So by now some of you may have been fortunate enough to secure you very own Leica SL since the November 16 retail release, and I bet there are some excited people out there wondering how well this camera performs – more so over time, and not in an 'extensive' five-minute test. The initial reaction from the market was both positive and maybe a little overwhelming, with many expecting a more compact amateur-based camera. The specs indicate otherwise - a professional mirrorless camera, and that is exactly what the SL is. In fact it is the world’s very first professional mirrorless camera/system. It’s unlike anything we have previously seen, filling the gap left from the R-series, and it’s taken the market by surprise.
