Price Comparison
The Canon RF100-400mm F5.6-8 IS USM is priced at $699.00, while the Canon RF14-35mm F4 L IS USM Lens comes at a significantly higher price of $1,398.95. This makes the RF100-400mm about 50% cheaper than its counterpart. For photographers on a budget or those just starting, the more accessible price of the RF100-400mm may be appealing, especially given its versatile features for wildlife and sports photography. On the other hand, the RF14-35mm, being a professional-grade wide-angle lens, justifies its price with advanced optical technologies and a constant f/4 aperture throughout its zoom range.
Purpose and Use Cases
The RF100-400mm F5.6-8 IS USM is designed primarily for telephoto applications like wildlife and sports photography. Its extensive zoom range allows for capturing distant subjects with clarity. In contrast, the RF14-35mm F4 L IS USM Lens excels in wide-angle shots, making it ideal for landscape, architecture, and vlogging. This distinction in purpose means that the choice between these two lenses heavily relies on the type of photography or videography you intend to pursue.
Image Stabilization
Both lenses feature impressive image stabilization capabilities, but the RF100-400mm shines with up to 6 stops of shake correction when paired with EOS R series cameras that have In-Body Image Stabilization. The RF14-35mm provides up to 5.5 stops of stabilization. This difference may seem minimal, but for photographers shooting at longer focal lengths, the extra stability of the RF100-400mm can make a noticeable difference in image sharpness, especially in challenging lighting conditions.
Autofocus Performance
The autofocus capabilities of both lenses are noteworthy, but the RF100-400mm is equipped with Canon's Nano USM technology, which offers high-speed, smooth, and quiet focusing. This can be particularly beneficial in situations where capturing fast-moving subjects is crucial. The RF14-35mm also features advanced optics, but the RF100-400mm may have a slight edge in dynamic shooting scenarios due to its specialized autofocus system. The difference in autofocus performance can significantly impact the shooting experience depending on the subjects and environments.
Build Quality and Design
While both lenses are built to high standards, the RF14-35mm boasts L-series optical construction, known for its superior durability and image quality. It has a compact design weighing around 1.2 lbs, similar to the RF85mm F2 IS STM lens. The RF100-400mm is also compact and lightweight for a telephoto lens, making it easy to carry on long shoots. However, those who prioritize ruggedness and top-tier optical performance may find the RF14-35mm's construction more appealing, particularly for professional settings.
Focal Length Versatility
The RF100-400mm offers a remarkable zoom range from 100mm to 400mm, allowing photographers to capture distant subjects with ease. This range is complemented by its ability to accept RF tele extenders, further extending its focal length up to 800mm. In contrast, the RF14-35mm covers a wide-angle range from 14mm to 35mm, ideal for capturing expansive scenes. Depending on your photography style, the versatility of the RF100-400mm may cater better to those needing a longer reach, while the RF14-35mm serves those looking for broader perspectives.
Minimum Focusing Distance
The minimum focusing distance is another essential factor. The RF100-400mm has a minimum focusing distance of 2.89 feet at 200mm, allowing for decent close-ups at longer focal lengths. Meanwhile, the RF14-35mm has a closer focusing distance of just 7.9 inches, which is beneficial for capturing intricate details in wide-angle shots. If macro-style photography is a priority for you, the RF14-35mm provides more creative opportunities for close-up work, whereas the RF100-400mm is suited for distance shooting.
Which should you buy?
Choosing between the Canon RF100-400mm F5.6-8 IS USM and the Canon RF14-35mm F4 L IS USM Lens ultimately depends on your specific photography needs. If you require a versatile telephoto lens that is budget-friendly and excellent for wildlife or sports, the RF100-400mm is the clear winner at $699.00. However, if your focus is on wide-angle photography, landscapes, or vlogging, and you are willing to invest in superior optics, the RF14-35mm at $1,398.95 presents a compelling option. Each lens has unique strengths, making them suitable for different types of photographers.
