A new tilt-shift related patent from Canon
A patent to help usability by changing the grind lines on the EVF or LCD when tilting, shifting and rotating. This is definitely something I could see being useful in a tilt-shift macro.
Patent Publication No. 2013-81129 (Google Translation)
- Publication date 2013.5.2
- Filing date 2011.10.5
Shooting assist functions suitable for tilt lens
- Rotate display grid lines
- The angle information of the tilt lens to determine the angle of the grid lines
- To align in the direction of change of focus, the angle of the grating lines, easy to compose the picture

New Tilt-Shift lenses in 2013?
The 45mm and 90mm tilt-shifts have been on the replacement cycle for a while now, probably since the day after the 17mm and latest 24mm tilt-shifts were announced a few years ago.
Apparently we’re going to see a new 45mm and 90mm tilt-shift announced in 2013. Both of the lenses will receive the “L” treatment and the updated movement mechanisms. I would like to see the lock knobs built a bit better, I found them to be unreliable in the rental world and they are quite an expensive repair.
Also coming in 2013? A new “specialist lens”. I’m not completely sure what would be considered a specialist lens, although a new macro would probably fit the bill.

New Macros and Tilt Shifts Coming?
Recent patents have shown new Macro and Tilt-Shift lenses. Below I’ve listed them.
Explain a patent
You cannot patent a lens per se, but you can patent an optical formula. I think it’s safe to talk about patents, as many of them have turned into actual consumer products.

What’s not coming
All the patents for DO lenses has sparked some questions. I’m told that no DO lenses are planned for the near future.
What is coming?
From a decent source, this is claimed to be the roadmap. Timing of this stuff is still up in the air. You just have to look at the delays of the new lenses until March to see nothing is ever written in stone.
There will be an abundance of “speciality” lenses. I can see it happening, you’re not going to sell that many tilt shift lenses, so production is less of an issue.
Tilt Shifts
Both the TS-E 45 and TS-E 90 will be updated in 2011. Availability may not be until 2012. Both lenses will be L.
Macro
A new long Macro is coming. It may not be 180mm, but it will be an L. An EF-S macro with the hybrid IS will also appear.
More L’s?
There’s nothing to add about the usual suspects for replacement. We all know what’s been talked about countless times.
A wide angle f/4L with IS is “definitely coming”.
Bodies?
Nothing on bodies at the moment.
Lots of murmurs about an entry level full frame camera. Nothing concrete and this idea pops up every so often.
Lens Rentals Used Gear Sale
LR still has a few used lenses for Canon. I’m surprised to see 70-200 f/2.8L IS version 1′s in stock. A 10-22 at $599 is still available. It’s a fantastic lens!
