Canon RF24- vs Tamron 17-

Introduction to Canon RF24-105mm and Tamron 17-70mm

When comparing the Canon RF24-105mm F4-7.1 IS STM and the Tamron 17-70mm f/2.8 Di III-A VC RXD, it's essential to note that both lenses cater to different needs and camera systems. The Canon lens is priced at $459.00, while the Tamron lens comes in at $599.00, making the Canon about 17% cheaper. Understanding their features can help photographers decide which lens best fits their shooting style.

Zoom Range and Versatility

The Canon RF24-105mm offers a versatile zoom range of 24-105mm, making it suitable for landscapes, portraits, and travel photography. With a maximum magnification of 0.5x when using Center Focus Macro, it allows for detailed close-ups from as close as 0.43 feet. In contrast, the Tamron 17-70mm provides a focal length range of 17-70mm, which translates to a full-frame equivalent of 25.5-105mm. While both lenses cover similar focal lengths, the Canon's longer reach makes it slightly more versatile for various shooting scenarios.

Aperture and Low-Light Performance

The Tamron 17-70mm shines with a constant maximum aperture of f/2.8 across its zoom range, which is beneficial for low-light conditions and achieving a shallow depth of field. On the other hand, the Canon RF24-105mm has a variable aperture of f/4-7.1, which may limit its performance in dim lighting. This difference is significant for photographers who prioritize low-light capabilities, as the Tamron lens is designed to excel in such situations.

Image Stabilization

Both lenses feature advanced image stabilization systems, but they operate differently. The Canon RF24-105mm incorporates optical image stabilization with up to 5 stops of shake correction, which is crucial for handheld shooting. The Tamron 17-70mm also includes a Vibration Compensation (VC) mechanism, enhanced for video shooting by leveraging AI technology. This feature ensures stable footage, making the Tamron a great option for videographers who need to minimize camera shake.

Build Quality and Design

The Tamron 17-70mm lens boasts a moisture-resistant construction and a fluorine coating, making it more durable in challenging weather conditions. This quality may appeal to outdoor photographers who often shoot in unpredictable environments. In comparison, while the Canon RF24-105mm is compact and lightweight, its build quality does not emphasize weather resistance. Therefore, if durability is a priority, the Tamron lens may have the edge.

Autofocus Performance

The Canon RF24-105mm utilizes a leadscrew-type STM motor for smooth autofocusing, which is particularly beneficial for capturing video and ensuring sharp stills. This motor is designed to provide quiet and rapid focus adjustments, making it a solid choice for both photography and videography. Conversely, the Tamron 17-70mm lens is compatible with many of Sony's autofocus features, including Fast Hybrid AF and Eye AF, which can significantly enhance shooting speed and accuracy for portraits.

Practical Applications

The Canon RF24-105mm is ideal for photographers looking for a general-purpose lens that covers a wide range of subjects, from landscapes to close-up macro photography. Its compact size and lightweight design make it an excellent travel companion. On the other hand, the Tamron 17-70mm is tailored for everyday use, especially for those utilizing APS-C mirrorless cameras. Its constant f/2.8 aperture and advanced autofocus capabilities make it a practical choice for both stills and video in various shooting environments.

Which should you buy?

Ultimately, the choice between the Canon RF24-105mm and the Tamron 17-70mm depends on your specific needs. If you prioritize a wider zoom range and a lower price point, the Canon RF24-105mm is a compelling option. However, if low-light performance, build quality, and advanced autofocus features are more critical for your photography or videography, the Tamron 17-70mm may justify its higher price. Assess your shooting style, and select the lens that aligns with your photographic goals.
