I'm torn between Breakthrough Photography (BP) ND Filter and Lee filters.

  1. Is the quality of BP ND filter is overhyped? Would you choose BP over Lee or vice versa?
  2. Can I stack the two circular version of BP ND filters? (e.g. 3 + 6 stops)
  3. Finally what's the difference between BP X4 and X2 version of the filter?

    Unfortunately, this question is too broad. Question #1 is primarily opinion-based, and would probably be closed as such if it were its own question. #2 would probably be closed as a duplicate (What's the result of stacking ND filters in terms of total stops?, Will stacked ND filters perform as well as a single 10 stop ND filter? ). – scottbb May 15 at 13:36

    If you're going to invest heavily, I'd actually advise you look into the 100mm square systems. Find the system mechanism that you like working with the most (it helps if you can try them in person) and then, if you don't like a particular brand's filter, it get's pretty easy to return and try another's using the same rig. The diff in X2 and X4 is in both the glass and coatings. The X4 appears to be higher quality (I have no direct exp. with it) – Hueco May 15 at 18:55
  • There's pretty much no way to make this not a shopping question, other than asking "What is the difference between A and B? How will those differences affect the usability of A versus B?" – Michael C May 16 at 2:38

    "Is the quality of BP ... overhyped?" Since pretty much all of the hype comes from BP's marketing department, probably. The entire line of BP filters are decent filters, but there's nothing about them that is a true breakthrough. Their earliest products had a knack for finding the sweet spot between price and performance (i.e. finding the best level of performance before the rise in price really begins to go up exponentially for a modest additional improvement in performance). Now their products are even better performers, but are almost or just as expensive as everyone else's. – Michael C May 16 at 2:43
