I currently own a Canon 60D - 28-135mm EF Lens, along with my newly purchased Benro A-2691 tripod and Vello Wireless remote. But am now looking at filters - after searcing the internet I've not seen many reviews on filters and what is good and bad. I'm still a novice but now know that I need some filters (Polarise) for outdoor shooting. So this is what I know - I need a circular filter so that the autofocus can work and that there are some big price differences between one and the other (I've been buying from ). So I'm looking for some advice from those that have tired and are happy with what they are using - any negative or positive attritubes would be greatly appreicated.
The lens is a 72mm but I'm also looking at two lens as well.
Canon EF 100-400
Sigma 150-500 DG
The filters I'm looking at next month - the Lens - well - maybe a christmas present to myself :-)
