Q: 1. Does the accuracy of the focus at the long end (400mm) deteriorate over time? I'd be interested in hearing from someone who has owned the lens for at least a couple of years with heavy use.

A: After several years, there is no change in sharpness throughout the zoom range.

Q: 2. What country was this made?

A: According to the information we have, our current inventory's Country of Origin is Japan and USA. Please be aware this can change over the product's production life without notice.

Q: 3. What is the width of this lens with the included tripod collar on?

A: 13 -1/2 inches and I have a Kirkland collar on My lens . It's a very good lens really sharp

Q: 4. Anyone using this lens with the FTZ adapter on a Z body? I can't wait any longer for Nikon to make a native Z longer than 200mm and need to do something....

A: This lens would work just fine along with the Nikon FTZ adapter on a Nikon Z body.

Q: 5. I have a D3. Can I use this AF-S NIKKOR 80-400mm f/4.5-5.6G ED VR Lens with the Nikon AF-S tele converter TC-17E II and retain autofocus?

A: Only in bright light. In dim light it will do a lot of hunting

Q: 6. Will this lens auto focus with a D7000 and a TC-17E II 1.7x teleconverter?

A: While you can use the AF-S 80-400mm f/4.5-5.6G lens with the TC-17E II and the D7000, you will lose autofocus. Using this lens with a teleconverter, the lens will only retain autofocus with the newer Nikon DSLRs that can retain autofocus at f/8 (D4, D800/D800E, D600, D610, D7100).

Q: 7. how does the 80-400 compare to the Nikon 70-300 f/4-5.6 in image quality and automatic focus speed and accuracy?

A: The Nikon 70-300 f/4-5.6 is an entry level kit priced lens and will yield excellent results. Its compact, light weight and easy to carry. To quote Ken Rockwell's review: I've used this lens and it works just great. It's my first suggestion as the best inexpensive addition to a standard lens like the 18-55 lens. The 70-300mm f/4.5-5.6G has a more robust build with a metal lens mount. This lens features a SWM (Silent Wave Motor) enables quiet automatic IF (Internal Focusing) focusing, Vibration Reduction, engineered specifically for each VR NIKKOR lens, enables handheld shooting at up to 4 shutter speeds slower than would otherwise be possible and Two ED (Extra-low Dispersion) glass elements minimize chromatic aberration across the entire zoom range while ensuring high resolution and contrast that ensure superior optical performance.The 80-400 for starters has a longer focal length range. In addition to regular autofocus and manual focus, two other focusing modes are available: A/M (Auto-Priority Manual Mode) enables an easy transition from autofocus to manual during AF operation, with a low possibility of unintentional switching, while M/A (autofocus with manual override, MF priority) allows switching from AF to MF with virtually no lag time by turning the focusing ring--letting you seamlessly switch to fine manual focusing while looking through the camera's viewfinder. A SWM (Silent Wave Motor) utilizes ultrasonic vibrations to provide quick, quiet, smooth and precise auto focusing performance that is ideal for use with video and subject-tracking applications. Internal Focusing is used to maintain an overall compact lens form-factor and to produce overall faster performance. The lens will not change in size during AF operation, enabling a closer focusing distance without the danger of damaging the lens' front element.Built-in image stabilization counteracts the effects of camera shake, allowing you to shoot at shutter speeds up to four times slower than would otherwise be possible. A dedicated VR setting for tripods gives you the sharpest imagery possible without working against the image stabilization system.ED Glass Elements (1) super ED (extra-low dispersion) and (4) ED glass elements help reduce chromatic aberrations throughout the zoom range and produce higher image sharpness, clarity, and color fidelity. SIC (multilayer Super Integrated Coating) is applied to the individual optical elements, as is a Nano Crystal Coat to minimize surface reflections across a wide range of wavelengths and prevent lens flare and ghosting--resulting in greater overall contrast and light transmission.

Q: 8. Hi , Is it possible to connect the camera to an android OS ? Does it need a special driver or is it like a regular UVC camera ?

A: Unfortunately this model is not able to be connected to an Android OS, my apologies. You are correct it is a regular UVC camera.
