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.
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. B) The image is distorted to the point near fish-eye. C) Image will be blurred when you try to zoom in. I can't believe Sony sells this item.
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. I have a couple of Sony and Canon wide angles that cost anywhere from $100-$180.
Summary: I already own the VCL-0637H lens which is about twice as deep and is also about twice as heavy. I found this lens on clearance at a Walmart for $21 so I thought I would give it a shot. It was SO much lighter and looked much nicer because it didn't protrude from the camcorder as much. The carrying case for it is really cute too. I was so happy until I tried to zoom.
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. It is a shame because the seller wouldn't take it back since the package has to be "broken" to take the lense out, so I'm stock with it for good. Even Sony Style has it advertised as compatible to my camcorder, WHAT'S UP WITH THAT!
Summary: I've had this gear for almost a year or more, using it quite often with daily use over weeks straight, and it's getting a 3' rating because the lens quality isn't up to snuff. I'd love to give it 4''s since it's terrific... I mean, terrific... to quick-snap the lens on or off, instead of having to unscrew it, like most of the lens adapters out here.
