Price Comparison
The VILTROX 56mm F1.7 Fuji XF is about 17% cheaper than the Canon RF 50mm F1.8 STM Lens. Priced at $180.00 compared to Canon’s $219.00, the VILTROX lens offers a more budget-friendly option for photographers. This price difference could be significant for those just starting their photography journey or for professionals looking to save on equipment costs. While both lenses are high-quality options, the lower price of the VILTROX lens may attract those who prioritize affordability without sacrificing performance.
Aperture and Low-Light Performance
The VILTROX lens has a slightly wider maximum aperture of f/1.7 compared to the Canon's f/1.8. This marginal difference allows the VILTROX lens to perform slightly better in low-light conditions, giving photographers a slight edge when capturing images in challenging lighting. The wider aperture also provides greater control over depth of field, which is crucial for portrait photography. Both lenses are designed to create beautiful background blur, but the VILTROX may have a slight advantage in low-light scenarios due to its improved aperture.
Compatibility with Camera Systems
The Canon RF 50mm F1.8 STM Lens is specifically designed for EOS R-Series cameras, ensuring optimal performance and compatibility within Canon's ecosystem. On the other hand, the VILTROX 56mm F1.7 Fuji XF is tailored for APS-C-format FUJIFILM X-mount mirrorless cameras, providing an equivalent focal length of 85mm. This means that users must consider their camera system when choosing between these two lenses. If you're already invested in the Canon system, the RF 50mm is the clear choice. Conversely, Fujifilm users will benefit most from the VILTROX lens.
Design and Weight
The VILTROX lens is notably lightweight, weighing only 171 grams, making it an excellent choice for travel and everyday use. In contrast, the weight of the Canon RF 50mm F1.8 STM Lens is not specified, but it is generally known that Canon's RF lenses are compact and lightweight. The VILTROX lens's lightweight design emphasizes portability, which is a vital feature for photographers who are often on the move. A lighter lens can enhance shooting comfort and reduce fatigue during long sessions.
Autofocus Technology
Both lenses feature advanced autofocus technology, but they excel in different ways. The Canon RF 50mm employs an STM motor for smooth, fast, and nearly silent autofocus performance, making it ideal for both photography and videography. The VILTROX lens also utilizes an STM stepper motor, providing a quiet autofocus experience that minimizes disruptions during photo or video shooting. While both lenses promise effective autofocus, the specific performance may vary depending on the camera body and shooting conditions.
Optical Quality
The VILTROX 56mm lens boasts a complex optical design that includes 9 groups and 11 pieces, featuring 4 ED lenses and 3 high refraction index lenses. This design helps to minimize aberrations and improve overall image quality. The Canon RF 50mm, while not explicitly detailed in terms of optical structure, includes an aspheric lens element and Super Spectra Coating to enhance image sharpness and color accuracy. Both lenses are engineered for high optical performance, but the VILTROX may provide a slight edge due to its advanced optical construction.
Bokeh Quality
The VILTROX lens features a nine-blade diaphragm, which is designed to create a pleasing bokeh quality. This characteristic is particularly important for portrait photographers who aim to achieve a soft background blur that enhances their subject. The Canon RF 50mm, while not specifically mentioned in terms of blade count, is known for producing attractive out-of-focus areas due to its wide aperture. Photographers seeking beautiful bokeh may find the VILTROX lens to be the preferred option, especially for portrait work.
Which should you buy?
Choosing between the Canon RF 50mm F1.8 STM Lens and the VILTROX 56mm F1.7 Fuji XF ultimately depends on your camera system and specific needs. If you are a Canon EOS R-Series user, the RF 50mm offers exceptional autofocus and image quality for $219.00. Conversely, the VILTROX lens is a fantastic choice for Fujifilm users, providing a slightly wider aperture, lightweight design, and lower price of $180.00. In terms of value, the VILTROX may stand out as the more economical option without compromising on quality, especially for those focused on portrait photography.
