Canon 7D + Sigma 10-20mm
I'm getting stitch errors with this combo. I've tried upper rail settings of 104, 102, 101 and 98. The 102 & 101 I got from camerasettings.html with a 40D/30D. The 98 from a post in this forum when I did a search and the 104 I got from my own determination of the NPP. I'm using PT GUI and I'm overriding the Camera / Lens parameter in the Project Assistant to a lens type of rectilinear, focal of 10mm and I leave the multiplier alone (1.613). Anything I've left out? Thanks.
