Over in another discussion forum, Cosmicnode asked if anyone had tried using a Nikon AF-P 70-300 VR DX lens with a Kenko TC on an FX camera, would it work, and if so, how well?!

The idea of using a tele converter to increase lens coverage is certainly an interesting one, but I was surprised to discover quite how old it was. As far back as the Photokina exhibition of 1970 Sigma was showing a product called the "Imagextender", a 3x converter for fitting 35mm SLR lenses (M42 or Nikon) to Bronica or Rollei 6x6cm medium format SLRs. There's a picture and a little more information here:

As far as I can remember, though, neither this or the 36-105mm f/2.8 zoom lens shown attached ever made it to market...

Very cool! Pity it's literally just a paragraph with no other info.

I really doubted that I invented the idea in my 2016 paper , but I wasn't able to find any scholarly (or otherwise) earlier explanations of it. Not surprising that Sigma would be doing this sort of thing in that timeframe. That's back around the peak of their wildly creative collaborations with Fred Spira and Spiratone.
