[HDRI] RE: camera + fisheye

[Timo Kunkel]

Hi Magali!

The SIGMA 8mm fisheye will work on a more reasonably priced camera with a
cropped sensor (usually about factor 1.6 or 1.3), but you won't capture the
full circle of 180deg.
However, I read a while ago that SIGMA is planning to release a full 180deg
fisheye for cropped sensors (like those used in the entry and semi-pro SLR
lines). 
Here are the links:

These can then be combined with the more affordable Canon or Nikon SLR
bodies.

A benefit of a 36x24 sensor (full frame) might be the better low light
sensitivity due to larger photosites (pixels). It might be therefore worth
to give the camera systems of choice a try if possible if they fit your
need.

Cheers,
Timo
