Frequently Asked Questions
Does the Canon RF 45mm f/1.2 STM have weather sealing?
No, the lens does not include weather sealing. While it feels solidly constructed, it is not protected against dust, rain, or moisture. Take care when shooting outdoors in adverse conditions.
How does the RF 45mm f/1.2 STM autofocus compare to other RF lenses?
Autofocus is adequate for portraits and still-life, but notably slower than lenses using Canon's Nano USM or ring USM motors. Continuous tracking of fast-moving subjects is not a strong point, making it less suitable for sports, action, or quick street moments.
Is this lens sharp at f/1.2?
Center sharpness is acceptable at f/1.2 for portraits and general use, but corners are soft and chromatic aberration is evident. Stopping down to f/1.8 or f/2.8 greatly improves sharpness and overall image quality.
How does 45mm compare to 50mm or 35mm for everyday photography?
45mm sits comfortably between 35mm and 50mm, offering more context than a 50mm but slightly tighter framing than a 35mm. This makes it a versatile choice for travel, street, and everyday shooting, appealing to those wanting balance between subject isolation and environmental storytelling.
Is the bokeh on the RF 45mm f/1.2 STM smooth?
The lens creates significant background blur at f/1.2, but some users notice uneven or 'nervous' bokeh in challenging backgrounds. While attractive for many images, it may not match the creamy, uniform quality of higher-end primes in the same system.
