It utilizes Super ED glass with multi‐coating to reduce flare and ghosting. The Sony SEL90M28G FE does not specify focal length or aperture in the provided data but includes a 12 pin Communication System. Corner to corner sharpness is noted for the Canon RF35mm F1.8 is Macro STM via Advanced Spherical elements.

Macro Capabilities

Macro photography performance is a key differentiator. The Canon RF35mm F1.8 is Macro STM offers a Maximum Magnification ratio of 1.0x, allowing for life-size reproduction of subjects. The Sony SEL90M28G FE provides a 0.5x Magnification Ratio. While both allow for close-up work, the 1.0x capability provides greater detail for small subjects. The angle of view for the Canon RF35mm F1.8 is Macro STM is 27 degree (35 mm) and 17 degree (APS-C).

Focus and Stabilization

Focus mechanisms differ in operation and specification. The Sony SEL90M28G FE features Optical Image Stabilization at up to 5 Stops of shake Correction. It also allows Instant manual/auto focus selection via a sliding focus ring according to the feature list associated with the Canon RF35mm F1.8 is Macro STM. The Canon RF35mm F1.8 is Macro STM uses Direct Drive SSM (DDSSM) for quiet, precise focusing. Optical Steady Shot image stabilization is available for handheld shooting on the Canon RF35mm F1.8 is Macro STM.

Mount Compatibility

Compatibility dictates which camera systems can utilize these lenses. The Sony SEL90M28G FE is Compatible with EOS R series cameras and uses a Canon RF mounting type. The Canon RF35mm F1.8 is Macro STM is a perfect match for α7 series, 35mm full-frame E-mount cameras. Users must ensure their camera body matches the specific mount type listed, as cross-compatibility is not indicated in the provided data.
