... mounted on a Samsung SC-HMX20C/XAA mini HD camcorder. I tested three different Tele Adapters and this was the only one that was Good. One MUST use a conversion lens that is specifically for DIGITAL cameras ... otherwise one will get poor resolution and a lot of odd artifacts and aberrations. I bought this Cokin 2X Telephoto Conversion lens through B&H Photo Video. BUT, the one I received and tested had a LOT of dust on the back side of the front element. It seemed completely sealed, so there was no way I could clean it out. I am returning it to B&H. They were very good about that and even supplied a UPS pre-paid shipping label. NOTE that like most of these type of tele adapters, one can NOT zoom all the way out without seeing some vignetting.
