Thanks Klaus! This lens has always made me curious since the announcement and your results are very promising.
Can I repeat the request made in the posts above?
Performance with teleconverters would also be interesting to many of the intended users of this lens... Sigma or Canon, putting a 1.4x TC on this to make it a 180-420/f4 is very attractive... but the question is , how does the quality hold?
Thanks,
