The NEW ROKINON 8mm Ultra Wide Angle Fisheye Lens is the most affordable 8mm Fisheye Lens in the market. It features the widest field of view over any other 8mm fisheye lens, and its build quality and optical construction are superb. The ROKINON 8mm lens is designed for digital SLR cameras with APS-C image sensors. For these types of cameras, it provides full-frame coverage - which means that pictures will cover the entire frame. It is also compatible with cameras that have a full-frame sensor. For cameras with full-frame sensors, the lens will produce pictures with a semi-circular image and close images will appear proportionately large for a dramatic effect. The ROKINON 8mm lens creates images with an expanded and exaggerated perspective and an extremely wide 180° angle of view. The lens is available for the following mounts: Canon EOS, Nikon, Sony Alpha, Pentax & Olympus 4/3.
5.0 out of 5 stars Waaay better than the peleng, October 22, 2010

This review is from: Rokinon FE8M-C 8mm F3.5 Fisheye Lens for Canon (Black) (Electronics)Well what can I tell you, this lens is awesome, I've testes it and let me tell you some of the results I noticed:
- The amount of flare (even pointing the lens towards the sun) is minimal, it really surprised me in a very positive way.
- It doesn't darkens the corners or produce vignetting effect AT ALL!
- The quality in the final pictures is superb, the pictures are crisp sharp even in the edges!
- Unlinke the peleng lens, the rokinon does fill the entire frame of the picture with no empty corners.
- It does not have the annoying lock ring of the peleng.
- When you handle the lens it feels great, the build quality is great and the rubber grip in the focus ring is awesome, its heaviness makes it feel like a solid rock and well built pice of glass; and, unlike the peleng, it does look modern!
- The colors look nice and saturated in the final pictures.
I loved this one, and I can truely say that this lens will exceed your expectations, the best bang for the buck!

If you are reading the review for this lens, you are looking at a highly underrated lens. The performance of this lens has surprised a lot of critics including Ken Rockwell and photozone. If you are out there shooting with fisheye, you definitely should not mind about manual focus and manual aperture. Otherwise, go ahead and spend 3 times as much of your hard earned money on Sigma or at least 4 times as much on the new Canon 8-16mm L which hasn't been shipped yet. BTW the price of this Samyang fisheye has dropped to $263. Hello? How much does the plasticy Canon kit lens cost? For the quality of its optics and build (metal), the Samyang is a real bargain. The first thing I did with this lens was to shoot toward the sun and confirmed that flares were very well controlled. You get a nice single streak of flares and they are not all over the place. Just be realistic with laws of physics, you cannot expect no flare at all with such wide angle even with nano or whatever coating. This Samyang is arguably the best choice for APC DSLRs with all factors considered. And it 's made in Korea too unlike some N company with cheap Chinese made lenses.
In photography, a fisheye lens is a wide-angle lens that takes in an extremely wide, hemispherical image. Originally developed for use in meteorology to study cloud formation and called "whole-sky lenses", fisheye lenses quickly became popular in general photography for their unique, distorted appearance. They are often used by photographers shooting broad landscapes to suggest the curve of the Earth. Hemispherical photography is used for various scientific purposes to study plant canopy geometry and to calculate near-ground solar radiation.
The focal lengths of fisheye lenses depend on the film format. For the popular 35 mm film format, typical focal lengths of fisheye lenses are between 8 mm and 10 mm for circular images, and 15–16 mm for full-frame images. For digital cameras using smaller electronic imagers such as 1/4" and 1/3" format CCD or CMOS sensors, the focal length of "miniature" fisheye lenses can be as short as 1 to 2mm.
All the ultra-wide angle lenses suffer from some amount of barrel distortion. While this can easily be corrected for moderately wide angles of view, rectilinear ultra-wide angle lenses with angles of view greater than 90 degrees are difficult to design. Fisheye lenses achieve extremely wide angles of view by forgoing a rectilinear image, opting instead for a special mapping (for example: equisolid angle), which gives images a characteristic convex appearance. A panorama by rotating lens or stitching images (cylindrical perspective) is not a fisheye photo.
