Even if you own a Canon R-series mirrorless camera, some lenses on the DSLR list may hold preferable choices until Canon fills out the RF lens lineup.

About Canon Macro Lenses

If your current lens will not focus close enough to make a subject larger in the frame, it is time to get a macro lens. Macro lenses are very fun to use, macro subjects are everywhere, and the unusually close look at these typically-small subjects can be beautiful and intriguing. The results of macro photography are very fun to share.

While many lenses have "macro" in their names, that word does not get my attention until the specifications reveal that it has a 1:1 or 1x maximum magnification ratio. This ratio means that the subject will render at life-size on the camera's sensor. A 20mm-wide subject will render across 20mm of the sensor, 20mm is a significant portion of the imaging sensor width, and the subject will be made HUGE on your large monitor.

There are always subjects available for macro photography. And bringing home flowers for your wife (and to photograph of course) can even strengthen your marriage. :)

Deciding which focal length will work best for your needs is, as usual, part of the lens selection process. Longer focal length macro lenses will give you more working distance at 1:1 - this reduces the tendency of live subjects to fly or crawl away. Longer focal length lenses also have narrower angles of view, which means that there is less background to incorporate into an attractive-looking image. And that background will be more-diffusely blurred, as shown below.

Focal Length Background Blur Comparison

The subject in the images above are identically framed using the same camera, the same aperture setting (f/16), and they have identical subject to background distances. As a rule, the same framing and the same aperture results in the same Depth of Field (DOF) until focus distances approach the hyper-focal distance. But, perspective, compression, and angle of view are very different between these sample photos. The 180mm lens shows only a small physical area of the subject's background that is enlarged, magnifying the blur. Background elements in the 60mm picture appear to be more in focus. However, they just about as blurred though these elements are far less magnified. There are also more background elements showing because of the 60mm angle of view. The result is a less diffusely-blurred background.

If you are using a backdrop (such as rolled paper), the background blur aspect will not likely be important to you.

There are downsides to the longer focal length macro lenses, including larger size, heavier weight, and faster shutter speeds required for handholding. Longer focal length macro lenses typically cost more than the shorter counterparts.

I tend to prefer longer focal length macro lens result best, but find myself using the about-100mm focal length the most.

It is essential to understand that the depth of field at 1:1 macro focusing distances is very shallow. Here is an aperture comparison as illustrated by a 180mm lens:

Macro Lens Aperture Comparison

Narrow apertures are called on frequently for macro photography, and narrow apertures mean longer shutter speeds. Long shutter speeds will often require image stabilization, a tripod, or flash to stop the camera motion blur. For macro use, the maximum aperture of a macro lens is not often essential to me as all lenses have my most-used f/8 through f/16 aperture openings. That said, a wide aperture makes creative blurs easier, as shown by the 100mm f/2.8 example below.

Macro Wide Aperture Sample Picture

Unleash your creativity. Or, move farther from your subject, and a wide aperture can be extremely useful for keeping a distracting background in a blurred state. Most macro lenses have great general-use telephoto lens utility, including for portrait photography.

While autofocus is nice to have in a macro lens, I often use manual focus for critical focus accuracy at close focusing distances. But as with a wide aperture, a good-performing autofocus system can be beneficial in some macro photography uses and more often for other macro lens uses.

The Best Canon Mirrorless Camera Macro Lenses

Canon RF 85mm F2 Macro IS STM Lens Buy  ► Rent  ►

1. Canon RF 85mm F2 Macro IS STM Lens

Economical, Compact, Light, Good Product Image and Portrait Focal Length, Image Stabilization, Only 0.5x Macro Capablities

I like the 85mm focal length for macro photography, but the 0.5x native macro capabilities falls short of my first choice preference of a full 1.0x magnification. Extension tubes will close that gap, and otherwise, this compact and affordable lens is very useful.

 

Canon RF 35mm f/1.8mm f/1.8 IS STM Macro Lens Buy  ► Rent  ►

2. Canon RF 35mm f/1.8mm f/1.8 IS STM Macro Lens

Economical, Compact, Light, Good General-Purpose Focal Length, Image Stabilization, Only 0.5x Macro Capablities

As with the RF 85mm F2 IS Macro lens, the RF 35mm F1.8 IS Macro lens reaches half way to the 1.0x magnification capability (with an extension tube). The 35mm focal length is relatively wide for a macro lens, with different perspectives able to be created. Again, this lens is compact, light, and affordable.
