I just wondered, some stuff I read suggests Linear polarizers are still perfectly fine, in fact may even be better than Circular in certain conditions. I realise that using a Linear can throw exposure off, and then also if using AF make that aspect wonky... but if your sole intention of using a polarizer is landscape, tripods etc, then does it matter about circular?
Like... when I do landscape anyway, I'm tripod for long exposures of water or clouds, or I'm using Pixel Shift. All of this means I chimp after the shot to check exposures, focus etc, so if Linear throws exposure or focus off... after I chimp once I can just accommodate easily enough for it? And all my landscape tends to be Manual Focus, either to infinity or Hyper-focal stuff etc, I just use Live View for it all anyway...
Not only are Linear cheaper (significantly) but I read some say they are better (than Circular)? If using a Linear for landscape, and a fairly wide focal length, does Linear produce a more even blue sky across the frame more than circular?
I'm just trying to think of all the occasions I'd need to rely on AF with a polarizer attached and be concerned with correct exposure. I'm currently shooting exclusively manual focus and actually enjoying the results a lot, exposure wise I tend to underexpose anyway and shoot RAW to deal with shadow retrievals etc.
