Zoom vs Fisheye Lens Comparison
Lens Type and Function
The Canon RF 75-300mm is a telephoto zoom lens, designed to extend your reach for distant subjects. It offers a versatile focal length range that allows you to get closer to wildlife, sports, or portraits without compromising portability. In contrast, the 7artisans 7.5mm is a fixed focal length fisheye lens. It provides an ultra-wide shooting perspective with a 190-degree viewing angle. This creates significant artistic distortion and visual impact, ideal for creative scenes, VR panoramas, or underwater photography. You choose the zoom for versatility and distance, while the fisheye delivers extreme wide-angle distortion for specific creative effects.
Sensor Format Compatibility
Sensor compatibility is a major differentiator between these two lenses. The Canon RF 75-300mm is designed for both full-frame and APS-C Canon mirrorless cameras. This dual compatibility gives you flexibility if you switch bodies within the Canon RF ecosystem. The 7artisans 7.5mm fisheye is explicitly listed as an APS-C lens for Nikon Z cameras. While the data notes it is for APS-C, the primary mount listed is Nikon Z. You must ensure your camera body matches the specific mount and sensor format requirements. The Canon lens offers broader sensor format support across its zoom range, whereas the 7artisans is strictly limited to APS-C sensors.
Aperture and Light Gathering
Aperture specifications vary significantly between these options. The Canon RF 75-300mm features a variable maximum aperture of f/4-5.6. This means the lens opens up to f/4 at 75mm and narrows to f/5.6 at 300mm. This variable range helps keep the lens profile slimmer and lighter. The 7artisans 7.5mm offers a constant maximum aperture of f/2.8. A wider f/2.8 aperture allows more light to enter the sensor compared to f/4-5.6. This helps shorten exposure times and improves performance in lower light conditions. If you need to shoot in dim environments or want more control over depth of field, the fisheye lens provides a distinct advantage with its brighter constant aperture.
Autofocus and Control
The method of focusing differs between the two lenses. The Canon RF 75-300mm utilizes a DC autofocus motor. This ensures smooth and precise focusing, which is essential for tracking moving subjects like sports or wildlife. It also features a minimum focus distance of 4.9 feet with 0.25x magnification. The 7artisans 7.5mm fisheye is a manual focus lens. It lacks an autofocus motor, requiring you to adjust focus by hand. This manual operation suits static scenes, landscapes, or creative work where precise control is preferred. If you need automatic tracking for action, the Canon lens is superior. For deliberate, manual control, the 7artisans offers a traditional shooting experience.
Bundle and Included Items
The package contents differ substantially. The Canon RF 75-300mm is sold as a bundle that includes the lens, a 58mm 3-piece filter kit, a large camera lens bag, a lens cap keeper, and a cleaning kit. This comprehensive package provides immediate accessories for protection and maintenance. The 7artisans 7.5mm is listed as a standalone lens with no mention of included filters or bags in the provided data. You receive just the lens itself. The Canon bundle offers more immediate value and convenience for setup, while the 7artisans requires you to purchase accessories separately. This makes the Canon option more complete out of the box for new users.
Which Mirrorless Lens Fits Your Needs
You want reach for distant subjects
The Canon RF 75-300mm offers a 75-300mm focal length range, allowing you to zoom in on wildlife or sports. Its DC autofocus motor provides smooth focusing, while the 4.9 feet minimum focus distance lets you get closer to subjects. This telephoto zoom is ideal for extending your range without compromising portability.
You need ultra-wide creative shots
The 7artisans 7.5mm fisheye delivers a massive 190-degree viewing angle, perfect for scenery or VR panoramas. Its f/2.8 large aperture helps shorten exposure times, keeping stars or auroras bright. This manual lens creates strong visual impact with its ultra-wide perspective, enhancing artistic effects in your wide-angle photography projects.
You prioritize lightweight travel gear
The 7artisans 7.5mm fisheye weighs only 1.26 pounds and measures 2.4 inches in length. This compact build makes it an excellent travel companion compared to bulkier options. Its small size fits easily into bags, allowing you to carry it without adding significant weight to your camera setup during long shoots.

Frequently asked questions
Can I use a fisheye lens on any mirrorless camera?
You must match the lens mount to your camera body. The 7artisans 7.5mm fisheye listed here is designed specifically for Nikon Z mount cameras. It supports APS-C sensors. You cannot attach it to a Canon RF mount camera without an adapter, and even then, functionality may be limited. Always check the mount compatibility before purchasing.
What is the main difference between a zoom and a fisheye lens?
A zoom lens changes focal length to frame subjects closer or further away. The Canon RF 75-300mm offers a versatile range for distant subjects. A fisheye lens provides a fixed, ultra-wide angle with intentional distortion. The 7artisans 7.5mm delivers extreme wide-angle coverage for creative effects. One tool extends reach, while the other expands perspective.
Is a telephoto zoom better for wildlife photography than a fisheye?
Yes, if you need to capture distant subjects. The Canon RF 75-300mm is ideal for wildlife because its 75-300mm range allows you to get closer to animals without disturbing them. A fisheye lens like the 7artisans 7.5mm captures a wide scene but cannot magnify distant details. Choose the zoom for reach and the fisheye for creative landscapes.
How heavy are these mirrorless lenses?
Weight affects portability during long shoots. The Canon RF 75-300mm telephoto zoom bundle weighs 2.32 pounds. The 7artisans 7.5mm fisheye is lighter at 1.26 pounds. The fisheye is more compact, measuring 2.4 inches in length. The zoom is longer at 5.75 inches. Consider your camera bag space and carrying comfort when deciding.
Does the fisheye lens have autofocus?
The provided data for the 7artisans 7.5mm fisheye does not specify an autofocus motor. It is a manual focus lens, which requires you to adjust focus by rotating the ring. In contrast, the Canon RF 75-300mm uses a DC autofocus motor for smooth focusing. If you prefer automatic focusing, the zoom lens is the suitable option here.
Can I use the Canon zoom on Nikon cameras?
No, you cannot use it directly. The Canon RF 75-300mm uses Canon RF Mount, which is exclusive to Canon mirrorless cameras. The 7artisans 7.5mm uses Nikon Z Mount for Nikon Z cameras. You must buy the lens that matches your specific camera brand and mount system. Cross-brand compatibility is not supported for these specific models.
