A Very Fun Lens,
Great For Extreme Distortions
Since the 1970's, I've owned an FX
fisheye, starting with the Sigma 8mm , and then to a Nikkor 16mm auto focus fisheye. So, when Tokina announced this lens (is really identical to the Pentax, in the identical focal length), I just had to get one to fit my Nikon D90.
The zoom is a nice feature since the amount of the effect of the fisheye may be changed by backing off somewhat from it's
focal 10mm length. Although it will not
auto-focus entry level Nikons, there's not a lot of need for exact focus using this lens because of it's extreme
field depth at these short focal lengths. Surprisingly, when it's mounted on an F100 film body, naturally
vignetting occurs, acquiring the lens hood within the image, although zoom it out some and the vignetting goes away. So, with a little cropping, this lens could be used on a full frame
film camera and produce some interesting photos.
Sharpness seems good, although. I am not a lab rat and I do not buy my lenses just to photograph brick walls or any other subject that must be absolutely razor sharp from edge to edge. If you would just like a creative, fun, lens that ensures that your pictures will always contain a unique interpretation from your friends who acquire the shot fron an identical position, this just might be your lens!
A fisheye lens captures a wide, hemispherical image on the extreme side. Initially developed for meteorology use in studying formations of clouds and labeled as "whole-sky lenses", these fisheye lenses fast became popular for all around photography because of the unique, distorted appearance of photographs they captured . They are typically used by photographers acquiring broad landscapes that suggest the earth's curve.
Hemispherical photography is also used for an array scientific purposes in studying the geometry of plant canopy and for calculating solar radiation near the ground.
The first fisheye lenses which were created were "circular fisheyes" type lenses which capture a 180° hemisphere which shows as being a circle within a film or sensor frame. A few circular fisheyes can be acquired in orthographic projection versions for scientific applications. These lenses feature a 180° vertical viewing angle, while the diagonal and horizontal viewing angle are also 180°. The typical circular fisheye lens covers a lesser image circle as compared to rectilinear lenses, allowing the frame corners to be completely dark.
The new Tokina AT-X 107 DX is a
fish-eye lens that
is optimized for
digital SLR cameras and gives the
photographer a 180&Mac176; field of view with dramatic curvature of field or “fish-eye” effect. With this lens an entire
view or vista
can be captured, wider than the human eye can see. The AT-X 107 opens an entirely new dimension of
The front element of the AT-X 107 DX
lens has a newly formulated WR or “Water Repellent" optical coating on the glass. This new coating makes marks such as spots left by water or finger-prints much easier to clean than standard
The rear optical group of the lens contains 1 SD (Super-Low Dispersion) glass element to reduce the number of elements (pieces of glass) in the optical design in order to make the lens more compact, light-weight and faster focusing.
