Hi guys, I have shot full frame Canon EOS for years and my main camera is my trusty EOS 5D MkII with 24-105mm f4L, 35mm f1.4, 100mm macro, 200mm f2.8L, 300mm f4L, 85mm f1.8. I am considering upgrading to mu43 when the E-M1 MkII is released and I would like the opinions from people who made similar switches from full frame to mu43. There are four aspects of the change that concern me: 1. Bokeh. Background blur on the longer lenses doesn't worry me as the effect is easily achievable on mu43 lenses. However, I love using the 35mm f1.4 on my 5D as it can make subjects pop out from the background. The closest mu43 lens that could give me anywhere near the same effect is the Voigtlander 17mm f0.95 but the image quality of that lens doesn't look too great at max aperture and I would be lumbered with manual focus. Any advice or workarounds from anyone? 2. Tracking AF. I also have an old Canon 1D MkII which has killer AF for birds in flight. I know the E-M1 won't be as good but do any of you shoot birds in flight with the Olympus cameras? 3. Power up time. With my DSLR, a quick tap of the shutter button means I am instantly in action (very important for street photography). How fast does the E-M1 wake up from sleep? 4. Ergonomics. I have large hands and I love the way the EOS cameras handle, especially the dials for shutter speed and aperture which need to be adjusted quickly. The positive clicking motion of the dials confirms that adjustments are happening. How does the E-M1 compare? I have had an E-PL5 for a while now and I like the images from it but the small controls are far too fiddly for it to be used seriously. It's a great camera for travelling.
