Canon RF 100mm f/2.8L Macro IS USM (RF mount)

4.7

$1,149as of Jun 7

The Canon RF 100mm f/2.8L Macro IS USM is the best macro lens overall for Canon RF shooters, pairing class-leading 1.4:1 magnification with reference-grade sharpness. Digital Camera World gave it 5 stars ('a stunning macro lens'), Amateur Photographer called it 'a sensational optic,' and OpticalLimits scored it 8.5/10. The price and the niche SA ring are the only real caveats.

Strengths

— Greater-than-life-size 1.4:1 maximum magnification
— Tack-sharp across the frame from f/2.8 on high-resolution bodies
— Up to 5 stops of in-lens IS, more with IBIS-equipped bodies

Watch-outs

— Expensive, like most L-series glass
— The SA control ring is a feature many will pay for but rarely use
— Slight focus shift (RSA) when stopping down at very close distances

Ranked #4 in Best Macro Lenses

Tamron 90mm f/2.8 Di III Macro VXD (Sony E / Nikon Z)

4.5

$699as of Jun 7

The Tamron 90mm f/2.8 Di III Macro VXD is the value champion of the macro field, reviving Tamron's legendary 90mm macro for mirrorless. PetaPixel called it 'sharp and capable for the value-minded photographer,' and Cameralabs rated it Highly Recommended. It delivers first-party-grade 1:1 sharpness and fast VXD autofocus for hundreds less than Sony or Nikon glass; the trade-off is no in-lens stabilization.

Strengths

— Excellent value, considerably cheaper than first-party macros
— Incredibly sharp in the center at f/2.8 with strong corners
— Fast, accurate VXD linear-motor autofocus

Watch-outs

— No optical image stabilization (relies on in-body IBIS)
— Stops at 1:1, not the 1.4:1 of the Canon and Sony flagships
— Roughly 4-inch working distance is shorter than the 105mm options

How they stack up

Canon RF 100mm f/2.8L Macro IS USM (RF mount)

The Canon RF 100mm matches the Sony FE 100mm f/2.8 Macro GM OSS for class-leading 1.4:1 magnification, going beyond the strict 1:1 of the Nikon Z MC 105mm, Tamron 90mm and Sigma 105mm, and adds the SA control ring none of the others offer.

Tamron 90mm f/2.8 Di III Macro VXD (Sony E / Nikon Z)

The Tamron 90mm undercuts the first-party Sony FE 100mm GM and Nikon Z MC 105mm on price while delivering comparable 1:1 sharpness, but unlike them and the Canon RF 100mm it has no optical stabilization; like the Sigma 105mm it relies on in-body IBIS.
