Oh, why did I want that big lens anyway? Bigger filters, a Wimberley gimbal head, a bigger tripod, . . . . .

Sympathies.
I imagine a 112 or 122mm C-POL would cost a king's random indeed, moreso if it's a Kaisseman (i.e. B+W's venerated objet de art). I have always been much aggrieved at the high cost of smaller by comparison C-POL filters ie. going from 67mm to 77mm incurred a $39 increase! Fortunately, only once bitten: step-up/down rings are used to good effect now.
