m still a bit confused.
Does matchmoving software need the original lens Focal Length or the resulting Focal Length after the crop is multiplied?

For example, I’m using a canon 60D (1.6 crop) with a 50mm prime lens. Do I tell PfTrack I’m using a 50mm lens or an 80mm lens?
(50mm X 1.6 crop = 80mm)
Pftrack approximates the lens at 35mm, which is not even close. Syntheyes approximates the lens at 50mm, which sounds right, but I’m not sure if it’s correct.
I’m getting a solid track regardless, but I’m just wondering…
