I went on a tour of the James River this morning a little east of Richmond near River's Bend with some friends. We saw upwards of 10+ bald eagles, many osprey, a great horned owl, and a blue heron, among others. These were all taken with my Oly EM1 with 40-150/2.8. I must say I was a little disappointed at the keeper rate and C-AF. I had many runs where the bird was dead center in the frame and not a single pic was in focus. Keep in mind, we went out at 7:30 this morning and it was overcast so there wasn't great light. But, my friend with a Canon 5D Mark III was nailing them without too much difficulty, even the first shots of the morning before the light got better. I did find I got more success by pegging the ISO at 1600 early and then 800 later and keeping the aperture wide open to keep the SS over 1000. So some of these are taken at the extremes of the 40-150 lens - wide open and at 150mm. In poor light. Also, there were many shots of birds with trees behind that confused the autofocus. Then I resorted to manual, which is not easy! Still, I did get some nice shots. I did learn that I need to really close crop the bird in flight as best I can, not only to maximize resolution, but also to greatly improve focus. My keeper rate got better towards the end, but I still think the EM1 is just OK for BIF. Hopefully the EM1 Mk2 will be much better. I hope you guys enjoy them!
