Matt Granger has posted a short hands-on video and samples gallery for the new Canon EF 400 f/4 DO IS II. Keep in mind the lighting conditions around the Canon booth are less than stellar and all the sample images were shot at high ISO.
I had a chance to hold the lens and it feels exactly like the previous version, solid, light and well balanced. I am looking forward to shooting with the new 400 DO, as the first version is one of my favourite Canon lenses.
