Based on the above-linked video, it is a little soft at 600mm f/6.3 but it does sharpen up at f/8. The Canon 100-500 and Sony 200-600 are said to be a little sharper at their maximum focal lengths and apertures, but the Nikon maintains focal length better than the Sony when focused at 5m distance, and other advantages of the Nikkor include much better image stabilization (see 30:22 in the video) realized in normal mode, it is also slightly lighter. The focus recall feature was shown to be useful e.g. when the bird returns to a particular branch the lens can quickly be made to return to the correct focus. Paton felt he wasn't getting quite as many focus keepers as he would have expected but lower familiarity with the Nikon's AF system and settings may have been a factor. But overall he said the Nikkor is "extremely competitive." ...Show more →
It would be a big disappointment if the lens is not sharp wide open.
Ricci Chera did compare the 180-600 with Nikon 200-500 in a video. His impression was that the new lens was sharper at 600mm than the 200-500 at 500mm.
That would be favorable.
I think some tests using production copies are needed and in this price class and lens type, some sample variability can be expected. However, if the production copies of the lens are as described; ie. sharp at 600mm f/8 then as long as users keep that in mind it can be used successfully and will probably be very popular. Thinking about bird photography, if taking either individual bird close-ups or images of several birds, f/8 may be needed for depth of field anyway. For action shots and/or in dim environments, f/8 may be limiting (but so is f/6.3). For aviation shots I think there is usually plenty of light in the skies and so f/8 may be OK to work with for daylight hours....Show more →
I am hoping that this was a pre=production lens and the final version is better in terms of sharpness. This lens is not designed for "close-ups" and for birding, having to shoot at f/8 leaves a lot to be desired for many reasons.
I was initially a bit sceptical about the 180-600 - the tripod collar ring seems narrow for such a long focal length and I would be using it on a tripod most of the time. However, I can't quite ignore the enthusiasm expressed in Paton's video and it seems a legitimately good lens.
Quite the contrary. The idea is to have a lighter weight longer FL lens which can be handheld in the field. When I shot Sony, the 200-600 was never on a tripod. The same for my 100-500. Yes, hopefully it is a good lens.
I think it is good that Nikon let out copies of the lens to reviewers who are not ambassadors so as to give a fair assessment with pros and cons. This avoids people buying the lens with the wrong expectations.
It's part of a marketing strategy to maximize interest and market share.
