Home made lens align tool

Ready to be put to the test after building today....Results: for the Canon 6d And some of the older lenses micro focus adjustments were needed. This turned out to be a useful exercise. The 300 f2.8 back focused, the 150 macro front focused, the 135 focus was also off. The 14 to 35 was dead on and the 24 to 105 stm was pretty darn close, only at bit off at 105mm. Both the Sigma and Canon 50's were slightly off. All good now. What was interesting is the 6d
allows seperate adjustments for wide and tele
on zoom lenses. Very cool.
