A new Canon patent application, published on May 29, 2025, offers a peek into some potentially exciting new lenses. It outlines a few optical designs that closely resemble a “70-200mm F4” and an “APS-C 18-50mm F4”, both seemingly inner zoom lenses, meaning their physical length stays constant while zooming.

Patent Overview

• Publication Number: P2025082363
• Publication Date: 2025-05-29
• Title: Zoom Lens and Imaging Device
• Filing Date: 2023-11-17
• Applicant: Canon Inc. (ID: 000001007)
• Summary: The patent describes a compact, lightweight, positive-lead-type zoom lens design, optimized to correct various aberrations even at longer telephoto focal lengths.

Example Designs

Example 1 (Likely full-frame 70-200mm F4)

• Focal Length: 73.68–194.48mm
• Aperture: F4.10
• Half Angle of View: 16.36°–6.35°
• Image Height: 21.64mm
• Total Length: 198.01mm
• Back Focus: 49.13–65.78mm

Example 2 (Likely APS-C 18-50mm F4)

• Focal Length: 18.54–52.02mm
• Aperture: F4.10
• Half Angle of View: 33.06°–14.50°
• Image Height: 13.66mm
• Total Length: 130.47mm
• Back Focus: 14.72mm (constant)

Both examples maintain a consistent lens length while zooming, which is classic inner zoom behavior. This could be a move targeting video shooters, especially given the growing demand for compact, stable optics. It’s also possible this research influenced the development of lenses like the RF-S 14-30mm F4-6.3 IS STM PZ, which was also patented around the same timeframe.

So, is Canon working on an inner zoom 70-200mm F4? Technically, the RF70-200mm F4 L IS USM already exists, so launching another F4 zoom in the same range might seem redundant. But with the newer RF70-200mm F2.8 L IS USM Z in the mix, maybe we’re looking at a slimmed-down F4 version of that. It wouldn’t be out of character for Canon to double down if they see a niche worth filling.

Canon has quietly registered two unreleased cameras with model numbers DS126916 and ID0184 with an overseas certification body. Naturally, speculation is swirling: are these the long-rumored EOS R6 Mark III or EOS R7 Mark II?

What We Know So Far

• DS126916 has appeared alongside camera ID 0184, both supporting dual-band Wi-Fi (2.4GHz & 5.1GHz) and Bluetooth.
• Canon’s previous registrations show a clear pattern:
  • DS126922 – EOS R5 Mark II (Wi-Fi 6 & Bluetooth)
  • DS126928 – EOS R1 (Wi-Fi 6 & Bluetooth)
  • DS126941 – EOS R50 V (Wi-Fi 5 & Bluetooth)
  • DS126904 – PowerShot V1 (Wi-Fi 5 & Bluetooth)
  • ID174 – Unknown, Wi-Fi 5
  • ID179 – Unknown, Wi-Fi 5

The “DS” prefix typically indicates still digital cameras, while “ID” models are often part of the Cinema EOS lineup.

Given this naming trend and the wireless capabilities, it’s a safe bet that DS126916 is a new stills camera, possibly the R6 III or R7 II, while ID0184 could belong to Canon’s cinema range.

All signs point to an upcoming announcement. Whether the rumors match reality is yet to be seen – but something new is definitely on the horizon.

More murmurings from the interweb of rumor mills. Here is a set of fresh Canon rumors.

TL;DR:
Canon’s teasing us with fancy lenses, delayed cameras, mystery models, and a retro throwback. No one knows what’s coming when, but it’ll be shiny, pricey, and probably require a firmware update within the first week. Classic Canon.

---

Canon kicked off 2025 like a kid tossing confetti with the EOS R50 V, the RF-S 14-30mm f/4-6.3 IS STM PZ, and the RF 20mm f/1.4L VCM – the latter being their widest f/1.4 ever. A bold start. But of course, the real fun is just beginning.

More announcements are expected before July (maybe), and again in late August or September (possibly), though Canon’s calendar remains as cryptic as ever.

EOS R7 Mark II

Expected around late August. It’s moving “up-market” – Canon-speak for “more expensive” – and clearly aimed at wildlife and sports shooters who’d like to avoid mortgaging their house for full-frame gear. High-end RF-S zooms might show up too, if Canon feels generous. See here for all EOS R7 Mark II rumors.

EOS R6 Mark III

Still MIA. People thought it might appear in May, but alas. Rumor has it there’s a hiccup with the LP-E6P battery — because what’s a Canon launch without a battery-induced delay? Forum threads are already lighting up, and we’ll hear more once the smoke clears.

Full-Frame “V” Camera

Canon seems to be cooking up a full-frame “V” camera – think PowerShot V1 and EOS R50 V, but beefier. Most signs point to an R6 Mark III base. This might be Canon’s way of saying goodbye to the EOS R5 C, without actually saying goodbye. Oh, and an R7 V? It was a thing… maybe still is… but probably isn’t. Rumors are so ephemeral ;-)

EOS R10 & Others

A new APS-C camera line is expected, though what or when is anyone’s guess. The R10 could use a facelift — it’s been sitting unchanged since 2022. Later this year, we might get a longer zoom PowerShot V (V3 perhaps), and Canon may dust off the “G” series, or whatever it’ll be called now.

Also, word on the street: a retro-style ILC is coming to celebrate 50 years of the AE-1. Expect that in late 2025 or early 2026 — because nostalgia always sells.

As always, keep the salt available.

Some news from the interweb of eager rumor mills. The Canon EOS R7 Mark II is in the spotlight (again).

Canon’s once-glorious 7D line – the go-to for wildlife photographers who wanted a “diet 1D” – might be soon released in a new iteration as the EOS R7 Mark II. The rumor mill is spinning up claims that this new body could be a “baby R1,” which sounds adorable until you remember Canon isn’t exactly in the habit of handing out pro features to the masses.

So what’s the buzz?

Sensor Drama: There’s a tug-of-war between fantasy and feasibility. A stacked 40MP APS-C sensor would make sense if Canon were in a particularly generous mood – which they’re not. The safe bet is a stacked, BSI 32.5MP sensor: enough resolution to keep bird nerds happy, but with faster readouts to finally stop those nasty rolling shutter gremlins.

Speed & Buffer: 30-40fps bursts sound great until your buffer throws in the towel after a second. Canon might fix that with better memory and CFexpress Type B support. Might. Autofocus will also supposedly get a brain upgrade with AI-driven subject tracking – because it’s 2025 and we’re all legally required to say “AI” at least twice per paragraph.

Video Specs: No, you’re not getting 8K or Canon Log 2. That’s reserved for the adults over in R5 Land. Expect a healthy 4K60p from 7K oversampling, maybe 4K120p (cropped), and some very polite 10-bit color. No active cooling, because again, you’re not paying R5 prices.

Ergonomics & Build: Canon’s likely to steal some hand-me-downs from the R5 II – nicer grip, tweaked controls, hopefully a joystick that doesn’t feel like a wobbly Lego. Better EVF, brighter LCD, maybe even a battery grip that does something useful.

Price & Release: Expect to pay more than the original R7’s $1,499 – think sub-$2K, but not by much. Release window? Somewhere between “Q3” and “whenever Canon feels like it.”

In short: the R7 Mark II is shaping up to be a solid middle child – not quite flagship, not quite entry-level, but with just enough sparkle to keep you refreshing rumor blogs. That’s if the rumors hold up to reality. Time will tell.
