At a glance, the two cameras are very similar in appearance as the NEX 6 borrows most of it’s styling cues from the NEX 7. They’re both the same approximate size and each have a touch screen and the same excellent built in EVF, but the NEX 7’s tri-nav dial system is replaced by a single nav dial and a mode dial on the 6.
Under the hood, the NEX 7 features a 24mp CMOS Sensor while the NEX 6’s sensor is only 16mp. This would seem like and advantage for the flagship, but Sony somehow seem to get a lot more performance out of the 16mp sensor on the NEX 6. Rounding out the features comparison, the NEX 6 is also equipped with Sony’s new Hybrid Autofocus system, a standard hotshoe and Sony’s new Wi-Fi and app system. The most glaring omission of features from the 7 that was left off of the 6 is a microphone input jack.
These are both phenomenal cameras, but if forced to choose between the two, I would have to agree with Matt – the NEX 6 is the way to go. The NEX 7 remains Sony’s flagship of the lineup… for now. But while the NEX 6 technically fills a spot between the 7 and the new Sony NEX 5R, with it’s new Hybrid AF, Wi-Fi and app systems, the NEX 6 is currently the most advanced NEX camera to date.
