It seems that these days, 3rd party lens manufacturers are doing everything they can to try to upstage everybody else. After Nikon’s recent introduction of the 105mm f/1.4E, Tamron have now filed a patent for a 115mm f/1.4 VC lens. If they make it, this would make it the longest f/1.4 autofocus* lens out there, taking Nikon’s recent crown.
What’s even more interesting than the slightly longer focal length is the fact that this lens comes with VC (their version of VR/IS). The Nikon 105mm f/1.4 doesn’t have any kind of built in stabilisation at all. If this becomes more than just a patent, that single feature alone could see it winning out for Nikon shooters. Assuming the optical quality stands up to demands.
