So are you just looking for a drone to take aerial photographs and videos of an area? Do you need this to be a orthographic map with lots of stitched photos together? Ie do you need to fly a grid pattern over the area? As that will have an influence on what drone you can use as it will need to fly for a longer time apposed to if you just want to fly around and look at random things in that area.
However if its just for general flying to get some aerial photos/videos then my suggestion would still be the Solo due to the fact that it has lots of autonomous features built in, including the ability to fly grid patterns for survey missions, However a cheaper all in one option is the DJI Phantom 3 Advanced and uses the same camera sensor as the phantom 4. Its also super easy to fly and had 25min flight time with around 5 Km range. It just doesnt have as many autonomous features as the 3DR Solo, but its a fully integrated package so you dont need to add your own gopro camera.
