I PURCHASED THIS FILTER TO PROTECT THE LENS ON MY CANON HF100, AND IT DOES THE JOB WELL.  IT PROTECTS AGAINST DUST AND SCRATCHES, AND ATTACHES WITHOUT ANY DIFFICULTY.  I WILL, HOWEVER, BE PURCHASING A COATED FILTER ONCE I BEGIN USING THE CAMCORDER OUTDOORS THIS SUMMER.  I AM CONSIDERING THE CANON FILTERS FOR ABOUT $60 ON AMAZON.<a data-hook="product-link-linked" class="a-link-normal" href="/Canon-FS-H37U-37MM-Filter-Set-for-Canon-HF10-HF100-DC50-Cameras/dp/B00009V4G7/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Canon FS-H37U 37MM Filter Set for Canon HF10, HF100 & DC50 Cameras</a>
