Polar 8mm f/3.5 FishEye CS

Different and fun This (Rokinon 8mm) fish-eye lens is way different than any "normal" lens you've used. Its really wide angle of view allows you to capture everything in front of you. You can get creative by moving up close, down low or up high to obtain unusual photos. It's a fun lens. The photos I took are extremely sharp. Although it's a manual focus, using the distance dial indicator on the lens is easy. It is also very forgiving - and setting it at infinity gets everything farther than 5 feet in focus. The model I bought had the Aperture chip which provides exposure feed-back to the camera allowing for quick and accurate exposure on my camera (Nikon D5300). This is a great a lens for the money.

Rokinon 8mm Fisheye F3.5 Manual Focus A fisheye is a toy. This is a manual focus lens and I don't think that there is any real way to focus an 8mm fish eye via a viewfinder. You have to pretty much set focal distance and then shoot. Inifinity for this lens starts above 10 feet so that isn't a big deal for most photos and inside 10 feet there is a pretty good margin of error. The lens will let you focus between marked focal lengths but there are no "notches" in the ring so you will have to do it by looking at the ring or physical memory. Without losing track of the fact that it is a toy, I love it and would buy it again. The uses of this lens are limited and depend entirely on your creativity. The cap could be better but it stay put when in place. My only real complaint is that the lens mount on mine is tight, very tight. It actually scared me the first time I used it but I'm hoping it will loosen up over time. Optically, it is good and if you have a good light source (minimum aperature 3.5), you can do some really nice things with it stopped down from 5.6 to 8. To the extent that it is not autofocus, since you can't confirm focus through the view finder, I think autofocus could be problem because you'll never be certain whether the camera is doing what you want. Manual focus may actually be a blessing inside 10 feet. For the price, it is good glass. I bought mine because Ken Rockwell recommended it on his website. My comments are similar to his but you should read his review because -- he has a website and you know who he is. You don't know me from Adam.Read full review

Fun Fisheye to Use! This is the third Rokinon lens I've purchased, and it is built well. The 8mm AE Nikon lens performs well and takes great shots, just need to watch out so I don't photograph my feet! A good lens to hone my manual photography skills. Works OK for astrophotography for capturing full starry skies.
