Yes, for sure.... I am beginning to dream Canon again... I'm hopeless! :-C
I found that I had a considerably higher keeper rate with flight shots with the Nikon, especially if I was shooting burst mode. Had a lot of Avocets flying around cursing at me in Germany. One afternoon I shot 600+ shots with the E-M1+ Canon 400/5.6 USM, naturally MF, and 18 (!!) were really sharp, and only two ended up being good shots. With the Nikon and the ancient Nikkor 400/5.6 I had 5 or 6 times as many keepers, but the lens is not as good as the Canon lens, less contrast and much more CA. The EVF flickers too much and blacks out during burst so it is very hard to follow, not to mention focus. Especially hard against the light as birds in flight so often are. As you said, wrong tool for the job. Autofocus?...more like outafocus!
Still looking for that big 500 f4 prime then Dan
