Sigma Announces Two New Digital Fisheye Lenses
Today lens manufacturer Sigma announced two new fisheye lenses made specifically for cropped sensor digital cameras (such as the 1.5x cropped Nikons and 1.6x cropped Canons). The first lens is a 10mm fisheye, yielding an approximate field of 180 degrees across the diagonal (only ~170 degrees on the Canon). This lens focuses down to a staggering 1.8cm from the lens glass - so underwater photographers will need to be careful not get get lint or bugs in their dome ports - lest the lens refuses to focus past the dirt :-)
The second is a 4.5mm circular fisheye lens which yields a complete 180 degree circular field of view. These lenses will be available in Nikon, Canon, and Sigma mounts, however, pricing and availability haven’t been announced yet.
