Here's a Music video I've done during the
Anime Weekend Atlanta 2014 convention in Atlanta in September.
I used a Pentax K-01 with a manual prime lens 50mm f1.4 and a fish eye Rokinon 8mm f3.5.
Also here's a small issue I have with the K-01.
I'm a bit disappointed that the K-01 doesn't give you full manual control on video when you use a manual lens. It gives you the option to select the M (manual) mode for video when it is actually not. Changing the iso and shutter speed actually does nothing on the K-01.
