Canon EF-S 55- vs Canon RF

Price Comparison

In terms of pricing, the Canon EF-S 55-250mm F4-5.6 is STM is significantly cheaper than the Canon RF 85mm F2 Macro is STM. The EF-S lens is priced at $329.99, while the RF lens comes in at $589.00, making the RF lens about 78% more expensive. This price difference may influence your choice depending on your budget and requirements as a photographer. The lower cost of the EF-S lens makes it more accessible for amateur photographers or those looking to invest less initially.

Focal Length and Versatility

The Canon EF-S 55-250mm offers a versatile focal length range of 55-250mm, making it ideal for a variety of photography styles, including wildlife and sports. In contrast, the Canon RF 85mm is a medium telephoto lens with a fixed focal length of 85mm, which is specifically suited for portraiture and macro photography. This means that while the EF-S lens provides more zoom capabilities, the RF lens is better for achieving beautiful bokeh and detailed close-ups. If you require versatility in your photography, the EF-S lens may serve you better, but if your focus is on portrait or macro photography, the RF lens excels in that area.

Image Stabilization Features

When it comes to image stabilization, the Canon RF 85mm takes the lead with its optical image stabilization offering up to 5 stops of shake correction. This feature is particularly beneficial in low-light situations or when recording video. In comparison, the Canon EF-S 55-250mm provides image stabilization for up to 3.5 stops, which, while helpful, is less effective than that of the RF lens. The superior stabilization in the RF lens makes it more suitable for macro and low-light photography, allowing for clearer, steadier shots without the need for a tripod.

Minimum Focusing Distance

The minimum focusing distance of each lens highlights their differing capabilities. The Canon EF-S 55-250mm has a minimum focusing distance of 2.79 feet, while the Canon RF 85mm allows for a closer focus at just 1.15 feet. This shorter focusing distance in the RF lens enhances its macro capabilities, enabling photographers to capture fine details up close. If macro photography is a significant aspect of your work, the RF lens's ability to focus more closely could be a deciding factor.

Aperture and Low-Light Performance

With respect to aperture, the Canon RF 85mm features a bright f/2 aperture, allowing for excellent low-light performance and beautiful bokeh, making it ideal for portraits and artistic shots. On the other hand, the Canon EF-S 55-250mm has a maximum aperture of f/4-5.6, which is less effective in low-light conditions. The wider aperture of the RF lens not only assists in low-light photography but also offers greater creative control over depth of field. This makes the RF lens a compelling choice for photographers who frequently shoot in varying lighting conditions or who prioritize aesthetic blur in their images.

Build Quality and Design

Both lenses are designed with portability in mind, but they cater to different needs. The Canon EF-S 55-250mm is compact and lightweight, making it suitable for travel and everyday use. In contrast, the Canon RF 85mm is also lightweight but is optimized for Canon's full-frame mirrorless cameras, featuring a control ring for direct setting changes. This thoughtful design makes the RF lens more user-friendly for those who value quick adjustments while shooting. If you're often on the move or prefer a lens that merges functionality with ease of use, both lenses have their merits, but the RF lens offers added convenience for quick shooting.

Compatibility

Compatibility is another important factor to consider. The Canon EF-S 55-250mm is designed for Canon's APS-C DSLR cameras, while the Canon RF 85mm is compatible with Canon's full-frame mirrorless cameras such as the EOS RP, EOS R, EOS R5, and EOS R6. If you own a full-frame mirrorless camera, the RF lens will be a perfect fit, whereas the EF-S lens is better suited for those with APS-C systems. This compatibility aspect can significantly impact your decision, depending on your existing camera setup.

Which should you buy?

Ultimately, the choice between the Canon EF-S 55-250mm F4-5.6 is STM and the Canon RF 85mm F2 Macro is STM hinges on your individual photography needs. If budget is a primary concern or if you require a versatile zoom lens for a variety of situations, the EF-S lens is about 78% cheaper and offers flexible focal lengths. However, if you prioritize superior image quality, low-light performance, and macro capabilities, the RF lens is worth its higher price tag, providing features that enhance portrait and close-up photography. Your specific photography style and budget will guide your final decision.
