Hi folks, does anyone know, (really know) if the new mk11 lenses, starting with the 70-200mm f/2.8 IS mk11, have a higher resolve than the mk1 versions?
Reason I ask is simple, I've had a 7D for 8 months, and my "standard" lens is a mk1 70-200mm f/2.8 IS, I love it, it just always seems to be the lens I want to use.
Now I'm a self-confessed pixel peeper, and my favourite lens does seem to lack slightly compared to some high end EF-s lenses I've borrowed (zoom and prime).
However, I've been desperate to get a longer lens for bird photography and I'm on the brink of buying either the 300mm f4 IS or the 400mm 5.6.
I'm not after arguments for or against either of them I'm just wondering if it's worth waiting for the 400mm 5.6 IS? Assuming it'll have revised glass and coatings too.
My question is this, all these superzoom and super-telephoto refreshes, they're not just for reducing weight are they, they're to increase resolution and sharpness in line with increased sensor resolution?
