I have a Canon 70-200 L lens, an 18-55 kit lens and am now looking at a Canon 100mm L lens.

Can anyone tell me if they use a UV filter for protection.
I have seen these two advertised form DDP on the net. Hoya Super Pro 1 Multi-coated UV Filter and a Hoya Multi-coated UV Filter.
There is quite a difference in price though.

I know I will need to also get a circular polariser filter as well, but will hold off a little bit on that.

I have read so much on the pros and cons of using a UV filter. It seems quite confusing.

Thanks
