Hello everyone

I have just bought a Canon YJ13x6B IRS lens for my XDCAM F350. I could afford a HD wide angle 1/3 lens with extender, so I got an SD one. I don't thinks my clients will notice any difference.

Is anyone out there using a Canon yj13x6b IRS wide angle lens with perhaps a UV filter or a circular polarizer? If you are which ones are you using? Is the filter diameter I need 85mm?

I know it sounds silly but I can't see any screw treads on the front of the lens. Can you screw filters onto the front of this lens or do you have to use a matte box to hold them?

Thanks for your help as always!
