Thank you but not now. Your imaging results are sharp, clear, no parallax issues.
The Canon 5d does not have
LCD SCREEN LIVE VIEW. Which makes it easier to view the two poles.
This is what I see when setting up a NPP calibration. Notice the
black TICK mark on front pole (near lens face) is same thickness as WHITE pole 3 meters away.
I took this picture using my Samsung s7 curve Smartphone pointed into the very small 5d view finder hole.
