My Xperia 1 III used to be quite disappointing at times (was too focused on RAW output for editing, even stacked HDR shot RAWs) but the 1 V is legit good and I can tell the new sensor stacking improved light capture (less noise in low light) and auto mode is much better, while I still see limitations both in auto and manual it’s not so bad. The most annoying parts have to do with focus and color balance when zooming in certain light conditions, and contrast in complex scenes in auto mode.
