Overview of Canon EF 50mm f/1.8 STM Lens and Rokinon 14mm f/2.8 IF ED Super Lens

The Canon EF 50mm f/1.8 STM Lens is priced at $169.00, while the Rokinon 14mm f/2.8 IF ED Super Lens is available for $231.25, making the Canon lens about 17% cheaper. Each lens caters to different photographic needs, making them suitable for distinct types of photography. The Canon lens is well-regarded for portraiture and low-light conditions, while the Rokinon lens shines with its ultra-wide perspective, ideal for landscapes and astrophotography.

Design and Build Quality

The Canon EF 50mm f/1.8 STM Lens is compact and lightweight, weighing approximately 5.6 ounces, which enhances its portability for everyday use. In contrast, the Rokinon 14mm f/2.8 IF ED Super Lens is more robust, weighing 31.7 ounces, which indicates a more durable construction suitable for professional use. Its larger size may be less convenient for casual photographers but offers increased reliability. The design choices reflect their intended uses, with Canon's lens being a versatile everyday option and Rokinon's lens tailored for more specialized applications.

Focal Length and Aperture

The Canon EF 50mm lens features a focal length of 50mm with a maximum aperture of f/1.8, making it ideal for creating a shallow depth of field that enhances portrait photography. It performs well in low-light conditions, allowing for sharper images without excessive motion blur. On the other hand, the Rokinon 14mm lens has a wider 14mm focal length with a maximum aperture of f/2.8. This design is optimized for capturing expansive scenes, making it particularly useful for landscape and astrophotography. The difference in focal lengths and apertures aligns with their specific photography niches.

Optical Performance

Optically, the Canon EF 50mm f/1.8 STM Lens boasts a construction of 6 elements in 5 groups, designed to minimize ghosting and flare while maintaining excellent color balance. It delivers sharp images with beautiful background blur. In comparison, the Rokinon 14mm f/2.8 lens is built with 14 elements in 10 groups, which includes aspherical lens elements to reduce distortion and aberrations. This advanced optical design enables it to excel in providing stunningly detailed images across the entire frame, crucial for capturing intricate landscape details.

Focusing Mechanism

The Canon lens features a Stepping Motor (STM) for near-silent and continuous autofocus, making it ideal for both still photography and video recording. This is particularly advantageous for capturing fleeting moments without disrupting the scene with focusing noise. The Rokinon lens, however, relies on precision manual focus, which some photographers may prefer for its control and accuracy, especially in specialized scenes like landscapes. This manual focus allows for fine-tuning to achieve optimal sharpness, although it may not be as convenient for rapid shooting conditions.

Price Comparison

The Canon EF 50mm f/1.8 STM Lens is priced at $169.00, making it a cost-effective choice for entry-level photographers and those looking for a reliable prime lens. In contrast, the Rokinon 14mm f/2.8 IF ED Super Lens retails for $231.25, representing a significant investment for those who need an ultra-wide-angle lens. The approximately $62 difference in price highlights the value proposition of both lenses depending on the user’s needs. While the Canon lens is about 17% cheaper, the Rokinon lens offers specialized optical performance that may justify its higher cost for some users.

Use Cases

The Canon EF 50mm f/1.8 STM Lens is particularly well-suited for portrait, action, and nighttime photography, making it a versatile option for most photographers. Its effective focal length of 80mm on APS-C cameras allows for a comfortable distance from the subject while still capturing detailed portraits. Conversely, the Rokinon 14mm f/2.8 lens excels in landscape photography, real estate imagery, and astrophotography due to its ultra-wide 115.7° angle of view. This makes it an excellent choice for capturing vast scenes where depth and perspective are crucial.

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 photographic needs and budget. If you're looking for a versatile, cost-effective lens suitable for portraits and low-light conditions, the Canon lens is an excellent choice at $169.00.
