Canon RF 100mm f/2.8L IS Macro Review (great lens with some added weirdness)

RF 100mm F/2.8L Macro IS Review

Here is a new Canon RF 100mm f/2.8L IS Macro Review. The Canon RF 100mm f/2.8L IS Macro is a lens getting many positive reviews. A rather interesting lens for any EOS R owner.

At a glance:

  • RF-Mount Lens/Full-Frame Format
  • 1.4x Magnification with Autofocus
  • Aperture Range: f/2.8 to f/32
  • Minimum Focusing Distance: 10.2″
  • Super Spectra Coating
  • Smooth and Quiet Auto Focus
  • Optical Image Stabilization; Hybrid IS
  • Control Ring for Direct Setting Changes
  • 9-Blade Diaphragm
  • Weather-Sealed Construction

The experts at Optical Limits posted their Canon RF 100mm f/2.8L IS Macro review. From their conclusion:

The Canon RF 100mm f/2.8 L USM macro IS is a great lens with some added weirdness. Optically, it is capable of delivering very sharp images straight from f/2.8 – just as you would expect from a moderately fast macro lens. Image distortions are basically negligible even without correction. Lateral CAs are on the low side as well and can be easily corrected anyway. This can’t be said of the raw vignetting which is comparatively high at f/2.8 so auto-correction should remain activated. The quality of the bokeh is generally pleasing with a smooth background blur and nicely rendered highlights. The foreground blur isn’t ideally rendered but that’s usually of lesser concern. Bokeh lovers may also like the SA feature on the lens but, to be honest, for most of us, it’ll remain an oddity that you have to pay for without using it. Maybe video makers can appreciate it more than photographers. That being said – the massive focus-breathing doesn’t help with videos. A bit concerning are the RSAs when stopping down – focus shifts aren’t helpful at very close focus distances. It’s something to keep in mind when shooting at least.

Chris and Jordan say:

Over a year after it was announced, Chris and Jordan had the chance to play with the Canon RF 100mm F2.8 L IS Macro! Alongside the expected improvements in autofocus speed and optical performance, this lens feature Spherical Aberration Correction, which allows you to change the look of out-of-focus areas. Is this new lens worth the premium price?

Canon Patent: 135mm f/2 1:2 Macro And 200mm f/2.4 1:2 Macro Lenses

Canon Patent

And yet another Canon patent application: 135mm f/2 1:2 Macro And 200mm f/2.4 1:2 Macro Lenses.

Canon patent application 2022-22595 (Japan) discusses optical formulas for two macro lenses: 135mm f/2 1:2 M.

PROBLEM TO BE SOLVED: To provide an optical system capable of expanding a close range in a small size while suppressing the number of focus groups, and an image pickup apparatus having the same.

If the floating focusing method is used to increase the close-up magnification, the number of lenses in each group increases, and it is difficult to drive the focus group at high speed. In the lenses of Patent Document 1 and Patent Document 2, when the number of lenses in the focus group is reduced in order to realize high-speed drive, sufficient aberration performance cannot be obtained because the configuration of each group is not appropriate.

An object of the present invention is to provide an optical system capable of expanding a close range in a small size while suppressing the number of focus groups, and an image pickup apparatus having the same.

Example 1

  • Focal length: 133.0
  • F value: 2.05
  • Half angle of view: 9.24
  • Image height: 21.64
  • Shooting magnification: -0.5

Example 3

  • Focal length: 200.0
  • F value: 2.40
  • Half angle of view: 6.18
  • Image height: 21.64
  • Shooting magnification: -0.5

Example 4

  • Focal length: 199.9
  • F value: 2.80
  • Half angle of view: 6.18
  • Image height: 21.64
  • Shooting magnification: -1.00

Canon Patent: RF 100mm f/2 Macro Lens (EOS R system)

Canon Patent

And yet another Canon patent application for an RF mount lens. A new macro lens might be in the works.

Canon patent application 2022-16822 discusses optical formulas for a RF 100mm f/2 Macro lens.

PROBLEM TO BE SOLVED: To provide an optical system which is small in size, suppresses aberration fluctuation due to focusing, and can obtain high optical performance over an entire object distance from infinity to a close distance, and an image pickup apparatus having the same.

A macro lens whose main purpose is to shoot a short-range object is configured to be capable of shooting from an infinite object having a shooting magnification of 0 times to a short-range object having a shooting magnification of about 1x. desirable. Further, the macro lens is required to have low aberration fluctuation and high optical performance over the entire object distance at the time of focusing, and the focus lens group is small and lightweight in order to perform focusing at high speed. When the inner focus method and the floating method are used, it becomes easy to perform focusing at high speed, reduce aberration fluctuations due to focusing, and obtain high optical performance over all object distances from infinity to close range.

Example 1

  • Focal length: 97.00
  • F value: 2.06
  • Half angle of view: 12.57
  • Image height: 21.64
  • Overall length: 159.46
  • Back focus: 19.70
  • Shooting magnification: -1.0
