5x Powermate Vignetting?

I posted this in the TV forum, but thought I'd ask here as well. I wouldn't even consider putting this in the eyepiece forum as no one would ever look there ;^) .

I have a set of recent TV plossls and want more magnification. I am considering the 5x Powermate, the 2.5x Powermate, and the 3-6mm TV zoom. Ignoring cost and number element considerations, I'm merely wondering if the 5x Powermate can be used with the all the TV plossls without vignetting. If so, then it appears that I'll be able to add effective FLs of 6.4mm, 5mm, 4mm, 3mm, 2.2mm, and 1.6mm. That would be great, though I'll probably never use 2.2 or 1.6.

Otherwise, the other options are worth considering. What do you recommend?

Thanks.

I use the 2.5x PowerMate a lot and there is NO cut-off with a 32mm Plossl or even a 20mm, 70* AFOV Widescan. I borrowed a 5X to check the same thing and it was still fine (full field) with the 20mm Widescan and a 25mm Ultrascopic Plossl. Didn't try the 32mm. I'm considering the 5x also now.
