Price Comparison
The pricing of the Canon EF 50mm f/1.8 STM Lens and the TTArtisan 7.5mm F2.0 shows a notable difference. The Canon lens is priced at $155.99, while the TTArtisan lens is available for $139.00, making the TTArtisan about 11% cheaper. For photographers on a budget, this price difference could be a significant factor in their purchasing decision, especially if they are exploring creative styles that the TTArtisan lens specializes in.
Focal Length and Aperture
A key distinction between the two lenses is their focal lengths and maximum apertures. The Canon EF 50mm offers a focal length of 50mm with an aperture of f/1.8, making it a go-to for standard portrait and everyday photography. In contrast, the TTArtisan 7.5mm provides an ultra-wide 7.5mm focal length paired with a maximum aperture of f/2.0. This wider angle allows for unique compositions, particularly in landscape and architecture photography, where expansive views are essential. Each lens caters to different photography needs, from general use to specialized creative applications.
Autofocus and Manual Focus Capabilities
The autofocus features of these lenses also set them apart. The Canon EF 50mm f/1.8 STM utilizes a stepping motor (STM) for near-silent autofocus, which is beneficial for video recording and still photography alike. This feature provides smooth and accurate focusing without distracting noise. On the other hand, the TTArtisan 7.5mm F2.0 lens is a manual focus lens, which requires the photographer to focus manually. This can be an advantage for creative control but may not be as user-friendly for those accustomed to autofocus systems.
Creative Potential and Applications
When considering creative potential, the TTArtisan 7.5mm lens shines with its fisheye capabilities. It not only offers a 180° perspective but also allows for distinct visual effects, such as exaggerated distortion and close-up capabilities that can create humorous or artistic images. Canon's 50mm lens, while excellent for portraits and everyday shooting, does not provide the same level of creative distortion. Photographers who thrive on experimentation with perspective may find the TTArtisan lens more appealing for their artistic endeavors.
Compatibility with Camera Systems
Compatibility is another crucial factor to consider when choosing between these lenses. The Canon EF 50mm f/1.8 STM Lens is designed for Canon cameras, particularly full-frame and APS-C models, offering versatility across various Canon systems. In contrast, the TTArtisan 7.5mm F2.0 is specifically tailored for Sony APS-C models and also works with full-frame Sony cameras when APS-C mode is enabled. This focus on specific camera systems means that photographers must consider their existing gear when making a decision, as each lens is optimized for different brands.
Which should you buy?
Choosing between the Canon EF 50mm f/1.8 STM Lens and the TTArtisan 7.5mm F2.0 ultimately depends on your photography style and needs. If you are looking for a versatile, reliable lens for portraits and general photography, the Canon lens is an excellent choice with its superior autofocus capabilities and low-light performance. However, if you are drawn to creative photography, particularly with wide-angle and fisheye effects, the TTArtisan lens may be more suitable, offering unique perspectives at a lower price point. Each lens serves distinct purposes, and your choice should align with the type of photography you wish to pursue.
