> Hi Steve, thank you so much for the terminal assignments and I apologize for the tardy reply. I learned today I'm leaving asap on a work assignment so been tying up loose ends and I didn't have a chance to go to the hangar and unmount the EM3 and take photos. My email is alexandre.molteno AT gmail.com and it should handle the file size ok I think, I appreciate the help so far!
