I have just bought the Sigma 10-20mm lens and realised that I cannot use my cokin P size filters with it. These consist of Hi Tech ND grads and a Cokin polariser.
Can anyone recommend a filter holder kit which would allow me to use these without vignetting?
I am coming to the conclusion I need to save up for something like a Lee holder and adapter ( not much more expensive than the Cokin of similar size and cheaper than the Hi Tech ) and using 100mm Hi Tech ND Grads ( good quality and cheaper than Lee).
Ideally I would like to use a polariser that screws directly into the front of the lens, as I always found the Cokin type of thing a pain to use. The only problem is that I suspect that such polarisers would cause vignetting and unless there is an economical wide angle soluion, it seems unikely that that they will be feasible.
I know I could just go for the complete Lee solution but as I said the fiddling around with filters for the polariser is a nuisance and the expense is considerable. I would prefer to stick with this solution for the Grads only
Thanks for your help
