I am wondering the same thing as the threads on the HF100 are not very deep.
Anybody else try to screw on any filters on the HF10/100?
I am going to buy a step up ring (37mm to 43mm) so that I can use just one size of filter(43mm) with both this wide angle converter and without. You may want to try a 37mm to 37m step up ring as the threads should work much better with your Tiffen.
Well, here's the thing. I never knew much about filters, and I had no idea that with the circular polarizer, you were supposed to rotate it to achieve different results. I should've thought about it before, but I have no experience with filters. So after I accidentally discovered the way it works, I'm more than happy with it. The problem is that it's still a pain in the butt to screw it in, because of the narrow dented ring, but also because the camera threads being so narrow and even worse, plastic, something that baffles me. I think I already deformed them a little bit while trying to put in the B&W ND 0.6 filter, and I think that after several times of screwing the CP in and out it's going to get deformed, even being extremely careful. I'll probably just leave the CP on all the time. I just need to get a cap to protect it. If I use the 37 to 37 step-up ring, would that cause any effect on the picture quality, since the CP would be a few mm farther from the camera lens? Or is it exactly the same?
