Priced at $239.00, the RF75-300mm lens is about 53% cheaper than the EF 24-105mm lens, which costs $509.00. This price difference of $270 highlights the RF75-300mm's value, especially for those who are budget-conscious while still wanting to invest in quality glass. For photographers looking for a versatile zoom lens without breaking the bank, the RF75-300mm is a compelling choice.
Build and Design
In terms of build and design, the Canon RF75-300mm F4-5.6 is compact and lightweight, making it easy to carry around, comparable to the weight of a 500ml water bottle. This portability is a significant advantage for photographers who are often on the move. On the other hand, the Canon 344B006 EF 24-105mm lens, while well-built and durable, does not emphasize portability in the same way. It is designed for professional use and comes with a filter size of 77mm. The choice here largely depends on whether you prioritize portability or professional-grade performance.
Focal Length and Versatility
The focal length differences between these two lenses offer distinct advantages. The Canon RF75-300mm provides an impressive zoom range, allowing for a focal length of up to 300mm, which is great for capturing distant subjects. In contrast, the Canon 344B006 EF 24-105mm lens offers a versatile range from 24mm to 105mm, making it suitable for various photography styles, from landscapes to portraits. This versatility in the EF 24-105mm could be particularly appealing for photographers who prefer an all-in-one solution for different shooting scenarios.
Autofocus and Performance
The Canon RF75-300mm lens features advanced autofocus capabilities, including eye detection at the 300mm zoom range. This functionality allows for precise focusing on subjects' pupils, which is beneficial for capturing dynamic scenes, especially in portrait and wildlife photography. Meanwhile, the Canon 344B006 EF 24-105mm lens incorporates a silent ultrasonic motor (USM) for reliable autofocus operation, making it suitable for various shooting environments. If you prioritize eye-detection technology for action shots, the RF75-300mm may be the better option; however, the USM in the EF 24-105mm provides reliable performance in quieter settings.
Included Accessories
When it comes to included accessories, the Canon RF75-300mm comes with a UV filter, lens cap keeper, and a cleaning kit, which adds value for buyers looking to maintain their lens. These accessories help safeguard the lens and keep it in optimal working condition. In contrast, the Canon 344B006 EF 24-105mm lens does not specify any included accessories beyond the standard warranty, which may be a consideration for photographers who appreciate having extra tools for maintenance and protection.

Both lenses are from Canon, a well-respected brand in the photography industry known for its quality optics. The Canon 344B006 EF 24-105mm lens has a sales rank of 1703, indicating its popularity among buyers and suggesting a solid reputation. Although the RF75-300mm does not have a specified sales rank, Canon’s reputation for producing reliable and high-quality lenses supports its credibility. Choosing between these two lenses may come down to how much weight you place on brand reputation alongside specific features.
Ideal Use Cases
The ideal use cases for these lenses vary significantly. The Canon RF75-300mm lens is tailored for photographers who often shoot distant subjects, such as wildlife or sports, due to its extensive zoom range. Its lightweight design makes it perfect for outdoor adventures. Conversely, the Canon 344B006 EF 24-105mm lens is better suited for professional photographers who require versatility in a single lens, allowing them to switch between landscape and portrait photography seamlessly. Understanding your primary photography needs will help determine which lens is right for you.
