I have reviewed the Hoya S-HMC and the Singh-Ray Vari-ND products. I think that the VARI-ND will suit my needs just fine, but it's really expensive! (I think I would rather invest 340 on or towards a great lense!)
Will the Hoya S-HMC work for shooting soft-looking waterfalls and streams?
Really need some solid advice on this, but I have perhaps been asking the wrong questions on polarizers.
