On full frame sensors, I like the 20-50 range when on the Movi. Keep in mind that when using a wide angle lens on the Movi, you run a greater risk of casting operator shadow on your subjects. With wides, you usually need to be closer to your subjects, meaning light sources should be higher. If you are on a tighter lens, you will naturally operate from a few more feet away, thus making the operator shadow not as much of a problem.
Dailey, as with normal photo situations, it completely depends on what you’re shooting! I use virtually all Canon lenses, depending on the situation. However, one thing to consider is weight, and as such, the 15/2.8 fisheye and 24/2.8 IS are very light.
Dailey we use the 24/2.8 IS lens for normally but if we want a wide shot we bring out 15/2.8 fisheye instead of doing 3 photos you can do it in one!
