Actually, we have what
«collimnation is not needed everytime you change the mount... a collimnator is just used to adjust your back-focus if something gets knocked out of alignment.»
Hi Emanuel,
With all due respect I don't agree with that statement. With a 35mm lens at F5.6 it is unimportant, but an 18mm @1.3 is a different story.
In any case how would you know after changing the mount that it had not been knocked out of alignment by 1 apec of dust?
