Tele 1.4 vs. Tele 1.5

Dear Wetpixel,

My "go to" WA set up with my D700 & Aquatica housing is the tokina 10-17mm, 1.5 Kenko tele, Aquatica 6 inch dome port, and the correct Aquatica extension ring (forgot the exact part). With this set up, the raw files have no vignetting, lens/port shades creeping in the corners, etc. The files are clean and don't require cropping. The configuration is perfect.

Anyway, my 1.5 Kenko might be having some problems (I recently got some "f0" readings, indicating no lens attached to the camera = poor contacts).

I thought, ok, very simple, I'll buy another kenko 1.5 tele, but the problem is that it's been discontinued and now they sell only the kenko 1.4. BH, Adorama, others no longer carry it.

Big question: If I buy the kenko 1.4 for use in the same set up, will I get vignetting or part of the dome shade of the six inch Aquatica dome on the raw image?

Many thanks in advance for any possible help.

Very best wishes,

MPO

You will get lens vignetting with a 1.4 from 10-11/12mm with the Tokina, I'm not sure how it will work with your 6 inch port as I use an 8 inch where the port is not the issue just internal lens vignetting.

thanks Jeff. Will see if I find a 1.5 somewhere.
