Do no miss it.
This is where we will start to expose the deep dishonesty of the rumors sites industry.
They all lie, fabricate rumors, and fool you in every way to get you to click on their f****ing ads.
These are utterly dishonest figures. Let us call them out.

At CP+ 2026, Cosina is displaying a new NOKTON classic 35mm f/1.4 full-frame lens for Canon RF mount.
This large-aperture, compact wide-angle lens adds to Canon’s RF-mount lineup, reviving the character of classic lenses through the refinement of modern optical technology.
Unlike contemporary designs, this performance-driven lens lens intentionally retains aberrations to embody the lens’s character and the beauty of its expression — a nod to vintage glass that many photographers still covet.
Here we have the first images of the new Kase 150mm f/5.6 REFLEX lens. It’s coming in two flavors:
The 150mm f/5.6 Reflex design is a telephoto prime, likely aimed at portrait or telephoto applications. Reflex (mirror) lenses offer a compact form factor but typically have slower apertures and characteristic doughnut-shaped bokeh.

The EOS R6 Mark III has been out since November 2025, and the reviews are starting to roll in. Mobile01 just published their full take (via Asobinet), and it’s pretty glowing — with a couple of caveats.
Sensor & Speed
Video
Build & Ergonomics
Autofocus
Mobile01 calls it “a highly competitive hybrid with few weaknesses” — strong in both stills and video, with real-world improvements that matter. The 7K Open Gate and full-size HDMI alone are significant wins for hybrid shooters.
Pricier than the Mark II at launch — but you’re getting a meaningfully upgraded camera.

Canon just dropped a new patent, and it’s making us raise an eyebrow. Published February 27, 2026 (filed August 2024), the patent describes zoom lenses with apertures ranging from f/1.2 to f/1.4 — using reflective-transmissive (mirror) elements to keep things compact.
The filing (P2026033938) covers several implementations:
Example 2
Example 3
Example 4
Example 5
That’s… extremely short backfocus. Like, “we’re not talking about RF mount” short.
For context, RF-mount lenses need a backfocus of around 20mm+ to clear the mirror. These numbers — 0.40mm and 0.70mm — are barely enough to clear a sensor. This suggests the optical design is intended for:
Not interchangeable lenses. Canon confirmed this in the filing notes: “backfocus is extremely short so this is not intended for interchangeable lens systems.”
Canon previously filed similar patents for prime lenses using the same reflective-transmissive technology — a 24mm f/0.7 and a 12mm f/1.0. Those were weird enough. Now they’re applying the same trick to zooms, going even wider and faster. A 28-45mm f/1.2 zoom would be absolutely enormous if built with conventional optics. The mirror elements fold the light path, dramatically shrinking total length.
Is this coming to an RF-mount lens? Almost certainly not. The backfocus is physically incompatible.
Could this be a hint at future compact camera ambitions? Maybe. The G7 X line is due for a replacement, and a 28-45mm f/1.2 equivalent in a pocketable body would be something to see.
Or maybe Canon just likes filing patents for lenses they’ll never build. We’ve seen stranger things.

Sigma has officially announced the Sigma 15mm f/1.4 DC | Contemporary lens for Canon RF mount, alongside Sony E-mount and Fujifilm X-mount versions.
Sigma 15mm f/1.4 DC | Contemporary is the successor to the Sigma 16mm f/1.4 DC DN | Contemporary, further refining the acclaimed optical performance while achieving remarkable compactness and lightweight design.
