Dimension comparison
Price Comparison
The Viltrox 25mm F1.7 E is priced at $176.00, while the VILTROX AF 50mm F2.0 Air Z Lens is available for $199.00. This makes the 25mm lens about 12% cheaper than the 50mm option. For budget-conscious photographers, the lower price of the 25mm lens could be a deciding factor, especially if they are looking for a reliable lens without breaking the bank. However, the slightly higher price of the 50mm lens might be justifiable for those seeking its specific features and capabilities.
Aperture Performance
The Viltrox 25mm F1.7 E boasts a bright f/1.7 maximum aperture, which is ideal for low-light conditions and allows for greater control over depth of field. In contrast, the VILTROX AF 50mm F2.0 Air Z Lens features a slightly narrower f/2.0 aperture. While both lenses perform well in low-light situations, the 25mm lens gives photographers more flexibility with shallow depth of field effects. This could be particularly appealing for portrait and artistic photography where background blur is essential.
Autofocus Capabilities
Both lenses offer advanced autofocus capabilities, but they utilize different technologies. The Viltrox 25mm F1.7 E employs an STM stepper motor, ensuring a quiet autofocus experience, which is advantageous for video recording. On the other hand, the VILTROX AF 50mm F2.0 Air Z Lens integrates an STM motor combined with a lead screw to achieve precise autofocus and support for eye/face detection. This feature enhances the lens's performance in portrait photography, making it easier to focus on subjects quickly and accurately, especially in dynamic shooting situations.
Design and Weight
The Viltrox 25mm F1.7 E weighs in at a lightweight 170 grams, making it an excellent choice for travel and everyday use. The VILTROX AF 50mm F2.0 Air Z Lens is slightly heavier at 220 grams, which may be a consideration for those who prioritize portability. However, both lenses are designed to be compact and easy to handle, catering to photographers who require mobility without sacrificing performance. The 50mm lens's additional weight may also contribute to its build quality, making it feel more robust in hand.
Compatibility
The Viltrox 25mm F1.7 E is specifically designed for Sony E mount cameras, making it a perfect match for users of models like the ZV-E10 II and A6700. In contrast, the VILTROX AF 50mm F2.0 Air Z Lens is tailored for Nikon Z mount cameras, including the Z6, Z7, and Z9 series. This difference in compatibility is crucial for photographers when selecting a lens, as each product is optimized for its respective camera system, ensuring seamless integration and performance.
Optical Quality
When it comes to optical design, the VILTROX AF 50mm F2.0 Air Z Lens features an advanced structure of 13 elements in 9 groups, which includes 3 ED lenses and 4 high-refractive elements. This design aims to produce vivid, distortion-free images, catering to photographers seeking high-quality results. The Viltrox 25mm F1.7 E, while not detailed in its optical construction, is designed to offer a bright aperture suitable for a range of photographic situations. The superior optical design of the 50mm lens may be more appealing to professionals or enthusiasts focused on achieving the best image quality.
Use Case Versatility
The Viltrox 25mm F1.7 E is versatile, suitable for various shooting scenarios, including portraits, street photography, and even vlogging due to its lightweight and compact design. Its wide aperture also makes it ideal for low-light shooting. The VILTROX AF 50mm F2.0 Air Z Lens, with its standard focal length, excels in portrait photography while also being capable of handling landscapes and everyday documentation. Its larger aperture allows for beautiful bokeh effects, making it a favorite among portrait photographers. Depending on the intended use, each lens serves its purpose well.
Which should you buy?
Choosing between the Viltrox 25mm F1.7 E and the VILTROX AF 50mm F2.0 Air Z Lens ultimately depends on your specific needs and camera compatibility. If you're using a Sony E mount camera and prioritize a lightweight design with a brighter aperture for low-light conditions, the 25mm lens may be the better choice, especially given its lower price of $176.00. Conversely, if you're a Nikon Z mount user seeking exceptional optical quality and versatile performance for portraits and everyday photography, the 50mm lens, priced at $199.00, could be worth the investment. Each lens offers unique features tailored to different shooting styles, making the decision highly personal.
