Patent - Canon Tilt-Shift Adapter for EF Lenses

[siegsAR]

Canon’s method of getting around the tilt-shift conundrum using standard lenses with standard image circles on a full frame or APS-C camera makes me smile. It’s not quite groundbreaking. Just really smart engineering using tech in a different manner than which is was originally purposed.

You might think Canon would have used an image enlarger inside the adapter to increase the image circle size but Canon went a different route entirely.

I think this is referring to US patent 20150234198

http://appft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.html&r=1&p=1&f=G&l=50&d=PG01&S1=((Canon+AND+lens)+AND+adapter)&OS=Canon+and+lens+and+adapter&RS=((Canon+AND+lens)+AND+adapter)

Since its likely to cost as much as just buying a real tilt-shift lens, I doubt we'd actually see such a kludge.

The patent as shown is only for cameras with a short enough flange distance (it says so at the start of the patent)

What interests me more is that the entire system as described could form the tilt/shift mechanism for a new range of TS-E lenses.

Even having just the shift amount in EXIF could allow for some much more precise correction of residual lens distortions.

Who knows? ... autofocus with tilt ... just touch two points on the view screen and off it goes ;-)
(OK, three points if you want to work out the plane of tilt)

I'd LOVE to see this in real life. I would even buy an EOS M for this thing...

 

[dryanparker]

I may be behind on this topic, but any chance a new EOS M would step in to compete with the Sony A7R line? More of a professional system, full-frame, high resolution, but smaller profile...?

Probably not. Mount is too small for FF, and all the offerings to date are targeted for minimal size (and slower apertures). It's also not priced that way either.

not it isn't the mount is the same inner diameter as the E mount. canon would have to change the internal baffling and the size of the EF-M electronic connector plate such as Sony had to do to support the larger sensor, but it would fit, since the sensor corners, like with sony can tuck under the mount slightly.

Right...

My question is whether they might re-design the entire system to compete.

as far as this?

probably not. to be honest - why do they have to? their existing full frame cameras compete more than well enough.

all statements from canon in regards to the M is "keeping it small" including the lenses, and they can't do that with full frame.

a TS adapter is kind of cool - it would be nice if they also did a focal reducer adapter as well - now that would be a nice addition!

Nope. If Canon comes out with something else, it won't be an EOS-M. And compete with what? Sony bodies might be a bit smaller than their Canon DSLR counterparts, but the lenses are just as big. Its 35 f/1.4 is heavier and is about the same size as the 35L.

The EOS M and the Sony A7R are both mirrorless systems, correct? That's what I'm talking about re: compete. You're right about lens size, etc. And I realize the A7R line is probably more of a competitor for the 5D/D800 lines than another mirrorless offering. I'm just floating the question since a previous rumor mentioned the EOS M4 would be a departure from the previous three.

I took that comment from CR as basically stating a gobal release of all items versus in the past.

Or they could make a camera with a tilting sensor?

The tech has been around in Olympus omd's for a few generations, and is in the a7ii. All thats needed is sone user controls...

I was toying with buying one of the far eastern ef-m to m42 ts adaptors, but have decided to go with the arsat lenses instead, as I am using ts lenses, shamefully, for fake minature, so ultimately effect is more important than out and out iq.

Interesting that the technology exsist with the ef mount to impart sensor crop (although the clues were there with the e-ttl-ii guns) and makes you wonder a little bit why they bothered with ef-s at all....

 

[RGF]

A friend has Hasselblad and they have an adapter make all their lenses into T/S.

Of course camera with tilting sensor would be smaller and much more convenient (with appropriate controls, as you say).
Neither Sony nor Olympus make cameras with tilting sensors, they move in a plane but do not tilt.

Lol people used to say E-mount is too small for FF, yet FF cameras appeared. EF-M mount is even larger than Sony's one.
Also you are probably failing to grasp that the adaptor in the patent is for using *EXISTING* EF lenses on a EF-M body

Pitch & Yaw are tilts -- camera shake which IBIS designed to correct against, but not directions around which sensor moves.

Sensor movement

current sensor movements are far too small for any useful tilt/shift functionality.

If you consider how few people understand (or want to know) how to make effective use of T/S lenses, then adding a whole new set of movements to a body is such a niche product that has no interest to a manufacturer like Canon.

Lens tilt/shift - yes ... Adapter - maybe ... sensor tilt/shift - not a hope

 

[Tinky]

I don't know how few understand, in my time with the 24ts-e and shooting on film it felt a lot like trial and error at times, there are great online explainations of the principle behind it, but no real hands on guides for things like opposite tilts, or how little acutally makes such a difference, and how easy it is to over tilt etc...

The shift bit is easy, the tilt bit needs a dummies guide...

It's more obvious on the 80mm I currently use (effectively 135) and live view helps immensely... I don't know if it is a matte focus screen issue or what.. maybe a microprism with grids would be easier..

EF seems a daft choice as the image circle hasn't a great deal of latitiude.. the canon TS-lenses are almost medium format in size, adapting EF to EF-m or Ef-s may work well... EF to EF? Without correction element for infinity focus etc...

Will be interesting to see where this one goes.

And I am a heretic. I want TS to use for interview effects (portraiture I guess) and fake minature. Burn him, burn the witch.
