What size Extension tube on HC 80/2.8 Portraits

[rollsman44]

  I want to buy 1 Extension tube for portraits to use with my 80/2.8   Which one will work for me and not have to worry about compensating for exposure?  Thank you

I have used a HC 26mm extension tube for exactly this. I sold my H gear some months ago but I still have just this extension tube for sale. Looks like new. Please send pm. if you are interested.

I would actually recommend the 13mm tube. I think the 26mm would be way too close.
