I use my Nikon 180mm f/2.8 ED AI-s quite a bit on my GX8 but I really wish the lens had a tripod collar. There really isn't a good spot to attach one so I was thinking of getting the Metabones Nikon F Lens to Micro 4/3 T Adapter II which has a tripod collar. I know you should generally attached a tripod mount to the heaviest object (the lens) but I can't really find a good solution for that problem. I already have the K&F Concept adapter and am quite happy with it but I need a tripod mount.
1. Anyone know of a tripod collar that may work on this lens that won't require machining?
2. Is the Metabones adapter a viable option? Will it support an 800g lens?
3. Any other ideas?
