Hi Folks;
I've recently joined this forum because it seems much friendlier than some of the others. It also has a nice blend of gear talk and images.
I just finished testing the G1 14-45 kit lens to find the entrance pupil at various focal lengths for pano stitching. Surprisingly, at least to me, is that the entrance pupil hardly moved at all between 14 and 35 mm FL. It stayed around 55 mm from the tripod socket. When zoomed out fully to 45 mm FL, it moved about 10 mm closer to the camera.
I'm not sure these results are correct. By comparison, when I did this with the Sony R1 lens, I found a noticeable shift as the lens was zoomed, and ended up with 6 different settings between its 14.3 and 71.5 mm focal length.
Has anyone calibrated their 14-45 lens for pano stitching? Any comments would be greatly appreciated.
cheers
Santo
