New Autofocus RF mount tilt-shift lenses expected after next round of camera announcements
- Thread starter Canon Rumors Guy
- Start date
A great way to shoot butterflies was with a 90mm TS-E and a 2x teleconvertor or a closeup lens. You can get the entire wing in focus even at fully-open, and perfect once you stop down to f/16 or what have you.

I don’t think youre their target audience. Architectural photographers would love some new TS lenses.

They need more focal lengths, not af. Especially needed is a 35mm TS. Most people use a tripod and work slow when using a tilt shift and don't need autofocus.

Autofocus on digital cameras is different with live view. Rather than needing to zoom and twiddle the focus ring, in this case I would put the focus box over what I want to focus on and press a button. Maybe that doesn't save a lot of time but it is a step forward.
Autofocus on a TS lens also allows the lens to be used hand held as a regular prime lens, without needing to change lens or camera.

Hi -
You're absolutely right, and I apologise.
If the sole use you have for a lens that can tilt and shift is to shoot long exposure shots at blue hour with the lens only shifted, then auto-focus is going to be of pretty much zero value to you. But I can't help but wonder - do you make a habit of posting comments on every single piece of photography equipment that gets discussed, when it has no relevance to your "shooting style"?
An example of a blue hour long exposure photo shot with lens movements where auto-focus on a TS-E lens would not have been particularly useful.
But if there is anyone out there who doesn't solely use these lenses for their shift capabilities, and solely when shooting at blue hour, and solely for long exposure shots, then I stand the my second and third paragraphs in my response.
Speaking as someone who has - over a period of decades - extensively used lens and camera movements for more than just long exposure blue hour shots (although I will admit that in my time, I've taken more than my fair share of those), I can absolutely assure you that those final two paragraphs of my post are completely valid.
An example of a photo taken with lens movements where having the ability to automatically set the plane of focus as described in the Canon patents would have been of significant benefit (time is money), but the lack of such functionality didn't prevent the shot from being able to be taken.
Now if you excuse me, I have to dash - I've heard there is a discussion somewhere about another piece of equipment that has no relevance to me, and I need to make sure everyone knows it.

Thanks for this.
I’ve been following the discussion because I’d really like to know what people use TS lenses for. Mostly it seems to be architecture (which makes sense, but I don’t shoot buildings) and the “toy” effect (which would be fun to play with, but I think the novelty would wear off quickly). So I concluded this lens wasn’t for me.
Then you posted this and it’s very relevant because I just took a macro of a butterfly the other day and the head and leading edge of one wing were tack-sharp and the rest of him/her was soft. Suddenly a TS lens makes perfect sense….
I make a habit of commenting on things that interest me. Given that I own and use two TS lenses, new versions are of interest. Autofocus in such lenses doesn’t really interest me (or others here, evidently), but other potential developments (wider AoV, encoded movements) are of interest. Thus my comments to that effect.
Do you understand the difference between a piece of photography equipment and the specific features of that equipment? In an analogous example, I have no use for the aperture ring on the 24-105/2.8…but it’s an excellent lens and I use mine frequently.
But I can't help but wonder - do you make a habit of posting comments that make you look like a jerk? Don’t trip and fall on your face as you dash off.

So it seems - I've just taken a look at your profile and I note that you're well on your way to making 2^15 posts here. Congratulations.
I've just had a look at my profile, and can report that, given this is just my 5th post here in close to a decade, no - seemingly I do not.

I still wonder whether the RF10-20/4 and keystone etc correction in post would lessen the need for wider TS-E lenses. Lighter, cheaper as well.
Would the need for accurate leveling be an issue for handheld use? Would leveling be always on the horizon or perhaps dependent on the architecture/PoV?
I am guessing that Canon will need to show why AF is advantageous for wider TS-E for people to upgrade or perhaps it is just filling a RF niche when the EF versions are discontinued (eg RF600/4 and RF800/5.6).
If the longer lens have good macro capability then perhaps they could replace the EF180/3.5 macro

I watched the ABC Australia show "Stuff the British Stole" on the Parthenon Sculptures (Ep1, series 2). Series shows the complicated arguments for/against objects in the UK that came from other countries
One part of it was the use of handheld 3D scanners of the marbles in the British Museum for the purpose of recreating the marbles ie accurate copy in marble for the Brits to keep (or even restore with colours etc) and the original ones go back to their spiritual home in Greece. 3D scanning was not against the British Museum's rules... of course, the Brits declined the offer but the marbles were made anyway.
Free with login setup but not sure if access outside of Australia is possible.

if all these patents make it into the camera(s) and TS lenses - it will be absolutely bonkers and ground breaking.

Definitely. Not sure how likely that is (I’m skeptical) but I hope we’ll see something other than just RF equivalents of the current TS lenses.

LOL. If all those patents make it into these lenses, they will be absolutely bonkers costly and ground breakingly expensive. And you complained the RF 50/1.8 is too expensive.

Square Sensors + AI = Better Images
... quite a revealing post here
(particularly the third paragraph [bold and italics added by yours truly]), although perhaps not in the way it was intended. (Hit click to expand to see the third paragraph.)I visit CR daily because it is generally fun and I often learn something about photography and technology.
But I occasionally take a break from CR when the tenor of the forum posts gets toxic--toxicity reduces the fun.
