It happens! I think the general problem is that it's somewhat difficult to make a super-fast prime that doesn't have CA, especially at hard transitions.
But 135L is still not a super fast lens.. I'm waiting to see some photos shot wide open using this lens.
Guys, if you can, PLEASE post the pictures of thin cables and see how bad the purple fringes are.
If this is a lemon, I need to get this fixins quick by sending it in tomorrow hopefully I can get it back before any important event which is coming up next month. Thanks again.
