Q: 7. What's the widest focal length lens I can use with this matte box (on both FF and S35 sensor, using both stages of filters)? Will it work with a 10mm lens on S35 and/or a 14mm on FF?

A: The answer is...it depends. You notice focal lengths are not listed for matte boxes like this. That is because it depends on the sensor, the camera, the lens and the matte box what will precisely work. That being said, we would say that this matte box should have no problem with an 18mm on Super35 and 24mm on full frame. Depending on all above conditions, wider than those lengths may be possible. However, we would tend to think that the real answer for 10mm on Super35 and/or 14mm on full frame would either be a single filter clip-on matte box or a two filter 6.6 x 6.6 matte box.
