Canon Patent Application: APS-C 15-45mm

[Canon Rumors]

One of the disappointments for me with the RF-S system is the normal kit zoom range from 18-45 instead of 15-45mm. In this patent application, Canon sets out to create a 15-45mm that hopefully isn’t plagued with the same quality assurance issues as its older EF-M brother. I swear I went through 5 copies until

76.36 is almost exactly 3 inches.
79.34 is a little longer but it retracts to 71.19 anyway.
I am assuming that it will be in the most compact position when stored.
The RF-S 18-45 is much smaller than a kit lens needs to be.
They could have just gone with 15-45 but now that we have the RF-S 10-18, 18-45 makes sense.
Nikon has the DX 16-50 on a 1.5x crop.
That alone is good enough reason for Canon to make an RF-S 15-45.

15-45 is better than 18-45, but for me the question is, are there going to be some good RF-s lenses? Something like EF-s 60mm macro or EF-s 15-85 (maybe lighter)? Now it's just a typical Canon galore of 18-whatever f/too-high. It's a pity since EOS R7 is a nice body.

I don‘t think, that the 18-45 is the typical companion lens for a semi-pro body like an R7.
Except for just one use case:
Being small and light for travel or else.
In that case it serves that purpose well, doesn‘t it?

keep in mind that would also include the 20mm of the sensor to flange, so the lens itself is 55mm in length.

I found the 15-45 to be a nice walkaround on the M's once I found a good copy. I really dont' want to go back to 18mm

The 15-45 is one of those lenses where DPP4+DLO makes a big difference. I wonder if DxO with the ‘new’ demosaic algo used for deepprimeXD would do similar good job nowadays.

I still prefer the 11-22 over the 15-45, though, the extra width is great for getting more environment into indoor shots, like in cramped cafes.

Something like EF-s 60mm macro

Almost every RF-S lens so far has macro capabilities.
I am not sure that I see the need for a dedicated macro lens.
Although I do expect a few RF-S portrait prime lenses.
Even though those are not as necessary with the bargain EF f/1.8 prime lenses.

I agree it's not necessary, but there seem to be enough people with complaints about the 1.8 primes that Canon could probably sell rf-s primes -assuming they can address those complaints without price increase.

More like “macro”, I personally set the bar at 1:1 or better, lens manufacturers have much lower standards, like 1:3 for slapping on a ‘macro’ label.

Has Canon ever made a 1:1 APS-C lens?

Has Canon ever made a 1:1 APS-C lens?

The EF-s 60mm can do 1:1 and the EF-M 28mm can do 1.2:1. The EF-S 35mm that looks like a copy of the EF-M 28mm also does 1:1.

So at least 3 APS-C specific 1:1 or better lenses. The 28 and 35 even have a built-in ring light, which I’d like to see in a future RF macro like the MP-R.
