Macro Photography with the Canon RF 35mm F1.8 Lens: Macro review
Exploring Macro Photography
Macro photography involves capturing extreme close-up photos of subjects like insects, flowers, textures, products and more. Special macro lenses allow focusing at very short distances to magnify tiny details. Common magnification ratios are 1:1 (life size), 1:2 (half life size), and 1:10 (10 times life size).
The Canon RF 35mm lens has 0.5x magnification at minimum focus distance, allowing it to focus much closer than standard lenses. This opens up creative options for macro work.
Performance of the Canon RF 35mm F1.8 in Macro Photography
With its built-in Macro mode, the RF 35mm f/1.8 autofocuses quickly on close-up subjects and automatically adjusts focus range for optimal macro results. The wide f/1.8 aperture helps create shallow depth of field to isolate details from the background.
Image quality remains sharp across the frame when shooting macro subjects, even at f/1.8. The 7 rounded aperture blades produce pleasing out-of-focus bokeh for artistic background blur in macro images.
The 0.5x magnification provides solid macro capabilities, though more specialized macro lenses offer higher 1:1 magnification for the most extreme close focusing ability. But the Canon RF 35mm still provides respectable results for food, products, flower and insect photography.
Sample Images of Macro Shots
- Extreme close-up of a ladybug showing all the minute details and textures
- Top-down photo of a plate of food that fills the entire frame
- Abstract image of water droplets on a leaf with blurred green background
- Bright orange flower photographed from the side with soft bokeh
- Stack of colorful macarons with Incredible detail visible on the meringue cookies
Image Quality and Performance with this focal length
Sharpness and Clarity
The Canon RF 35mm F1.8 delivers impressive sharpness and clarity across the frame, even when shooting wide open at f/1.8. Fine details are maintained and images have a crisp quality straight from the lens. Stopping down just slightly increases definition, with peak sharpness around f/4.
Sharpness remains consistent whether shooting portraits, landscapes or macro subjects. The advanced optical design and use of a molded glass aspherical lens element reduce aberrations for excellent resolving power.
Color Rendering
Colors are rendered accurately and attractively by the Canon RF 35mm lens. For portraits and people photography, skin tones look natural yet vivid. Landscape images showcase lush vivid greens and blues.
Bokeh highlights take on pleasing colors without harsh fringing or aberrations around edges. Overall the lens produces images with great color rendering that need little post processing.
Bokeh and Background Blur
The bright f/1.8 aperture allows for smooth, creamy out-of-focus bokeh in both portraits and macro shots. The 7 rounded aperture blades produce pleasing blob-like bokeh balls in defocused highlights.
At wider apertures, background blur is nicely softened without being too busy. Stopping down creates greater depth of field with more defined bokeh circles. Overall the quality of bokeh matches what you’d expect from a fine prime lens.
Focusing and Autofocus Performance
STM (Stepping Motor) Technology
Canon’s STM autofocus motors use a stepping action for smooth and quiet focusing that is well-suited for video recording. Focus transitions happen fluidly without the noise or vibration of other autofocus motors.
On the RF 35mm F1.8 lens, STM AF provides fast and silent performance whether shooting photos or videos. The autofocus is discreet enough for events, weddings or other sensitive environments.
Speed and Accuracy of Autofocus
Autofocus speed is snappy and accurate in a variety of conditions. In good light, AF locks on instantly with precise focus. The lens continues to focus quickly in lower light conditions where some lenses begin to hunt.
Accuracy remains reliable when shooting moving subjects like candid portraits, street scenes or active kids and pets. One-shot AF efficiently tracks subjects as they move through the frame.
Low-Light Focusing
Low-light autofocus performance also impresses thanks to the bright f/1.8 maximum aperture. The lens can continue to quickly lock focus in dim indoor settings, at dusk, or at night. This allows handheld shooting in light as low as EV -5 when paired with advanced EOS R bodies.
