Ever notice how 35mm half frame users comfortably shoot in portrait orientation much of the time. While full frame users seem to favor landscape. Not sure why but for decades I’ve had both Pen F and OM systems and find myself doing that. I’ve speculated it may be because of the difference in ratios, 3:4 is shorter than 2:3, numerically not a big difference but visually very much so, to my eyes at least.
