Introduction to the Canon Lenses

When it comes to choosing a lens for your Canon camera, two standout options are the Canon RF 85mm F2 Macro IS STM and the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens. Each lens serves different photographic needs and comes with its own set of advantages. Understanding these differences can help you make an informed decision based on your photography style and requirements.

Price Comparison

In terms of pricing, the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens is slightly more budget-friendly, retailing at $569.00 compared to the Canon RF 85mm F2 Macro IS STM, which is priced at $589.00. This makes the RF-S18-150mm about 3.4% cheaper than its counterpart. While the price difference is minimal, it could be a deciding factor for photographers looking to maximize their budget without sacrificing quality.

Lens Type and Versatility

The Canon RF 85mm F2 Macro IS STM is a medium-telephoto lens designed primarily for portrait and macro photography, offering a maximum magnification of 0.5x. Its bright f/2 aperture allows for beautiful bokeh, making it ideal for low-light conditions and creative depth-of-field effects. In contrast, the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens features a versatile zoom range from 18mm to 150mm, making it suitable for a wide range of subjects, from landscapes to sports. This zoom capability allows for greater flexibility in various shooting scenarios, whereas the RF 85mm is more specialized.

Image Stabilization Features

Both lenses come equipped with image stabilization, but they differ in effectiveness. The Canon RF 85mm offers optical image stabilization with up to 5 stops of shake correction, which is particularly beneficial for low-light conditions and macro photography. On the other hand, the Canon RF-S18-150mm features in-lens optical image stabilization with up to 4.5 stops of correction, and this can increase to 6.5 stops when paired with EOS R series cameras that have In-Body Image Stabilizer (IBIS). This makes the RF-S18-150mm a solid choice for dynamic shooting, especially when capturing video.

Autofocus Performance

Autofocus is crucial for both still photography and video, and both lenses have strengths in this area. The RF 85mm utilizes a control ring for direct setting changes, enhancing the user experience when switching focus modes. While the RF-S18-150mm boasts a lead screw-type STM for smooth and quiet autofocusing, which is particularly advantageous for videographers needing to minimize background noise. Each lens is designed to provide reliable focus, but the RF-S18-150mm may have a slight edge in video applications due to its quieter operation.

Compatibility and Usage

The Canon RF 85mm F2 Macro IS STM is compatible with Canon's full-frame mirrorless cameras, such as the EOS R, EOS RP, and EOS R5, making it ideal for photographers who own these higher-end models. In contrast, the RF-S18-150mm is designed for APS-C cameras but can be used on full-frame EOS R-series cameras with automatic cropping. This versatility means that the RF-S18-150mm can appeal to a broader range of users, particularly those who may not yet have invested in a full-frame camera.

Ideal Photography Scenarios

Choosing between these lenses often comes down to the type of photography you pursue. The RF 85mm is perfect for portrait and macro photography, providing stunning background blur and sharp focus on subjects. The RF-S18-150mm, with its wide zoom range, excels in everyday shooting scenarios, making it an excellent all-around lens for landscapes, family gatherings, and travel photography. Depending on your photographic needs, one lens may suit you better than the other.

Which should you buy?

Ultimately, the choice between the Canon RF 85mm F2 Macro IS STM and the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens hinges on your specific photography needs. If you are a portrait photographer who values bokeh and macro capabilities, the RF 85mm is the better option. However, if you seek versatility and a lens that can handle a wide range of scenarios, the RF-S18-150mm offers greater flexibility at a slightly lower price. Consider your shooting style and the type of images you wish to capture before making your decision.
