Image Quality Comparison
When it comes to image quality, the VILTROX 56mm F1.7 excels in low-light situations thanks to its larger aperture. The f/1.7 aperture allows for greater light intake, resulting in brighter images and enhanced performance in challenging lighting conditions. The nine-blade diaphragm supports beautiful bokeh, making it ideal for portrait work.
In contrast, the VILTROX AF 28mm F4.5 focuses on delivering vibrant colors and sharp images, which is enhanced by its unique front element that creates starburst effects. While it may not perform as well in low-light conditions as the 56mm F1.7, its innovative design and optical elements ensure good image quality, particularly in well-lit environments.
Autofocus Performance
Autofocus performance is a notable aspect of both lenses. The VILTROX 56mm F1.7 utilizes an STM stepper motor for quiet and smooth autofocus, making it suitable for both photo and video applications where noise reduction is crucial. This feature is particularly beneficial for portrait photography, where capturing the moment without distractions is essential.
On the other hand, the VILTROX AF 28mm F4.5 benefits from a built-in VCM motor that supports fast and efficient autofocus, including face and eye recognition capabilities. This lens is designed for quick setup and ease of use, making it an excellent choice for vlogging and spontaneous shooting.

Weight and Portability
Portability is a significant factor for photographers who frequently travel.

The pancake design of the 28mm lens makes it the thinnest and lightest in the Viltrox lineup, measuring just 15.3mm in thickness.
For photographers who prioritize minimal gear and easy handling, the AF 28mm offers unparalleled convenience, making it easy to carry around for extended periods. In contrast, while the 56mm is still manageable, it may not fit as effortlessly into a compact camera bag.
Versatility and Use Cases
The VILTROX 56mm F1.7 is primarily suited for portrait photography, providing the depth of field necessary for flattering subject isolation. Its ability to perform well in low-light environments makes it versatile for various settings, from indoor portraits to evening events.
Conversely, the VILTROX AF 28mm F4.5 is more versatile in terms of shooting styles, excelling in landscape, street photography, and vlogging due to its wide-angle perspective. The lens's lightweight and slim design allows for easy handling during extended shoots, making it a preferred choice for users who want to capture a wide range of scenes without changing lenses frequently.
Price and Value
In terms of pricing, the VILTROX AF 28mm F4.5 is significantly more affordable at $99.00, compared to the VILTROX 56mm F1.7, which retails at $180.00. This price difference of about $81 means that the 28mm lens is approximately 45% cheaper, offering great value for photographers on a budget or those just starting out.
While the 56mm provides advanced features and higher performance in specific areas like low-light photography and bokeh quality, the cost may be a consideration for many buyers. The AF 28mm, being more accessible, can serve as an excellent addition to a photographer's kit without breaking the bank.
Which should you buy?
Choosing between the VILTROX 56mm F1.7 and the VILTROX AF 28mm F4.5 ultimately depends on your specific photography needs.
