Overview of the Products
The 7Artisans 4mm F2.8 Fisheye Ultra Wide Angle Lens is priced at $149.00, making it significantly more affordable than the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens, which costs $569.00. This price difference of $420 means the 7Artisans lens is approximately 74% cheaper, appealing to those who prioritize budget-friendly options in photography.
The 7Artisans lens is designed for Sony E-mount APS-C mirrorless cameras, while the Canon lens is specifically tailored for APS-C cameras with a versatile zoom range of 18-150mm. Each lens serves distinct photographic needs, from ultra-wide perspectives to standard telephoto capabilities.
Design and Build Quality
The 7Artisans lens boasts a compact design with a weight of only 201g, making it portable and easy to handle during travels. It measures approximately 60mm in diameter and 54mm in height, allowing for comfortable one-handed use. In contrast, the Canon lens, while not specified in weight, is designed with a robust build aimed at versatility across different shooting conditions.
The 7Artisans lens is constructed from 10 glass elements arranged in 8 groups, which enhances its optical quality. The use of metal in its construction not only improves durability but also provides a premium feel. The Canon lens focuses on functionality, featuring in-lens optical image stabilization that significantly reduces camera shake, particularly useful in dynamic shooting scenarios.
Optical Performance
Optically, the 7Artisans lens features a wide aperture range of F2.8 to F16 and a 225° ultra-wide angle, delivering a strong visual impact. This fisheye design reduces internal reflections, such as flaring and ghosting, ensuring high-quality images. The closest focusing distance of 0.085m (approximately 3.34 inches) allows for creative close-up shots, making it ideal for artistic photography.
On the other hand, the Canon lens offers a zoom range from 18mm to 150mm, making it suitable for various subjects, from landscapes to portraits. It incorporates advanced optical image stabilization with up to 4.5 stops of shake correction, enhancing sharpness in lower light conditions. This distinction in optical capabilities highlights the different photographic approaches of each lens.
Compatibility and Use Cases
The 7Artisans lens is specifically compatible with Sony E-mount APS-C mirrorless cameras, including models like the A6300, A6400, and A7 series. This specialization makes it a great choice for Sony users looking to explore fisheye photography. Its compact size and lightweight nature also make it suitable for travel and casual shooting.
Conversely, the Canon lens is designed for APS-C cameras with RF mounts and automatically adjusts for full-frame EOS R-series cameras, making it versatile for those who might upgrade their camera system. Its extensive zoom range allows for flexibility in shooting different types of photography, from wide-angle landscapes to close-up details, appealing to a broader audience.
Autofocus and Stabilization
The 7Artisans lens relies on manual focus, which may appeal to photographers who enjoy the control and precision that comes with it. However, this feature might be challenging for those who prefer the convenience of autofocus, particularly in fast-paced shooting scenarios.
In contrast, the Canon lens features a lead screw-type STM that provides smooth and quiet autofocus operation, ideal for capturing videos without distracting background noise. Its image stabilization system significantly enhances performance when shooting in motion, particularly in video mode, providing up to 6.5 stops of shake correction when paired with EOS R series cameras. This makes the Canon lens a strong contender for videographers and those who require reliable autofocus in their photography.
Price Comparison
The financial aspect is a crucial differentiator between these two lenses. The 7Artisans lens is priced at $149.00, catering to budget-conscious photographers or those looking for a specialized lens without a hefty investment. In contrast, the Canon lens, at $569.00, represents a higher-end option aimed at enthusiasts and professionals who require versatility and advanced features.
The price difference of $420 suggests that potential buyers must consider their specific needs and budget. While the 7Artisans lens is significantly more affordable, the Canon lens offers advanced technology that may justify the higher cost for serious photographers.
User Experience and Support
7Artisans provides excellent customer support, including a one-year free repair service from the date of purchase. This commitment to customer service enhances the overall user experience, making it a reliable choice for those new to manual focus lenses. Additionally, users have access to instructions that help optimize lens usage.
On the other hand, the Canon lens is backed by Canon’s reputation for quality and service, appealing to those who may have prior experience with Canon products. The combination of reliable autofocus and advanced image stabilization also contributes to a positive user experience, especially for those capturing video content.

The 7Artisans lens is a fantastic option for those seeking an affordable, lightweight, and specialized fisheye lens for Sony E-mount cameras.
