This significant price difference sets the stage for a closer examination of their features, performance, and suitability for various photography needs.
Design and Build Quality
The Canon RF45mm F1.2 STM boasts a robust design that reflects its premium positioning in the market. It has a standard prime lens structure with a large-diameter mount that contributes to its compactness. In contrast, the VILTROX 28mm F4.5 is noted for its ultra-thin and lightweight design, measuring just 15.3mm in thickness and weighing only 60g. This makes the VILTROX lens extremely portable, ideal for photographers who prioritize convenience. Despite the differences in size, both lenses are designed to withstand the rigors of daily use, with the VILTROX featuring a durable metal barrel.
Optical Performance
The Canon RF45mm F1.2 STM lens is engineered for exceptional optical performance, particularly in low-light conditions, thanks to its wide f/1.2 aperture. This allows for faster shutter speeds and creates beautiful bokeh effects, isolating subjects effectively from the background. On the other hand, the VILTROX 28mm F4.5, while not as fast, offers a versatile wide-angle perspective that is favored by street photographers. The multi-layer coating on the VILTROX lens minimizes light interference, ensuring sharp and clear images. For those who appreciate depth in their images, the Canon lens undoubtedly has the edge.
Focal Length and Versatility
The Canon RF45mm F1.2 STM features a focal length of 45mm, making it a great option for portraits and lifestyle photography. This standard focal length is versatile but leans more towards subjects that require depth and isolation. Conversely, the VILTROX 28mm F4.5 offers a wider focal length suited for capturing expansive scenes, street photography, and environmental portraits. This difference in focal length significantly impacts the lenses' applications, making the Canon lens more specialized for portrait work while the VILTROX excels in versatile shooting environments.

Autofocus performance is crucial for many photographers, and both lenses offer distinct advantages. The Canon RF45mm F1.2 STM features a state-of-the-art autofocus system that allows for quick and precise focusing, enhancing the user experience for fast-paced shooting scenarios. Meanwhile, the VILTROX 28mm F4.5 is designed with an efficient autofocus system that maintains precision and agility, making it user-friendly for those who prefer a more simplistic shooting experience. The built-in USB updating port on the VILTROX lens also offers future-proofing, which is a significant advantage for users of evolving E-mount cameras.

With a price tag of $469.00, the Canon RF45mm F1.2 STM is positioned as a premium product, reflecting its advanced features and optical quality. In contrast, the VILTROX 28mm F4.5 is priced at just $99.00, making it a highly attractive option for budget-conscious photographers. This represents a difference of $370, indicating that the VILTROX lens is about 79% cheaper.
