It's the FX. That was careless of me, I should have said. I'll update the title now- thanks for the heads-up.

Hello Phil ! My name is Alex and i am from Moldova republic of... hope you heard of it :)
Listen - I've bought an Samsung VP-HMX20C, i've watched a few of youre videos, liked the ones that are with the fisheye lense atached to the Samsung... so , can you please send me the full specs of the fisheye lense you are using or give me an advice for one... Cause here in Moldova , there are no such products so i am ordering one from Chicago where my friend lives so he can bring one to me .. but i just can't be sure of witch fisheye lense i should order and wich adapter ring i should command with it, knowing that the Samsung is 49 mm .. can you please help me ? thank you !

I wouldn't describe this as a fish-eye. The barrel distortion is too mild- at least when fitted to the Samsung. The specs- I'm not sure what I have left out from my review that you'd want to know- could you be more specific?

As for the step-up ring, again, can't think what to say that isn't in the video. There's really only two numbers you need- camera-side diameter and filter-side diameter. Samsung is 49mm, and this particular model of wide angle adaptor is 72mm. Some step-up rings are thicker than others, when using a wide-angle adaptor, you generally want as thin as you can get, and this one is great in that respect, as it does the conversion in one step. If you can't find a single ring to do it like I did, you might have to use two, which increases your chance of vignetting.

One fact missing from the video- it weighs 60.2g (2.125oz) on its own, and 98.8g (3.485oz) with the step-up ring (made of decent grade brass).
