I'm coming back to landscape photography after 20 years. Years ago, when still shooting 35mm film, I shot in black and white and used solid Nd, red, and polarizer filters, screwed onto my lens (not necessarily all at once).
I've decided I'm going to go with the Lee filter system now (none of my old filters will even fit on my current lenses), but all of the filter options have me a bit confused. I live in an area where I have quick access to wide varieties of landscapes: mountains, prairie, and even desert badlands. Combine the varied landscapes with digital colour photography, and my head is left spinning.
What would your recommendations be to start my filter kit with, and why? I'm using a Canon 24-70 f2.8 ii right now, and I'll be picking up a 21mm Zeiss Distagon as my "go-to" landscape lens in the not to distant future.
Also, why does it seem that polarizers have almost gone the way of the Dodo? I'm not seeing them mentioned much, and the shops I frequent don't carry much in the way of them.
