7artisans 10mm f/3.5 APS-C VS AstrHori 6.5mm f/2.0 APS-C Fisheye

The 7artisans 10mm f/3.5 APS-C and the AstrHori 6.5mm f/2.0 APS-C Fisheye are both prime lenses, but they differ in a few key areas. The 7artisans lens features a Micro Four Thirds mount, while the AstrHori lens has a Canon RF mount, meaning they are designed for different camera systems. Additionally, the 7artisans lens does not offer weather sealing, whereas the AstrHori lens is weather-sealed (splashproof), providing more durability for outdoor shooting conditions.

In terms of build, both lenses have a metal mount, ensuring sturdy connections to the camera body. However, the 7artisans lens is lighter at 125.5 g compared to the 268 g of the AstrHori lens, making it more portable. The 7artisans lens also lacks a lens hood, while the AstrHori lens includes one, which can help protect the lens and reduce flare. The filter size of the 7artisans lens is 37 mm, which is smaller than the 64 mm filter size of the AstrHori lens.

Overall, while both lenses offer solid build quality with metal mounts, the AstrHori lens is heavier, includes a lens hood, and is weather-sealed, while the 7artisans lens is lighter and has a smaller filter size.

The 7artisans 10mm f/3.5 APS-C and the AstrHori 6.5mm f/2.0 APS-C Fisheye have similar features in terms of focal length and image stabilization. Both lenses have a fixed focal length: the 7artisans at 10 mm and the AstrHori at 6.5 mm. Neither lens has built-in optical image stabilization, so users would need to rely on their camera body for stabilization if required.

Regarding the angle of view, the 7artisans lens offers a maximum and minimum angle of view of 108°, while the AstrHori lens provides a much wider 192° for both its maximum and minimum angles of view, reflecting its fisheye design. This results in a significantly broader field of view with the AstrHori lens, making it more suitable for dramatic wide-angle shots.

Both lenses have an optical zoom of 1x, meaning neither offers zoom capabilities, further reinforcing their fixed focal length nature.

The 7artisans 10mm f/3.5 APS-C and the AstrHori 6.5mm f/2.0 APS-C Fisheye differ in aperture values. The 7artisans lens has a wide aperture of f/3.5 at both its main camera and maximum focal length, whereas the AstrHori lens has a larger wide aperture of f/2.0 at both its main camera and maximum focal length. This results in the AstrHori lens allowing more light to pass through, which can be beneficial for low-light shooting.

Both lenses have the same smallest aperture of f/22 at the minimum focal length, so they offer similar depth of field control at that setting. However, the number of aperture blades differs: the 7artisans lens features 5 aperture blades, while the AstrHori lens has 9 aperture blades. This can impact the appearance of out-of-focus areas, with the AstrHori lens potentially providing a more pleasing bokeh effect.

In summary, the AstrHori lens has a wider aperture range and more aperture blades compared to the 7artisans lens, which could influence image quality and bokeh characteristics.

Both the 7artisans 10mm f/3.5 APS-C and the AstrHori 6.5mm f/2.0 APS-C Fisheye can focus to infinity, making them suitable for wide-angle shots where distant subjects are in focus. Both lenses also offer full-time manual focus, allowing users to adjust focus manually at any time, even in autofocus mode. However, there is a difference in focus motors: the 7artisans lens does not have a silent focus motor, while the AstrHori lens includes one, which can make it more suitable for video work where quiet focusing is important.

Both lenses have the same minimum focus distance of 0.2 m, so they are equally capable of capturing subjects at very close range.

In summary, while both lenses have similar focus capabilities in terms of distance and manual focus, the AstrHori lens has the added benefit of a silent focus motor, which the 7artisans lens lacks.
