Excerpt: For bird photography this is the bomb. Insanely sharp, focuses quick, the 1.25x teleconverter (included and mated for life with its partner 800mm - they even share the same serial number - I know old fashioned but true) works great. As long as you know the limitations of super-telephoto lenses this will be your Dreamboat Relationship. However if you haven't shot 500mm and longer lenses there is a steep learning curve.
Pros: Consistent Output, Fast / accurate auto-focus, Nice Bokeh, Sharp
Excerpt: I use it for landscape and wildlife. Nikon case and overall quality is excellent. The soft lens cap is the worst I have ever seen in 50 years years of experience. It is hard to work with and does not seal well. I have replaced mine with a shower cap that is far superior in terms of cost, ease of use and effectiveness.
Pros: Fast / accurate auto-focus, Strong Construction
This lens will take your peeping tom game to a whole new level!

Summary: I mean, just look at this lens. You can tell by looking at it that it will take your peeping tom game to a whole new level. No longer will you be limited to your immediate neighbors. If there's someone several houses down that you've been meaning to get "better acquainted" with, this lens will help you accomplish that. When you first start walking around with this lens, people will ask if that's a new lens on your camera, or if you're just happy to see them.
Excerpt: I just got the 800mm….I haven't used it on a "working" trip yet but I have played around with it a bit on some birds. It's extremely sharp, is very fast focusing, and it's lighter than my 600mm !!! What could be better? I can see it will be a great bird lens but my primary purpose is for all wildlife, and for that I'm sure it will excel.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Rugged, Strong Construction
Excerpt: There is no reason to hesitate buying this lens. If you are wondering if the image quality measure up to Nikon's other lenses...it does. I have been using it with a D800 and I can't get over the detail that the camera/lens combination is able to resolve. The Vibration Reduction works as advertised. I have shot this hand held and was happy with the performance. The lens is light for its size.
Sharp sharp sharp! But make sure you update your firmware.

Summary: For the longest time, Canon users could brag about their camp having about the longest production lens in their portfolio, the Canon EF 800mm f/5.6L IS USM Super Telephoto Lens for Canon Digital SLR Cameras . Now, Nikonites finally have a cannon of their own (though at ~$5k more than Canon's), a true flagship in their supertele line up. Let me be honest here. I don't own this lens. I feel very few private individuals do.
