Manufacturer description
This digitally optimized diagonal fisheye lens is equipped with a new multi-layer coating technology that reduces both flare and ghosting. By taking advantage of both the distortion aberration, specific to fisheye lenses and the minimum shooting distance of 15 cm (5.9 in.), the photographer can shoot creative images.
The 180 degree field of view of this fisheye lens can be used to create amazing image expressions that cannot be seen with the human eye, such as exaggerated perspective and distortion.
The minimum shooting distance of this lens is only 15cm (5.9 in.) and it has maximum magnification of 1:3.8.
This lens is supplied with a gelatin filter holder at the rear, allowing the use of gelatin filters.
Typical characteristics of fisheye lenses
- Extreme angle of view (at least 180° diagonally);
- Circular types (the image circle of the lens is inscribed in the image frame) or diagonal types (cover the entire image frame);
- Usually of equidistant projection type, with the distance from the picture center to any given point always proportional to the angle from the optical axis to that point;
- Huge barrel distortion;
- Short closest focusing distance (0.20 - 0.30m with 35mm full-frame prime lenses);
- Very large depth of field, eliminating the need for autofocus or precise manual focusing;
- Due to the extreme angle of view and convex front element, front filters cannot be used;
- Often equipped with a filter turret with swivel-mounted filters;
- Often come with a small, built-in petal-shaped lens hood.
Notes
- The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3500, D5000-D5600 digital SLR cameras.
