Test: Einzeltest: Sigma 8mm f/3.5 EX DG Circular Fisheye review
Zitat: For those needing this type of lens, for example when using software to create panoramics or for those involved in the scientific measurement of angles, where the output from this lens is quantifiable, this lens is an excellent tool. For those who just want to experiment with the unusual perspective of a 180° field of view, or even the somewhat reduced field if using the lens on a cropped sensor, then this lens is a high class example. In summary, the positive points of the Sigma 8mm f/3.5 EX DG Circular Fisheye are: High optical resolution Good control of aberrations Compact size and weight The negative points are: Restricted uses (but it is a specialised lens) Expensive if only being used for the fun element
