Cool Tamron Patent
« on: February 21, 2011, 10:50:06 AM »

I know, I said “cool” and Tamron in the same sentence. It’s true though.


Want to IS/VC your lenses? Just add this converter!





  • Applications from Tamron

  • Patent Publication No. 2001-33692, 2001-33693, 2001-116994

  • Actuator and a shake correction

  • Power the camera from the supply, or battery use

I can't find a link but I'm positive Nikon has has similar patents regarding IS in an adapter / teleconverter for maybe 10-20 years?!

Wonder how Tamron have managed to get similar?!

Re: Cool Tamron Patent - from 2001?

A patent no of "2001-33692" lets me think that this is a patent from 2001.
So I don't expect that there will be a product...

If it worked without degrading the optics or light, they would sell like hotcakes. Be nice if it were more than a dream and makes it to the market.

Holding my breath...

Patents must be specific, not just a idea.  Thats why you see oll the actual values for lens groups in a lens patent.  If you can achieve the same goal as a existing patent using a different formula, there is no conflict.  Being similar is allowed as long as you do not copy specific key features.

I think you are correct. I don't know Japanese, but the Google Translation has some phrases in there that seem to be a tip-off that the blogger was talking about past patents:

Quote
I suddenly thought I checked, the patent application seems to be sure. Image stabilization is likely to be no edge from Tamron, more than 10 years ago. It seems after all was not released. Various reasons are considered, then the Tamron may have had no image stabilization technology.

Sure sounds to me that this is not about a new patent application. Too bad. It could make the Canon 400mm non-IS pretty appealing.

As it is a teleconverter I take it this would increase focal length as well as add IS/VC?
