I have a pinhole lens for my t3i and it takes some amazing photos. Like all kinds of drawings and if the laser stays still you get a diffraction. I've been meaning to upload some pictures
There are about a dozen laws that the FAA uses. The 1st rc needs to be under 400 feet to be legal. If he is flying that thing over and he gets caught he is going to get NAILED! 400 under under is just what they like the FAA that is. Any higher your in the VFR or regular traffic cordon. If he is any were with in 4 miles of a commercial or civilian field he is breaking the law. Its not safe to fly rc aircraft that high. I have mentioned it to him one other time that he needs to be below 400 ft but what you going to do. http://www.faa.gov/uas/media/model_aircraft_spec_rule.pdf, http://www.rc-cam.com/forum/index.php?/topic/1697-new-faa-regulations-for-uavsrc/ this also applies to drones of any type. helos,quads, ect
