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.
