Sigma Might Make An Important Canon RF Mount Related Announcement Soon

Canon Rf Mount

Sigma might be set to soon announce something important about Canon RF mount lenses (i.e. for the Canon EOS R system).

A new rumor suggests, coming from various sources, that Sigma will soon announce their long term plans concerning RF mount lenses. Moreover, it seems that the development and upcoming release of the Canon EOS R5 might have sped up Sigma’s plans to have RF mount lenses available by 2021.

The interesting part in the rumor is that Sigma will not convert existing ART lineup lenses to the RF mount but come up with an exclusive RF mount lens lineup. And that, in our opinion, is very interesting.

Let’s hope Sigma really comes up with an exciting RF mount lens lineup but we recommend you take this rumor with a grain of salt for the time being.

More RF mount information is listed here.

More to come, stay tuned.

Review: Sigma 16mm & 30mm & 56mm f/1.4 DC DN For Canon EOS M

Sigma 16mm

A review for those interested in the Canon EOS M system: Sigma 16mm, 30mm, and 56mm.

Photography Blog posted their review of three Sigma prime lenses, the Sigma 16mm f/1.4 DC DN Contemporary, Sigma 30mm f/1.4 DC DN Contemporary, and Sigma 56mm f/1.4 DC DN Contemporary lenses for the EF-M mount.

From their conclusion:

While the 56mm is undoubtedly our pick of the bunch, all three would make great additions to the rather threadbare camera bag of a Canon EOS M shooter.

This is especially true for the wide-angle Sigma 16mm F1.4 DC DN C and the short-telephoto Sigma 85mm F1.4 DC DN C, as there are no direct rivals in the Canon range […]

It’s a tougher sell for the Sigma 30mm F1.4 DC DN C because of the EF-M 32mm f/1.4 STM, but even then the Sigma is pretty compelling simply because of its price […]

So, if you’re a frustrated Canon EOS M user who has outgrown their kit zoom and doesn’t want to adapt a Canon DSLR lens, the introduction of three well-built, high-quality, ultra-fast Sigma lenses in the native EF-M will be music to your ears.
