Well, I think I'm finally getting into the groove with the E-M1. Last week, I added a 75/1.8 to the lens collection and I can say with no reservations I really love this lens! As many others have said, it's easily among the sharpest lenses I've ever used. I think we are going to get along just fine I'm also feeling a bit more comfortable with the capabilities (and limitations) of the new body. Continuous focus (IE; servo mode) is really bad. My keeper rate for those attempts was very low. That said, the ones it did nail it did so admirably. Single focus mode was fast, but often not fast enough to keep up with moving amateur players. I am honored to do some volunteer work for Special Olympics. The Southern California branch recently held their Fall Games, which is the last big event before the World Games in Los Angeles next year. For sports, I have a strong back ground in bat & ball sports at all levels and was hoping to shoot some softball, but we go to where the need is. I've never really shot tennis before, but there I was. I shot the day using the E-M1, the 75 and the 12-40/2.8 next to a Mark IV with either a 300/2.8 or a 70-200/2.8. Here are a few shots that I think show just how capable the Oly combo can be. With the exception of 1 of these, all images are SooC except for crop. Reach of the 75 was limiting at times.
