They are mediocre at best, owners say. I know some people that have one they use as secondary cameras (for multi-angle setups), but they bought it first, got disappointed and bought something else, this is the path.
I own an old Pro 9000 and it's still respectable. Only its FPS is a little low but, it was the king of the hill when I bought it.
As I've looked now, it seems that they discontinued ones with Zeiss lenses. The ones with Zeiss lenses were both low light and clarity monsters for their size.
Their highest model is Brio Pro with 3D sensing it seems. I need to see its performance. However Logi says it has a real glass lens so it shouldn't be a slouch.
Nevertheless, it's not fair to compare a lentil sized sensor with a Full 35mm, last gen mirrorless.
Of course a bigger sensor and a bigger lens (DSLR, Mirrorless, etc.) is something different.
