I have a Nikon D7100 camera, wanting to know if the Nikon AF-S 80-400MM lens will it work in all modes? Or would it be better to use the AF lens?
Thanks,
Sam

AF-S means that the lens has a silent motor in it. It will work.

Either one will work on the D7100.

Both will yield the same result, S model has silent motor, correct?

Both will function fully. The new one is better, but more expensive.

The "Nikon AF-S 80-400mm f/4.5-5.6G VR" has a built-in motor, the older one, the "Nikon AF VR 80-400mm f/4.5-5.6D", does not have a built-in motor, so it will only autofocus with cameras with a focusing motor. The D7100 has the AF motor. The AF-S will focus faster.

As I said: AF-S means that the lens has a silent motor in it. It will work.

Googled from the internet:

Question
What do the terms ED-IF, DX, AF-S, etc. in your lens names mean?
Answer
Nikon has a long history of making excellent lenses and we have many different technologies used in our lenses. Here is a brief glossary of our lens terminology:

ED - The lens uses Extra-low Dispersion glass for superior image quality, especially at wide apertures.
IF - Internal Focus, focus is accomplished without the lens barrel rotating or changing length, an advantage when using a position-sensitive filter such as a polarizer.
AF-S - Focusing is driven by a "Silent Wave" motor in the lens instead of the focus drive motor in the camera. AF-S lenses focus faster than standard AF-Nikkors and are almost completely silent. AF-S lenses with a "II" designation weigh less and are generally smaller than their equivalent predecessors.
D - The lens provides Distance information to the camera electronically for more accurate light metering.
G - The lens has no aperture control ring and is designed to be used with cameras that allow setting the aperture from the camera body. G lenses also provide Distance information to the camera.
DC - Defocus Control, the optical characteristics of the lens can be altered to change the appearance of the out-of-focus elements in the background or foreground.
VR - Vibration Reduction, lenses with this feature can be hand-held at lower shutter speeds than non-VR lenses because they have a system that detects and counteracts vibration associated with hand-holding a camera and lens. (VR operation is available only with specific Nikon cameras.)
DX - The lens is specifically designed for use on Nikon digital SLR cameras. It produces a smaller image circle for more efficient coverage of the imaging sensor in these cameras, which is smaller than the 35mm film frame.

When Nikon says, "silent," is that replacing a motor that was noisy, or is it just an adjective they use?

Funny Jerry, funny! lol

You'll notice that there is no :D after my question. I seem to have a reputation as a joker.

Believe it or not, that was a serious question. Did Nikon come out with a motor that is more quiet than the previous one?

Jerry, you do know what the initials SBD stand for, don't you? Silent is silent.

Like the "p" in "psychology"?

Thanks all for the info. I will save up for the AF-S.

Thanks again..

It sounds like an awesome lens. Let us know when you get it and post some photos. Enjoy it!!

Yes, they came out with a motor that was quieter than the first one, which I believe was labeled AF-I.
