The EF 100mm f/2 was and is an underrated gem. I still use mine on the R5 II and, as noted here, it does have flaws: CA, some fringing, and a long minimum focus distance among them. But it is predictable, effortless to handle, and has a delightful rendering.
One reason I never bought the optically fabulous RF 85mm f/1.2L was my hope that Canon would eventually produce a modern RF 100mm f/1.4L.
I had hoped for a lens inspired by the truly exceptional RF 135mm f/1.8L — a masterpiece that combines near-perfect image quality, confident autofocus, and excellent handling in a way few lenses ever have.
I’m not sure a VCM design philosophy is exactly what I had in mind for a 100mm portrait lens, but kudos to Canon anyway. They have shown a thoughtful commitment to the hybrid prime lineup, and many photographers clearly love these lenses. We have also heard an awful lot recently about new zooms.
Still, is it too much to ask for a few more stills-first halo primes?
Where are the RF 50mm f/1.2L II and RF 85mm f/1.2L II that apply the lessons of the RF 135mm to improve handling and autofocus while preserving their legendary rendering?
Where are the RF 24mm and 35mm f/1.2L lenses?
Those feel like surprisingly large gaps in an otherwise great system. Perhaps Canon has a surprise up its sleeve and another line of stills-focused halo primes is still to come.
Hope springs eternal.
Until then, I’m still shooting the heck out of my beloved EF 100 and my newest friend, the RF 135.
