There is talk of a Canon RF 20-50mm f/4-5.6 IS STM [CR1]

[Canon Rumors]

Here’s an interesting lens design, that would likely be quite compact. Perhaps a ‘pancake’ type zoom for the RF mount in the form of a Canon RF 20-50mm f/4-5.6 IS STM.
I think for such a lens to be desirable, it would definitely have to be extremely small, light and affordable.
More to come…

It might be quite small, but it would not be a pancake.

That sounds more like a (FF?) variation of an 18-55mm 3.5-5.6 Is STM. Something to pair with a super affordable RF camera.

It could be a semi pancake if it also is a collapsing design.

An RF 4.0 17 IS would be more interesting - at least for my purposes as (1) a good ultra wide and (2) a vlogging lens.

Stack of pancakes?

Not sure where to post this comment, so here we go:

Do you get tips on upcoming rebates? That would be very useful to know!

Thanks!!

What an interesting street lens.

If the R6 ends up beinge a 'low price' entry-level FF offering, this might be a kit lens option for it. If the optics weren't too bad, it would be interesting as a walk-around lens.

Yes but it really sounds like Canon is listening to SOME of your posts!

20-50 is an odd range. Feels like a crop sensor kit lens (28-70?).

I disagree. I think it's a great wide to normal range. I understand some have issues with short zoom ranges such as the Sigma 24-35 but it is a very good lens imho. This might be as well.

Why? Because 50mm is in the title?

 

[luka28]

in my opinion this would be a great walkaround lens, getting it wider then 24 is also a cool move since now all the mobile phones also get ultrawide cameras/lenses and like it or not camera manufacturers now need to fight that segment also. If it would be a pancake lens this would be instant buy or best kit lens ever invented.

You’re probably right. With the superior image quality were seeing these days, the ability to crop to size means this is a 20-70 or 20-105.

I predict we will see real digital zoom in the next few years where the sensor crops at the upper end. The key is controlling the zoom based on available image quality and how to set the zoom without fussy added control beyond the manual zoom ring.

I have a patent pending invention for this.

No, because he has stated many times about the R line needing small, light affordable lenses. Now maybe I got it wrong and he meant Primes, not Zooms. My humblest apologies if so kind sir.

I don't think so if the focal length is really 20-50mm. Maybe will be a cheaper STM lens but 20mm is another world from 18mm (28.8mm).

I believe there can be no wrong interpretation as he has opined about both small, light & affordables as well as 50mms. Then again, his opining on 50mm was in the realm of the EF, so perhaps it is I that is confused. In which case, sir, it is I who begs forgiveness...

Is f/5.6 all that small when Canon appears about to offer an f/7.1 lens?

Correction: Canon is bringing us an RF 24-105mm f/4-7.1 IS STM Macro - Canon Rumors

When you purchase through links on our site, we may earn an affiliate commission. Here's how it works. It looks like I incorrectly assumed the speed of the upcoming RF 24-105mm lens (I should know better). Canon is instead releasing an RF 24-105mm f/4-7.1 IS STM with 0.4x – 0.5x macro through...

20-50mm f4 would be more desirable.
to save on size try can always leave out IS.
F5.6 is less desirable

If this lens is real, I will start investing in Canon RF mount.
