Price Comparison
The Canon EF 50mm f/1.8 STM Lens is priced at $169.00, while the TTArtisan AF 27mm F2.8 is slightly cheaper at $159.99, making it about 17% less expensive. While both lenses are positioned as great options for different camera systems, the pricing may influence which lens you choose depending on your budget. The price difference of just $9.01 might seem minor, but it could sway potential buyers looking for more value.
Brand Reputation
Canon is a well-established brand known for its high-quality photographic equipment, including lenses that have garnered a solid reputation among both amateur and professional photographers. The Canon EF 50mm f/1.8 STM Lens benefits from years of refinement and has a loyal following. On the other hand, TTArtisan is a newer brand that has been gaining traction for its innovative designs and competitive pricing. While the TTArtisan AF 27mm F2.8 is well-received, it doesn’t yet carry the same level of trust that Canon enjoys.
Compatibility
The Canon EF 50mm f/1.8 STM Lens is designed for Canon EOS cameras, making it a versatile choice for photographers who own full-frame or APS-C sensor cameras. It effectively functions as an 80mm lens on APS-C cameras, which is excellent for portraits and low-light situations. In contrast, the TTArtisan AF 27mm F2.8 is specifically designed for Fujifilm X-Mount cameras, including popular models like the X-T10 and X-T4. If you own a Fujifilm camera, the TTArtisan lens is the only option that will fit your needs.
Aperture and Low-Light Performance
The Canon EF 50mm f/1.8 STM boasts a maximum aperture of f/1.8, allowing for excellent low-light performance and creating a beautiful background blur. This feature is particularly beneficial for capturing portraits and nighttime photography, making it a favorite for many photographers. In comparison, the TTArtisan AF 27mm F2.8 has a maximum aperture of f/2.8, which is decent but does not perform as well in low-light conditions as the Canon lens. The wider aperture of the Canon lens contributes to sharper images with less motion blur, giving it an edge for low-light and artistic shots.
Focusing Mechanism
The Canon EF 50mm f/1.8 STM utilizes a stepping motor (STM) that provides near-silent autofocus, which is ideal for shooting videos where sound quality is crucial. Its fast and smooth autofocus makes it a reliable option for capturing fleeting moments. In contrast, the TTArtisan AF 27mm F2.8 also features a stepping motor and supports eye-detection autofocus, which can be advantageous for portrait shooting. However, the Canon lens is known for its more refined focusing capabilities, especially in various shooting conditions, including low light.
Build Quality and Design
The Canon EF 50mm f/1.8 STM is compact and lightweight, making it an excellent walk-around lens. It features a rugged metal mount and an improved exterior design that enhances manual focus adjustments. This lens is known for its robust build quality despite its budget-friendly price point. The TTArtisan AF 27mm F2.8 is also designed to be compact and easy to carry, but it includes a unique feature of a click aperture ring that allows for more convenient shooting, enabling quick adjustments without going into camera settings. While both lenses are portable, the Canon lens has a slight advantage in overall durability.
Image Quality
The Canon EF 50mm f/1.8 STM is celebrated for its sharpness and excellent color balance, helped by its updated lens coatings that minimize ghosting and flare. Its circular 7-blade design contributes to beautiful bokeh, enhancing portrait photography. The TTArtisan AF 27mm F2.8, while capable of producing good images, may not achieve the same level of sharpness and background blur as the Canon lens due to its narrower aperture. Therefore, for those prioritizing image quality, especially in diverse lighting conditions, the Canon lens stands out.
Which should you buy?
Choosing between the Canon EF 50mm f/1.8 STM Lens and the TTArtisan AF 27mm F2.8 depends largely on your camera system and specific needs. If you own a Canon camera and seek superior low-light performance, sharpness, and a well-established brand reputation, the Canon lens is the clear winner. However, if you are a Fujifilm user looking for a budget-friendly option with unique features like eye-detection autofocus, the TTArtisan lens offers great value for its price. Ultimately, the decision should align with your specific photographic requirements and your existing camera system.
