No, it's not there 

Hi. Yes it is suitable , in fact , that's the very camera I'm using it on. It rather depends what you mean by 'fully'. The camera will not use any of it's auto features because the lens is totally manual , there is no metering and also the focus aids don't work. However , the camera takes pictures with a tamron lens perfectly well . Set it to 'M' on the dial and then set your own shutter speed and aperture . It will look a little dark through the view-finder ( at least it does on my 135 telephoto lens ) but the pictures come out fine . 

Yes, the lens cover is threaded, it can be screwed on directly, or it can be magnetically attached by a magnetic attachment ring or filter, which is a two-in-one function; 

Thanks for your reply, i have several AF nikkor lenses. 24-120 mm 3.5 and 50mm f1.4 and 85mm1.8 

Yes, the lens cap has a thread. The lens can be screwed on directly or attached with a magnetic mounting ring or a magnetic filter. It has a two-in-one function.
