How does the aperture control ring function? Is it indexed in some way? Or is it simply setting the lens aperture fully open or fully closed?

not indexed at all, but can stop between the 2 ends (fully open & smallest aperture) --- have often used the middle position for the range of f5.6~11 and got sharp results.

Yes. Zoom and Focus are manual with the inner ring for the later. It s a little bit to freaky not so gradual control. Its endless so no physical connection with lens I guess.

Some high-end lenses have focusing ring that can be pulled back into a MF only mode. If this is the case simply push the focus ring forward. Otherwise, press the AF button (above the on/off switch) and use the left and right direction buttons until S-AF is selected.

you use this one with manual OM lens and it has the aperture control that you controls iris via the that aperture ring on you OM lens

It allows u to step the aperture up or down.. It does not declick the aperture for a continuous fluid aperture, that would require a modification to the lens itself.

when I use my reverse mount ring or make the following settings f8 1/250 my kit 18-55 lens at 55mm, as is a G-type lens, there is a metal pin which placed a small paper pedaso to maintain the aperture fully open. this pin is moved from right to left in the inner edge of lens.I hope I've been helpful.

It has two controls for zoom, and you can use either. One is in front of the shutter release, and the other is on the lens. You change to manual focus in the menus. There are no control rings on the lens.

The Fotodiox Aperture control isn't a reversing ring. It doesn't do anything that a reversing ring does. A reversing ring attaches to the front element of a lens to allow you to mount the lens backwards. The Fotodiox Aperture control attaches to the rear element of a Nikkor G-style lens to allow you to set the aperture (since the G lenses don't have aperture control rings) when the lens is mounted in a reverse position. You'd buy this because, presumably, you already have a reversing ring on a G lens and want to be able to control the aperture of that lens when it's mounted in the reverse position.

Based on my use of the camera, You can 'set' the aperture in both Aperture priority and Manual modes. Otherwise, the camera will choose the best to properly expose the shot. You can 'force' the aperture where you want it to go by adjusting the ISO, ND filter, etc... but if you are concerned primarily with aperture, you should probably be in A priority or Manual mode.

I have found it only to be a slight adjustment. If you take it off the camera then move it in front of something close to focus on. Adjust the ring and you will see a slight difference. Personally I don't use the diopter after initial focus.

No what full time manual focus means is you can correct the focus as the focus ring stays connected and you can override auto focus at any time after it has locked focus, however as I have never had any pictures not pin sharp from this lens relying on auto-focus I never have to use the manual focus ring, the lens snaps in to focus first touch of the shutter every time, just wish my other lenses were as good as this one at getting it right when you need it, best 300 on the market IMO, much prefer this to the 2.8 version.

Dear, Yes, I have the same problem. The only way to open & close the lens is with the switch on & off botton. KR

No, aperture is controlled manually. FD lens cannot be controlled automatically.

The lenses are manual zoom, so you turn the ring on the lens itself. If you have a prime lens, like the 30mm, there is no zoom.

I don't know but I don't think that you can do anything but manually focus with these lens babies... they are not designed to autofocus so there is a bit of a learning and experimenting with them till you get the look that you want....each aperture ring gives you a slightly different look... so you have to know where to direct your focus.. and that has to be done manually....

Yes, limited functionality: no AF, no metering. Aperture can not be adjusted electronically. So if your lens doesn't have an aperture ring, you can't change the settings.

Thanks for the explanation, Les. So, it seems that as long as the IS is turned on, in-camera, it doesn't matter whether it's on or off on the lens. I made do some A/B testing to see if there's a difference with the lens switch on/off while the setting is switched on in-camera.
