Canon RF 14-28mm f/2.8L IS USM Z Up Next?

F2 L trinity --> hopefully there will be lenses to complete it
RF 28-70mm F2
rumored:
RF 24-70mm F2
RF 70-135/ 150mm F2
RF UWA F2 zoom --> I am guessing it will either end at 28mm or 24mm depending on what Canon does with the successor of the RF 28-70mm F2. I have no idea where it would start.
I'm still interested in new F2 zooms! I would likely purchase a 24-70 F2 if it's not much heavier than 1.0 kg.

Re: UWA, while I'm dreaming, here are some other F2 designs I would be interested in . . .
14-24 F2
16-28 F2
24-50 F2

Sounds like a great trip! Have fun and enjoy it! :)

Mine is the RF14-35/4, RF24-105/4 and the RF100-500 under 3kg

Worst case, I would drop the RF24-105/4 for my 2 lens kit under 2kg. Covers landscape and telephoto with cropping on the R5 if needed. Not good for portraits though :)


Just the lenses is under 3kg.
14-35 F4 + padded case 649g
24-105 F4 + padded case 810g
70-200 F4 + padded case 872g
35mm F1.4 + padded case 666g
Sub total 2997g

But I have a carry on limit of 7kg to meet with 2 camera bodies, MacBook Air, cards, card readers, external SSD drives etc etc + the weight of the bag itself. The best I've found is the F-Stop Dalston 21L bag which weighs only 820g

Instead of a 14-28mm f/2.8, which seems like a little too sacrificial over the practicality of a 15-35's range, I would prefer Canon to see what lens they could come up with if they created a large ultra-wide lens body like the existing 24-105/70-200. They could create a totally new and unique zoom range that many shooters could find useful..say a 14-55mm f/2.8...this would also play well with any upcoming EF-S cameras and the R50V for more serious productions. Perhaps that would be too large of a lens as I speak out of my butt about lens design fantasies. haha

If canon decides to keep all the Z lenses the same size it wouldn't be unreasonable to expect a bigger zoom range than the existing 15-35 f2.8. It's probably more realistic than my fantasy of a 20-200 f4 Z

I share all of your dreams, particularly the one about an RF 24-70 f/2 and the 24-50! :)

For city travels, I often go with a two lens set-up:
RF 14-35mm F4 L
RF 70-200mm F4 L

When I take a third lens, I have to choose between the RF 35mm F1.8 (more for cityscapes at night) or RF 85mm F2 (more portrait-like pice). I usually to have at least one lens that has a brighter aperture than F4.

For hiking,
I stick to the 35mm F1.8 and a telezoom. I usually don't carry the 100-500mm on hikes longer than 10 km. I opt for the 70-200mm F4 or the 100-400mm which I sold to my father-in-law, but fortunately I can burrow it at any time.

Btw: the Dalston backpack looks quite nice and interesting, but since I already own a great backpack, it won't be a purchase for me.

I´d preorder in a heartbeat! Actually two, my heart will definitely skip a beat once it gets announced :)

Currently, I can´t imagine buying a UWA f2 zoom because the RF 14-35mm does a real great job and f4-f8 works perfectly for landscapes. I´d be more interested in a 70-135mm (or longer) F2 zoom, if it is max. 1kg

I believe that it would cannibalise sales for the RF15-35/2.8. There isn't that much difference unless they can significantly improve vignetting, weight etc even with equivalent sharpness.
It will certainly cost more money, be internal zooming, be less compact, and support the power zoom attachment.
If anything canabalizes the RF 15-35 f/2.8, it is the RF 16-28 f/2.8.
I say the more choices the better.

It would be a Z lens. Clearly that concern didn’t bother Canon in terms of the RF 70-200/2.8 lenses.
Yep, I get that it would be a Z lens but what would be substantially different from the RF15-35/2.8? VCM motor = tick but otherwise?
The RF70-200/2.8 Z vs non-Z has the collapsible feature so smaller and lighter. For the 14-28/2.8 the difference would be ?

I have the same 7kg carry on limit but get around it by using a eScott Vest to actually carry the stuff and a Lowepro 450AW which can carry all the gear once past checkin. I regularly carry >12kgs in carry on this way.
16" MBpro and RF00-500 goes in the backpack adding up to roughly 7kgs.
2 bodies, wide angles lenses, big powerback/batteries, protein bars etc for the flight goes in the vest.
Not that this is not my hiking setup or even a walkaround setup but getting to a destination safely with gear. If diving then strobes, housing, fins etc goes in the checked in bag. 30kg bag is preferable in this case.

I'm not getting your point here. Are you suggesting that the potential RF12-28/2.8Z will be the same form factor as the 2 zoom Z lenses that you showed? Does the patent give this lens length for instance?
Fair point, and my assumption of it being the same size could be wrong. The patents for internally zooming 14-24/2.8 and 15-35/2.8 lenses are shorter than the current Z lenses, but those patents may not become the actual lens.

Presumably they’d want the PZ-E2 to sit in the same place relative to the camera body as on the other Z lenses (having it be closer to the body would necessitate adjusting a rig to switch between Z lenses). If they want the attachment in the same relative position, the patent for the 14-24/2.8 won’t be made because it’s shorter than the position of the outer screw hole.

I will definitely be buying the wide angle Z lens, but I'm really surprised it is going to be a 14-28mm. It really needs to be approximately the same size as the other Z lenses for it to make sense and a 14-28mm seems like an odd range for that size of lens. Odd. And for video, it is more useful if the lens 40mm rather than 14mm.

FWIW, the most recent patent has a 14-24/2.8 that's significantly shorter than the current Z lens length (too short, as I mentioned), but the 15-35/2.8 in that patent is only a little bit shorter could be made at the same length with that basic optical formula.
