Have done some tests with the new Phantom 4 Pro that I am using in 2017 for some research projects on photogrammetric point cloud mapping. This is a remarkable step forward in terms of image quality. The Phantom 4 Pro just creates much better image detail and acuity and resolution/sharpness is on a much higher level compared to the Phantom 3A. Its just giving back the DSLR like quality on tiny airborne systems. Also SNR (signal to noise) is much better and dynamic range ist enhanced. Only problem so far seems to be a slightly higher sensitivity to flare but I have to do some more analysis on this one. Its difficult to compare the flare issue because you cannot create exactly the same exposure / image concepts for different copters in the air. It will always be a wee bit different. So some ground based comparison needs to be done here.
This is a game changer for photographers that need an airborne system sometimes. As simple as that. It brings the image quality that we wanted back and you always can add HDR and Pano techniques to add from that. Great times to let your creativity fly!
