Hello,
Has anyone tried the new sony 70-350 APSC on a full-frame a7 series? For some of the APSC zoom lenses, the image pretty much covers the entire full-frame sensor when fully zoomed. I would use this lens on my a7r3 at 350 all the time for bird and small wildlife, so bad vignetting at shorter focal lengths is not an issue, and slight vignetting at 350 is also OK. I hike a lot, and the 100-400 is just too heavy!
