EF 800mm f/5.6 L IS
EF 600mm f/4 L II IS
What's your take on the suggestion, which seems to be backed up by TDP's ISO 12233 crops, that the 600 II with 1.4x III, which is 840mm f/5.6, is optically at least as good as the 800mm f/5.6? The 600+1.4 would also be much lighter.
Hmm. I hadn't read TDP's review of the lens yet. I'll have to check it out. I guess I'm a tad surprised...the 800mm lens is still one of Canon's newer lenses (from 2008 or 2009?) I would have figured it was just as optically superior as the 600 f/4 II, as the 800/5.6 was kind of the first lens in the new generation of 4-stop IS telephoto lenses. If the 600+1.4 is just as good, well sure, I'd skip the 800mm.
