The BENOISON lens is priced at $67.99, while the EF 85mm lens comes in at $77.59, making the BENOISON lens about 12% cheaper. Both lenses are manual focus, providing distinct user experiences tailored to different photography styles and needs.
Target Audience
The BENOISON Telephoto Lens is designed for wildlife and astronomical photography enthusiasts, offering a focal length range of 420-800mm. This makes it suitable for capturing distant subjects, such as animals or celestial bodies. In contrast, the EF 85mm f1.8 Portrait Lens is aimed at portrait photographers who value precise focus and the artistic qualities of bokeh. This lens is intended for users looking to achieve sharp, aesthetically pleasing images with a blurred background effect.
Compatibility and Mounts
When it comes to compatibility, the BENOISON Telephoto Lens is specifically made for Nikon DSLR cameras, including models like the D3500, D850, and D7500. It connects through an F mount and does not require a T adapter, simplifying its use. On the other hand, the EF 85mm Portrait Lens is compatible with a wide range of Canon DSLRs, including the Rebel series and more advanced models like the EOS 90D and 6D Mark II. This broad compatibility makes the Canon lens versatile for photographers who may own different models in the Canon ecosystem.
Lens Features
The BENOISON lens features a focal length of 420-800mm with a fixed aperture range of F/8.3-16, while the EF 85mm lens boasts a faster maximum aperture of F1.8. The larger aperture of the Canon lens allows for better low-light performance and more creative control over depth of field. Additionally, the BENOISON lens is noted for its robust construction and durability, making it a reliable choice for outdoor photography, especially in challenging conditions.
User Experience
Both lenses are manual focus, which can be both a challenge and an advantage. The BENOISON lens requires users to manually adjust the focus without electronic assistance, which can lead to learning opportunities for photographers. However, it may also present difficulties for beginners. The EF 85mm lens also emphasizes manual focus, encouraging photographers to take full creative control but requiring them to switch to manual mode on their cameras. This shared characteristic aims at users who appreciate the art of photography and are willing to invest time in mastering their tools.
Image Quality
The EF 85mm f1.8 lens is designed to deliver exceptional image quality with six rounded aperture blades that enhance the bokeh effect, producing dreamy backgrounds in portraits. The lens incorporates advanced optical technologies to minimize aberrations and glare, ensuring sharp images. The BENOISON lens, while designed for long-distance subjects, does not specifically highlight its image quality features. However, it is built with high-quality materials, which suggests a focus on durability and performance, especially for wildlife and lunar photography.
Price Comparison
The BENOISON lens is priced at $67.99, making it a more budget-friendly option compared to the $77.59 price tag of the EF 85mm lens. This price difference of approximately $9.60 can be significant for photographers who are just starting or those who are budget-conscious. Despite its lower price, the BENOISON lens offers a unique focal length that can be appealing for specific photography needs.
Which should you buy?
Choosing between the BENOISON Telephoto Lens and the EF 85mm f1.8 Portrait Lens ultimately depends on your photography goals. If you're focused on wildlife or astrophotography, the BENOISON lens offers a longer focal length at a lower price, making it an attractive option. However, if you're a portrait photographer looking for superior image quality and creative control, the EF 85mm lens justifies its higher price with its faster aperture and exceptional bokeh capabilities. Each lens serves a distinct purpose, so your choice should align with your specific photographic needs.
