Reddit reviews B+W 77mm Circular Polarizer with Multi-Resistant Coating

B+W Polarizer when I've got sky/water that I wish to accentuate (or glare I need to rid of).

Tiffen Variable ND filter for run-n-gun stuff.

Breakthrough Photography ND Filter for things I care about.

I actually just invested in a 6-stop breakthrough filter to replace my Tiffen because I was starting to notice more and more unpredictable colorcast (it's still a very good filter). So far it's a vast improvement, but I don't know how functional it is compared to a variable filter... I'm personally hanging onto my Tiffen for some time before I part with it.

Hello fellow photographers, especially, landscape photographers, I have some questions about using a circular polarizer filter along with an ND filter when shooting foliage and water.


My current setup consists of:

• Lee Foundation kit + 77mm adapter ring
  
• 10 Stop ND filter by Haida
  
  
  I put my adapter ring on top of my lens, then the foundation filter holder and then slide in the filter in the holder.
  
  
  I have been eyeing this filter: https://www.amazon.com/77mm-Circular-Polarizer-Multi-Resistant-Coating/dp/B0000BZLAD/ref=sr_1_7?ie=UTF8&qid=1488189576&sr=8-7&keywords=77mm+polarizing+filter
  
  
  The setup would be:
  
  
• The CPL filter which has threads on the outside
  
• The adapter ring
  
• Lee foundation kit holder + ND filter.
  
  
  
  My questions are:
  
  
• Will it cause too much vignetting with my Canon EF 16-35mm F/4L lens ?
  
• How can I use the same CPL over my Canon EF 24-70mm F/2.8L lens ?
  
• Is CPL even a good idea when shooting water and foliage ? Some sites say they are indispensable while some are saying one can do without them.
  
  
  
  I don't want to spend a fortune on a Lee square CPL filter and would like to stick to a screw on filter.
  
  
  

Just order a new CPL. Amazon prime with free next day shipping. We're only talking about $70-$80 for halfway decent CPL.
