Independent lens maker Sigma has released an 8mm f/3.5 EX DG circular fisheye lens, priced around £600.
The ?digitally optimised? lens boasts an 180° angle of view on 35mm film SLRs and full-frame digital SLRs, according to Sigma.
Features include a minimum focusing distance of 13.5cm and maximum magnification of 1:4.6.
The optic includes a multi-layer coating intended to reduce flare and ghosting.
?This lens is ideal for photographers using computer stitching software which requires circular fisheye images to be input, resulting in stitched panoramas,? said a spokesman for the company.
The lens comes with a padded case and a holder for gelatin filters.
