The VILTROX AF 28mm F4.5 XF Pancake Lens for Fuji X Mount is a compact and lightweight lens retailing at $99.00. Its unique 28mm focal length provides a wide-angle perspective that is perfect for both on-the-go shooting and vlogging. Weighing only 60g and measuring just 15.3mm in thickness, this lens is designed for portability and convenience. It boasts exceptional image quality through its six-element construction, which includes two ED and two aspherical lenses, ensuring sharp images and vibrant colors.

Autofocus Capabilities

When it comes to autofocus, both lenses are equipped with advanced technologies, but they excel in different areas. The VILTROX 15mm F1.7 features an STM motor that provides precise and fast autofocus, making it ideal for portrait and action photography. This lens is particularly beneficial for those who frequently shoot moving subjects, as it can quickly lock onto focus. In contrast, the VILTROX AF 28mm F4.5 employs a built-in VCM motor, which supports face and eye recognition for effortless shooting. While both lenses offer efficient autofocus, the VILTROX 15mm F1.7 is more suited for dynamic environments, whereas the 28mm lens focuses on ease of use in various shooting scenarios.

Design and Build Quality

The VILTROX 15mm F1.7 has a robust design that caters to serious photographers. Its larger size compared to the pancake lens allows for a more substantial grip, which can be advantageous when using it for extended periods. However, it does come with additional weight and bulk. On the other hand, the VILTROX AF 28mm F4.5 stands out for its ultra-light and slim profile, making it the lightest and thinnest lens in the Viltrox lineup. Its innovative slide cap design adds a layer of protection against dust and dirt while also enhancing the user experience. For those prioritizing portability, the 28mm lens is the clear winner.

Image Quality

Image quality is a critical aspect of any lens, and both lenses deliver impressive results. The VILTROX 15mm F1.7, with its nine aperture blades, offers a dreamy background blur conducive to artistic photography. It also allows for creative perspectives with its closest focusing distance of 0.23m. In contrast, the VILTROX AF 28mm F4.5 features a design with six elements in six groups, ensuring sharp images and vibrant colors. Its unique front element creates beautiful starburst effects, making it particularly appealing for landscape and architectural photography. While both lenses provide high-quality images, the choice may come down to the type of photography you intend to pursue.

Versatility in Use Cases

In terms of versatility, the VILTROX 15mm F1.7 excels in landscape, architecture, and indoor shooting scenarios. Its wide angle of view and large aperture make it a versatile choice for various types of photography, including vlogging. Conversely, the VILTROX AF 28mm F4.5 is designed for on-the-go shooting, making it an excellent option for travel and casual photography. Its compact design allows for easy carrying, while its autofocus capabilities ensure that you can capture spontaneous moments effortlessly. Depending on your photography style, one lens may be more advantageous than the other.

Price Comparison

The price difference between the two lenses is significant, with the VILTROX AF 28mm F4.5 being about 59% cheaper at $99.00 compared to the VILTROX 15mm F1.7, which costs $239.00. This substantial price gap makes the pancake lens a more accessible option for beginners or those on a budget. However, the higher price of the 15mm lens can be justified by its specialized features and capabilities, especially for professionals who require a high-performance lens for specific photography needs.

Which should you buy?

Choosing between the VILTROX 15mm F1.7 E-Mount Lens for Sony and the VILTROX AF 28mm F4.5 XF Pancake Lens for Fuji ultimately depends on your specific needs as a photographer. If you prioritize a wide angle of view and advanced autofocus capabilities for dynamic shooting, the 15mm F1.7 is your best bet. However, if you're looking for portability and a budget-friendly option that doesn’t compromise on image quality, the 28mm F4.5 is a strong contender. Assess your photography style and budget to make the best choice for your needs.
