which ring for 10.5/Subal FE2/2xTC

Hi all, which ring is the best one to use for the Nikon 10.5 in a Subal FE2 port with a 2XTC? I tried the 33mm but the images look a bit soft..

Hi Cor

Sorry can't help you.

Could you explain the interest of using wide angle with a teleconvertor ?

Thanks a lot.

Sven.

Hi Cor,

I use an 8 mm fisheye with a X 1.4 teleconverter in my Olympus housing. It puts a little mors distance between the dome and subject. Image F 5.6 at 1/90th ISO 100. Subject about three inches from dome.

I use the same extension ring I would with a macro port and the teleconverter.
