DukeP, Los Angeles:
The LAEA5 works wonders on a Sony A7R iv. Now A mount lenses work 99% as good as the E mount native lenses. I put the Minolta 100mm macro f2.8 and it works just as good if not better than it did on the A99ii. The same goes for the 70 300 G. I didn't like the LAEA4 but the 5 is on a whole nother level. It's not bulky like the LA EA4.
