Well I had a bit of an unusual experience last night, went to an Oval Race meet (nothing inspiring, Rookie Rods, but my step-son and his cousin compete so had to go along), and came home with 1,800 photos (par for the course, doing lots of burst mode shooting), and usually I'd expect to throw loads away as out of focus or too blurry, especially the slow shutter speed shots I (try to) take.
However, just loading them into Lightroom now and I've got way more keepers than I expected.
Either I drank some magic skills potion last night or the CA-F performance of the EM1.2 + 40-150mm f/2.8 is much, much better at the wide end. Really should start using those ND filters I suppose!
