APS-C 11mm f/2 Patent

[PHYSICA]

I think….. It is a April Fool………….But if it's true , I'm sure I will sell my 10-22

BTW, for EF-S Lenses….. I wish to have a 15mm TS-E lense for APS-C…. (daydreaming…hoho)…..the only TS-E lense which is wide enough is T-SE 17…… 24 is not so that wide for APS-C….

This patent is for a projection lens for an LCD-based video projector.

The corresponding US patent application is 2011/0038054.

Thanks to my colleague Hans Jørgensgaard for making the connection on this (he is my "go-to guy" on Canon patents)..

Best regards,

Doug

Thanks, Doug!

I guess at least one other person in this thread was on the right track:

What is the item labeled "P" in the drawing?

I suppose "P" = projector.

It was a April fools Day joke, or at least published by Egami on April 1.

Cool, Now now they just need to a 30/35mm 1.8/2 and I'd be happy.

This does make sense.  The "LCD" thing didn't seem right, and I was trying to figure out what "s" was on the left.  A marking for a screen makes much more sense than a subject.

Case closed. Moving along.

Okay, good point. But I wasn't talking about using a 4//3rds adapter, but a competitor to those cameras by Canon. i.e. could a lens built on spec to this patent be destined for a new Canon APS-C compact mount rather than EF-S, for example something like the Fuji X100 but with interchangeable lenses.

Could this be used on a m4/3 competitor for example, incorporating a fixed length lens but using a kind of digital zoom say 4/5 x?

Its a patent, not a product.  Canon files thousands of them a year.  Only a very few actually become products. 

However, even if there were a adapter, it would not make much sense to mount it to a micro 4/3 camera, there would be no electrical connection, so the aperture would not work.  Without control of the aperture, a lens is not going to work out well.  It would be, of course, manual focus.
