Canon EF vs Rokinon

Overview of the Canon EF 50mm f/1.8 STM Lens

The Canon EF 50mm f/1.8 STM Lens is priced at $155.99, making it a budget-friendly option for photographers seeking a versatile prime lens. This lens is particularly well-suited for portraits, action, and nighttime photography, thanks to its bright f/1.8 maximum aperture. It features a minimum focusing distance of 1.15 feet (0.35m) and a maximum magnification of 0.21x, which allows for creative depth of field control. The lens utilizes a stepping motor (STM) for near-silent autofocus, enhancing the shooting experience, especially during video recording.

Overview of the Rokinon 14mm f/2.8 IF ED Super Lens

In contrast, the Rokinon 14mm f/2.8 IF ED Super Lens is available for $231.25, making it about 48% more expensive than Canon's offering. This lens is designed for those who need an ultra-wide perspective, featuring a remarkable 115.7° angle of view that excels in landscape and astrophotography. The fast f/2.8 maximum aperture provides optimized low-light performance, making it suitable for capturing bright and clear images in challenging environments. The Rokinon's robust construction ensures durability, while the manual focus capability allows for precise focus control.

Image Quality Comparison

When it comes to image quality, the Rokinon lens leads with its advanced optical design, which includes 14 elements in 10 groups. This configuration is designed to deliver exceptional sharpness and clarity across the entire frame, making it ideal for professional photography. The Rokinon lens utilizes aspherical elements to minimize distortion and chromatic aberrations, ensuring high-quality images with accurate color rendition. On the other hand, the Canon lens, while known for its good performance, does not match the Rokinon's level of optical sophistication. Thus, for photographers who prioritize image quality, the Rokinon lens is the superior choice.

Focal Length and Versatility

The Canon EF 50mm f/1.8 STM Lens offers a standard focal length that is versatile for various photography styles. It effectively serves as a 50mm lens on full-frame cameras and an 80mm equivalent on APS-C cameras, making it a great option for portraiture and close-up work. The Rokinon 14mm lens, however, caters to a different segment, providing a wide-angle view that is particularly beneficial for landscapes and real estate photography. Its 14mm focal length provides a dramatic perspective, which is useful for capturing expansive scenes. Depending on the type of photography you engage in, one lens may offer more versatility than the other.

Low-Light Performance

In low-light conditions, the Canon lens shines with its f/1.8 aperture, allowing for excellent light-gathering capabilities. This feature is beneficial for nighttime photography and situations where flash is impractical. The Rokinon lens, with a maximum aperture of f/2.8, also performs well but does not quite match the light-gathering prowess of the Canon. While both lenses are suitable for low-light photography, the Canon lens has the edge when it comes to capturing images in darker settings, making it a better choice for photographers who often shoot in such environments.

Build Quality and Design

The Rokinon lens boasts a more robust build, weighing 31.7oz (900g) and designed for durability, which makes it suitable for professional use in various conditions. Its larger size and weight may be a consideration for some users, particularly those who prioritize portability. In contrast, the Canon EF 50mm f/1.8 STM Lens is compact and lightweight, making it an excellent option for everyday use and travel. This aspect of the Canon lens can be especially appealing for photographers who prefer to carry minimal gear.

Autofocus and Usability

The Canon EF 50mm f/1.8 STM Lens features a stepping motor (STM) for smooth and quiet autofocus, which is particularly advantageous for video recording. This near-silent operation can significantly enhance the overall shooting experience. The Rokinon lens, while offering precision manual focus, does not come with autofocus capabilities, which may deter some users who rely heavily on this feature. Hence, for photographers who value ease of use and quick adjustments, the Canon lens is the better option.

Which should you buy?

Choosing between the Canon EF 50mm f/1.8 STM Lens and the Rokinon 14mm f/2.8 IF ED Super Lens ultimately depends on your specific photography needs. The Canon lens is about 17% cheaper at $155.99, making it an excellent choice for those focused on portraits and low-light photography. However, if you require an ultra-wide perspective for landscapes or real estate photography, the Rokinon lens, despite its higher price of $231.25, offers superior image quality and a wider angle of view. Each lens has its strengths, so the best choice will align with your photography style and requirements.
