Apr 20, 2015 17:37 | #3 I'm impressed. Up to 2 minutes of manual tracking!! They turned out well. I can't do 1 minute with automatic tracking. I'm in Canada. Isn't that weird!

Apr 22, 2015 05:51 | #5 Which 14mm? My 14L has nasty coma. Not sure if that's normal for this lens. It was dropped once and repaired by Canon. But their service record sucks and I would not be surprised if they messed up again. I'm in Canada. Isn't that weird!

Apr 22, 2015 14:11 | #9 Nice captures with that BDT . What is your clock time for turning the screw for adjustments ? You have trailing slightly on your second image . You might want to close the gap some on your clock time .
