Northlight Images has found a US patent showcasing a new way to design tilt-shift lenses.
Says Northlight Images:
When you tilt a lens there is often some unwanted shift introduced, by dint of the lens design and where the physical axis of tilt runs with respect to it.
It’s why I modified my original TS-E90mm) – the new version, as with the 17/24mm, has the ability to change the shift/tilt axis relationship. However, Canon has looked at correcting.
In the patent, the unwanted shift from tilt is referred to as composition shift (a useful term – I may be using it in future ;-) )
The tilt function of the new lens designs is given by offsetting a lens element in front of the stop – the shift is offset by an opposite movement on the rear (camera) side of the stop.
We have had RF mount tilt-shift lenses on our roadmap for quite some time, and the rumors say these new TS-R lenses will have autofocus. This patent doesn't touch on that, but could give us an idea of what Canon is thinking with the new RF mount tilt-shift lenses.
- If they make it
- If it's a 14/15mm lens
- If I can afford it
- And if it's a Canon
"The patent includes example designs for quite a few longer lenses (number rounded to nearest ‘standard’)
35mm f/2.8 | 85mm f/2.8 | | 135mm f/4 | 230mm f/4"
Quote from the original Northlight article linked in the opening post.
Imo this is the next patent for a tilt lens without shift.
24-100 with tilt anyone
How they are fitted together in an actual product often won't appear until after the lens is launched.
Tilt without any [normal] shift would be a mighty specialised lens.
If you want to put all the current bits I've seen in patents together, we could get an RF 24-100 f/4 zoom AF tilt/shift lens with powered movements - operated with lens rings (as opposed to the current knobs) and providing full EXIF data. A 20-50 would perhaps appeal more to me
As to price.? yes, well... if you need to ask...
New Xenon FF-Prime Cine-Tilt Lenses from Schneider-Kreuznach
I expect a fast tilt only prime for event and sport photography a135mm 2.8 e.g.
A zoom would probably to large, to heavy, to expensive and to fragile to get in the market.
Another question: which body could handle a electronic tilt lens?
