Canon EF-S 18- vs Canon RF

Price Comparison

The Canon EF-S 18-135mm f/3.5-5.6 is STM is priced at $329.95, making it about 44% cheaper than the Canon RF 85mm F2 Macro is STM, which costs $589.00. This significant price difference can influence a buyer’s decision, especially for those on a budget. While both lenses offer unique features and capabilities, the lower price of the EF-S lens makes it a more attractive option for entry-level photographers or casual users who seek versatility without a hefty investment.

Focal Length and Versatility

The Canon EF-S 18-135mm f/3.5-5.6 is STM offers a versatile focal length range of 18-135mm, making it suitable for a wide variety of shooting situations. This range allows users to capture everything from wide landscapes to close-up portraits. In contrast, the Canon RF 85mm F2 Macro is STM has a fixed focal length of 85mm, which is excellent for portraits and macro photography but less versatile for broader photographic needs. For those who value flexibility in their lens choice, the EF-S 18-135mm may be the clear winner.

Aperture and Low-Light Performance

The RF 85mm F2 Macro is STM features a bright f/2 aperture, which excels in low-light conditions and creates stunning bokeh. This makes it an ideal choice for portrait photography, where you want to isolate your subject from the background. The EF-S 18-135mm has a maximum aperture that ranges from f/3.5 to f/5.6, which is less effective in low-light scenarios. Therefore, if low-light performance and depth of field are your primary concerns, the RF 85mm lens presents a distinct advantage.

Image Stabilization

For image stabilization, the RF 85mm F2 Macro is STM offers up to 5 stops of shake correction, which is beneficial for both macro and low-light photography. The EF-S 18-135mm f/3.5-5.6 is STM features a refined Image Stabilization system, delivering up to four equivalent stops of shake correction. While both lenses provide solid stabilization, the RF 85mm's superior stabilization makes it particularly advantageous for handheld shots, especially in challenging lighting conditions.

Build Quality and Design

Both lenses are designed with the user in mind, but they cater to slightly different preferences. The EF-S 18-135mm f/3.5-5.6 is STM is more compact and lightweight, making it a suitable choice for travel and everyday photography. Conversely, the RF 85mm F2 Macro is STM is also lightweight but designed with a more robust build quality that reflects its macro capabilities. The inclusion of a control ring on the RF 85mm lens allows for direct setting changes, enhancing its usability for professional photographers.

Compatibility

The EF-S 18-135mm f/3.5-5.6 is STM is compatible with Canon's APS-C DSLRs, making it an excellent choice for users of Canon's Rebel series and similar cameras. The RF 85mm F2 Macro is STM, however, is specifically designed for Canon's full-frame mirrorless cameras, such as the EOS RP, EOS R, EOS R5, and EOS R6. If you are already invested in Canon's mirrorless system, the RF 85mm lens would be the better choice; otherwise, the EF-S lens provides broader compatibility for DSLR users.

Intended Use Cases

The Canon EF-S 18-135mm f/3.5-5.6 is STM is marketed as a versatile lens suitable for both video and still images, making it ideal for casual shooters or those who want a single lens to handle various situations. It excels at capturing a wide range of subjects, from landscapes to portraits. On the other hand, the RF 85mm F2 Macro is STM shines in portrait, macro, and low-light photography, making it perfect for photographers who specialize in these areas. Your choice will depend largely on your primary photography needs.

Which should you buy?

Choosing between the Canon EF-S 18-135mm f/3.5-5.6 is STM and the Canon RF 85mm F2 Macro is STM ultimately depends on your specific photography needs and budget. If versatility and price are your main concerns, the EF-S lens is a more economical option that covers a broader range of scenarios. However, if you prioritize low-light performance, beautiful bokeh, and macro capabilities, the RF 85mm lens justifies its higher price with superior features. Consider what you value most in your photography to make the best choice.
