Hi all I've searched but was unable to find anything that dealt with all the questions I had on this... I have GW and GSW690 rangefinders but have yet to use any filters other than the UV filters I use in place of a lens cap to protect the lens. I understand that using filters, particularly grads and polarisers, can be a bit of a challenge with a rangefinder for obvious reasons. First question - which system? Would Cokin P with a 67mm adapter be sufficient with the GSW (65mm) or would I need to go bigger i.e. Z-Pro? I don't have budget for Lee or Singh filters. Cokin say P for 28mm+ which I believe should just be sufficient. People complain about having to guess when lining up ND grads but surely if you're using square filters it's relatively easy to determine how to orientate the filter according to the landscape? Polarisers I imagine are going to be more challenging. Primarily I'd be using it to reduce reflection in large bodies of water. In theory I could look through the polariser until I found the correct position then place on the lens in the same orientation but perhaps in the field this just isn't so practical. Sometimes I wish I'd just bought a D800..! Thanks in advance.
