Overview of the Products
The BENOISON Telephoto Lens for Nikon is priced at $67.99, while the TTArtisan 7.5mm F2.0 for Sony comes in at $139.00, making the BENOISON lens about 51% cheaper. Each lens caters to specific photography needs: BENOISON focuses on long-distance shots, while TTArtisan offers a unique fisheye perspective. This article will delve into the features, compatibility, and applications of these two lenses to highlight their strengths and weaknesses.
Design and Build Quality
The BENOISON Telephoto Lens boasts a robust construction made from high-quality materials, emphasizing durability for outdoor shooting, especially in wildlife and moon photography. On the other hand, the TTArtisan 7.5mm lens features a compact design suited for mirrorless cameras, allowing for easy portability. While both lenses are manual focus, the BENOISON is designed for longer focal lengths (420-800mm) with a fixed aperture range of F/8.3-16, which might limit versatility compared to the TTArtisan's wider F/2.0 aperture. This wider aperture allows for better performance in low-light conditions, enhancing the overall usability of the TTArtisan lens.
Compatibility
Compatibility is a critical factor when choosing a lens. The BENOISON lens is specifically designed for Nikon DSLR cameras, compatible with a wide range of models including D3500, D850, and D7500, among others. In contrast, the TTArtisan lens is tailored for Sony APS-C models and can also be used with full-frame cameras in APS-C mode. This extensive compatibility for both products allows photographers to choose based on their existing gear, but users of Nikon cameras will find no option comparable to the BENOISON lens.
Focusing Mechanism
Focusing mechanisms differ significantly between the two lenses. The BENOISON Telephoto Lens is a manual focus lens, requiring users to manually adjust the focus ring to achieve sharp images. It lacks autofocus and electronic contacts, which can be a drawback for those accustomed to modern autofocus systems. On the other hand, the TTArtisan also operates with manual focus but offers a unique close-up capability with a minimum focusing distance of just 4 inches. This feature can provide creative opportunities for exaggerated, humorous visual effects that are absent in the BENOISON lens.
Photography Applications
When it comes to photography applications, these lenses serve distinct purposes. The BENOISON Telephoto Lens is ideal for capturing distant subjects like wildlife or celestial bodies, thanks to its super telephoto focal length. Its non-adjustable aperture might limit its use under varying lighting conditions, but for dedicated telephoto work, it is well-suited. Conversely, the TTArtisan 7.5mm lens excels in offering a 180° diagonal fisheye perspective, making it perfect for creative projects, astrophotography, and capturing wide landscapes. Each lens shines in its respective domain, but photographers must consider how they intend to use the lens in their work.
Price Comparison
The BENOISON lens is currently available for $67.99, which is significantly lower than the TTArtisan's price of $139.00. This price difference of $71.01 represents about a 51% savings for the BENOISON lens. For photographers on a budget or those just starting, the affordability of the BENOISON lens may be highly attractive. However, the higher price of the TTArtisan reflects its advanced features, such as a wider aperture and unique fisheye capabilities, which may justify the investment for more experienced photographers seeking creative options.
User Experience
User experience can vary widely between these two lenses. The BENOISON Telephoto Lens requires users to be comfortable with manual focusing, which can be challenging for beginners unfamiliar with manual settings. The lens operates in manual mode, leading to potential frustrations if users forget to switch modes. In contrast, the TTArtisan lens, while also manual, offers a more intuitive approach to creative photography with its extreme wide-angle capabilities and low-light performance. This could make the TTArtisan more appealing to those looking for flexibility and ease of use in their photography.
Which should you buy?
Ultimately, the decision between the BENOISON Telephoto Lens for Nikon and the TTArtisan 7.5mm F2.0 for Sony hinges on individual needs and preferences. If your focus lies in telephoto photography, particularly for wildlife or lunar shots, the BENOISON lens provides an excellent and budget-friendly option. However, if you're looking for versatility, creative shooting perspectives, and low-light capabilities, the TTArtisan lens justifies its higher price tag with unique features that can elevate your photography. Consider your existing equipment, budget, and specific photography goals when making your choice.
