Price Comparison

The TTARTISAN AF 27mm f2.8 is priced at $159.99, while the YONGNUO YN50mm F1.8 is significantly cheaper at $82.00, making it about 48% less expensive. This substantial price gap may influence budget-conscious photographers looking for an effective lens without breaking the bank. The affordability of the YONGNUO could make it a more appealing option for beginners or those who want to expand their lens collection without a hefty investment. Conversely, the TTARTISAN may justify its higher price with features tailored for more advanced users or specific photography styles.

Design and Build Quality

In terms of design, the TTARTISAN AF 27mm f2.8 stands out with its ultra-compact pancake design, making it highly portable and ideal for travel. Its sleek and exquisite appearance not only enhances aesthetics but also adds to the convenience of carrying it around. In contrast, the YONGNUO YN50mm F1.8, while functional, does not emphasize compactness in the same way. Its build is standard for a lens of its type, suitable for various shooting scenarios but lacking the compact appeal of the TTARTISAN. This difference in design may cater to different user preferences, particularly for those prioritizing portability.

Focusing Capabilities

Focusing capabilities differ notably between the two lenses. The TTARTISAN AF 27mm features an STM stepping motor that provides smooth and silent autofocus, along with an eye recognition focus feature that aids in capturing sharp images of subjects' faces. This technology is beneficial for videographers and portrait photographers. On the other hand, the YONGNUO YN50mm also supports auto focus and manual focus modes, but its focusing system does not include advanced features like eye tracking. For photographers who prioritize quick and accurate focus, especially in dynamic situations, the TTARTISAN could be the better option.

Aperture and Low-Light Performance

When it comes to aperture, the YONGNUO YN50mm boasts a large aperture of F1.8, allowing for excellent low-light performance and the ability to create a beautiful bokeh effect, making it ideal for portrait photography. The TTARTISAN AF 27mm, while not as wide at F2.8, still provides decent low-light capabilities but may not achieve the same level of background blur. The difference in maximum aperture can significantly impact shooting in challenging lighting conditions, making the YONGNUO a preferable choice for those who often shoot in dim environments.

Features and Usability

The TTARTISAN AF 27mm comes equipped with several user-friendly features, including a clicked aperture ring for quick adjustments and a USB-C interface for firmware upgrades, enhancing its usability over time. These features cater to photographers looking for a more interactive experience with their equipment. In comparison, the YONGNUO YN50mm offers a focus distance indicator and supports multiple camera shooting modes, which adds to its versatility. However, it lacks some of the more innovative features found in the TTARTISAN. Users may find the additional conveniences of the TTARTISAN beneficial for a more efficient shooting process.

Compatibility

Compatibility is another key consideration when choosing between these lenses. The TTARTISAN AF 27mm is specifically designed for Fuji X mount cameras, making it a perfect fit for owners of that camera brand. On the other hand, the YONGNUO YN50mm is compatible with Canon EF mount cameras, which may appeal to a broader audience due to the popularity of Canon cameras. Photographers should consider their existing camera systems when deciding which lens will serve them best, as compatibility can affect the overall usability of the lens.

Target Audience

The target audience for these lenses varies significantly based on their features and pricing. The TTARTISAN AF 27mm is likely aimed at more experienced photographers who value advanced features and are willing to invest in a higher-quality lens for specific shooting scenarios, such as travel or street photography. In contrast, the YONGNUO YN50mm is well-suited for beginners or casual photographers looking for a budget-friendly lens that still offers good performance for everyday shooting. Each lens has its unique appeal, catering to different segments of the photography market.

Which should you buy?

Ultimately, the choice between the TTARTISAN AF 27mm f2.8 and the YONGNUO YN50mm F1.8 hinges on your specific needs and budget. If you're looking for a portable lens with advanced focusing capabilities and are willing to spend a bit more, the TTARTISAN is a compelling option. However, if you're budget-conscious and seek a versatile lens that excels in low-light conditions, the YONGNUO could be the better fit. Both lenses offer unique advantages, making it essential to weigh your personal photography style and requirements before making a decision.
