I enjoy taking pictures with fast primes wide open. I love the background blur/bokeh/subject isolation/3d effect. I currently have a GX1, have had an E-M5 and am conscious that I keep hitting the max 1/4000 shutter speed on very bright days. I know that the E-P5, E-M1 and GX7 all have 1/8000 max shutter and the GM1 has 1/16000 - but I'm not sure I want to buy one of those - I think I want another E-M5! How many of you who like fast wide open primes in bright daylight also struggle? Or is it not really that much of an issue?
