By the way I think there's a lot of sample variation on the Nikkor 70-200 VRII; as there was on its predecessor. The one Nikon replaced mine with has been very good, even on the D800, very close to the class-leading Canon and in practice better than the Canon can achieve given Canon's current sensor limitations. My assumption is that the only thing really holding Nikon back on this lens for now is the narrowness of the lens mount; Canon has the luxury of putting a bigger rear element in there which solves several problems.shorebreezehttps://www.blogger.com/profile/06294498793482502897noreply@blogger.com
