Manufacturer description
The 7.5mm F3.5 ultra-wide angle fisheye lens has a 205° ultra-wide shooting angle, and the pictures are more impactful and spatial, making your works more amazing. The lens uses nano-coating technology to effectively prevent flare and ghosting. The closest focusing distance is only 0.29m, which can effectively enhance the impact of the image. The use of robust all-metal materials ensures that daily knocks and use in harsh environments will not damage the optical elements inside the lens. The petal-shaped integrated lens hood prevents stray light from entering the lens and reduces reflections, prevents bumps and effectively protects the lens.
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 (*).
(*) Some APS-C models have a detachable lens hood, which allows such lenses to be used on 35mm full-frame cameras as circular fisheyes.
From the editor
At 657g, this fisheye lens is on the heavy side. We doubt any amateur photographer would want to use it for long periods of time during a shooting day.
