wait for next generation. like A6100 or A7000 or whatever. both panasonic and canon is locking some of the advanced features from their lower-end camera. Sony should be able to see that market gap. things like S-log 2 and even 3 may be included in the new camera. Sony is not afriad of introducing the most advanced tech into mid-level camera. e.g. A6000 had the most advanced hybrid AF at the time of launch.
(i have A6000, i think video for 1080p is great, but still no match to 4K downsample to 1080p that A7s or GH4 can do. so hopefully the next A6000 will have 4K)
