Design and Build Quality
The 37mm 0.25X Super Fisheye Lens is made from high-quality aluminum alloy and optical glass, ensuring durability and a sturdy feel. It weighs approximately 228 grams, making it lightweight and portable, which is ideal for photographers on the go. In contrast, the TTArtisan AF 27mm F2.8 lens does not specify its materials, but it features a compact design with an STM (stepping motor) that enhances its autofocus performance. Both lenses are designed with usability in mind, but the Super Fisheye offers a more specialized structure for creative photography.
Compatibility with Cameras
The 37mm 0.25X Super Fisheye Lens is compatible with all 37mm caliber camera lenses, making it versatile for users who own cameras with this specific lens size. On the other hand, the TTArtisan AF 27mm F2.8 lens is specifically designed for Fujifilm X-mount cameras, including models like the X-T10, X-T2, and X-T30. This focused compatibility may limit its user base but provides enhanced performance for those with compatible cameras, especially given its advanced features like eye-detection autofocus.
Image Quality and Performance
The Super Fisheye Lens offers a magnification effect of 0.25X, which is perfect for capturing wide-angle shots with a unique fisheye perspective. It is particularly suited for creative photography and special shooting occasions. The TTArtisan AF 27mm F2.8 lens, however, boasts a large aperture of F2.8, which allows for better low-light performance and a pleasing bokeh effect in images. Its closest focus distance is 0.35 meters, enabling detailed close-up shots. Therefore, the image quality and performance will depend heavily on the intended use—creative versus general photography.
Ease of Use
The 37mm 0.25X Super Fisheye Lens includes a storage bag and a dust removal cloth, emphasizing ease of transport and maintenance. Its lightweight design makes it convenient for outdoor photography. The TTArtisan lens features a click aperture ring for quick adjustments during shooting and supports firmware upgrades via a USB-C interface, which adds a layer of convenience for users who want to keep their lens updated. Therefore, while both lenses offer ease of use, the TTArtisan lens provides more advanced features for a streamlined shooting experience.

It can be separated into two parts, allowing for a macro lens that provides a magnification effect of 12.5 times, suitable for close-up shots. This makes it an excellent choice for photographers who enjoy experimenting with different perspectives. The TTArtisan AF 27mm F2.8 lens, however, incorporates features like eye-detection autofocus and an STM for smoother focusing, enhancing its usability in various shooting situations. Each lens brings distinct advantages to the table, showcasing their special features tailored to different photography styles.
Price Comparison
