Both lenses are designed for Nikon cameras, but they cater to different photography needs and styles. The Nikon lens is a prime lens aimed at providing high-quality images with a versatile focal length, while the YONGNUO lens offers a standard focal length with a large aperture that is ideal for portrait photography.
Design and Build Quality
The Nikon AF-S DX NIKKOR 35mm f/1.8G features a compact and lightweight construction, making it an excellent option for photographers who prioritize portability. It includes a rubber seal to minimize moisture ingress, ensuring durability during outdoor shooting. Conversely, the YONGNUO YN50mm 50mm f/1.8 Lens also emphasizes a lightweight design, weighing only about 203 grams, which enhances its travel-friendly nature. Both lenses boast a sturdy build, but the Nikon's moisture resistance offers an edge for outdoor photography.
Optical Performance
The Nikon lens is engineered with an optical design that allows for high reproduction capability and picture quality, featuring an aspherical lens element that minimizes aberrations. It has two focus modes, including a manual override, which adds versatility in different shooting scenarios. On the other hand, the YONGNUO lens employs a high-definition nano-coating that helps reduce light loss and suppresses glare and ghosting. This results in crisp, clear images, making both lenses suitable for different photographic styles and conditions.
Aperture and Low-Light Performance
When it comes to aperture, both lenses excel in low-light conditions. The Nikon AF-S DX NIKKOR 35mm f/1.8G has an aperture range of f/1.8 to f/22, allowing for impressive depth of field control and low-light performance. The YONGNUO YN50mm 50mm f/1.8 Lens, with its wide f/1.8 aperture, is particularly praised for creating a creamy background blur, making it ideal for portrait photography. The design of both lenses ensures that they can handle low-light environments effectively, but the YONGNUO’s aperture is highly favorable for achieving artistic bokeh effects.
Focal Length and Versatility
The Nikon lens offers a focal length equivalent to 52.5mm on a DX-format camera, making it versatile for various photography styles, including street and landscape photography. The YONGNUO lens, with its 50mm focal length, delivers a perspective that closely resembles the human eye, which is beneficial for authentic street photography and documentary work. Both lenses cater to different shooting needs, with the Nikon being slightly more versatile due to its effective focal range on DX-format cameras.
Autofocus and Focus Control
Autofocus capabilities differ between the two lenses. The Nikon AF-S DX NIKKOR 35mm f/1.8G features a Silent Wave Motor (SWM) that provides fast, accurate, and quiet autofocus, enhancing the shooting experience, especially in sensitive environments. It also supports manual focus override, which allows for greater creative control. The YONGNUO YN50mm 50mm f/1.8 Lens offers automatic and manual focus modes, making it intuitive for users who want to switch between focus types. While both lenses include autofocus features, the Nikon’s SWM provides a more refined experience.
Compatibility
The Nikon AF-S DX NIKKOR 35mm f/1.8G is designed specifically for Nikon DX-format DSLRs, rendering it a great choice for those who shoot with Nikon’s crop sensor cameras. It is also compatible with full-frame cameras in DX crop mode. In contrast, the YONGNUO YN50mm 50mm f/1.8 Lens is compatible with a wide range of Nikon F-mount cameras, including several models like the D3000, D5000, and D80 series. This broad compatibility makes the YONGNUO lens appealing for users with various Nikon bodies.
