Opteka 6.5mm f/3.5 Manual Focus Aspherical Fisheye Lens for Pentax and Samsung Digital SLR Cameras Reviews

I own the Bower, not the Opteka, but from the picture, they look identical - only the Vivitar is different in the exterior finish. All these lenses appear to be made by Samyang, a South Korean company that puts out several mirror and normal tele-lenses, and that more recently came out with two higher quality prime lenses - this 8mm f/3.5 and an 85mm f/1.4 ( Opteka 85mm f/1.4 Medium Telephoto Portrait Lens for Pentax K7, K200D, K20D, and K2000 Digital SLR Cameras) First, a note on the lens pictured here: the amazon photo probably...

When it came to my house, I placed it on my Pentax K10d and took some foliage shots on my street. The angle of acceptance isn't exactly 180 degrees, but it makes a full frame photo on my 1.5 Pentax sensor. I took some photos of my house through a maple tree, and both the leaves that were only 24 inches away, as well as the house 70 feet away were needle sharp! Now mind you...This lens is totally manual in focus and aperture operation, with automatic stop-down aperture when the shutter is tripped. When Opteka said Aspheric, I was a bit suspicious, but when I took the photos of the Rock group, the true meaning of aspheric came through with shining colors! I layed the camera on the ground facing up, with the self timer...

Easy to focus, tends to shoot a bit underexposed. However, due to Amazon's ludicrous handling of gift cards, I could not get the extra item (digital picture frame) because it wanted to use a gift certificate I'd been holding for my kids to pay for the frame via a credit and then use the credit to "pay" for the frame. Shipping was quick from 47th st. Kudos to them, but Amazon isn't helping the merchant out with this screwball ordering process and it costs the product a star. |

Product Description
The Opteka 6.5mm f/3.5 Fisheye Lens is an excellent addition to any photographer's collection, giving users the ability to expand their creativity and capture incredible scenes from a truly unique perspective. The special fisheye design allows maximum creative expression. This lens, when used with cameras with an APS-C image sensor, creates images with an expanded perspective, including images with a creatively deformed outlook and a sharp pan focus that extends throughout the entire frame. By offering a 180-degree angle of view, this fisheye lens can be used to create amazing image expressions that cannot be seen by the human eye, such as exaggerated perspective and distortion. The minimum shooting distance (just 12 inches) and large depth of field also provide amazing close-up shots. Opteka's super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.

- Actualizes a 6.5mm focal length and a diagonal angle of view of 180 degrees for APS-C size
- Corrects aberrations using a complex aspherical lens. When fully opened
- Petal type hood and super multi-layer coating help control flaring and ghosting
