Canon Looking at New RF-S Prime Lenses for APS-C, Including an RF-S 10mm F2.8

[Canon Rumors]

There is a new round of optical designs from Canon showing off what appears to be APS-C prime lenses. We all know that Canon does need to add a few more native RF-S options to their lens lineup. There are four new designs that are likely for APS-C cameras, and they look quite small size, […]

I don't know. Will anyone be interested if Sigma makes the RF 17-40mm f/1.8 DC Art?

Warning: digital correction of distortion required.

Interesting that the patent design for the RF-S 28/2.8 looks very different from the existing RF 28/2.8. I suspect if any of these designs become products, it will be the wide one(s).

And the 10-18 f/2.8.

I would be interested in an RF-S 10mm F/2.8 or RF-S 12mm F/2.8 if it's small enough. I love 12mm on Canon APS-C and the 10mm would be great for video work! So long they don't go too far past their "total lens length" of 65mm, it think it can be compelling. But their 28mm F/2.8 for full-frame is even shorter, I wonder if they can make it even shorter.

On another note, the 12mm and 18mm would be very compelling street-style prime lenses for Canon's smaller APS-C cameras.

I would like to see them make an RF-S 22mm or 24mm pancake. I had the EF-S 24mm but sold it as I moved away from adapted lenses. But now I wish I would have kept it.

Ever since the EF(-S) days, I have been waiting probably close to 10 years for the rumoured 10mm f/2.8 that was patented. And as we all know, every patent gets turned into a released product /s

I suspect if any of these designs become products, it will be the wide one(s).

I would tend to disagree. But only because of Canon's reluctance (regarding APS-C) to release anything that isn't going to either be incredibly popular or cost-effective.

The R50 has sold quite well from what I understand - but then again, the reasoning to produce the R100 is anyone's guess.

And all the first-party RF-S lenses (excluding the fisheyes) have been within the cost-effective range.

Canon has lost any incentive to take calculated risks or focus on anything other than their professional range of cameras/lenses. I'm just glad the Sigma and Tamron partnerships have proven fruitful.

I was under the impression that Canon had no interest in APSC wideangle primes, and thus ceded this territory to Sigma.

Given that there already is the 28mm pancake lens for RF there is little hope for a pancake in a similar range as RF-S I guess.
28mm is too long for my personal taste so I would have prefered a 24mm pancake as well.

They already do. The lens is currently sold in RF mount on B&H for $919. How well it has sold is a different matter. I personally plan to buy one after the R7II.

I own the lens and recommend it. I waited for him for half a year. According to my dealer, the manufacturer is having problems with supplies in sufficient quantities.

 

[Maximilian]

Even though I am very pleased with third party offerings like Sigma and Tamron, I'd really like to see Canon doing more on the RF-S side as well.

It is a sad situation that Canon didn't even convert existing and highly regarded EF-M lens designs until today.

And the old "double zoom kits" are really annoying, even if they are still well sold at entry level.
I still don't get, why Canon did decide to design the RF-S 55-210mm F5-7.1 IS STM, instead of converting the EF-S 55-250mm f/4-5.6 IS STM.
I don't see the size/weight advantage over losing the extra 40 mm and the brighter aperture.

The RF-S 55-120210 (thanks, @Maximilian) has fewer elements than the EF-S 55-250, and far fewer than the EF-M 55-200. Thus, the 'advantage' of the RF-S 55-210mm is not to the benefit of consumers but rather to Canon – it's cheaper to produce and Canon still charges more for it meaning an even higher profit margin.

 

[Exploreshootshare]

The RF-S 10mm F2.8 would be a great equivalent to the FF RF 16mm F2.8 which afaik sells pretty well.
At this point, I´d just be glad if Canon releases RF-S primes.

 

[Maximilian]

The RF-S 55-210 (corrected that for you ) has fewer elements than the EF-S 55-250, and far fewer than the EF-M 55-200. Thus, the 'advantage' of the RF-S 55-210mm is not to the benefit of consumers but rather to Canon – it's cheaper to produce and Canon still charges more for it meaning an even higher profit margin.

I can understand these arguments, but from the customer POVW (thanks, neuro) this is just
If - at least - it would have been much smaller, but it isn't.

 

[neuroanatomist]

I can understand these arguments, but from the customer POVW (my turn ) this is just

Agree, but at least there's a reasonable reason. I have never used the EF-S 55-250, but I quite like the EF-M 55-200 (posted this shot taken with that lens earlier today).

 

[Maximilian]

... POVW (my turn ) ...

Thanks for that catch...

... I have never used the EF-S 55-250, ...

I've used it quite a lot for traveling (light) and for being cheap (in case of theft) together with my 200D and it performed (both photos @250mm plus cropping):

I have this one for 6 six months. Since I bought it, it is my go anywhere lens except when I need long ones for wildlife. I am extremely pleased with it. Now contemplating to buy 12mm prime or 11-20 from Tamron.

 

[blackcoffee17]

They never release anything anyway. If i every buy a Canon APS-C camera, i will be perfectly happy with Sigma offerings.

RF-S 28mm F2.8？ Oh there already have a RF 28mm F2.8....small, cheap and strong...​
