A73 & A7R3? Advantages & Disadvantages?


Some of the differences (apart from resolution and price) that I have heard so far and that favor one or the other body:

Better AF for A73 (A73 has 693 PD & 425 CD points covering 93% of screen; A7R3 has 399 PD & 425 CD covering 68% of screen----see Guys post above)

A73 has better IBIS by half a stop (5.5 vs 5)

No anti-aliasing filter for A7R3

DXO sensor score of 100 for A7R3, 96 for A73; DXO reports same DR (14.7) for both, better color dpeth for A7R3 but A73 has better low light score

Bill Claff shows about one-quarter extra stop of PDR for A73 over most of the ISO range

A7R3 has 3686K-dot EVF; A73 has 2359K-dot EVF

A7R3 has 1440K-dot LCD; A73 has 921K-dot LCD

A7R3 Max Native ISO = 32000; A73 Max Native ISO = 51200

Best site for comparing specs that I have found is Imaging Resource, but there are probably other good ones:
