Overview of the TTARTISAN AF 27mm f2.8 and YONGNUO YN50mm F1.8N

The TTARTISAN AF 27mm f2.8 is a pancake lens designed for Fuji X mount cameras, while the YONGNUO YN50mm F1.8N is a standard prime lens compatible with Nikon DSLR cameras. Both lenses serve distinct purposes in photography, catering to different camera systems and user preferences. The TTARTISAN lens is priced at $159.99, making it about 57% more expensive than the YONGNUO lens, which retails for $102.00.

Design and Portability

The TTARTISAN AF 27mm f2.8 lens stands out for its ultra-compact pancake design, which makes it highly portable and convenient for travel photography. Its lightweight nature means that photographers can easily carry it without adding significant weight to their gear. In contrast, the YONGNUO YN50mm F1.8N, while still lightweight, is bulkier than the pancake design, making it slightly less convenient for on-the-go shooting. The compactness of the TTARTISAN lens can be particularly appealing for those who prioritize mobility in their photography.

Focus Mechanism

The TTARTISAN AF 27mm f2.8 features an STM (Stepping Motor) focus mechanism, which provides smooth and quiet autofocus performance. This is particularly beneficial for videographers who require minimal noise during recording. The YONGNUO YN50mm F1.8N supports both auto and manual focus modes, offering flexibility for various shooting situations. However, it does not specify a similar advanced focusing system as the TTARTISAN lens. For users looking for a lens with efficient and silent focusing, the TTARTISAN may be the more suitable choice.

Aperture and Low Light Performance

With a maximum aperture of f2.8, the TTARTISAN AF 27mm is less capable in low-light conditions compared to the YONGNUO YN50mm F1.8N, which has a larger f1.8 aperture. This means that the YN50mm can gather more light, allowing for better performance in dim environments and providing a shallower depth of field for more pronounced background blur. Photographers focused on achieving bokeh or shooting in low light may find the YONGNUO lens more appealing due to its wider aperture.

Compatibility and Versatility

The TTARTISAN AF 27mm f2.8 is designed specifically for Fuji X mount cameras, such as the Fujifilm XS10, X-E4, and others in the Fuji lineup. This specialization allows the lens to maximize compatibility and performance with these specific models. On the other hand, the YONGNUO YN50mm F1.8N supports both full-frame and APS-C format cameras, making it a versatile option for Nikon users. The broader compatibility of the YONGNUO lens might be attractive to photographers who own multiple Nikon cameras or are considering future upgrades.

Unique Features

One of the standout features of the TTARTISAN AF 27mm f2.8 is its independent clicked aperture ring, which provides photographers with quick and convenient control over exposure settings. Additionally, it includes a USB-C interface for firmware upgrades, enhancing the lens's performance over time. The YONGNUO YN50mm F1.8N, while lacking similar advanced features, boasts gold-plated metal contacts that improve signal conductivity and corrosion resistance, ensuring reliable performance. Users may find the added functionality of the TTARTISAN lens beneficial for their creative needs.

Pricing and Value

The TTARTISAN AF 27mm f2.8 is priced at $159.99, while the YONGNUO YN50mm F1.8N is available for $102.00. This price difference of about $57.99 makes the YONGNUO lens approximately 36% cheaper than the TTARTISAN. For photographers on a budget, the YONGNUO lens presents a more economical option without sacrificing essential features. However, those willing to invest more may appreciate the unique advantages offered by the TTARTISAN lens.

Which should you buy?

Choosing between the TTARTISAN AF 27mm f2.8 and the YONGNUO YN50mm F1.8N ultimately depends on your specific needs as a photographer. If you prioritize portability, advanced focusing technology, and unique features like firmware upgrades, the TTARTISAN lens could be the better choice. However, if you are looking for a more versatile lens with superior low-light performance at a lower price, the YONGNUO lens is likely the more suitable option. Consider your camera system and shooting style to make the best decision for your photography needs.
