New Canon Patent Finds

More Patent Fun
A couple of New Patents filed by Canon this month.

Just remember, not all patents make it to market.

Sensor Based Stabilization?

The first patent found is for what appears to be sensor based stabilization. Could this be for a powershot, and SLR or perhaps a new EVIL camera system?

US Patent: 20100003025

LCD in Viewfinder

Viewfinder LCD

This one adds a small LCD in the viewfinder. You can keep the camera up to your eye and see through the viewfinder while reviewing previous images taken.

Lens Patents

Quick Post
I’m just travelling around a bit at the moment and I’m unable to format or research these patents thoroughly. I’m sure some of you will tear it apart. A better translation would be appreciated.

This Japanese site has posted some Canon patents he/she has found.

This is a direct email quote
Based on his investigation Canon made following patents.

EF300/F4 IS II with plastic lens.
http://egami.blog.so-net.ne.jp/2009-12-17

EF 300 f/4L IS II

This would be a welcomed lens by many.

EF70-210/F4 IS II with plastic lens
http://egami.blog.so-net.ne.jp/2009-12-12

EF 70-200 f/4L IS II

Not sure this lens needs an update yet.

EF300/F2.8 DO IS and EF 400/F4 DO IS with new double DO and IS
http://egami.blog.so-net.ne.jp/2009-12-02

EF 300 f/2.8DO IS

A lot of DO patents popping up. A lot of people ask for smaller and lighter lenses.

EF 15-24/F3.5-4.5 Fish eye zoom (not EF-S)
http://egami.blog.so-net.ne.jp/2009-11-27

EF 15-24 f/3.5-4.5 Fisheye

I think this would be a great fisheye solution. It wouldn’t cost a lot at first sight.

CR’s Take
All make some sense outside of a new 70-200 f/4L IS.

More Announcements in February?

From Northlight
I just received this info, appears it’s from Northlight. The 1Ds4 COULD appear in February as well as the new lowend dslr’s.

Whenever it’s launched, we can expect the 1Ds4 to come “with lenses”.

Interesting tidbit, the 1Ds Mark III received a “new” tag on the Canon UK site.

*UPDATE*
A bunch of lenses have also received the “new” tag. Site issues it looks like.

APS-C DSLR Announcements [CR1]
Received some added information about the February 9, 2010 announcements.

The EF-S 60 f/2.8 Macro will be replaced with an IS version. This goes along with a patent we showed you earlier. The timing is probably good for such a lens.

January 9, 2010?
I previously posted about a January 9, 2010 announcement. I think something was lost in translation and the source actually meant February 9, 2010. I have received confirmation about the 2nd date. I think it’d be a longshot to make announcements on a Saturday in the middle of CES.

It’d be fun if I was wrong.

CR’s Take
That’s all that seems to be out there right now. I’ve reported on facebook before that there would be a new lens coming that isn’t a replacement to anything currently in the lineup. I’m going to assume that will be the 14-24.

I’m going to go out on a limb here and please don’t take it as fact. There’s an obvious lens that would complete the trifecta of new zooms.

EF 24-70 f/2.8L IS II

Still searching for a patent. It would be nice to see all 3 launched at once. Canon’s recent history seems to show they max out at launching 2 L’s at a time. Correct me if I’m wrong.

2010 may be a good year for Canon zoom fans.
