different as in you need better quality lens to show of HD resolution.

Anybody found a good fisheye solution yet?

Well if you have the Wide Angle Lens at full wide, and get really, really close to it then you're almost there. Maybe do the rest in post somehow.....

I guess a century optics 58mm will work fine if you have money for it..

I used a very cheap ebay lens attachment and got the results here

Its crap, I dont claim its anything but, thats what fisheyes do though LOL

Here's the lens I bought along with a step down to 43mm

Once again, its a toy and on a HD cam its suspect - not too bad for SD stuff though and perfect for web / youtube.

I'm not sure why you'd pick a 37mm lens, however, I also would like to know if anyone uses Raynox lenses, like HD-6600 (350lines/mm) or HD-7000 (540lines/mm). These lenses have a front filter thread which Canon's WD-H43 doesn't. I wonder if the HD-6600 would be 'good enough' for HD, and whether it won't block the IF sensor. TIA.

Neither was I which is why I asked;-)

I'm curious as to whether you would get seriously heavy vignetting with that or....does the adapter compensate in anyway?

I've got an HD-6600Pro 43mm Raynox coming the end of the week for my HV10. I'll be posting some still shots hopefully by the end of the weekend.

i dont get it.. HV20 is a popular camera, but i called Centruy Optics, and Raynox, and neither of them offer a lens that will fit 43mm threads.. Is anyone going to make something for this cam?

52mm, needed a step up ring.

Well, Raynox does have the 43mm HD-6600Pro... Personally, I decided to use a 52mm step up ring, the filter & lens selection in this size is way better.

I've used a cheap Sony wide angle (VCL-0637 S) with a step down ring to its 37mm threads and I got no vignetting. I haven't checked, but I'm sure the glass on this Sony wide angle is too cheap for HD though.

That would be great John, looks like it should work, it's the same size as the HV20. Post us up a clip once you get some shots with it. I saw a clip using the Wide Angle that Canon makes that someone posted on here and I was impressed, it looked really nice.

Vignetting is not the only problem to watch out for. AFAIK, any lens' resolution is higher near the center. You're losing resolution by using a smaller lens.

I'm anxiously waiting for John Hinkey to test his Raynox HD-6600. If the results are good, I'l get the HD-6600, but in 52mm size which is much more common than 43mm.

My Raynox HD-6600 finally came this week and I threw it on the camera and just looked at the image in the viewfinder.
Unfortunately I bought a silver-colored step up ring and the front of the ring causes a lot of internal light reflections. I'm going to paint/color it black on the inside and post some results perhaps Sat. night. Prelim. first impressions are that it does get a tad bit soft at full zoom, but this was with a wide open aperature in a fairly dark room. The corners looked OK on the LCD in my living room and barrel distortion was not noticeable. Build quality was fairly good (I'm used to the build quality of Nikkor lenses) and does appeart to have single optical coatings looking at the reflections of lights in the front/back elements. I plan to find a brick wall somewhere (local high school should do) and take some stills at various zoom and aperature settings. Hopefully will get something posted (stills only) this weekend.
Stay tuned - John

Thanks for the update. Looks like I made the same mistake by ordering a silvery Cokin step-up ring. Never even thought about it, just went for the thinnest ring I could find. Bummer... I'm not sure if I'll be painting it though, I don't want to have paint dust settle on the optics.

Oooh, many thanks for that bit of insight. Scratching the Cokin off my list.

Argh! The weather here has forced me to put off taking some still images with the Raynox on the HV10. Maybe tomorrow if the rain lets up. I could snap some interior shots, but that wouldn't really be all that interesting now would it.

HV10 + Raynox HD6600Pro:

Well, I took a bunch of 1920x1080 still images of a brick wall at the local high school, but alas I do not have permission to post attachments. How do I get permission to do this?

So, I took stills (super fine/highest quality) over a series of fixed aperatures (F/8.0 to F2.8) with and without the Raynox attached. Unfortunately I bumped up against the 1/500 sec max shutter speed at F/4.0 and F2.8 and bright sun, so the images got brighter with the highlites burned out a bit, but you can still see any softness and some of any CA. The wall was about 10 ft. away, so the focus point was defintely not at infinity. Need a bigger brick wall and a rain-less overcast day.

Anyways, lacking the pictures I can say that at full wide the Raynox exhibits a little bit of softness and CA, but it's not bad and may not be noticeable. This was at the min aperature (F8). At F2.8 it does get a slight bit worse, but not horrible. Full zoom is not recommended. Center is clear, but the edges are really bad. With the Raynox on I zoomed in a little from full wide and the edges were really quite good.

Anyways, when I can have attachments I'll give photos along with commentary and you can see for yourself. Right now I have to say that I may get the Canon WD-H37C since if has full zoom through and maybe a 0.5x for really wide angle only shots (Century Optics single element?).

More to come - John
