Tokina’s AT-X 107 AF DX Fisheye Zoom; It Keeps The Look Throughout The Zoom Range Page 2

One thing you need to be clear about: this zoom maintains its fisheye characteristics even when zoomed out to 17mm. Barrel distortion, while not as pronounced as at 10mm, is still fairly apparent and all the provisos noted earlier apply. That said, it is easier to correct distortion at 17mm in post, since the effect is less flagrant. So when I approached a beautiful, white stone church in my neighborhood, I was fully prepared to deal with lens distortion. I recalled a shot I took of a church interior with my first fisheye in Old San Juan, Puerto Rico, and couldn't wait to get inside. I waited for services to end, and with the priest's permission proceeded to photograph the interior from virtually every angle. I made exposures at the various zoom settings, but focused mostly on fisheye views. One shot of the church organ on an upper level was especially impressive, as was a wall replete with stained-glass windows. I of course photographed the church exterior as well.

Shooting with the Tokina fisheye at the 10mm setting, you get a completely different perspective when shooting with the camera held level and aimed straight into the scene, compared with shooting at an angle, which exaggerates distortion effects. Owing to low-light levels, all church interiors were shot at ISO 3200.

As far as sharpness and contrast in the AT-X 107 AF DX Fisheye zoom are concerned, I had no complaints. Clearly and expectantly, the lens is sharpest at its center, with the image growing softer toward the edges, notably when delivering full fisheye coverage. Still, overall optical performance was impressive. I was hard-pressed to see a difference in a nearly identical image of the same scene shot with a fixed fisheye and with this zoom.

All I know is that I liked this lens so much I'm buying it. I anticipate making good use of the fisheye zoom to give me a whole new perspective on the world.

Optical performance clearly drops off toward the left and right edges when the AT-X 107 AF DX Fisheye was shot at 10mm for this fisheye perspective. However, examine the cropped central section and note how clear the text is.
