Hi, Haven't found much on the web about the nodal points of Mu43 lens so did my own measurements shown below. Problem is these are accurate to maybe 2-3mm. But so far, I've had no problems stitching photos using Olympus Viewer 2. Have yet to get a heavy duty pano program. I'm wondering if anyone else out there has made their own measurements so we can compare. The distances shown below are measured from the middle of the camera tripod socket to the pivot point on the tripod. Don't know if the formating will hold when I post this but here goes: Lens FL Z.M 9-18mm 9 mm 85mm 11 mm 77mm 14 mm 76mm 18 mm 76mm Lens FL Z.M IIR 14-42 14 mm 75mm 17 mm 73mm 20 mm 72mm 25 mm 68mm 35 mm 70mm 42 mm 75mm Lens FL Z.M 40-150mm 50mm 60mm 75mm 50mm 100mm 50mm 125mm 50mm And for the Z.M 12mm F2 = 48mm The Pany 45mm Macro = 55mm Its interesting that the WA zoom has the longest nodal point distance. That's what an inverted tele gets you I guess.
