KA. It has automatic aperture. Can be used manually, also (has an aperture ring).

question

On APS-C sensors, is this a rectilinear or circular fisheye?
Asked by: Hung N.
As per the Overview (description) this fisheye lens produces rectangular photos on an APS-C camera, such as the Pentax K-5 II. Objects with straight lines will appear curved toward the outer edges of the image. The description also says that this lens will produce a circular image when used on a Pentax dSLR with a full frame sensor.

question

is this is rectilinear or circular fisheye?
Asked by: Hung N.
The lens is close to stereographic projection, a mild form of fisheye that does not compress the edges as much as traditional fisheyes. Unlike fisheye or rectlinear distortion, stereographic design yields circular spheres more perfectly round. It is the preferable projection for shooting groups of people.

question

This will give me vignette using a canon t3i correct?
Asked by: Anonymous
No. When using a crop-sensor camera like the T3i, you will see a full rectangular image, with an approximate equivalent focal length of 12mm (1.5x crop factor multiplied by 8mm). You will see a vignetted circular image when using this lens on a full-frame sensor.
