Hello,
I have a E-PL2 and recently ordered the Olympus PT-EP03 housing with it standard port. Topside I mainly use the Panasonic 20mm f/1.7, which is amazing, but the standard port seems better suited to the 14-42II (which came in the kit, but sits in the cupboard 99% of the time).
Now I had the idea to combine the 20mm with a Zeikos 0.4x fisheye adapter. The adapter seems to be compatible with the 46mm filter thread of the Panny 20mm.
+ 
= ???
But would this combination fit inside the housing with the standard port? How bad would the vignetting be?
If that fails - has anyone tried the combination of Panny 20mm + Zeikos 0.4x inside the Zen dome port? Would it fit? Which dome port would work best?
I know the image quality won't be as good as from the Panny 7-14mm or even the Oly 9-18, but the Zeikos is a lot (A LOT!) cheaper than either.
Any suggestions?
Thanks,
Fred
