I mostly do photography using Nikon gear. When it comes to video I use the Panasonic GH5 and adapt my Nikon lenses via adapter. The adapter does not have any electronics. So I'm stuck to manual focus (which is perfectly fine) and also I can't change the aperture of the Tamron 70-200mm G2 since it has an electronic aperture.
When I use the Tamron 70-200 f/2.8 on this body it gives me an equivalent of an 140-400mm f/2.8 (which is awesome!). However I'm thinking whether I should get the Nikon TC14E II teleconverter for my photography stuff. I came across the question if this teleconverter would work on my Tamron 70-200mm without any controls just for the extra reach. I know that Nikon's TCs are only made for a couple of Nikon lenses and they might not work with the Tamron lens on my Nikon body - but would they work on the GH5?
Remember, I don't need any autofocus, vibration reduction or aperture control to work since the camera can't communicate to the lens anyway. I just would need to this a manual lens with more reach.
Would that work?
