Rokinon 8mm f/3.5 overview

  • 1Description

The 8mm f/3.5 Fisheye Lens with Removable Hood for Pentax K from Rokinon gives you a 180º view with dramatic, exaggerated perspective when used with an APS-C camera, or a powerful circular image floating in the frame when used with a full frame digital camera or 35mm film camera. With hybrid aspherical elements and multi-layer coating, you will produce sharply defined images with a minimum of flare and ghosting. The 8mm lens focuses as close as 12" (30.48cm) from the lens. This version of the 8mm f/3.8 Fisheye lens comes with a removable lens hood that will offer glare reduction and lens protection, but can be removed to offer an increased and unobstructed angle of view when shooting with full frame digital or 35mm cameras. 

Note: Produces a circular, vignette image on full-frame sensors or 35mm film

    Rokinon 8mm f/3.5 reviews

    8mm f/3.5 HD Fisheye Lens with Removable Hood for Pentax K is rated 4.0 out of 5 by 5.
    Rated 4 out of 5 by from Fun with Fisheye Good value, provides a creative alternative that can make for some really nice scenes (see my uploaded example photos taken with Pentax K-5 II), includes squeeze-to-release lens cap that secures nicely to grooves in top & bottom petals of lens hood plus a good faux leather drawstring pouch. Instructions seem a bit terse (and cover multiple versions for other cameras such as Nikon, et al) but do provide enough specific Pentax info to make it work correctly set aperture ring to red A-dot indicator just to left of F/22 by holding small chrome plated button depressed while turning ring; set mode dial to Av - Aperture priority and set focusing lever to MF - Manual focus... input 8mm focal length when prompted by the camera. Focusing ring has nice ribbing and is easy to use, but for most shots this lens will be set to Infinity (focusing can be used for subject distances of about 5 feet or less).

    Rated 4 out of 5 by from Wide. Really wide. I bought this for use at a wedding but also because I thought a real fisheye would be cool. You can't beat the kind of distortion a lens like this produces, and I expect to have a lot of fun with it. Because of the very short focal length, I almost don't need to focus it, which is good because it does not autofocus. One thing to remember when you put it on the camera is to set the camera to manual focus. Otherwise, the camera may refuse from time to time to release the shutter.

    Rated 4 out of 5 by from 8mm f/3.5 HD Fisheye Lens with Removable Im happy with the fact that the aperture is set automatically in all camera modes, , I set the focus for 2 feet and all is well. If I change to a future Pentax with a full frame, it will still work as a circular fisheye, by detaching the lens hood. Forward compatible if you will. Photographs are great as well. You must set the mmon the camera for the shake reduction to work well. ;this is easy as the camera K5 prompts you every time you out this lens on

    Rated 4 out of 5 by from great for the price This works very well and produces good results. the pictures are a little soft at wide open F3.5 but the results overall are close to the name brand 1000 dollar equivalent.

    Rated 4 out of 5 by from Good and cheap lens to have The distortion isn't too much and is acceptable.
