Specs: Fisheye vs Autofocus Prime
Lens type and perspective
The 7artisans 7.5mm f/2.8 Mark II is a dedicated fisheye lens. It offers a 190-degree viewing angle with a 9-group, 11-element optical structure. This creates extreme distortion for artistic effect. In contrast, the 7artisans AF 25mm f/1.8 is a standard prime lens. It provides a natural wide-angle perspective without the curved lines of a fisheye. You choose between extreme creative distortion or a conventional, usable field of view depending on your subject matter.
Autofocus capability
The 7artisans AF 25mm f/1.8 features STM autofocus with eye detection. It uses a high-torque stepping motor for fast, silent, and precise focusing on human eyes. This is ideal for portraits and video. The 7artisans 7.5mm f/2.8 Mark II is a manual focus lens only. You must adjust focus by hand. If you need automatic tracking for moving subjects or quick shooting, the AF 25mm is the clear functional choice for modern workflows.
Maximum aperture
The 7artisans AF 25mm f/1.8 has a bright f/1.8 maximum aperture. This allows significantly more light intake, enabling better low-light performance and shallower depth of field for creamy bokeh. The 7artisans 7.5mm f/2.8 Mark II tops out at f/2.8. While still relatively wide, it gathers less light than the f/1.8 option. The smaller aperture results in a deeper depth of field, keeping more of the scene in focus.

The data does not list mounts for other systems in this specific comparison.
Physical dimensions and weight
The 7artisans 7.5mm f/2.8 Mark II weighs 1.26 pounds and measures 2.49 inches in height. It is a heavier, bulkier unit due to its fisheye construction. The 7artisans AF 25mm f/1.8 is ultra-lightweight at approximately 183 grams. It measures 2.2 inches in height and 2.5 inches in length. The AF lens is significantly easier to carry for everyday use.
