Well, I've been wanting a full frame camera for years now. Despite being a professional, all of my amateur friends have much better cameras than I do, reason being I've had to equip 3 photographers, so there's nothing left for my own gear. But now I've saved up money and I was about to order the D600... but now I'm thinking about the GH3. The D600 is a great photo taking machine but I'm sick and tired of "1080p" video that's actually 720 or below. The difference in video detail between the GH2/GH3 and D600 is absolute night and day. If I'm going to be traveling around the world, shooting things that I may never see again, I sure as hell want that full 1080p of detail. So some questions, because I know new to nothing about the GH3 and 4/3rds systems. How's the dynamic range and ISO performance? It seems from reading reviews that the ISO is at least as good as my Nikon D300 (ISO 1600 is usable. ISO 3200... not so much.) And the dynamic range? This is super important for landscapes and shooting interiors. GH3 only brackets 7 images, which may not be enough (I usually bracket 9 images 1EV apart). The D600 seems to have so much dynamic range in a single RAW that bracketing may not be necessary. Basically, is the GH3 just as capable of a photo taking machine as my D300, at least?
