Overview of the EF 85mm f1.8 Portrait Lens and YONGNUO YN50mm F1.8 Lens

The EF 85mm f1.8 Portrait Lens is priced at $77.59, making it about 17% cheaper than the YONGNUO YN50mm F1.8 Lens, which retails for $82.00. Both lenses cater to Canon DSLR users but offer distinct features and focusing mechanisms that set them apart. The EF 85mm lens is a fully manual focus lens, providing a hands-on experience for photographers who appreciate precision. In contrast, the YONGNUO lens supports both auto and manual focus modes, appealing to a broader audience, particularly those who prefer the ease of autofocus.

Focusing Mechanism

The EF 85mm f1.8 Portrait Lens operates entirely in manual focus mode, allowing photographers to gain complete control over focus adjustments. This can lead to a more immersive shooting experience as users must consider shutter speed, ISO, and aperture settings manually. On the other hand, the YONGNUO YN50mm F1.8 Lens features an auto focus capability, which can be beneficial for those who want quick and efficient focusing. While the manual focus of the EF lens can enhance skill development, the dual-focus option of the YONGNUO lens provides versatility and convenience for various shooting situations.

Image Quality and Aperture

The EF 85mm f1.8 Portrait Lens boasts a maximum aperture of f1.8 and incorporates advanced optical technology, including hybrid aspherical lenses and ultra multi-coating. This combination effectively reduces aberrations and glare, resulting in exceptional image clarity and pleasing bokeh. The YONGNUO YN50mm F1.8 Lens also features a large f1.8 aperture, which allows for similar creative depth of field effects. However, it lacks the same level of specialized optical engineering found in the EF lens. Consequently, while both lenses can deliver quality images, the EF lens may have an edge in producing more artistically pleasing results.

Build Quality and Design

The EF 85mm f1.8 Portrait Lens is designed for durability and stability, emphasizing a robust build that can withstand regular use. Its manual focus mechanism encourages photographers to engage deeply with their craft, but this also means the lens is devoid of electronic contacts, which can affect compatibility with certain camera settings. Conversely, the YONGNUO YN50mm F1.8 Lens is designed with practicality in mind, featuring metal contacts for improved signal conductivity and resistance to corrosion. This design choice makes it a suitable option for users who want a reliable lens that integrates seamlessly with various Canon camera modes.

Compatibility

The EF 85mm f1.8 Portrait Lens is compatible with a wide range of Canon DSLRs, including models such as the EOS Rebel T8i, T7i, and 5D Mark IV. This extensive compatibility ensures that many photographers can use it with their existing gear. The YONGNUO YN50mm F1.8 Lens also supports a variety of Canon EF mount cameras, including both full-frame and APS-C format models. This broad compatibility is beneficial for photographers who may switch between different camera types but prefer a lens that can adapt across their systems.

Price Comparison

At $77.59, the EF 85mm f1.8 Portrait Lens provides a cost-effective option for photographers looking for a quality portrait lens. In comparison, the YONGNUO YN50mm F1.8 Lens is priced at $82.00, putting it at a 5.5% higher price point. Given the manual focus nature of the EF lens, the lower price can be particularly appealing to those who prioritize affordability without sacrificing quality. However, the added convenience of autofocus found in the YONGNUO lens may justify its higher price for some users.

After-Sales Support

The EF 85mm f1.8 Portrait Lens comes with professional after-sales support, including maintenance and replacement services during the warranty period. This can provide peace of mind for users concerned about potential issues or repairs. While specific after-sales information for the YONGNUO YN50mm F1.8 Lens is not detailed, having a reputable brand can often translate to satisfactory customer service experiences. Thus, knowing the level of support available can influence a buyer's decision as they consider long-term usability.

Which should you buy?

Choosing between the EF 85mm f1.8 Portrait Lens and the YONGNUO YN50mm F1.8 Lens ultimately hinges on your photographic needs and preferences. If you value manual control and are looking for a more budget-friendly option, the EF 85mm lens is the ideal choice, priced at $77.59. On the other hand, if you prefer the flexibility of autofocus and a slightly higher price point, the YONGNUO lens at $82.00 may be more suitable for you. Both lenses have their own strengths, and your choice will depend on the specific style of photography you wish to pursue.
