The world of Canon lenses offers a wide range of options for photographers, each with its unique characteristics, advantages, and uses. In this comparison, we'll delve into two popular Canon lenses: the Canon RF 85mm f/2 Macro IS STM and the Canon RF 50mm f/1.8 STM. Both lenses are part of the RF mount system, designed for use with Canon's EOS R series mirrorless cameras, but they serve different purposes and cater to different needs.

Canon RF 85mm f/2 Macro IS STM

The Canon RF 85mm f/2 Macro IS STM is a versatile lens that combines the qualities of a medium telephoto lens with the capabilities of a macro lens. Its focal length of 85mm makes it an excellent choice for portrait photography, offering a flattering perspective and a comfortable working distance from your subject. The aperture of f/2 provides a shallow depth of field, which is ideal for isolating subjects and creating beautiful bokeh.

One of the standout features of this lens is its macro capability, allowing for 1:2 magnification (or half life-size). This feature makes it suitable not only for portraits but also for capturing detailed images of small objects, such as jewelry, watches, or even tiny insects. The inclusion of Image Stabilization (IS) is another significant advantage, providing up to 5 stops of stabilization according to Canon's measurements. This feature helps reduce camera shake and blur caused by hand movement, making it easier to achieve sharp images in low-light conditions or when using slower shutter speeds.

Canon RF 50mm f/1.8 STM

The Canon RF 50mm f/1.8 STM is a compact, lightweight lens that embodies the spirit of a classic prime lens. With its wide aperture of f/1.8, it excels in low-light situations and provides an exceptionally shallow depth of field, making it perfect for creating portraits with beautifully blurred backgrounds. The 50mm focal length is considered standard or normal, closely matching the human eye's field of view, which makes it versatile for everyday photography, including street, documentary, and indoor photography.

This lens is designed to be compact and affordable, making it an excellent entry-point for those looking to explore the world of prime lenses. Its STM (Stepping Motor) technology ensures smooth and quiet autofocus operation, which is beneficial for both stills photography and video recording. However, unlike the RF 85mm f/2 Macro IS STM, this lens does not feature image stabilization or macro capabilities.

Comparison

  • Purpose and Use: The Canon RF 85mm f/2 Macro IS STM is geared towards those who need a lens for portraits and macro photography, offering flexibility with its medium telephoto focal length and macro capabilities. In contrast, the Canon RF 50mm f/1.8 STM is more suited for general photography, low-light conditions, and those looking for a compact prime lens for everyday use.
  • Aperture: While both lenses have wide apertures, the RF 50mm f/1.8 STM has a slightly wider aperture, which can be beneficial in extremely low-light conditions or when a shallower depth of field is desired.
  • Image Stabilization: The inclusion of IS in the RF 85mm f/2 Macro IS STM gives it an edge in terms of versatility and usability in various lighting conditions, especially for handheld shooting.
  • Macro Capability: The RF 85mm f/2 Macro IS STM's ability to achieve 1:2 macro magnification sets it apart for those interested in close-up photography.
  • Size and Weight: The RF 50mm f/1.8 STM is significantly more compact and lighter, making it easier to carry around for casual or travel photography.

Conclusion

Both the Canon RF 85mm f/2 Macro IS STM and the Canon RF 50mm f/1.8 STM are valuable additions to the canon lenses lineup, each catering to different photographic needs. The choice between them depends on your specific requirements: if you're looking for a lens that can handle portraits with elegance and also delve into the world of macro photography with the added benefit of image stabilization, the RF 85mm f/2 Macro IS STM is the better choice. On the other hand, if you prefer a compact, versatile prime lens for everyday photography that excels in low-light conditions, the RF 50mm f/1.8 STM is an excellent option. Ultimately, understanding your photographic goals and preferences will guide you in selecting the most appropriate lens from these two outstanding canon lenses.
