What do we think?
I have posted our initial impressions of the new Canon EF 600 f/4L IS II. My professional outdoor photographer friend Ethan Meleg took the lens for a day to see how it performed.
As with all reviews at Canon Rumors, there's absolutely no technical stuff. We just try to tell you what we think about it in real world situations. There will be lots of pixel peeping coming in the near future I'm sure from the sites that do it great.
We'll update the review in the coming months, we just haven't had enough time to put it through all the various situations we might use a 600mm lens for.
