Here we have a compilation of some of the footage I've captured using the Panasonic Lumix GH4 and the Panasonic Leica DG 25mm f/1.4. As you can see, depth-of-field is very smooth and noticeable. I will go into further detail in a review in the near future, but the DOF is a bit TOO much for me with this lens, leaving the subject not as sharp as I'd like in low light. As seen in the shot of me, however, given the right lighting, this lens is a star!
