7artisans 7. vs Rokinon

Overview

When it comes to ultra-wide-angle lenses, the 7artisans 7.5mm F2.8 II Fisheye Lens and the Rokinon 14mm f/2.8 IF ED Super Lens offer distinct advantages tailored to different photography needs. The 7artisans lens is designed for Sony E-mount cameras, while the Rokinon lens is compatible with Canon EF mounts. Pricing also highlights a significant difference, with the 7artisans lens retailing at $139.00 and the Rokinon lens priced at $231.25, making the former about 40% cheaper.

Design and Build Quality

The 7artisans 7.5mm F2.8 II features a robust all-metal body with a petal lens hood, ensuring durability and a premium feel. Its compact size enhances portability, making it ideal for travel. In contrast, the Rokinon lens is heavier, weighing 31.7oz (900g), which may be a consideration for users prioritizing lightweight gear. While both lenses boast a solid build, the 7artisans lens’s lighter weight and compactness offer an edge for photographers on the move.

Optical Performance

In terms of optical design, the 7artisans lens incorporates 9 groups and 11 elements, including two ED lenses that effectively minimize chromatic aberration. It provides a remarkable 190° ultra-wide viewing angle, ideal for expansive landscapes and immersive 360° VR panoramas. Conversely, the Rokinon lens features 14 elements in 10 groups, optimizing sharpness and clarity across the frame, particularly suitable for landscapes and astrophotography. While the Rokinon offers a narrower angle of view at 115.7°, its advanced optical design still delivers stunning results.

Aperture and Low-Light Performance

The 7artisans lens features a large F2.8 aperture, allowing more light to enter, which is beneficial for low-light conditions and achieving a shallow depth of field. This is particularly advantageous for capturing starry skies or auroras. On the other hand, the Rokinon also boasts a fast f/2.8 maximum aperture, enabling excellent low-light performance. Both lenses excel in this area, but the 7artisans lens may provide an edge in ultra-wide scenarios due to its fish-eye characteristics.

Compatibility

The 7artisans 7.5mm F2.8 II is specifically designed for Sony E-mount cameras, including a wide range of models such as the A7 series. This makes it a perfect choice for users heavily invested in Sony's ecosystem. In contrast, the Rokinon 14mm lens is compatible with Canon EF mounts, making it versatile for various Canon cameras and even some mirrorless models when using the right adapters. Compatibility will largely dictate which lens a photographer should consider based on their existing camera system.

Use Cases

The intended use cases for each lens highlight their strengths. The 7artisans 7.5mm F2.8 II is ideal for landscape, travel, and underwater photography, thanks to its extreme wide-angle and fisheye capabilities. It's particularly suited for creative shots and immersive experiences. Meanwhile, the Rokinon 14mm f/2.8 excels in astrophotography and real estate photography, where capturing expansive scenes with sharp detail is critical. Each lens serves different niches, making the choice more about the photographer's specific needs.

Price Consideration

Pricing significantly influences the decision between the two lenses. The 7artisans lens is available for $139.00, making it an excellent value given its features and performance. In contrast, the Rokinon lens retails at $231.25, approximately 66% more expensive. For budget-conscious photographers or those just starting, the 7artisans lens presents a compelling option without sacrificing quality, especially for ultra-wide-angle applications.

Which should you buy?

Choosing between the 7artisans 7.5mm F2.8 II Fisheye Lens and the Rokinon 14mm f/2.8 IF ED Super Lens ultimately depends on your specific requirements. If you're a Sony user looking for a lightweight, cost-effective lens with a wide viewing angle for creative photography, the 7artisans lens is an excellent choice. However, if you're invested in the Canon ecosystem and looking for superior edge-to-edge sharpness for landscape or astrophotography, the Rokinon lens justifies its higher price. Each lens has unique strengths that cater to different photographic styles and preferences.
