Hey Brock, I dont know if this is what your problem is or not, but I did a google search and found this ….I guess it is worth a try....

It's a setting.
When using an Ais lens with cpu, as the OP's lens is, it can be used in two ways - either by using the dials for the aperture setting or using the Aperture ring for setting aperture.
The fEE error means, that the camera does not read a "Minimum Aperture position". It's needed when (and only when) you have set the camera to use the (front, normally) dial to set the aperture. To make the camera read that "Minimum Aperture Position" the lens have to be set (and locked, if there is a lock") at the minimum aperture - case solved.
If the camera is setup to use the Aperture ring, there will be no way, the fEE error will occur.
How to set the one or another?:
On the D750 it's the f5 in the user menu - "Customize command dials". Go to Aperture Setting and select the setting you want - "Sub command dial" (ON) or "Aperture Ring" (OFF) - use the OK button to confirm.

Hello guys
I’m going to try too get away from photographic lingo since I believe most people concerned with these issues don’t yet comprehend what photographers are saying - it’s like speaking a different language. To start with say you are looking at a scene and you want to take a picture. You have five people in the scene. You have one lenses a zoom 70-200 FX and you have 2 cameras a DX (crop camera) and a FX (full frame or FF). (note this lenses works on both cameras). You pick up the DX and look through the view finder and see all five people from where you are standing. You don’t want all five in the picture so you get closer so only 3 people are in the picture, take the picture, NOW you pick up the FX camera put the lense on it and without moving or changing the zoom you will see more people then you desire so you will have to zoom in OR move even closer to only see 3 people in the picture, take the picture. The picture will be the same with either camera. The only difference in the cameras is how much of the scene will you see in the picture at the same zoom setting. The FX WILL SEE MORE OF THE SCENE NOTHING ELSE CHANGES!! unless you change it and the crop factor is how much more the FX see of the scene. It’s like the FX has a bigger peep hole to look through then the DX does.


I was reading a little about that and I still need a little more info about DX and FF cameras.

I have a Nikon D3400 with the kit lens 18-55mm, is that a real 18-55mm effect with my camera or do I have to multiply for 1,5?

Do I have to multiply all lenses for 1,5 or only those that are made for FF?

Probably something very easy but I'm a little confused 🤣

Thanks
