For years, us Canon RF shooters had a bit of a… problem. We had the glorious EOS R bodies—the R7, R10, R50, and the R5/R6 powerhouse series—but when it came to filling our bags with quality glass, our wallets often felt the pinch. The choice was often stark: shell out big bucks for native RF glass, or stick to vintage EF lenses with an adapter (a great, but often bulky, solution).
But that’s all changed. The wait is over. The seismic shift we’ve been dreaming of has finally arrived.
Sigma is officially in the RF-mount game
For hobbyist and developing photographers, this isn’t just news; it’s a revolution. It’s the permission slip we’ve all been waiting for to expand our creative potential.
Why Sigma and Why Now?
Let’s face it: we love our craft. We take pride in our work. But not everyone has the budget of a full-time pro who can expense their top-tier gear. We demand performance, but we also appreciate value. This is precisely the space Sigma excels in.
For the uninitiated, Sigma (the largest independent lens manufacturer) has spent the last decade earning a formidable reputation for their “Art” series and “Contemporary” lines. They became known for delivering optics that frequently matched—and sometimes even outperformed—first-party manufacturers, but at a price point that made your accountant smile.
Until recently, they couldn’t officially make lenses for Canon’s native RF mount due to licensing. Canon’s RF mirrorless system is spectacular, but the native RF lens lineup, while fantastic, has been expensive.
Sigma’s entry changes the equation entirely. Now, anyone shooting on an EOS R7 or R10 can unlock a whole new level of creative expression without compromise. You are no longer choosing between “affordable” and “sharp.” Sigma gives you both.
Enter the RF Lineup
Henry’s Camera, always a reliable spot for Canadian photographers, is among the first retailers to stock these beauties. Sigma’s first wave of RF lenses focused heavily on the incredible performance of APS-C (cropped sensor) bodies like the Canon R7, R10, and R50.
Why is this so exciting? Because crop-sensor cameras give you extra “reach,” which is amazing for wildlife and sports, but finding high-quality, wide-aperture lenses specifically designed for that smaller sensor has historically been tough. Sigma has delivered exactly what that community has been begging for.
Here are the 8 Sigma RF lenses now available (all designed for APS-C R-series bodies), their standout features, and what they are perfect for.
The Sigma RF Prime Collection
