Nikon to sue Sigma over OS tech

http://www.amateurphot​ographer.co.uk …t_update_news_3​07713.html

The link sums up most of the details thus far, it seems that Nikon dislikes Sigma's own brand of image stabilization and is moving to sue the company over their use of it.

I wonder if Canon is going to sue Nikon now...

Yeah, I heard from a Canon rep that a lot of Nikon technology is actually borrowed from Canon, but I believe they pay royalties for it.

Translation: "oh crap, the 120-300mm OS is really good, we better stop it!" lol jk

Naw I bet they are more worried about the 150mm OS
Because then Nikon will have fully lost their "Only stabilized lens on the market" slogan and will have to update their macro

Lol, Nikon will lose I bet, I mean, if Canon hasn't stopped Sigma yet, why can Nikon? Did they finally realize there is another manufacturer of good black lenses?

and with the all important, magic gold ring around them

Could be the events in japan perhaps? I dunno...

Seems weird since its been so long, but its also possible Nikon's just let it slide until now..

I am NOT sure who did IS/VR first, if i remember correctly, Nikon had VR in a compact camera before they made an interchangable lens with it..i think in 1994....Canon came out with the 75-300 IS in 1995...Nikon's first VR lens was the 80-400 zoom in 2000....

so its quite possible CANON is paying a liscensing fee to Nikon for the technology...or that theres differences in how VR and IS work...

Pretty sure Canon came out with IS first, at least, for the lenses. Nikon might have come out with it in a compact before, but I'm guessing that was sensor shift? Which should be completely different to in-lens stabilisation, but then I'm no engineer so I might be completely wrong.

LOL it was a film compact, it was indeed lens-shift stabilization! (It would be quite difficult to move the film plane to achieve the same effect..)

And it came out in 1994, I looked it up, Canon's first IS lens was the 75-300mm IS and it came out in 1995....

So Nikon had VR first but didnt put it into an SLR lens until 2000 when Canon already had several IS lenses on the market (The 100-400 and 300mm f/4 at least)

Guys... when they came out is irrelevant, when they patented is the key.

I think Sigma may have a case in this...from the article:
"Nikon claims: 'Although Nikon attempted to resolve Sigma's patent infringement through negotiation, a non-adversarial resolution could not be reached."

The fact that they couldn't come to a resolution may mean Sigma is confident they didn't infringe on any Nikon patents...

They are probably still pissed Sigma can even make NIkon mount lenses, much less stabilized ones.

This is true enough...

its also WHAT they patented...

its entirely likely Canon and Nikon both use different methods of sensing movement and that which is why Canon avoided being sued, Sigma might have reverse engineered bits of the Nikon 80-400 or something..

Keep in mind Sigma's first OS lens was the 80-400 OS, So yeah...Not saying they necessarily did but it maybe rings a bit suspicious...this was released in 2002 by the way...
