Comparison of Build Quality
When it comes to build quality, both the 37mm Super Fisheye Lens and the YONGNUO YN35mm F2 Lens are made from durable materials. The 37mm lens is constructed from aluminum alloy and optical glass, ensuring sturdiness and longevity. This lens weighs approximately 228g, making it lightweight and easy to handle.
In contrast, the YONGNUO lens features a chrome high precision metal bayonet, which improves the fit and durability of the lens. While the specific weight of the YONGNUO lens is not mentioned, its dimensions are 73mm in diameter and 59mm in length, which may suggest a more substantial build due to its additional features. Overall, both lenses exhibit solid construction, but the choice may depend on personal preferences regarding weight and handling.
Versatility in Photography
The 37mm Super Fisheye Lens excels in versatility, particularly with its dual functionality as both a fisheye lens and a macro lens. The removable macro lens allows for close-up photography with a significant magnification effect, which is perfect for capturing intricate details. This lens is ideal for creative shooting occasions, such as landscapes or artistic portraits.
On the other hand, the YONGNUO YN35mm F2 Lens is also versatile but in a different context. It supports various camera shooting modes and displays aperture data in the EXIF information, making it suitable for a wide range of photography styles. Its fast aperture of F/2 is excellent for low-light conditions, providing flexibility for indoor or nighttime photography. While both lenses offer versatility, their applications cater to different styles and preferences.
Optical Performance
In terms of optical performance, the YONGNUO YN35mm F2 Lens is designed to deliver superior quality, particularly with its multi-coated lenses that improve light transmission and reduce unwanted artifacts such as ghosting and flare. This lens is particularly well-suited for capturing sharp images in challenging lighting conditions, thanks to its fast aperture.
Conversely, while the 37mm Super Fisheye Lens provides a unique fisheye effect that can create stunning visuals, its optical performance is more specialized for wide-angle shots and artistic effects. The 0.25X magnification provides a distinct look, but it may not match the YONGNUO's capabilities in terms of low-light performance or sharpness. For photographers prioritizing optical quality, the YONGNUO lens may be the better option.
Portability and Convenience
The 37mm Super Fisheye Lens is designed with portability in mind. It includes a storage bag and is lightweight, making it convenient for photographers who need to travel or move quickly between locations. Its compact size allows for easy storage in a camera bag, ensuring that it is always ready for spontaneous photography sessions.
In comparison, while the YONGNUO YN35mm F2 Lens is likely portable given its fixed design, it does not specifically mention any included carrying accessories. However, its sturdier build may add some weight, which could impact how easily it is transported. If portability is a key factor, the 37mm lens has a clear advantage with its thoughtful design.
Price Comparison
Price is a significant factor when choosing between these two lenses. The 37mm Super Fisheye Lens is available for $52.35, making it an attractive option for budget-conscious photographers. In contrast, the YONGNUO YN35mm F2 Lens is priced at $106.00, which is about 102% more expensive than the fisheye lens. This considerable price difference might lead many to consider whether the additional features and optical performance justify the higher cost.
For photographers just starting or those looking to venture into specialized photography styles without a significant financial commitment, the 37mm lens is a compelling choice. However, for those seeking higher optical quality and versatility, the YONGNUO may be worth the investment.
Which should you buy?
Choosing between the 37mm 0.25X Super Fisheye Lens and the YONGNUO YN35mm F2 Lens ultimately depends on your photography needs and budget. If you are looking for an affordable, lightweight option that offers unique creative possibilities with a fisheye effect, the 37mm lens is an excellent choice.
