Canon RF15- vs Canon RF28-

Introduction to the Lenses

In this comparison, we will look at two impressive lenses from Canon: the Canon RF15-35mm F2.8 L is USM Lens and the Canon RF28-70mm F2 L USM Lens. Both lenses are designed for EOS R series mirrorless cameras, but they cater to different photographic needs and styles. The RF15-35mm F2.8 is priced at $2398.95, while the RF28-70mm F2 comes in at $3399.00, making the former about 17% cheaper.

Image Quality

When it comes to image quality, both lenses offer high-resolution capabilities thanks to their L-series design. The RF15-35mm F2.8 is known for its bright f/2.8 maximum aperture, which allows for excellent performance in low-light conditions and achieves a broad depth of field. On the other hand, the RF28-70mm F2 excels with its constant f/2 aperture across its zoom range, providing even more control over depth of field and subject isolation. This distinction makes the RF28-70mm ideal for portraiture, while the RF15-35mm shines in landscape photography.

Focal Length Versatility

The RF15-35mm offers a focal length range from 15mm to 35mm, making it perfect for wide-angle shots, which is great for capturing expansive landscapes or architecture. Its wide perspective allows photographers to include more elements in their frame. Conversely, the RF28-70mm spans a focal length of 28mm to 70mm, making it more versatile for various types of photography, including portraits and event coverage. This additional range provides greater flexibility, allowing photographers to adapt to different scenes without changing lenses.

Autofocus Performance

Both lenses feature advanced autofocus systems, but they utilize different technologies to achieve swift and accurate focusing. The RF15-35mm F2.8 employs Canon's Nano USM technology, which provides high-speed, smooth, and quiet autofocus, making it an excellent choice for video as well as still photography. The RF28-70mm F2 similarly benefits from a fast autofocus system, supported by a 12-pin communication system, ensuring quick and reliable focusing. For photographers who prioritize silent operation, especially during video shoots, the RF15-35mm may have a slight edge due to its quieter autofocus performance.

Build Quality and Weather Resistance

In terms of build quality, both lenses are constructed to withstand challenging shooting conditions. The RF15-35mm is expertly sealed around its panels, switch, and lens mount to prevent water and dust from entering, making it a robust choice for outdoor photography. The RF28-70mm also boasts a dust- and water-resistant design, enhanced by a fluorine coating that protects the front element from dirt and smudges. This durability in both lenses ensures that photographers can take them into various environments without worrying about damage.

Minimum Focusing Distance

The RF15-35mm F2.8 has a minimum focusing distance of 0.92 feet (0.28 meters), allowing for close-up shots of subjects while still capturing the wider context of a scene. This feature is particularly beneficial for landscape and architectural photography where foreground elements can add depth to the image. In contrast, the RF28-70mm's minimum focusing distance is not specified, but its design is more suited for general photography rather than extreme close-ups. Therefore, for those who enjoy capturing detailed subjects up close, the RF15-35mm offers a distinct advantage.

Price Comparison

With a price tag of $2398.95, the RF15-35mm is significantly more affordable than the RF28-70mm, which costs $3399.00. This price difference of about $1000 makes the RF15-35mm a more accessible choice for photographers who may not want to invest heavily upfront. However, the RF28-70mm justifies its higher price with its exceptional low-light capabilities and constant f/2 aperture, appealing to those who prioritize professional-grade portrait and event photography.

Which should you buy?

Choosing between the Canon RF15-35mm F2.8 L is USM Lens and the Canon RF28-70mm F2 L USM Lens ultimately depends on your specific needs as a photographer. If you specialize in landscape photography or require a wide-angle lens that offers versatility and a more budget-friendly option, the RF15-35mm is an excellent choice. However, if you often shoot in low light or are focused on portrait photography, the RF28-70mm, with its constant f/2 aperture and greater focal length range, may be worth the extra investment. Consider your shooting style, budget, and the types of projects you pursue to make the best decision for your photography arsenal.
