The Mirrorless Revolution is just Starting By Steve Huff Well, not with me. I'm not interested in the Sony A7* stuff anymore. I already have a great full frame system, I dont need another. If I go mirrorless, I think I will probably go for Fuji medium format. Assuming the rumors are true and its indeed coming. And about the title of the article - well obviously its "only starting". - All existing systems leave something to be desired, though it looks like Fuji will soon be quite complete as a system (introducing HSS with their flash units and hopefully more flash features soon), though they still have other issues (autofocus performance, affordable lenses, battery life). - Ignoring Leica's high price offers, we only have a single system thats offers full frame (Sony FE). Theres some that offer APS-C but they all have issues: Fuji X lacks affordable lenses, Sony E lacks both in selection as well as quality of lenses, Canon EOS M lacks massively in respect to native lenses, and Samsung NX is gone anyway now though apparently their lens quality was better than Sony. - One of the advantages of mirrorless could be better wide angle lenses. However this requires digital sensors that can handle steep angles of light at the borders. Unfortunately so far this wasnt widely archieved (Leica seems to be in the lead about this, which makes their new SL system even more appealing, but unfortunately not the least bit more affordable). - Even if there was a mirrorless system that would be complete, central issues of mirrorless seem unresolveable, meaning autofocus performance and the fact that EVF needs a constant current, thus the number of shots one gets out of a mirrorless is a lot less (usually around 300; 600 if there is a battery grip) than out of a DSLR (500 for entry level DSLR, 1000 for advanced DSLR, 2000 for advanced DSLRs with battery grip, 3000+ for top DSLR), and thats not considering the problem of shooters that have to use the viewfinder a lot (especially for wildlife). I think a mirrorless could offer compareable or even better AF performance than DSLRs if somebody could make a dualpixel sensor and also use advanced contrast autofocus, unfortunaltey.
