Coupling rings.

[dogend]

Hi,

I have a Fujifilm 100mm-400mm with a internal filter thread of 77mm and a 35mm f2 prime lens with a 43mm internal thread of 43mm.

I want to couple these together for some extreme macro shots but I can't find a coupling ring.

Does anyone know where I can find one??

Quite a few places sell 49mm to 77mm reverse coupling rings. Have you considered trying a 43mm to 49mm step-up ring to complete the connection?

That might be the way forward or I may have to try another lens.

I do have the 27mm prime but that is even smaller than than 43mm, I suppose I could try the 16-55mm but that would make the set up too long and would put every thing front heavy especially as I plan to take use a slide and take a lot of shots and then stack them.
