Both lenses are designed for different camera mounts—TTARTISAN for Nikon Z-mount cameras and YONGNUO for Canon EF-mount cameras—catering to different user bases. Each lens brings unique advantages tailored to specific photography styles, particularly focusing on low-light performance and depth of field effects.
Build Quality and Portability
The TTARTISAN 40mm f2 Lens is constructed from premium 5052 aerospace aluminum, weighing only 167 grams. This ultra-portable design makes it easy to carry on photography adventures without compromising on durability. In contrast, while specific materials for the YONGNUO YN50mm F1.8 Lens are not detailed, it is a larger lens designed for versatility. Although it supports both auto and manual focus, it may not match the TTARTISAN in terms of lightweight portability, especially for photographers who prioritize minimalism in their gear.
Lens Performance in Low Light
The TTARTISAN 40mm f2 Lens excels in low-light conditions with its f/2 aperture, allowing for stunning clarity and vibrant color reproduction even in dim environments. This makes it an excellent choice for night photography or indoor shoots. Meanwhile, the YONGNUO YN50mm F1.8 Lens, with a larger f/1.8 aperture, also offers considerable low-light capability, providing a distinct advantage for creating soft backgrounds and bokeh effects in portraits. The difference in aperture size indicates that the YONGNUO lens could capture slightly more light, making it potentially superior for low-light scenarios.
Focus Capabilities
Focusing performance is crucial for any lens, and both the TTARTISAN and YONGNUO lenses offer unique features. The TTARTISAN 40mm f2 Lens features an advanced autofocus system with an STM motor and face/eye tracking, ensuring smooth focus transitions with minimal breathing. This is particularly beneficial for videographers and portrait photographers. Conversely, the YONGNUO YN50mm F1.8 Lens supports both auto and manual focus modes and includes a focus distance indicator, making it user-friendly for those who want to measure shooting distance and depth of field accurately.
Versatility in Usage
The TTARTISAN 40mm f2 Lens is designed primarily for full-frame E-mount cameras, providing a true-to-life perspective with a 57° full-frame angle. It’s particularly suitable for capturing authentic textures and human-eye vision. On the other hand, the YONGNUO YN50mm F1.8 Lens is compatible with both full-frame and APS-C format cameras, enhancing its versatility across different camera systems. This broader compatibility may appeal to photographers who own multiple camera types, allowing for greater flexibility in lens usage.
Price Comparison
The price difference between the TTARTISAN 40mm f2 Lens and the YONGNUO YN50mm F1.8 Lens is significant, with the YONGNUO lens available for $82.00, making it about 51% cheaper than the TTARTISAN lens at $168.00. This substantial cost advantage makes the YONGNUO an appealing option for budget-conscious photographers. However, the price difference may reflect the build quality and advanced features offered by the TTARTISAN, which could justify the higher investment for serious enthusiasts or professionals.
User Experience and Feedback
Both lenses cater to different types of photographers, which may influence user satisfaction. The TTARTISAN 40mm f2 Lens offers tactile feedback with its click-stop aperture ring for quick adjustments, enhancing the user experience during shoots. The YONGNUO YN50mm F1.8 Lens, with its focus distance indicator and multi-coated lenses, aims to provide a seamless shooting experience, especially for those who appreciate detailed control over their focus settings. The choice between these lenses may boil down to personal preferences regarding handling and user interface.
Which should you buy?

If you prioritize build quality, low-light performance, and advanced autofocus features, the TTARTISAN may be worth the higher price. However, if you're looking for a budget-friendly option that still delivers excellent performance, particularly in low-light settings, the YONGNUO lens stands out as a compelling choice. Each lens has its strengths, making them suitable for different photography styles and preferences.
