    Which Super Telephoto ??

    Vespo, all, The 800/5.6 is certainly an awesome lens with a killer MTF chart! Good review and analysis here: https://photographylife.com/reviews/nikon-800mm-f5-6-vr though at a minimum of 4.6kg it's going to be a strictly dedicated setup, and the concern is that even then reach will not be...

    Which Super Telephoto ??

    Thanks to Geoff, BodyResults, Leo, and Binoseeker again, as well as everyone who has replied previously - your input is greatly appreciated :t: Frustratingly, I was so busy that I missed last season, and might not get much time this year either :-C On top of that I've injured my good...

    Which Super Telephoto ??

    Thanks Hermit, that's a very useful practical demonstration, and the type of thing I was looking for :t: A friend's 7D II shows quite a few different wing positions on most birds that I don't usually get. As Thomas showed, it's all about the frequency of wing beats vs fps .... If one is a...

    Which Super Telephoto ??

    Thanks for the reply Binoseeker! That site is useful for the Canon stuff, though less so for Nikon - I couldn't get the links to the D5 review to work, and the new FL lenses are not on the comparison tool. I'm still very interested in those that are actually using the Super Primes (especially...

    Which Super Telephoto ??

    Better photos needed! Super telephoto Prime on the horizon? Serious thread. Seriously long post. Seriously impossible dilemmas. Help much appreciated. A lot of this will ultimately come down to trying various options, but I am really looking for your first hand experience and methods from...
