Let's try this again, with some words this time.

I was thinking about the new K1 and having to use my 16-85mm in crop mode. I mounted it on an older film body and there shows some vignetting of course on the corners at all focal lengths but none at all with the Tamron PZ 1.4 Teleconverter. I know that it probably isn't a 100% viewfinder but interesting to me and I'm looking forward to trying out on FF. With the TC it looks like it would be about a 22.5-119mm lens, albeit slow and degraded IQ.

So lets assume that the usable part of the image equates to 1.5x ... now you get a 24-128mm F5.3-8.4 ... sure if you were happy with it on APS-C then all you're really gaining on FF is more pixels for less detail, If you APS-C body was the 16mp type then there is no benefit, if it has more pixels then there is even less benefit... there may be some lenses that are worth converting in this manner but i don't think this is one of them
