I just bought the DJI Phantom 4 Pro with the new 20MP sensor that can also shoot 4K @ 60fps finally. From what I can tell so far this is going to be a game changer in my Real Estate photography over the DJI Phantom 3. I will be doing a full comprehensive review on the DJI Phantom 4 Pro I am just going to need about a month with it so I will be able to give a amazing review but my first impressions are very very high so far. You'll need to make sure that you have a U3 Micro-SD otherwise you will not be able to shoot in 4K also I am using the new iPad Mini 4 which has a 7.9 inch screen which is a little bigger then the monitor that you can get with the DJI Phantom 4. One thing I can say with 100% confidence is that the DJI Phantom 4 Pro has a amazing battery life it is really close to what they claim I was getting around 26-28 mins per battery which I was only getting around 21-23 mins per on the DJI Phantom 3 which 5 mins doesn't sound like much but it truly is huge!
