My granddaughter is a TA working on her Masters at Virginia Mason. She got her BA at Western Washington in Bellingham we went up there for her graduation. She and we both liked Bellingham better than the beltwayIf I ever visit Boise, I'd 100% take you up on a birding excursion, Ken, thank you!
Washington DC: that's right around where I lived before I moved here 3 years ago. If you ever go back, I have some top birding places for you to check out (on the Maryland side)
But I am a sage steppe nut so all those trees are down right freaky LOL
Small world ... my granddaughter has some friends that have family with horses not far from her place there and that makes her happy. She is going to be working at a dude ranch in northern Idaho this summer.Nice, I am a George Mason alumni

A patent application that Nikon is interested in was released on April 2, 2024. Several examples of ultra-telephoto zoom optics that are very similar to "NIKKOR Z 180-600mm f/5.6-6.3 VR" under Tamron's joint name are posted.

[Issusance] It realizes a zoom lens and imaging device that has small size, light weight, high optical performance, and can reduce the size and weight of the anti-vibration group.
In recent years, imaging devices using solid image sensors such as digital still cameras and digital video cameras have become popular. Along with that, the optical system of these imaging devices has become more high-performance and smaller, and small imaging systems are rapidly spreading. In particular, for telephoto zoom lenses with a long focal length, there is a growing demand for miniaturization and weight reduction along with the high performance of the optical system.
In particular, telephoto zoom lenses are prone to image blur when vibration is accidentally transmitted to the shooting system in the imaging device. Traditionally, various zoom lenses have been proposed with a mechanism (anti-vibration mechanism) to compensate for image blur due to this accidental vibration. For example, an optical system that moves a part of the lens group that constitutes the optical system in a direction slightly perpendicular to the optical axis and compensates for image blur caused by vibration is known. In general, in order to prevent image blur by vibrating a part of the lens group, the lens group (anti-vibration lens group) that vibrates for image correction is required to be small and lightweight.
However, with the zoom lens described in Patent Document 1, the miniaturization of the anti-vibration group is not enough, and with the enlargement of the anti-vibration drive mechanism, the entire zoom lens may become larger and heavier.
One aspect of this invention aims to realize a zoom lens and imaging device that is small, lightweight, has high optical performance, and can reduce the size and weight of the anti-vibration group.
I may be misinterpreting the patent, but it seems that it was a joint development, at least for the VR system. I think Nikon makes the lens.
I'd be shocked if Nikon makes it. Probably half of Tamron's business is white-label lenses for Nikon, Sony (which is its largest non-institutional shareholder), and others.
I was told by a Nikon employee that Nikon makes the lens. But I cannot verify that. It’s also possible that Nikon & Tamron have joint production facilities in China.
