Canon RF 35mm F1.8 Macro IS STM Lens: Review and Sample Images

The Canon RF 35mm f/1.8 Macro is a lightweight and affordable option that stands out for its close minimum focusing distance, allowing for a maximum image magnification of 1:2. A valuable alternative to Canon’s L-series lenses, it offers advanced features such as image stabilization and manual control, though with some compromises in build quality.

Build Quality and Design

Although the Canon RF 35mm f/1.8 Macro is a relatively affordable lens, the quality of the plastic used in the main barrel is comparable to that of more expensive lenses, such as the Canon 15-35mm f/2.8 L. However, it lacks weather sealing and the front element does not feature a fluorine coating, which could be problematic in harsh conditions. Additionally, its extending barrel design may allow dust to enter, potentially affecting its long-term durability.

Optical Performance

• Distortion: Low.
• Vignetting: High at wide apertures, especially at f/1.8, but improves significantly by f/2.8.
• Lateral Chromatic Aberration: Very low, almost imperceptible.
• Sharpness: Excellent center sharpness from f/2.8, peaking at f/4 and f/5.6. Corners are weaker at f/1.8 but improve when stopping down.
• Coma: Noticeable at f/1.8, but improves significantly by f/2.8.
• Bokeh: Pleasant at macro distances, but slightly nervous at longer distances, with noticeable longitudinal chromatic aberration at wide apertures.
• Halos: Decent control of halos, though some issues may appear at close focusing distances.

Focusing

The lens focuses accurately and consistently, but it may struggle to find focus in low light conditions. The STM motor is relatively noisy, which can be a drawback when recording video with an on-camera microphone. The minimum focusing distance is excellent and allows for a magnification of 0.5× (1:2), although the 35mm focal length may require getting quite close to the subject, which can startle animals or cast shadows.

Usability and versatility

The lens includes advanced features such as image stabilization and extensive manual controls, which is unusual in this price range. The external focus design with barrel extension can be a drawback in terms of protection and durability. Image stabilization allows handheld shots in low-light conditions with shutter speeds from 1/6 to 1/10 seconds.

Additional features

• Lens hood not included: The absence of a lens hood is a notable omission, especially considering the price of the original.
• Control rings: Includes a focus ring and a customizable ring, with switches for AF/MF and image stabilization.
• Halos at close distances: Presence of halo lines in out-of-focus areas, which may be an interesting visual characteristic for some users.
