I second this. I snagged mine used on amazon for about $300+ as well, and IQ wise, it's the best money on a camera body I have probably spend if thinking in practical terms. Great codec, great picture, workable low-light an dynamic range. Couple that with the speedbooster I placed on the mount, and you have a near-full-frame camera that's an excellent B-cam for the a7s (if not a worthy A-cam on it's own).
