I've been using the Sony Nex 6 for a few months and I have enjoyed the experience. Let me say that in certain circumstances I have no doubts that these types of cameras are capable. In fact, they are more than capable in most situations. For most picture taking situations mirrorless cameras perform very well. For sports shooters or wildlife enthusiasts these may not be the cameras for you. So far, I taken sunrise and sunsets. My recent trip to the HRADA car show and the photos I posted the last two days were taken with the Sony Nex 6, wirelessly uploaded to my iPad and processed with Snapseed. I love my Nikons but the Sony has become the daily companion that I travel with. More to come soon.
