Frequently asked questions
What is the difference between a diagonal and circular fisheye?
A diagonal fisheye fills the whole rectangular frame with a 180-degree diagonal view, while a circular fisheye produces a round image.
Does it work on APS-C?
Yes, but the view is narrower and the fisheye effect is less extreme because the sensor crops the image.
Does the Sigma 15mm f/2.8 fisheye have stabilization?
No. Stabilization has to come from the camera body if it offers it; otherwise use a faster shutter speed or a tripod.
