Price Comparison

The Canon RF100-400mm is priced at $699.00, making it about 73% cheaper than the Canon RF24-70mm, which costs $2,599.00. This price difference is significant, especially for photographers on a budget or those who are just starting out. The lower price point of the RF100-400mm allows photographers to invest in additional accessories or even other lenses. While the RF24-70mm offers professional-grade features and capabilities, the RF100-400mm provides exceptional value for those seeking a quality telephoto lens without breaking the bank.

Image Quality

Both lenses deliver high image quality, but they cater to different photographic needs. The RF100-400mm is specifically designed for telephoto photography, making it ideal for capturing distant subjects with clarity and detail. It features a single Ultra Low Dispersion lens element that corrects chromatic aberration, ensuring images are sharp and vibrant across the zoom range. The RF24-70mm, on the other hand, excels in versatility and low-light performance with its f/2.8 aperture. This lens is designed to deliver exceptional image quality across a wider range of shooting scenarios, making it suitable for everything from portraits to landscapes.

Autofocus Performance

The autofocus systems in both lenses are designed for speed and accuracy, but they differ in their applications. The RF100-400mm utilizes Canon’s Nano USM technology, providing high-speed and smooth autofocus, which is particularly beneficial for tracking fast-moving subjects in wildlife and sports photography. The RF24-70mm also features Nano USM, ensuring smooth and silent autofocus, which is crucial for video work and when shooting in quiet environments. Both lenses are engineered for responsive performance, but the choice between them may depend on the specific focus requirements of your photographic style.

Build Quality and Design

Build quality is another area where the Canon RF24-70mm stands out, thanks to its L-series construction. This lens offers a dust- and weather-resistant design, making it a reliable choice for outdoor photography in various conditions. The RF100-400mm, while compact and lightweight, does not carry the same level of environmental sealing. However, its lightweight design makes it more portable, which is advantageous for travel and wildlife photography where every ounce counts. Photographers who frequently shoot in harsh environments may prefer the RF24-70mm for its rugged build, while those prioritizing portability might opt for the RF100-400mm.

Versatility in Use

The RF100-400mm shines in specialized telephoto applications, particularly for wildlife and sports photography, where the ability to zoom in on distant subjects is crucial. Its versatility is enhanced by the option to use tele extenders, allowing for an effective maximum focal length of 800mm when paired with the RF2x extender. Conversely, the RF24-70mm is a true all-rounder, making it suitable for a wide range of photography genres, from event and portrait photography to landscapes. Its focal length range is more versatile for everyday shooting, making it a go-to option for many photographers.

Which should you buy?

Choosing between the Canon RF100-400mm F5.6-8 IS USM and the Canon RF24-70mm F2.8 L IS USM Lens ultimately depends on your specific photographic needs and budget. If you are looking for a cost-effective option that excels in telephoto photography, the RF100-400mm, priced at $699.00, is a strong contender. It offers impressive zoom capabilities and portability, making it ideal for wildlife and sports photography. On the other hand, if you require a premium lens that delivers exceptional versatility and image quality across various shooting conditions, the RF24-70mm is worth the investment at $2,599.00. Consider where and how you plan to use the lens to make the best choice for your photography journey.
