The Canon RF 85mm f/2 Macro IS STM stands out as a versatile and accessible prime lens within Canon's growing RF mirrorless ecosystem. Designed for full-frame RF cameras, it distinguishes itself by combining a classic portrait focal length with genuine half-macro capabilities and effective image stabilization, aiming to be a multi-purpose tool for a wide range of photographers.
Optically, the RF 85mm f/2 Macro IS STM comprises 12 elements arranged in 11 groups. This optical formula, coupled with Canon's Super Spectra coating, is engineered to deliver sharp images while effectively minimizing ghosting and flare. The 85mm focal length is globally renowned as a flattering perspective for portraiture, offering a natural compression that helps subjects stand out from their backgrounds. The f/2 maximum aperture provides ample light-gathering capabilities and allows for significant subject isolation. While not as extreme as the f/1.2 or f/1.4 offerings, the f/2 aperture, combined with a 9-blade circular diaphragm, contributes to a pleasing bokeh quality, rendering out-of-focus areas smoothly and creating a visually appealing depth of field. Sharpness is generally strong across the frame, especially when stopped down slightly from wide open, providing excellent detail for its class.
A defining characteristic of this lens is its half-macro capability, signified by the "Macro" in its name. With a maximum magnification of 0.5x, users can focus as close as 0.35 meters (1.15 feet). This feature transforms the lens from a dedicated portrait optic into a highly capable tool for close-up photography. It allows photographers to capture intricate details of small subjects such as flowers, insects, textures, or product details without needing to carry a separate, dedicated macro lens. While not true 1:1 macro, 0.5x magnification is more than sufficient for many practical applications and significantly enhances the lens's overall utility, making it an excellent choice for those who appreciate capturing fine details.
Image stabilization is another critical asset integrated into the RF 85mm f/2 Macro IS STM. Its Optical Image Stabilization system is rated for up to 5 stops of shake correction. This is a substantial benefit, particularly when shooting handheld in challenging low-light conditions or at slower shutter speeds. It minimizes camera shake, allowing for sharper images and cleaner results by enabling lower ISO settings. This stabilization works in conjunction with in-body image stabilization (IBIS) found in some Canon RF camera bodies, further enhancing its effectiveness for stable handheld capture of both stills and video.
Autofocus is handled by a Stepping Motor (STM) AF system. This motor is known for its quiet and smooth operation, making it well-suited for video recording where distracting focus noise can be problematic. For still photography, the STM provides accurate and consistent focusing performance, which is perfectly adequate for the types of photography this lens excels in, such as portraits, close-ups, and street photography. While not the fastest focusing system in Canon's lineup, especially when compared to USM (Ultrasonic Motor) lenses for rapidly moving subjects, its reliability and quiet nature make it a practical choice for most general shooting scenarios.
In terms of build and handling, the RF 85mm f/2 Macro IS STM strikes a balance between portability and functionality. Weighing approximately 500 grams (1.1 lbs), it is relatively lightweight for an 85mm full-frame prime with stabilization and macro capabilities. The construction is primarily plastic, which contributes to its lighter weight, though it feels solid in hand. A notable feature is the customizable Control Ring, a standard on many RF lenses. This ring can be assigned various functions, such as aperture, ISO, or exposure compensation, allowing for quick and intuitive adjustments without needing to navigate menus or take your eye from the viewfinder. The 67mm filter thread is a common size, simplifying the acquisition of filters. It's worth noting that the lens does not feature explicit weather sealing, so appropriate care should be exercised in adverse environmental conditions.
The lens truly excels in several key use cases:
- Portraits: The 85mm focal length is a timeless choice for portraiture, offering a natural perspective and flattering subject compression. The f/2 aperture, combined with the 9-blade diaphragm, produces attractive bokeh, beautifully isolating subjects with pleasing depth. It is an ideal lens for headshots, upper-body, and full-body portraits, consistently delivering professional-looking results.
- Close-up Photography: Its half-macro capability (0.5x magnification) is a significant advantage, allowing photographers to delve into the intricate world of small details. This makes it an excellent option for capturing detailed shots of flowers, food, product details, or small crafts, adding a layer of versatility not commonly found in portrait primes.
- Low-Light Photography: The bright f/2 aperture, coupled with 5-stop Optical Image Stabilization, makes this lens highly competent in dim lighting conditions. It enables users to shoot handheld at slower shutter speeds, maintaining lower ISOs for cleaner images, and extending creative possibilities after sunset or in poorly lit interiors.
- Street Photography: While 85mm might be considered a longer focal length for traditional street photography, its compact size, quiet STM autofocus, and effective image stabilization make it a compelling choice for discreet candid shots. It allows photographers to capture subjects from a slight distance, providing a more intimate feel without being intrusive, and is versatile enough for environmental portraits within an urban setting.
In summary, the Canon RF 85mm f/2 Macro IS STM is a highly compelling lens for Canon RF mirrorless users seeking a versatile prime. It masterfully blends a classic portrait focal length with genuine half-macro capabilities and robust image stabilization, all within a reasonably compact and accessible package. For photographers specializing in portraits, close-up work, or those needing a capable lens for diverse shooting in varied lighting conditions, this lens offers remarkable value and performance, establishing itself as a smart and versatile addition to any RF kit.
