Fish Eye Lens, I need your help!!

[Bakko]

Hello photo forum peoples.
I've been torn between these 2 fish eye lenses:
Amazon.com: Rokinon FE8M-N 8mm F3.5 Fisheye Lens for Nikon (Black): Camera & Photo

and

Amazon.com: Vivitar - Fisheye lens - 7 mm - f/3.5 - Canon EF: Camera & Photo

I searched for reviews for these two lenses but I couldn't really find much.
Anyone have any experience or know anything about these 2 to help make a decision?

Thanks!

Me thinks they're they same lens, only a different label.

The price is roughly the same. The vivitar is slightly more expensive, but i cant really tell the difference between the 2

Like 480sparky says, they are the same lens, just branded differently. There are some slight cosmetic differences for each brand, but all the internal stuff is identical.

The lens is made by Samyang. http://samyang.pl/product,96,category,5,samyang_8_mm_f35_aspherical_if_mc_fisheye
