Dave, I disagree with the Tele belongs to Nikon and Canon. Birds in flight are not easy to catch in general and honestly I don't care wether keepers come from DSLR or mirrorless systems. There' son guarantee in higher keeper rates for me, using Nikon and having only a 300/4 + 1.7 TC. Lack of practise, sure, but in strong winds like here in Wales birds have to adapt to it. Very difficult to predict.


And why didn't I take the 150-600 with me? Beside the additional weight the main reason was: I couldn't finish the AFMA for it. With and without TC 1.4 there are 32 combinations of doc us distance and focal length. I finished most of them, but at infinity things get tricky. Targets in 1km distance won't do for infinity. I need clear sky, it was raining.


Why AFMA and this fuss? Mirrorless could can solve that. I don't care wether I get an image from DSLR which turns out to be out of focus because incorrect AFMAand have to delete it or I don't have to delete it because I didn't get it. And there were at least three situations the camera would not focus at all. So, DSLR as queen of Tele? Not in my kingdom...

  OK JoJu fair do's!

                 You didn't say what mirrorless camera you were shooting with! 

 

    So much AFMA adjustment needed for the Sigma 150-600mm?.............. I have between -1 and -2 dialed in for the Tamron and that includes when I put it on a 31mm extension tube. (macro 600mm, my rattlesnake FL).

 

  Have good holiday!
