Summary: conceding that i like the aberrations and vignetting that it produces this is the best of 3 different cheap fisheye adaptors that i owe main qualities is amazingly small and fits pretty well with my kit lens. sincerely i never take it out of it. quality is good. it survived numerous falls including one that broke the lens itself a little bit (although i got a little crack in the black coat what lets light pass thru creating some flares but was my fault cause i oppened it...
Summary: Using this with a Lumix LX7. When I first put this lens on, I thought my prime lens was rubbing against the metal of the fisheye lens. I carefully disassembled the lens and discovered that it does not touch, and only the adapter lacks sufficient depth for both to fully thread. This does not effect the performance or tightness of the fisheye to camera, as long as you partially thread all parts together, then tighten.
Summary: This lens would have worked great if it fit my grandson's Vivitar camcorder, but the camcorder has a little built-in light on the original lens. Therefore we cannot screw on this fish-eye lens. He was very disappointed. There should be a warning about this. We didn't return it as we thought we might buy another camera without a built-in light, but we haven't done it yet. The lens package arrived in a short time.
Summary: The first time I put this on my camera, I was literally disgusted. It was a huge waste. However, after letting it sit around for a few months I was playing around with it and figured out that if you unscrew the top and remove every lens except for the top one, it goes from being a horrible fisheye to being a pretty decent wide angle lens with no vignetting. I would suggest this lens only if you plan on doing this. Otherwise it's a waste of money.
Summary: I thought this was a pretty good fisheye adapter lens. I used it with my Canon S90 and my friends love the shots. Check out the pics I uploaded on this page. Don't expect to the edges of the fisheye to be very sharp since this is a $30 odd fisheye add-on lens- you need to pay $600 odd to see sharp corners for fisheye lenses.
Summary: i really dislike this fish-eye. barely has the fish-eye effect...when you zoom in half way the edge blurriness goes out of control. found this vid on youtube about this lens [...] so go and check it out.
Summary: This is not a fisheye, really. I mean, it's a very wide angle, but it's not that spherical. Plus, the edges are pretty fuzzy. I really doubt that it's 0.21x! I have a 0.45x that is almost as wide! Now don't get me wrong...this is a really cool lens for a certain EFFECT, and it's surely cheap, but other than that, it's not really a true Fisheye...there are a lot better out there.
Summary: This fisheye is horrid. Too much vid on every cam i put it on. not 180 degree angle. But i modded it. i took off the lenses then unscrewed the macro. removed the macro and then put the lenses back and the fisheye acts now like if it were a opteka baby death. I got so relieved i bought this fisheye. it made my day when i modded it 5 minutes ago. I would recommend this fisheye only if you mod it how i did. SO WORTH 36 bucks.
