Both lenses target different photography needs, appealing to varied user preferences and styles.
Design and Build Quality
The 37mm 0.25X Super Fisheye Lens features a compact design made from aluminum alloy and optical glass, ensuring durability while maintaining a lightweight profile. It weighs approximately 228 grams and comes with a storage bag for easy transport. In contrast, the Tamron 24mm F/2.8 Di III OSD M1:2 Lens is also designed to be compact and lightweight, weighing only 7.6 ounces (about 215 grams) with a length of 2.5 inches. Both lenses are built to withstand outdoor conditions, but the Tamron lens benefits from a moisture-resistant construction and a dirt-resistant fluorine coating, enhancing its usability in various settings.
Optical Performance
When it comes to optical performance, both lenses excel in their respective categories. The 37mm 0.25X Super Fisheye Lens delivers a wide fisheye effect, suitable for special photography occasions, while also offering a separate macro lens that provides a 12.5 times magnification effect for close-up shots. Conversely, the Tamron 24mm lens is designed for a wider field of view, making it ideal for landscapes and urban scenes. Its maximum magnification ratio of 1:2 allows for detailed macro-style shots, and the lens elements work to minimize aberrations, providing sharp images across the entire frame.
Versatility
The versatility of a lens can heavily influence a photographer's choice. The 37mm 0.25X Super Fisheye Lens is specifically tailored for fisheye effects and macro close-up photography, making it excellent for creative shots and unique angles. However, it is limited to 37mm camera lenses, which may restrict its usability across different camera models. On the other hand, the Tamron 24mm lens is designed for Sony full-frame and APS-C E-Mount mirrorless cameras, accommodating a broader range of photography styles, from candid snapshots to expansive landscapes.
