Overview of the Products

When comparing the EF 85mm f1.8 Portrait Lens to the YONGNUO YN50mm F1.8N Standard Prime Lens, it’s essential to note that they cater to different user needs and camera systems. The EF 85mm lens is designed specifically for Canon DSLRs, whereas the YONGNUO lens is tailored for Nikon DSLR cameras. This distinction is crucial for potential buyers, as compatibility is a primary factor in lens selection.

The EF 85mm f1.8 Portrait Lens, priced at $77.59, is a manual focus lens, offering significant creative control to photographers. On the other hand, the YONGNUO YN50mm F1.8N, priced at $102.00, supports both auto and manual focus modes, making it more versatile for users who prefer automated settings. The price difference between the two is approximately 31%, with the EF 85mm lens being the more budget-friendly option.

Build Quality and Design

The build quality and design of the lenses reveal their intended use and user experience. The EF 85mm f1.8 Portrait Lens is constructed for full manual operation, which may appeal to photographers seeking a tactile connection to their craft. Its design features a smooth large focus ring and incorporates advanced optical technologies for superb image quality.

Conversely, the YONGNUO YN50mm F1.8N lens highlights convenience and ease of use, featuring gold-plated metal contacts for improved signal conductivity and corrosion resistance. This design element enhances durability and reliability, particularly in various shooting conditions. The emphasis on both auto and manual focus modes in the YONGNUO lens makes it a practical choice for those who value flexibility in their lens.

Image Quality

In terms of image quality, the EF 85mm f1.8 Portrait Lens boasts exceptional attributes such as six rounded aperture blades and hybrid aspherical lens technology, which work together to reduce aberrations and glare. This results in clear images with beautiful bokeh effects, making it an excellent option for portraiture where background aesthetics are crucial.

The YONGNUO YN50mm F1.8N lens also aims to deliver high-quality images, particularly as a standard prime lens. It supports full-frame and APS-C formats, which broadens its usability across different camera systems. However, while it provides decent image quality, the EF 85mm lens is often favored for its superior optical performance, especially in low-light conditions and when creating a soft background blur.

Focus Mechanism

The focus mechanism is a critical aspect that differentiates the two lenses. The EF 85mm f1.8 Portrait Lens is entirely manual focus, which means photographers must rely on their skills to achieve the desired focus. This can be seen as a drawback for some, but for others, it offers a chance to refine their focusing techniques and engage more deeply with the photographic process.

In contrast, the YONGNUO YN50mm F1.8N offers both autofocus and manual focus capabilities, allowing users to switch between modes based on their shooting preferences. This flexibility can be particularly beneficial in fast-paced environments or when capturing spontaneous moments, making the YONGNUO lens more user-friendly for a broader range of photography styles.

Compatibility

Compatibility is a vital consideration when choosing a lens. The EF 85mm f1.8 Portrait Lens is exclusively compatible with Canon DSLRs, including a wide range of models such as the EOS Rebel series and the 5D Mark IV. This extensive compatibility ensures that many Canon users can take advantage of this lens.

On the other hand, the YONGNUO YN50mm F1.8N is designed for Nikon DSLR cameras, supporting both full-frame and APS-C formats. This allows it to serve a diverse audience of Nikon users. However, users must ensure their specific camera model is compatible with the YONGNUO lens, as it may not fit all Nikon models.

Price Comparison

Price is a significant factor in any product comparison, and here, the EF 85mm f1.8 Portrait Lens stands out as the more economical choice, priced at $77.59. This makes it about 31% cheaper than the YONGNUO YN50mm F1.8N, which retails for $102.00. For budget-conscious photographers, this price difference can be a deciding factor.

Although the YONGNUO lens is more expensive, it offers features like autofocus, which might justify the higher cost for users who prefer that functionality. Ultimately, the choice between these lenses may hinge on whether the user values manual focus control or the convenience of autofocus.

Target Audience

Each lens targets distinct groups of photographers. The EF 85mm f1.8 Portrait Lens appeals primarily to manual shooters and portrait photographers who appreciate the artistry of manual focus. Its specifications cater to those who want to hone their skills and create stunning portraiture with a beautiful bokeh effect.

The YONGNUO YN50mm F1.8N, with its dual focus options, is tailored for a wider audience, including beginners and those who prefer a mix of automation and manual control. Its versatility in supporting different shooting modes makes it suitable for everyday photography, from portraits to street photography.

Which should you buy?

The decision between the EF 85mm f1.8 Portrait Lens and the YONGNUO YN50mm F1.8N ultimately depends on your camera system and photographic preferences. If you are a Canon user looking for a budget-friendly lens that offers manual focus control and exceptional image quality, the EF 85mm is an excellent choice. However, if you are a Nikon user who values versatility with options for both autofocus and manual focus, the YONGNUO lens might better meet your needs. Each lens has its strengths, and the right choice hinges on your specific requirements and shooting style.
