\"stars look like sliver moons anywhere at all near the borders anywhere near wide open, sorry\"
That\'s one thing holding me back from upgrading my 24L Mk1 to the new Mk2 for astronomy. The images I\'ve seen using the new lens at f1.4 do have slightly sharper stars across the whole image but you are going to need a very, very large print indeed to see the difference, and as you say the corner coma effects are still pronounced, as is the vignetting which is apparently worse on the Mk2. I think I have a good copy of the Mk1 and I doubtful the Mk2 is going to be £1000 better than my older lens, which is the difference between the secondhand value of my Mk1 and the massive UK retail on the Mk2.
Still, I do read all the new Mk2 threads avidly, but suspect I am going to save my pennies for the 35L Mk2, as I don\'t already have a 35mm at present this should give me more bang for my buck.
