Focal Length and Versatility
The Canon RF-S55-210mm offers an impressive telephoto range equivalent to 88–336mm on APS-C cameras, making it versatile for both landscape and portrait photography. This broad range allows users to capture distant subjects with detail. On the other hand, the Rokinon 14mm provides a wide-angle perspective with a 115.7° angle of view, making it perfect for landscapes and astrophotography. The choice between these lenses ultimately depends on whether you prioritize zoom versatility or a wide-angle capability.
Image Quality
When it comes to image quality, the Canon RF-S55-210mm lens is equipped with two Ultra-low Dispersion (UD) glass elements and one aspheric element, enhancing sharpness and reducing chromatic aberration. It also features Canon Super Spectra Coating to minimize ghosting and flare. The Rokinon 14mm lens excels in sharpness across the entire frame with its 14 elements in 10 groups, designed for exceptional detail. Both lenses promise high-quality images but cater to different photographic styles.
Low-Light Performance
The Rokinon 14mm f/2.8 shines in low-light conditions with its fast f/2.8 maximum aperture, allowing photographers to capture clear images even in challenging environments. This feature makes it particularly suitable for nighttime and indoor photography. In contrast, the Canon RF-S55-210mm has a maximum aperture of f/5-7.1, which may limit its performance in low-light situations compared to the Rokinon. If low-light shooting is a priority for you, the Rokinon lens is the better option.
Focusing Mechanism
The Canon RF-S55-210mm features Canon’s STM stepping motor, which supports smooth, quiet, and continuous focus adjustments, particularly beneficial for video recording. Its minimum focus distance of approximately 28.7 inches allows for decent close-up shots. Conversely, the Rokinon 14mm lens relies on manual focus, which offers precise control but may not be as convenient for quick adjustments. This distinction is crucial for those who prioritize autofocus capabilities in their photography.
Price Comparison
The price difference between the Canon RF-S55-210mm at $409.00 and the Rokinon 14mm at $231.25 is significant—approximately $177.75. This makes the Rokinon lens about 43% cheaper than the Canon lens. This price disparity could be a deciding factor for photographers on a budget or those looking to invest in multiple lenses without breaking the bank.

Each lens has unique strengths, so consider what aspects are most important for your photography endeavors.
