VILTROX AF vs VILTROX

Design and build quality

The VILTROX AF 35mm f/1.7 emphasizes portability with a compact metal body weighing only 170g. This makes it highly suitable for photographers who prioritize mobility and street photography where discretion is key. The VILTROX AF 50mm f/2.0 Z is slightly heavier at 220g but maintains a compact form factor. Both lenses feature durable construction, though the 50mm model provides specific details regarding filter threading that the 35mm model lacks in the provided data. The build quality suggests long-lasting performance for both options.

Optical Construction

Optical design differs between the two lenses. The 35mm model utilizes 11 elements in 9 groups, including High Refractive, Extra-low Dispersion, and Aspherical elements to minimize aberrations. The 50mm model advances this with 13 elements in 9 groups, incorporating 3 ED lenses, 4 high-refractive elements, and 1 aspherical element. Additionally, the 50mm lens features HD nano-coating. This suggests the 50mm option may offer slightly better control over distortion and flare based on the element count and coating specifications provided.

Autofocus Performance

Both lenses employ STM motors to drive autofocus mechanisms. The 35mm lens is described as having a new STM motor for fast autofocus and low focus breathing. The 50mm lens uses an STM motor combined with a lead screw to achieve autofocus. While both aim for efficiency and reliability, the specific mention of low focus breathing on the 35mm model is beneficial for video work. However, the 50mm model emphasizes efficient and reliable operation suitable for various photography styles.

Aperture and Light Gathering

The maximum aperture is a key differentiator. The 35mm lens offers a bright f/1.7 aperture, allowing for exceptional low-light performance and background blur. The 50mm lens features an f/2.0 aperture with a range up to F16. The 50mm model specifies 9 aperture blades, which contributes to a dreamy and artistic bokeh effect. While the 35mm is faster by one-third of a stop, the 50mm provides detailed information on blade count which influences the quality of out-of-focus areas.

Focal Length and Perspective

Focal length dictates the field of view. The 35mm lens offers a wider perspective, often compared to the human eye, suitable for landscapes and street photography. The text contains a discrepancy mentioning 53mm in one section but identifies as a 35mm lens primarily. The 50mm lens provides a standard perspective, ideal for portraits and everyday documentation. The 50mm focal length presents a natural and authentic image, effectively highlighting the subject by blurring distracting backgrounds without the wider distortion of the 35mm option.

Close Focus Capabilities

Minimum focusing distance determines macro capabilities. The 50mm lens specifies a minimum focusing distance of 0.51m with a magnification of 0.11X. This allows for detailed close-up shots within its limits. The 35mm lens data does not explicitly state the minimum focusing distance or magnification ratio. For photographers requiring known close-focus specifications for product or detail work, the 50mm model offers clearer data regarding its near-focus performance limits.

Price and value

Cost is a significant factor for buyers. The 35mm lens is priced at $179.00, making it the more affordable option. The 50mm lens is listed at $199.00. The $20 difference reflects the additional optical elements and specified features of the 50mm model. For budget-conscious users, the 35mm provides a lower entry point with a faster aperture. However, the 50mm justifies the higher cost with more complex optical engineering and defined compatibility with Nikon Z mounts.

Which one should you buy?

Choose the VILTROX AF 35mm f/1.7 if you need a lighter lens with a faster aperture for low-light situations and street photography at a lower price. Select the VILTROX AF 50mm f/2.0 Z if you require Nikon Z mount compatibility, more optical elements for image correction, and specified close-focus distances. The 50mm model wins on optical complexity and specification clarity, while the 35mm wins on portability and light gathering speed.
