Q: 5. Does anybody have recommendations on a front filter adapter so I can add an ND filter? Something small? Thanks!

A: Sorry, but wide angle lenses need large filters in order that the filter holders are not photographed. B&H does not seem to have a suitable filter holder at this time. However, here is a clamp that may work. http://bit.ly/19azXhK

Q: 10. How would you compare IQ on this lens vs the Veydra 12mm?

A: I would say that the image quality of the Kowa is very good and comparable with the Veydra. While Kowa is not that well known in the still world and recently in the movie world, they are a venerable Japanese optical company that has produced respected optics for generations. I would say that your choice comes down to features. If you are stills oriented with occasional video, the Kowa might be just the ticket. If you will be doing only video, the cinema oriented Veydra set of primes would be good choice.
