BENOISON Telephoto Lens for Nikon - F Lens 420-Canon EF

Price Comparison

When it comes to price, the BENOISON Telephoto Lens for Nikon is significantly cheaper than the Canon EF 50mm f/1.8 STM Lens, retailing at $67.99 compared to Canon's $169.00. This places the BENOISON lens at about 60% lower in price than its competitor, making it a more budget-friendly option for photographers looking to expand their lens collection without breaking the bank. However, the lower price of the BENOISON lens comes with trade-offs in features and functionality, which we will explore further in this comparison.

Lens Type and Purpose

The BENOISON Telephoto Lens for Nikon is a manual focus lens designed primarily for wildlife and moon photography with a focal length of 420-800mm, while the Canon EF 50mm f/1.8 STM Lens is a versatile prime lens with a focal length of 50mm. The BENOISON lens is ideal for capturing distant subjects, making it suitable for specific niche photography. In contrast, the Canon lens excels in versatility, suitable for portraits, action shots, and low-light conditions thanks to its f/1.8 maximum aperture. This means the Canon lens provides a wider range of creative possibilities, particularly in varied shooting environments.

Autofocus Capability

A major distinction between the two lenses is their autofocus capabilities. The BENOISON Telephoto Lens is a manual focus lens, requiring users to manually adjust the focus, which can be challenging for fast-moving subjects. This lens lacks electronic contacts and autofocus motors, necessitating the use of the camera in manual mode. On the other hand, the Canon EF 50mm f/1.8 STM Lens features a stepping motor that enables near-silent autofocus, making it suitable for both still photography and videography. This key difference in focus technology could greatly impact your shooting experience, especially if you often capture moving subjects or video.

Aperture and Low-Light Performance

The BENOISON lens has a fixed aperture range of f/8.3 to f/16, which limits its performance in low-light conditions compared to the Canon lens, which boasts a maximum aperture of f/1.8. The larger aperture of the Canon lens allows for significantly more light to enter, making it ideal for low-light scenarios such as indoor portraits or evening photography. This capability not only enhances the quality of images captured in dim conditions but also allows for a shallower depth of field, resulting in aesthetically pleasing background blur—an effect that is particularly desirable in portrait photography.

Build Quality and Design

In terms of build quality, the BENOISON Telephoto Lens is constructed with durability in mind, designed to withstand the rigors of outdoor photography, particularly for wildlife enthusiasts. Its robust construction is complemented by a filter size of 62mm. In contrast, the Canon EF 50mm f/1.8 STM Lens is compact and lightweight, weighing approximately 5.6 oz. This makes it an excellent choice for photographers who prioritize portability and ease of use. While both lenses are well-built, the choice between them may depend on whether you prioritize ruggedness for outdoor shooting or the convenience of a lightweight design.

Compatibility

The BENOISON Telephoto Lens is exclusively compatible with Nikon DSLR cameras, with a wide range of models supported, including D3500, D850, and D7500. This lens is not designed for use with other brands. Conversely, the Canon EF 50mm f/1.8 STM Lens is tailored for Canon cameras, making it a versatile option for Canon users. If you own a Nikon DSLR, the BENOISON lens will serve you well, but Canon users will find the EF 50mm f/1.8 STM to be the clear choice for seamless compatibility.

Image Quality

When considering image quality, the Canon EF 50mm f/1.8 STM Lens is designed to deliver sharp images with excellent color balance and minimized ghosting and flare, thanks to its updated lens coatings and construction of six elements in five groups. The BENOISON lens, while capable of producing quality images at long distances, may not achieve the same level of sharpness and color fidelity, particularly in challenging lighting conditions due to its narrower aperture range. Photographers seeking high-quality, consistent results, especially in varied lighting, may lean towards the Canon lens.

Which should you buy?

Choosing between the BENOISON Telephoto Lens for Nikon and the Canon EF 50mm f/1.8 STM Lens ultimately depends on your specific photography needs. If you are a Nikon user looking for an affordable telephoto option for wildlife or moon photography, the BENOISON lens at $67.99 is a compelling choice. However, for those who prioritize versatility, autofocus capabilities, and low-light performance, the Canon lens, priced at $169.00, stands out as a superior option. Each lens serves different purposes; therefore, consider what features are most important for your photography style before making a decision.
