The setup you've posted is a fine setup if you got a focus puller working with ya. My comment was for the unergonomic nature of the fixed lens scarlet which in their rendering is made to resemble a Dual-Grip DSLR. Given the run n' go application something like that is designed for, ergonomics that will help a single shooter operate the said camera does not seem to exist. All I see are horrible Lego-ish edges that the operator has to interact with.
If straight edge is an ergonomic design, why not make steering wheels with a square cross section instead of a smooth tube? Or how about that dual grip in the Red pic above, why not just make the grips to have sharp edges instead of shapely foam?
