Patent: Canon RF 17-70mm f/3.5-5.6

[Canon Rumors]

Canon News has uncovered a patent for a new RF mount optical formula, this patent shows an RF 17-70mm f/3.5-5.6 in various forms. This looks like some kind of wide kit style lens because of the variable aperture.
Below are the three embodiments:

17-70 f3.5-5.6 is an ideal FF compatible aps-c lens for a mirrorless 7d ish camera.

 

[Kit.]

Not as wide as 15-85 - not ideal.

Good as a FF kit lens, though.

17-70 f3.5-5.6 is an ideal FF compatible aps-c lens for a mirrorless 7d ish camera.

Yes, an ideal focal length for APS-C, or a nice ultra-wide zoom for FF.

Also, with the cropped 4K on the R, it would be a nice lens for video.

I’ve said it before and I’ll say it again. It is one heck of a fun time to be a camera nerd.

 

[Del Paso]

Some whiners ("only big and heavy lenses nobody wants to buy") should now at least be satisfied...

True, but that's not a standard kit lens on any of the 000x or 00x models. The normal kit lenses are 18-55 and 18-135. In the past they have started at 17, but the 15-85 was always a premium upgrade.

I suspect the primary reason it's not 18-55 is that it cost the same to make it slightly wider and slightly longer, and 70mm rolls right into a 70-300 (or 70-200 if it's an upsell). This just cements in my mind that aps-c will come to RF. We will eventually see RF rebels, and probably even a full frame rebel at a 999 price point, even cheaper "street" price. I think the only thing that will NOT happen is RF-S.

I'm back from a vacancy changing several times the Wide and standard zoom.
This is the solution for travellers.

PS report for flamers:
In a group (general tourist) we have
1 5D4
1 6D
3 rebels
1 nikon reflex aps-c
1 fuji ML
1 sony 6x00

So an aps-c R is confirmed then. I guess it won't take long for it be announced after the 90d. But then again I don't understand why the 90d release oin that case? Especially since the 90d seems more like a replacement of 80d than 7dmii?

It's just a patent. Patents don't confirm anything, so I wouldn't get my hopes up just yet.

Can't be true:
There must have been at least 90% of Wonderful Sonies according to Youtube .

It would make no sense to get s FF superwide and waste it with a crop sensor. On full frame such superwide to short tele would be nice.

 

[timmy_650]

That is like my dream walk around around lens. I can shoot landscapes well and get good pictures of my daughter as well with out switching lenses.

Definitely a full-frame lens for full-frame camera, I think (as do some of the folks in prior answers) that one needs to re-think zoom lens strategies with the potential of a new mount. I am leaving tomorrow for a trip to south America, wanting to walk around with light(er) gear than my usual 11-24, 24-105 and 100-400, and using current lenses that I have: 16-35 L IS, 24-105 and either the 70-200 L 4.0 IS or 70-300 DO. Note the overlaps, not always a bad thing but I have 2 bodies for 3 lenses for this use case. Instead, with new RF gear I could have a 17-70 and a 70-200 (or 70-300, sure bet they will offer that at some point in time), so with 2 bodies I do not need to change lenses. Brilliant!
I see assumptions of this not being an L lens because of the variable aperture, but the EF 100-400 and 70-300 L are variable aperture, so let's not jump to conclusions.

So an aps-c R is confirmed then.

Only in your mind.

I think the only thing that will NOT happen is RF-S.

While it's not a standard APS-C kit lens, even though it would be much better to have an RF-S 17-70mm, it would to the job in a pinch if Canon wanted to simply release an APS-C camera into the wild with no supporting RF-S lenses. It's one of the few full frame lenses that I could see fitting into both full frame and aps-c, as a kit lens for both sensor sizes. the EOS RP could use it as a sweet kit lens, and so could an APS-C RF camera.

Also, this is the second time we've seen 17-70mm in patent applications, which makes it a bit more likely it's going to happen.

 

[Philrp]

Oh man that will fit so nicely on my APS-C equipped EOS R.

Yippy!!!!

 

[twoheadedboy]

This would be perfect, because I could carry this and a 70 - 200 plus a fixed lens or teleconverter and have a very reasonable bag.

Right now I carry a 16 - 35 + 24 - 105 f/4's + fixed (28 or 85 f/1.4), or 16 - 35 + 70 - 200 f/2.8 + 50 f/1.2 or TC's. None of those configurations are as ideal as this would be.

 

[Loswr]

While it's not a standard APS-C kit lens,

It has a FF image circle. Think of it as a 17-40 combined with a 24-70, with a variable aperture to keep size/cost down as a non-L lens. Honestly, I think it would be an excellent standard zoom for the EOS RP.

 

[criscokkat]

i don’t know why so many people are so defensive by the prospect of canon selling an r mount aps c camera. This lens patent works for both.

As I recall, Canon said they planned to sell more full frame lenses, they picked their words carefully and never said systems or bodies when talking about the RF mount.
