The Canon RF 85mm f/1.2 lens has a large maximum aperture of f/1.2, which allows for a shallow depth of field, creating a pleasing background blur that isolates subjects.
This is particularly useful in live events where you may want to emphasize the main action or subject against a distracting background.

The focal length of 85mm is considered an ideal choice for portraiture as its compression can enhance facial features while maintaining a natural perspective, reducing distortion that might occur with wider-angle lenses.
The lens utilizes Canon's RF mount technology, which features an improved communication speed between the lens and camera, allowing for faster autofocus and better performance in low-light conditions, essential for live events.
The lens incorporates an ultra-sonic motor for fast and silent autofocus, ensuring that you can capture candid moments without drawing attention to your camera operations—a crucial factor in event photography.
With a combination of elements such as aspherical and UD lenses, the optical design minimizes aberrations and distortions, ensuring that images are sharp and clear, even at the widest aperture settings, making it suitable for diverse lighting conditions.
The RF 85mm f/1.2 lens has exceptional low-light performance due to its wide aperture.
This means you can achieve high-quality images even in dimly lit environments commonly found at live shows or gatherings.
The lens has a weather-sealed construction, providing protection against dust and moisture, making it more reliable in unpredictable conditions often encountered during outdoor events or in crowded venues.
Bokeh, or the aesthetic quality of the blur in the out-of-focus areas of an image, is notably better in the RF 85mm f/1.2 due to its 9-blade circular diaphragm, which helps create a more pleasing and smooth background effect that enhances the overall composition.
The RF 85mm has a minimum focusing distance of 0.85m (approximately 2.79 feet), allowing for closer close-ups of subjects while still being distant enough to maintain context in images, especially important for capturing emotions during live events.
Canon's lens design includes a special DS coating for certain variants, which reduces ghosting and flaring, offering clearer images under challenging light sources like stage lights or reflections.
The lens's effective image stabilization performance (if applicable) further enhances its utility during fast-paced events, enabling users to shoot handheld with greater confidence to avoid motion blur.
Utilizing Advanced Lens Micro Adjustment may assist in optimizing autofocus performance, especially beneficial in capturing quick-moving subjects at live events while ensuring sharp focus.
The lens's large front element can be demanding on filters; an understanding of optical physics can help you choose between polarizing or ND filters, which can significantly impact the quality of images when shooting video or stills during live events.
The concept of diffraction is relevant at smaller apertures; while f/1.2 provides incredible sharpness, when stopping down too much beyond f/8, some loss of sharpness can occur, which is noteworthy for photographers who utilize a range of aperture settings.
Recognizing the importance of white balance in artificial lighting environments is crucial as mixed lighting sources can result in color casts, requiring adjustments either in-camera or in post-processing to maintain accurate skin tones and colors.
Advanced autofocus systems like Dual Pixel CMOS AF allow for precise tracking of subjects, particularly useful in dynamic live environments where action and subject movement can be unpredictable.
Incorporating flash or off-camera lighting can complement the lens's capabilities, allowing for balanced exposure during evening events while preserving the natural aesthetic made possible by the lens's depth of field characteristics.
Consistent practice and experimentation with various time exposures can lead to creative effects like light trails or blurring movements, capitalizing on the lens’s unique abilities.
Knowledge of hyperfocal distance aids in maximizing a lens's depth of field, ensuring that both foreground and background elements become sharp when shooting scenes where maintaining context is essential, particularly profound in live events where storytelling through imagery is key.
