This is a perfect DSLR for all. Picture quality is amazing(definitely not the best in the class). But when it comes to video, it is the leader in the class. Moreover it is having Swivel LCD with touch, that helps a lot. For bird/action photography it is quite capable with 7 fps(in JPEG not RAW). Also you can control this camera from your smartphone(android/iphone with EOS remote app).
Its AF is too good and very fast. For better results, try STM lenses. Overall Its all-rounder camera. It may not produce images as sharp as Nikon D7100 but if you consider all the features provided by 70D(like better video, AF, faster), its the best semi pro DSLR. Go for it, its a complete package.
