Dustin Abbott posted his exhaustive Laowa RF 100mm F2.8 APO 2:1 Macro review. He says:
In conclusion, I’m more positive than ever about the Laowa 100mm F2.8 APO 2:1 Macro in the Canon RF mount. It has the same flaws as before (too short of focus throw, being flare prone), but using the lens on mirrorless really mitigates some of its other shortcomings (manual focus only, no image stabilization) and I’m left with a lens that is generally fun to use and easy to focus. The punchy colors and images in general remind me of much more expensive APO lenses. When used to its strengths, images from this lens really pop.
And, as a macro lens, it’s additional degree of magnification allows you to do things that lesser lenses cannot. It unlocks an extra level of creativity, and that Apochromatic design allows you to shoot shiny metal textures without fear of chromatic aberrations destroying the image.[…] This remains as one of Laowa’s best value lenses, and is certainly a blast to use on a good mirrorless body.
As usual Dustin Abbott’s reviews come with sample images, comparison charts, and all the information you might want to know. Dustin’s reviews are what I look for when I am about to purchase new gear. As usual Dustin Abbott also releases a complete video review. See below.
