CPL for 17-40

[Roy C]

I am thinking of doing a bit more landscape stuff and was considering a CPL for my Canon 17-40 which would be used on a 1.6 cropper (7D). I have a few queries which I hope the experts could answer.

1. Is a CPL worth getting on digital or could the effect be replicated in processing?

2. Which CPL would you recommend for my combo of lens and camera?

Thanks in advance.

The effect of a polariser is one of the few filter effects that can't be recreated in post so yes, very worthwhile.

As you want it for landscapes I would (and indeed did) buy the Lee 105mm cpl, you'll need the adaptor ring to go with it too and either a foundation kit if you want to use it on its own, or the pro kit with two holders if you want to use it with other filters such as ND grads. It is a whole heap of money but the best solution for landscapes, you can use the polariser to cut down on reflections from a lake for example whilst still using a grad to pull back the sky and both can be angled independently. You've got a good lens, it makes sense to use good filters with it.

Thank you Mark, what advantage has the Lee system got over a screwing type like the Hoya HD CPL ?

The main advantange is that you could use an ND grad (or other filters) at the same time.
