Overview of the BENOISON Telephoto Lens and Canon RF-S18-45mm Lens
The BENOISON Telephoto Lens for Nikon is priced at $67.99, while the Canon RF-S18-45mm Lens comes in at $87.00, making the BENOISON lens about 22% cheaper. Both lenses cater to different photography needs—one focusing on extreme telephoto capabilities, while the other offers versatile zoom for everyday photography.
Design and Build Quality
The BENOISON Telephoto Lens features a robust construction tailored for durability, specifically designed for Nikon DSLR users. Its manual focus mechanism demands a hands-on approach, which can appeal to those who enjoy the craftsmanship of photography. In contrast, the Canon RF-S18-45mm Lens is compact and lightweight, designed with a clever lens retraction mechanism, making it highly portable. While the BENOISON lens is bulkier and more suited for stationary subjects like wildlife or the moon, the Canon lens is ideal for those looking for convenience and ease of use in various settings.
Focal Length and Versatility
The BENOISON Telephoto Lens offers an impressive focal length range of 420-800mm, which is ideal for capturing distant subjects, particularly in wildlife photography. Its fixed aperture of F/8.3-16 limits its versatility in low-light conditions but provides excellent reach for outdoor photography. On the other hand, the Canon RF-S18-45mm Lens covers a more modest zoom range of 18-45mm, which is versatile for general photography, including landscapes and portraits. This makes the Canon lens more suitable for everyday use, while the BENOISON lens excels in specialized shooting scenarios.
Autofocus and Image Stabilization
The BENOISON Telephoto Lens operates solely in manual focus mode, which can be a drawback for photographers who prefer the convenience of autofocus. Without electronic contacts, users must rely on their skills to achieve the desired focus, which might not be ideal for fast-paced shooting scenarios. Conversely, the Canon RF-S18-45mm Lens features Optical Image Stabilization that provides up to 4 stops of shake correction, enhancing image clarity, especially in low-light situations. With automatic adjustments for APS-C sensors, the Canon lens offers a more user-friendly experience, particularly beneficial for casual photographers and videographers.
Compatibility
The BENOISON Telephoto Lens is specifically designed for Nikon DSLR cameras, boasting compatibility with a wide range of models, including D3500, D850, and D7500. This makes it a dedicated choice for Nikon users looking to expand their lens collection. Meanwhile, the Canon RF-S18-45mm Lens is tailored for APS-C cameras with the RF mount, and it can also adapt to full-frame EOS R-series cameras. This dual compatibility gives the Canon lens an edge for photographers who may switch between camera systems in the future.
Performance in Different Environments
The BENOISON Telephoto Lens shines in environments where long-distance shots are required, making it perfect for capturing wildlife or celestial events. However, its manual focus can hinder performance in dynamic settings. On the other hand, the Canon RF-S18-45mm Lens is designed to perform well in everyday situations, with its lightweight design and stabilization features allowing it to adapt to various lighting conditions. This versatility makes the Canon lens a better option for those who want a reliable lens for diverse photographic environments.
Price Comparison
The BENOISON Telephoto Lens is available for $67.99, while the Canon RF-S18-45mm Lens retails for $87.00, showing a price difference of $19.01. This makes the BENOISON lens approximately 22% less expensive than the Canon option. However, the price difference reflects their distinct features and target audiences, with the BENOISON lens catering to specific telephoto needs and the Canon lens offering more general versatility and ease of use.
Which should you buy?
Choosing between the BENOISON Telephoto Lens and the Canon RF-S18-45mm Lens ultimately depends on your photography needs. If you're a Nikon DSLR user looking for an affordable telephoto option specifically for wildlife or distant subjects, the BENOISON lens is a strong choice. However, if you prioritize versatility, portability, and ease of use in everyday photography, the Canon lens stands out. Given its compact design, excellent image stabilization, and broader compatibility, the Canon RF-S18-45mm Lens may be the better investment for most photographers.
