The Rokinon 14mm f/2.8 IF ED Super Lens for Canon EF and the Sigma 28-70mm F2.8 DG DN for Sony E Black serve different photography needs. The Rokinon lens is distinctly an ultra-wide-angle option, ideal for capturing expansive landscapes and astrophotography, while the Sigma lens is a versatile standard zoom that covers a range from 28mm to 70mm. This versatility makes the Sigma lens suitable for various photography styles, from portraits to wider scenes.

Price Comparison

The price difference between the two lenses is significant. The Rokinon 14mm lens is priced at $231.25, while the Sigma 28-70mm lens costs $859.95. This puts the Sigma lens at approximately 273% more expensive than the Rokinon. If you're on a budget and primarily focused on wide-angle shots, the Rokinon offers a compelling option without breaking the bank. However, the price of the Sigma reflects its broader functionality, which may justify the investment for those who need a zoom lens.

Image Quality

When it comes to image quality, the Rokinon 14mm lens excels with its advanced optical design that includes 14 elements in 10 groups, providing superior sharpness and clarity. This lens is particularly designed to minimize distortion and chromatic aberrations, making it ideal for capturing detailed landscapes. On the other hand, the Sigma 28-70mm lens, based on the acclaimed 24-70mm F2.8 DG DN design, delivers impressive optical performance throughout its zoom range. Both lenses promise high-quality images, but the Rokinon may have an edge for ultra-wide shots, while the Sigma offers flexibility across various focal lengths.

Performance in Low Light

The Rokinon 14mm f/2.8 lens is optimized for low-light performance, with a fast f/2.8 maximum aperture that allows for bright and clear images in challenging lighting conditions. This feature is particularly beneficial for astrophotography and capturing landscapes during dawn or dusk. The Sigma 28-70mm lens also boasts a constant f/2.8 aperture, ensuring it performs well in low-light situations. While both lenses perform admirably in low light, the Rokinon's ultra-wide design may allow for more creative low-light photography opportunities.

Build Quality and Design

The Rokinon lens has a robust design, weighing 31.7 ounces (900g) and measuring 6.0 x 3.5 x 3.7 inches, ensuring durability for professional use. It also features a built-in petal-type lens hood, adding to its reliability in various shooting conditions. The Sigma lens is known for its superb build quality, lightweight, and compact body, making it suitable for everyday use. While both lenses are built to last, the Rokinon's heftier design reflects its focus on durability, while the Sigma's lightweight design enhances portability for everyday photographers.

Focus Mechanism

The Rokinon 14mm lens features a precision manual focus system, allowing photographers to fine-tune their shots for optimal sharpness and creative effects. This feature is particularly valuable for landscape and astrophotography where focus accuracy is crucial. In contrast, the Sigma 28-70mm lens includes an internal focusing system and a focus mode switch, providing more versatility for users who may prefer autofocus for faster shooting. While the Rokinon lens may appeal more to manual focus enthusiasts, the Sigma lens offers a modern approach to focusing, catering to a wider audience.

Intended Use

The intended use for each lens is quite distinct. The Rokinon 14mm lens is tailored for wide-angle photography, making it perfect for landscapes, real estate, and astrophotography. It excels in capturing expansive views with its 115.7° angle of view. Conversely, the Sigma 28-70mm lens serves as a standard zoom lens, making it suitable for a variety of photography styles, including portraits and street photography. If your focus is on wide-angle imagery, the Rokinon is the clear choice, while the Sigma provides flexibility across different shooting scenarios.

Which should you buy?
