When comparing the TTArtisan 40mm F2 L and the YONGNUO YN50mm F1.8C, photographers can find two distinct lenses each tailored for specific needs. The TTArtisan 40mm F2 L is designed for L mount system cameras, offering a versatile focal length ideal for various shooting conditions. Conversely, the YONGNUO YN50mm F1.8C caters specifically to Canon EF mount cameras, excelling in low-light scenarios due to its larger aperture.

Price Comparison

The YONGNUO YN50mm F1.8C is priced at $132.29, making it about 21% cheaper than the TTArtisan 40mm F2 L, which retails for $168.00. The significant price difference may appeal to budget-conscious photographers looking for a quality lens without breaking the bank. Additionally, the YONGNUO lens has shown a lower average price over the last 90 days at $82.40, indicating that it might offer even better value with time. On the other hand, the TTArtisan lens maintains a stable price around $165.86, suggesting consistent demand.

Build Quality and Design

In terms of build quality, both lenses are compact and lightweight, making them easy to carry for extended shoots. The TTArtisan 40mm F2 L weighs between 167-176g, allowing for flexibility in shooting angles without compromising on balance. This lens incorporates advanced optical elements, including ED and aspherical components, to control chromatic aberration and enhance clarity significantly. The YONGNUO YN50mm F1.8C, while also compact at 2 inches in length, is built specifically for Canon EF mount cameras and is designed to be an excellent addition to existing lens kits, particularly for those who may already own the Canon 18-55mm lens.

Aperture and Low-Light Performance

The YONGNUO YN50mm F1.8C boasts a maximum aperture of F1.8, which enables it to perform exceptionally well in low-light situations. This large aperture allows for faster shutter speeds, making it ideal for capturing sharp images in dimly lit environments. In contrast, the TTArtisan 40mm F2 L, while also effective in low light, has a slightly smaller maximum aperture. Its F2.0 aperture still allows for good low-light performance, but it may not match the YONGNUO's capabilities in challenging lighting conditions.

Autofocus Capabilities

Both lenses offer autofocus capabilities, but they employ different technologies. The TTArtisan 40mm F2 L features a quiet and fast autofocus system powered by an STM stepping motor, which ensures quick and precise focusing, particularly beneficial for street or travel photography. Meanwhile, the YONGNUO YN50mm F1.8C also supports both autofocus and manual focus, allowing photographers the flexibility to switch modes as needed. This dual functionality can be particularly advantageous in various shooting scenarios, enabling creative control over the focus.

Versatility and Use Cases

The versatility of the TTArtisan 40mm F2 L is highlighted by its focal length, which is ideal for street, travel, documentary, and everyday photography. It balances the environmental context with subject isolation, making it a favored choice for photographers who require adaptability in their lens choices. The YONGNUO YN50mm F1.8C, with its 50mm focal length, is also versatile, but it especially shines in portrait photography due to its ability to create beautiful background blur and sharp subject focus. However, its use is primarily limited to Canon EF mount cameras, which could restrict options for photographers using other systems.

Image Quality

Image quality is paramount for any lens, and both the TTArtisan 40mm F2 L and the YONGNUO YN50mm F1.8C deliver remarkable results. The TTArtisan lens combines advanced optical elements to control chromatic aberration while maintaining clarity, ensuring sharp images across various scenarios. On the other hand, the YONGNUO lens provides excellent edge-to-edge sharpness, making it a solid choice for capturing detailed images. Photographers may find that the choice between the two could come down to personal preferences in image rendering and the specific photographic context they are working within.

Which should you buy?

Ultimately, the decision between the TTArtisan 40mm F2 L and the YONGNUO YN50mm F1.8C hinges on your camera system and photography style. If you use an L mount camera and seek a versatile lens for various shooting conditions, the TTArtisan 40mm F2 L is an excellent choice, albeit at a higher price point. Conversely, if you are a Canon EF mount user looking for an affordable lens that excels in low-light situations and offers both autofocus and manual focus capabilities, the YONGNUO YN50mm F1.8C presents a compelling option. Each lens has its strengths, and understanding your specific needs will guide you to the right choice.
