Using 1.4x TC to convert APS-C lens to FF sensor?
Aug 10, 2014


I wondered here, that could 1.4x (or 2x) teleconverter be used as APS-C lens to FF converter (like opposite focal reducer)?

I have very nice Sigma 50-150/2.8 zoom (apsc lens) for my apsc A65 camera. And with Sigma 1.4x teleconverter it's like 70-210mm f/4 lens...Anyway, (my question is) do you think/know that 50-150/2.8+1.4x combo could fill the whole FF sensor without too much vignetting? After all, Sigma 1.4x TC is FF compatible converter.

My plan is to get FF camera in the near future, maybe I could use this combination with it...
