Summary: I bought this lense for a DCR-HC28 MiniDV Handycam® Camcorder, it does bring the adaptor for the camcorder, but the lense is so wide that it covers the focus sensor so it is impossible to use it this way.
Summary: Bought it for C$69.99 (Canadian), went for vacation and regretted not have returned in time. 3 issues with this lens compared to my other cheap conversion wide lens. A) The adaptor that screws into the camcorder is made of plastic, hence durability is not good.
Summary: Purchased this converter as I wanted something more compact than other wide angle converters. If you want the fisheye look, then get this lens, otherwise it's unusable for regular shots as it distorts perspective too much. I have always put a wide angle converter on my miniDV and HD cams.
Summary: Browsing around Walmart, I found this lens for $20 so I snagged one for my older Sony TRV-240 (Digital8 camcorder) All in all, it's a nice lens. I was hoping to maybe go a tiny bit wider, but anything much more than .7x would cause very noticeable barrel distortions.
Summary: It is very inexpensive, so I wouldnt discourage buying it, but I assumed that it came with the 3 other rings for adapting it to the camera I purchased it for. It did not. Duct tape, and its all good.
