I spent the last week in September at Chilko Lake in BC photographing grizzlies, and a few eagles. It was an incredible trip. It was lead by John Marriott, who is an outstanding outdoor photographer. The trip was timed to coincide with the salmon run. We were seeing 20 to 30 bears per day, including many cubs. I was the only one shooting M43. In fact everyone else was shooting 1Dx or 7D mk II bodies with 500mm lenses. I was using my EM-1 with a 300 mm f 2.8 lens. I think I stayed up with the big boys pretty well, but there were a couple of areas where my equipment lagged: A 50 shot buffer sounds great, but it fills pretty fast when you're shooting grizzly cubs play fighting at 10 fps. Once the buffer is full the slow write speed to card is infuriating. I have since bought a faster card, which helps some. I understand that the EM-5 Mk II has a much faster write speed, so hopefully this is the case with the new EM-1. Better CAF would be useful for birds in flight and things like running bears. The EM-1 is good, but it isn't up to 1Dx standards. Of course given the price difference that isn't really a fair comparison. Overall I was very happy with my gear and with the photos. I shot about 35,000 photos (really!, not a typo). I deleted about 2/3 of them right away. I was shooting at a high frame rate, so I many duplicates. Anyways, here are some of my favourites.
