Overview of the TTARTISAN AF 27mm f2.8 and YONGNUO YN50mm F1.8C
The TTARTISAN AF 27mm f2.8 and YONGNUO YN50mm F1.8C serve different niches in the photography landscape. The TTARTISAN lens, priced at $159.99, is an ultra-compact pancake lens designed for Fuji X mount cameras, while the YONGNUO lens is a larger aperture option, retailing at $132.29, tailored for Canon EF mount cameras. This price difference of about 17% indicates the varying markets these lenses cater to.
Design and Portability
When it comes to design, the TTARTISAN AF 27mm f2.8 stands out for its ultra-compact pancake structure, making it incredibly portable and ideal for travel photography. Its sleek design allows photographers to carry it effortlessly, fitting it into small bags or even pockets. In contrast, the YONGNUO YN50mm F1.8C is more traditional in size, measuring 2 inches in length, which, while not excessively bulky, does not offer the same level of portability. If travel is a priority, the TTARTISAN lens is the better choice.
Autofocus Capabilities
Both lenses offer autofocus capabilities, but they do so in different ways. The TTARTISAN AF 27mm utilizes an STM stepping motor for smooth focusing, enhancing the shooting experience, especially in dynamic situations. It also features eye recognition focus for capturing sharp images of subjects. On the other hand, the YONGNUO YN50mm F1.8C supports both autofocus and manual focus, providing versatility for different shooting styles. However, the absence of advanced features like eye tracking may limit its effectiveness in capturing fast-moving subjects.
Aperture and Low Light Performance
The aperture size is crucial for low-light performance, and here the YONGNUO YN50mm F1.8C has a distinct advantage with its maximum aperture of f/1.8. This allows for significantly better performance in dimly lit conditions compared to the TTARTISAN AF 27mm, which has a maximum aperture of f/2.8. The larger aperture of the YONGNUO not only enables faster shutter speeds but also creates a shallower depth of field, enhancing bokeh effects. For photographers who prioritize low-light shooting, the YONGNUO lens emerges as the superior option.
Image Quality and Sharpness
Both lenses aim to deliver high image quality, but their designs cater to different needs. The TTARTISAN AF 27mm f2.8 is designed for portability without compromising on sharpness, making it suitable for everyday photography and travel. In comparison, the YONGNUO YN50mm F1.8C emphasizes edge-to-edge sharpness, making it a great addition for those looking to enhance their EOS 18-55mm lens kits. The YONGNUO's design with six elements in five groups aims for high-quality images, particularly at wider apertures.
Compatibility and Use Cases
Compatibility is another important factor to consider. The TTARTISAN AF 27mm f2.8 is designed specifically for Fuji X mount cameras, such as the Fujifilm XS10 and X-T4, making it a solid choice for users of that ecosystem. Meanwhile, the YONGNUO YN50mm F1.8C is compatible with a wider range of Canon EF cameras, including the 5D series and 70D, making it versatile for Canon users. The choice between these two lenses will largely depend on the camera system you use, as each lens is optimized for different mounts.
Price and Value Proposition
The TTARTISAN AF 27mm f2.8 is priced at $159.99, while the YONGNUO YN50mm F1.8C is available for $132.29. This means the YONGNUO is roughly 17% less expensive, offering a more budget-friendly option for those looking to expand their lens collection without breaking the bank. However, the additional features and compact nature of the TTARTISAN lens may justify its higher price for Fuji users who value portability and advanced focusing technology.
User Experience and Features
The TTARTISAN lens also incorporates a clicked aperture ring, allowing for quicker adjustments during shooting. Additionally, it has a USB-C interface for firmware upgrades, enhancing its lifespan and performance. The YONGNUO lens, while it lacks these specific features, offers a straightforward user experience with its dual focus options. This user-centric design may appeal to photographers who prefer simplicity over advanced functionalities.
Which should you buy?
The decision between the TTARTISAN AF 27mm f2.8 and YONGNUO YN50mm F1.8C largely depends on your photographic needs and the camera system you use. If you prioritize portability, advanced focusing features, and own a Fuji X mount camera, the TTARTISAN lens is an excellent choice. Conversely, if you're a Canon user looking for a versatile, budget-friendly lens that excels in low-light conditions, the YONGNUO lens is likely the better option. Each lens has its strengths, making them suitable for different types of photographers.
