Read All Reviews for Rokinon 8mm F3.5 Ultra Wide Aspherical Fisheye Lens for Pentax

Great lens for the price and I recommend it if you like fisheye photos!

Smaller than most fish-eye lenses. I wish it were a little faster, but you can't beat the price. It's sometimes difficult to tell that the image is out of focus through the viewfinder until you check the image. It may that I've gotten lazy using AF, and it's just something to get used to. Overall, it does exactly what it's supposed to - takes wacky looking skewed photos.

This lens (identical to Samyang, Vivitar, Polar, Bower, Falcon versions) lives up to the rave reviews. Cheap, good built quality (all metal except the lens hood, front cap seems cheap though), well damp, surprisingly good optic. My experience with Great Offer Stock is excellent. Free shipping took 5 days to Canada, not bad at all. Good, well padded package. Definitely would buy here again. Highly recommend.
