Canon RF-S18- vs Rokinon

Overview

When it comes to choosing the right lens for your photography needs, the Canon RF-S18-45mm F4.5-6.3 Lens and the Rokinon 14mm f/2.8 IF ED Super Lens for Canon EF offer distinct advantages. The Canon lens is priced at $87.00, making it about 62% cheaper than the Rokinon lens, which costs $231.25. Understanding their features, image quality, and intended use can help you make an informed decision.

Design and Build Quality

The Canon RF-S18-45mm is a compact and lightweight standard zoom lens designed for APS-C cameras, making it an ideal travel companion. It features a clever lens retraction mechanism that allows it to fit easily into small bags or even pockets. In contrast, the Rokinon 14mm lens is constructed with a robust design, weighing 31.7oz, which may be cumbersome for some users. However, its solid build ensures durability and reliability for professional use in various conditions.

Focal Length and Versatility

The Canon RF-S18-45mm offers a versatile zoom range of 18-45mm, which allows for a variety of shooting scenarios from wide-angle to slightly more zoomed-in shots. This adaptability makes it suitable for everyday photography, whether you're capturing landscapes or portraits. On the other hand, the Rokinon lens boasts a fixed focal length of 14mm, providing an ultra-wide perspective with a remarkable 115.7° angle of view. While this lens excels in capturing expansive scenes, it lacks the flexibility offered by the Canon lens.

Image Quality

In terms of image quality, the Rokinon 14mm lens is designed with 14 elements in 10 groups, ensuring exceptional sharpness and clarity across the entire frame. This makes it ideal for landscapes and astrophotography, where detail is paramount. The Canon RF-S18-45mm also prioritizes image quality, featuring two Aspheric elements and Canon's Super Spectra Coating to enhance color accuracy and reduce flare. While both lenses deliver impressive results, the Rokinon may have the edge in sharpness, particularly in specialized photography.

Low-Light Performance

Low-light performance is critical for many photographers. The Rokinon 14mm lens has a fast f/2.8 maximum aperture, allowing it to capture bright and clear images in challenging lighting conditions. This feature is especially beneficial for night sky photography or indoor settings without flash. The Canon RF-S18-45mm, with its f/4.5-6.3 aperture range, may struggle more in low-light situations, although it does offer optical image stabilization at up to 4 stops, which can help mitigate blur in some scenarios.

Autofocus and Operation

The Canon RF-S18-45mm is equipped with a lead screw-type stepping motor (STM), ensuring smooth and quiet autofocus operation. This makes it a great choice for video recording, as it minimizes background noise during shooting. The Rokinon lens, however, relies on manual focus, which allows for precise control but may not be as user-friendly for those accustomed to autofocus systems. This distinction can greatly affect usability, especially for beginners or those who frequently shoot video.

Price Comparison

At $87.00, the Canon RF-S18-45mm lens is a budget-friendly option, making it accessible to a broader range of photographers. In contrast, the Rokinon lens, priced at $231.25, is aimed at those who are willing to invest more for specific features and performance benefits. The Canon lens is about 62% less expensive than the Rokinon, which can be a significant factor for hobbyists or those just starting in photography.

Which should you buy?

Choosing between the Canon RF-S18-45mm F4.5-6.3 Lens and the Rokinon 14mm f/2.8 IF ED Super Lens ultimately depends on your specific needs as a photographer. If you require a versatile, lightweight lens for general photography and video, the Canon lens is an excellent choice due to its affordability and practicality. However, if your focus is on capturing expansive landscapes or astrophotography with exceptional sharpness, the Rokinon lens may be worth the investment despite its higher price. Consider your photography style and budget to determine which lens aligns best with your creative vision.
