Patent: Canon RF 10-24mm f/4 and Canon RF 14-28 f/2.0

shunsai · Oct 24, 2019

Looks like an f/2.0 trinity is in the making!

Wow, It's been a busy 24 hours in canon rumor land.

Wonder if the filter attachment will still be in the rear on the 10-24?

CanonFanBoy · Oct 24, 2019

My big question would be: Will the RF 14-28mm f/2 be rectilinear like Canon's famed EF UWA zoom?

I wonder if Canon introduces an EOS R firmware update with an option for rectilinear JPEG correction of fisheyes.

Could be a dynamite starry night lens if coma and vignetting are reasonable. Price will, however, be astronomical (no pun intended) for f2.

I'd assume so, I can't see a fisheye would be a high-priority and the zoom range doesn't correspond to the EF 8-15mm fisheye. My question is whether or not the 14-28 can take a screw on front filter.

Given the other RF zooms I think coma will be very well controlled, and way too much vignetting is a huge probability .

That was my other concern. That end of the focal lengths is very low on my list though.

Taking the RF 28-70 F2.0 as the yard stick, another RF F2.0 would most likely aim at the same thing:
1. absolute technical minimum of hard to remove aberations (esp. Coma here)
2. light touch on easy to remove aberations, i.e. distortion, CA
3. 95% sharp wide open at both extremes at F2.0
4. on par with the best primes when stopped down to 2.8
5. compromise on weight and size

I will not be able to resist if they make it happen

These guys are fucking legends. I might switch from Nikon. The focal length split at 28 is -so- sharp.

Anyone want to bet on the price? I’m gonna start the bidding on the 14-28 at $3,500

mclaren777 · Oct 24, 2019

The 14-28mm f/2 will be mine!

Trey T · Oct 24, 2019

Hopefully, the f/2 lenses will below $10K

I'm going to bet $2999 to match the 28-70. This lens and the 15-35 f/2.8 would certainly force me to make some hard decisions!

I guessing weight, price and IS will be the primary differentiators. I'm not sure if the 14-28 will be able to accept front filters. I'm leaning toward "no", but Nikon's 14-30 does accept front filters but is f/4. The 15-35 is for general use, so I see the 14-28 as a more specialized lens for events like the 28-70. This is even more true if the 10-24 comes out and is the RF equivalent of the EF 11-24. So one for general use, one for events and one for ultrawide landscape/architecture.

What the 14-28 may do is to kill off the 14mm prime. With the 15-35 at f/2.8, the 14-28 at f/2, what aperture should the 14mm prime have? Possibly at least f/1.4. Sigma designed one at f/1.8, which is too close to f/2 to justify 1600 for a prime for most potential users even if the zoom is at 3000. Before the advent of the 11-24, the 14mm prime anchored the ultrawide focal length range (rectilinear), but I'm wondering if the market will even support a prime 10mm or wider.

I am interested in Canon RF 14-28 F2.

If manual will reduce the size and price, no need to have auto focus for Canon RF 14-28 F2.

I'd be after the 14-28 f/2 for landscapes and astrophotography, but it's the front filter that gives me pause and consider the 15-35 instead. I really like having access to normal sized filters and removing the thread would result in considerable change for me. What I don't want to do is keep carrying both a 16-35 f/4 and a 14 f/2.8 at the same time when I can get one lens thats better for both astrophotography and landscapes.

The 15-35 on its own is almost enough to get me into the R system - I'm waiting on the high resolution R as it isn't a change I need to make right away. Either way, odds are good I'd buy one of those two lenses in the next couple years!

The Canon lens devision seems to be firing on all cylinders and producing some truly drool worthy lenses.

The frustration for me is I’m ready to jump full speed into the R system and buy a swath of new lenses however, there is just not a camera I’m remotely interested in buying.

The 1DXIII proves Canon has still got the magic touch (amazing camera if you need it) but wish they weren't so tragically slow with the Pro R camera.

It's been a year since the system launched... if the Pro R cameras (assuming one for speed and one for resolution) are out by the end of next year then you're talking about launching and fleshing out a new ecosystem in 2 years, which is pretty good.

That said, Canon RF lenses are great. I'm also waiting for the next R that will obsolete my 5D4, but in the mean time, I get to play with RF lenses. The R effectively replaced my 5D3 (backup camera) but I now use it more with the 5D4 than I did with the 5D3 as a backup. If the prices on the R/RP are discounted this holiday season, it might be worth straddling the two systems before the pro R is released.
