Good observations, Bright Tangerine matte boxes all will Support 14mm lenses and sometimes wider if you are not actually using filters as you may be able to push the lens further into the opening if you're not using the clamp adapter that fits the lens snugly. There is a small gap between where the filter glass falls and the opening so that might help. I've been told wider lenses may be able to be used, but BT only stands behind their 14mm spec. Bono, you have the Misfit Atom I think, so you might see how far you can go with a filter. Or put the screw-on filter on the lens and only use the matte box as a shade and then it will likely work.
