Re: What does the "G" mean after a lens name?

"G — Designation for lenses without an aperture ring, indicated after the f-number in the name. G lenses retain the mechanical diaphragm coupling of other Nikkors, but the aperture setting can only be controlled by the camera body. Only autofocus bodies with command dials are capable of controlling G lenses. Older autofocus bodies will work with G lenses in shutter priority and program modes with full opened aperture.[2][3] Some recent G lenses feature a weatherproofing gasket around the mounting flange. G lenses otherwise have the same characteristics as D lenses."

They have no aperture ring. Aperture must be controlled from the camera.

Re: Gelded

It means nothing if you're going to put the lens on a DSLR.

However, you cannot use the lens on older film SLR bodies because you will not have control over the aperture. I believe it will be constantly stuck at wide-open.

Re: Gelded

It means that Nikon ripped you off by selling you a lens that cannot be used on old MF bodies. Hopefully, Nikon will come to it's senses and go back to an aperture ring. How much can that possibly cost?

Re: Gelded

pontiac tried to rip me off by offering me an automatic transmission, but i ordered my car with a 6-speed manual. how much more can that extra clutch pedal really cost?

seriously though... considering that the average DX G lens retails for $200, any amount of savings is beneficial if you aren't planning on using a film camera.

combine that with the fact that, even if you are using a non-G lens, the aperture lens cannot be used on a digital camera. it's really just two differing formats. no conspiracy, nobody is trying to rip you off...

also consider this: 100% of canon's EF lens lineup is "G" type in that they do not have aperture rings. they are all 100% electronically controlled...

Re: Gelded

They would be slightly usable (albeit wide open) if that was the case.

But G lenses close all the way when mechanically activated and not communicating with an electronic body.

Your information is incorrect

who told you aperure ring lenses can't be used on DSLR cameras?

"combine that with the fact that, even if you are using a non-G lens, the aperture lens cannot be used on a digital camera. it's really just two differing formats. no conspiracy, nobody is trying to rip you off..."

all of them can be used to some extent and some are fully functional as well
with AF and Metering

Nikon even still sells aperture ring lense's brand new

It stands for "good". I thought everyone knew that.
