The TTArtisan AF 27mm F2.8 is priced at $159.99, while the YONGNUO YN50mm F1.8C is more budget-friendly at $132.29, making it about 17% cheaper. Both lenses cater to different camera systems, with the TTArtisan designed for Fujifilm X-mount cameras and the YONGNUO tailored for Canon EF mount cameras. This article dives deeper into the features, performance, and usability of each lens to help you make an informed choice.
Design and Build Quality
In terms of design, the TTArtisan AF 27mm F2.8 features a sleek, compact construction ideal for portability. Its STM stepping motor allows for smooth focusing, making it a great option for shooting videos as well as stills. On the other hand, the YONGNUO YN50mm F1.8C, being a prime lens, boasts a classic look and build, measuring just 2 inches in length. Both lenses are lightweight and easy to handle, but the TTArtisan’s design benefits from modern features like a USB-C interface for firmware upgrades, adding a layer of versatility to its build.
Optical Performance
When it comes to optical performance, the YONGNUO YN50mm F1.8C excels with its large aperture of f/1.8, which provides better low-light capabilities and improved edge-to-edge sharpness. This can be a significant advantage for photographers who frequently shoot in dimly lit environments. In contrast, the TTArtisan AF 27mm F2.8, while having a respectable f/2.8 aperture, does not match the low-light performance of the YONGNUO. However, it offers a unique close-up shooting capability with a minimum focus distance of 0.35 meters, allowing for detailed shots.
Autofocus Capabilities
The autofocus systems of both lenses are designed to meet the needs of modern photographers. The TTArtisan AF 27mm F2.8 utilizes an STM stepping motor, which is known for its quiet and smooth operation, particularly beneficial for videographers. It also supports eye-detection autofocus, making it easier to track subjects during photography. Conversely, the YONGNUO YN50mm F1.8C supports both autofocus and manual focus, providing versatility depending on the shooting situation. While both lenses are effective, the TTArtisan offers more advanced autofocus features, especially for portrait photography.
Compatibility with Camera Systems
Compatibility is a crucial factor to consider. The TTArtisan AF 27mm F2.8 is specifically designed for a wide range of Fujifilm X-mount cameras, including popular models like the X-T10, X-T2, and X-T4. This makes it an ideal choice for Fujifilm users looking to expand their lens collection. In contrast, the YONGNUO YN50mm F1.8C is compatible with Canon EF mount cameras, such as the 5D, 7D, and 60D series. Your choice will ultimately depend on the camera system you own, as each lens is tailored to different brands.
Bokeh and Artistic Effects
For those who appreciate bokeh and artistic effects in their photography, the YONGNUO YN50mm F1.8C shines with its f/1.8 aperture, allowing for a shallower depth of field. This results in beautiful background blur, enhancing portrait shots and making subjects stand out. The TTArtisan AF 27mm F2.8, while capable of producing decent bokeh, is limited by its f/2.8 aperture. Thus, if bokeh is a primary concern, the YONGNUO lens may offer a more satisfying experience.
Price and Value for Money
When comparing price points, the YONGNUO YN50mm F1.8C is the more economical choice at $132.29, compared to the TTArtisan AF 27mm F2.8 at $159.99. This price difference of approximately $27 may sway budget-conscious shoppers. However, it’s essential to consider the specific features and performance each lens provides. While the TTArtisan may be pricier, its advanced autofocus features and close-up capabilities could justify the extra cost for Fujifilm users.
User Experience and Feedback
User feedback plays a significant role in evaluating the overall experience with each lens. The TTArtisan AF 27mm F2.8 has received praise for its smooth autofocus and compact design, making it a favorite among Fujifilm users who prioritize portability. Meanwhile, the YONGNUO YN50mm F1.8C is appreciated for its affordability and performance, particularly in low light. Both lenses have their strengths, but user preferences may vary based on their specific photography needs and camera systems.
Which should you buy?
Deciding between the TTArtisan AF 27mm F2.8 and the YONGNUO YN50mm F1.8C ultimately depends on your camera system and photography style. If you own a Fujifilm camera and value advanced autofocus capabilities and close-up shooting, the TTArtisan is worth the investment. Conversely, if you are a Canon user seeking a budget-friendly lens with excellent low-light performance and beautiful bokeh, the YONGNUO is an outstanding choice. Each lens offers unique features that cater to different needs, making either a solid addition to your gear.
