I've seen posted in multiple places people complaining about the performance of the 70-200 f/4L IS near the minimum focus distance.

Do owners of the lens on the forum find that to be true?

I'm using the 135L presently, but am thinking that, while it is a wonderful lens, perhaps I'd be better off considering the 70-200 f/4L IS to expand the versatility while maintaining the excellent image quality. Poor performance at MFD would definitely shoot that idea down though...

Thanks in advance. I'm not considering it really seriously yet, but it is on my mind.
