I shoot a lot of classical music. Gh2 got old and I've tried bmpcc and nx1. Both produced aliasing beyond the gh2 levels. So I need something less prone to aliasing and moire. Specifically black lacquer pianos and the line of reflected light alias at every setting. Strings also an issue. Would love 4k in camera so looking at the pannies. Would the zx1000 or g7 be a wise buy in view of my requirements? Nikon 5300?
+1 for GH4. You will get 0 moire in 4K.
Stair-stepping on strings is a big problem for classical music. To really get rid of it you also need to avoid certain angles. The ax100 is certainly good, but you will see a tiny, tiny amount. I just happen to like the ax100 for classical music as having the right balance of features, including handling spotlit venues, the color, the aliasing, etc. You get more resolution then the GH4 (useful if cropping and panning in post), less aliasing than the GH2 and better color for classical type outfits. Skin tones are almost as good as Canon, if you like Canon, some don't. I find that out of the box the Panny color leans towards pasty. You can rent these for a weekend to try them out. The GH4 is certainly an OK choice as well. The Sony takes cheap monster batteries, should you care about such things.
Go with the G7! I have handled and shot with it, and it is a beautiful camera! The sensor is the one from the GX7 but looks almost exactly the same as the GH4, but has less bitrate options, and no slowmotion.
