I would like to create a gigapixel panorama with my phantom 4. The problem is the lens. To create a nice gigapixel pano you need a program like Litchi, a software like ICE but also a lens with a narrow FOV. The stock lens is 94 degrees fov which is perfect for flying but not to create gigapixels panorama. So at this point I want to replace the lens with a way more narrow one. The lens thread is a common M12. The problem is that I can't really find any lens with at least 25mm and 10 megapixels quality. Most of the 25mm ones are 5mp. Not sure if someone knows where to get a nice 25mm lens with 10mp at least or any other solution. I am looking for a very narrow fov with high zoom. This will allow to create a very nice gigapixel pano shooting 40/50 photos per each level on 5/8 levels or more. Thanks!
