Overview of the BENOISON Telephoto Lens and Canon EF 50mm Lens
The BENOISON Telephoto Lens for Nikon is priced at $67.99, while the Canon EF 50mm f/1.8 STM Lens comes in at $155.99, making the BENOISON lens about 56% cheaper than the Canon option. This significant price difference plays a key role in determining which lens might be the better choice for photographers, depending on their needs and budget.
BENOISON's lens is a manual focus telephoto lens with a focal length range of 420-800mm, ideal for capturing distant subjects like wildlife and the moon. On the other hand, the Canon lens is a prime lens with a fixed focal length of 50mm and a maximum aperture of f/1.8, making it suitable for portrait and low-light photography. This comparison sheds light on how each lens serves different photographic purposes.
Intended Use and Versatility
The intended use of each lens is quite distinct, with the BENOISON lens catering primarily to long-distance photography, while the Canon lens excels in everyday scenarios. The BENOISON Telephoto Lens is specifically designed for wildlife and landscape photography, allowing users to reach distant subjects with its extensive zoom range. Its robust construction also suggests durability for outdoor use.
Conversely, the Canon EF 50mm lens is great for portraits and general photography, especially in low-light conditions due to its wide maximum aperture of f/1.8. This lens offers versatility for various shooting environments, making it an excellent choice for both amateur and professional photographers alike.
Focus Mechanism and Ease of Use
A critical difference between the two lenses lies in the focus mechanism. The BENOISON Telephoto Lens operates with manual focus, which requires users to manually turn the focus ring. This can be challenging, particularly for beginners, as it necessitates setting the camera to manual mode to avoid errors.
In contrast, the Canon EF 50mm lens features a stepping motor (STM) that provides near-silent autofocus performance. This feature makes it user-friendly, especially for capturing video or action shots, as it allows for smooth focusing without the noise typically associated with lenses that have autofocus. The ease of use with the Canon lens is ideal for those who prefer a more straightforward shooting experience.
Aperture and Low-Light Performance
When it comes to aperture and low-light performance, the BENOISON lens has a fixed aperture that ranges from f/8.3 at 420mm to f/16 at 800mm, which may limit its effectiveness in low-light situations. This non-adjustable aperture makes it challenging for photographers who require flexibility in varying lighting conditions.
On the other hand, the Canon EF 50mm lens boasts a maximum aperture of f/1.8, allowing for greater control over depth of field and better performance in low-light environments. This feature makes the Canon lens particularly appealing for portrait photography, where a shallow depth of field can help isolate subjects from the background.
Focal Length and Field of View
Focal length is another significant factor that differentiates these two lenses. The BENOISON Telephoto Lens offers an impressive focal length range of 420-800mm, providing a narrow field of view ideal for capturing distant subjects. This makes it perfect for wildlife photographers who need to maintain a safe distance from their subjects.
In contrast, the Canon EF 50mm lens has a standard focal length of 50mm, which translates to an effective focal length of 80mm on APS-C cameras. This makes it more suited for general photography, including portraits and street photography, where a wider field of view is often beneficial. The choice of focal length will largely depend on the specific photographic needs of the user.
Build Quality and Durability
In terms of build quality and durability, the BENOISON Telephoto Lens is described as being constructed with high-quality materials, making it robust and long-lasting. This durability is particularly important for photographers who often shoot in rugged outdoor environments.
The Canon EF 50mm lens, while also well-built, focuses more on portability and lightweight design, making it a convenient option for everyday carry. Photographers who prioritize a compact setup may find the Canon lens easier to include in their camera bag without adding significant weight.
Price Point and Value for Money
At $67.99, the BENOISON Telephoto Lens offers an attractive price point for those who need a long-range lens without breaking the bank. Its price is significantly lower than the Canon lens, which retails for $155.99. This price gap of $88 signifies a considerable difference in investment, making the BENOISON lens a more accessible option for hobbyists or those just starting in photography.
However, the Canon EF 50mm lens provides excellent value for its price through its exceptional low-light performance and ease of use. While it is more expensive, photographers looking for a reliable and versatile lens may find the investment worthwhile for its quality and features.
Which should you buy?
Choosing between the BENOISON Telephoto Lens and the Canon EF 50mm lens ultimately depends on your specific photography needs. If you're focused on wildlife or long-distance photography and require an affordable option, the BENOISON lens is a compelling choice. However, if you prefer a lens that excels in low-light conditions and offers effortless autofocus, the Canon EF 50mm lens is likely the better investment despite its higher price point. Each lens serves distinct purposes, so your final decision should be based on what type of photography you intend to pursue.
