Canon R7 Mark II Rumors: A New RF-S 15-70mm f/4 Kit Lens Coming?
A new rumor has surfaced that the R7 Mark II will also come with a new RF-S kit zoom lens, rumored to be a 15-70mm. Not much more is known, except that it's thought that it would be a constant F/4 aperture lens and be released with the R7 Mark II.
Canon has in the past applied for a patent application for an APS-C 15-70mm F/4 (Japan Patent Number 7770854), so we'll talk about this for a bit. It will give us an idea of what Canon is perhaps thinking about.

A few things jump out at me. This is quite a compact lens for the focal range, having a minimum size of around 90mm. The backfocus distance is around 10.46mm, which means that the lens sits inside the lens mount around 10mm, which is a significant ingress into the mount. The lens also employs a wide-angle stretching, which would seem to fit in with a simple RF-S non-L design.
Will Canon make this lens?
Would Canon do such a lens? Quite possibly, but I would be the first person to say that while the focal length is great, the optical quality will take second place to zoom range and price. I'd expect the MTF to look something similar to that of the RF 24-105mm F4-7.1mm, but with a smaller image circle. It's also very unlikely that a 4.5-year-old patent application will actually become the lens.
The EF-S 17-55mm was a decent lens for the EF-S system, but optically, it's much more difficult to extend the zoom range. Quite personally, I would want the 15-45mm focal length returned to Canon's list of lenses, which translates to a more realistic 24-70mm, and is quite able to deliver far superior image quality than an extended 4.5x zoom range lens is capable of delivering.
So while an RF-S 15-70mm sounds pretty cool, and I'm sure it's great for clickbait, I'd much rather have a more realistic kit lens for the R7 Mark II.
Then again, Canon also was the one that thought the Canon EF 28-135mm was a great lens to pair up with the 7D.
