I would first like to qualify the comments that follow by saying that I really appreciate your reviews and insights, they are informed and very valuable and I always look forward to reading them. That said, I can not help but notice that what was categorised as a "minor quibble" in your a7s review 15 months ago is now called "pixel-binned mush with moire and false colour". I quote this not as a criticism of your comments, but rather as proof that I feel that Sony has already become a victim of its own success. Maybe it should put the brakes on the incredible pace of its camera development, because what was "the best sensor I have ever shot on" last year is so quickly superseded. Given the incredibly rapid advances in technology that Sony can bring to market, it really is a very important question for professionals and enthusiasts alike as to whether we should keep upgrading or hold on to what we have. For years we had the same thing with stills photography and the sensor resolution "arms race". Thankfully common sense is just starting to prevail. Perhaps we need a similar reality-check with video? After all, how many people buying video-capable cameras really do need to shoot 4k professionally? For me personally, my a7s mark one will serve me well for years to come, and I relish the opportunity in the very near future to pick up a backup body at a bargain knock down price!
