Overview of the Lenses
When comparing the EF 85mm f1.8 Portrait Lens and the YONGNUO YN50mm 50mm f/1.8 Lens, it's essential to note that both lenses cater to different photography needs. The EF 85mm f1.8 is tailored for Canon cameras, while the YONGNUO 50mm is designed for Nikon users. Priced at $77.59, the EF 85mm lens is about 24% cheaper than the YONGNUO 50mm, which retails for $102.00. This price difference could be a significant factor for photographers on a budget.
Build Quality and Design
The build quality of both lenses reflects their intended use. The EF 85mm f1.8 features a fully manual focus design that emphasizes precision and control, essential for portrait photography. Its internal focus mechanism ensures stability during shooting, allowing photographers to experiment creatively. On the other hand, the YONGNUO YN50mm boasts a compact design, weighing just 203 grams, making it highly portable. The use of high-precision metal bayonet and gold-plated contacts enhances its durability, ensuring it withstands the rigors of daily use.
Focusing Mechanism
Focusing is a critical aspect where these two lenses diverge significantly. The EF 85mm f1.8 is a manual focus lens, which can be a double-edged sword. While it offers precise control over focus, it requires the photographer to switch the camera to full manual mode, which might be challenging for beginners. In contrast, the YONGNUO YN50mm provides both automatic and manual focus options, allowing for intuitive control over depth of field and exposure. This flexibility can be particularly beneficial for users who frequently switch between different shooting scenarios.
Image Quality
Image quality is paramount for any lens, and both products deliver commendably in this regard. The EF 85mm f1.8 includes a hybrid aspherical lens design and ultra multi-coating technology that significantly reduces aberrations and glare, leading to stunningly clear images with beautiful bokeh effects. Meanwhile, the YONGNUO YN50mm features a 7-blade circular aperture that produces a creamy background blur, ideal for portraits and low-light shooting. The optical structure of the YN50mm also employs high-definition nano-coating to minimize light loss, ensuring sharp, distortion-free images.
Compatibility
Compatibility is a crucial factor when choosing a lens. The EF 85mm f1.8 is specifically designed for a wide range of Canon DSLR cameras, including popular models like the EOS Rebel series and the 5D Mark IV. This broad compatibility makes it a versatile choice for Canon users. In contrast, the YONGNUO YN50mm is tailored for Nikon F-mount cameras, compatible with numerous models from the D3000 series to the D800 series. This ensures that both lenses can be used effectively across their respective camera brands without any compatibility issues.
Performance in Low Light
When it comes to low-light performance, both lenses shine but in different ways. The EF 85mm f1.8, with its f/1.8 aperture, is excellent for capturing detailed portraits in dim lighting, allowing for faster shutter speeds without sacrificing image quality. This makes it a reliable choice for evening events or indoor settings. Meanwhile, the YONGNUO YN50mm also excels in low-light conditions, thanks to its large aperture. Its ability to create stunning low-light portraits with minimal noise makes it ideal for wedding photography or artistic storytelling.
Price Comparison
Pricing plays a significant role in the decision-making process for many photographers. The EF 85mm f1.8 is currently priced at $77.59, making it an attractive option for those seeking quality without breaking the bank. In contrast, the YONGNUO YN50mm is priced at $102.00, which is approximately $24.41 more expensive. For budget-conscious photographers, the lower price of the EF 85mm may offer a compelling reason to choose it over the YONGNUO lens.
Which should you buy?
Ultimately, the decision between the EF 85mm f1.8 Portrait Lens and the YONGNUO YN50mm 50mm f/1.8 Lens boils down to your camera system and specific photography needs. If you own a Canon camera and prefer a lens that excels in portraiture with a focus on creative control, the EF 85mm is a solid choice, especially at its lower price point. On the other hand, if you are a Nikon user seeking a versatile, lightweight option with both automatic and manual focus capabilities, the YONGNUO YN50mm is worth considering. Each lens has its strengths, so your choice should align with your photographic style and brand compatibility.
