Just because they were at hand.
No processing applied to the wider shots, some sharpening applied to the close-ups, to maximise their potential. G9 used and the 17mm was pulled back an inch to match magnification, but it was not quite enough.
The Oly is slightly warmer, but that is known.
My claims of different Bokeh rendering, may be over stated. I tested these once before and felt I perceived, without prompting, a real difference there, but in this situation, the 17mm seems to be more Bokeh empowered. The “heavier” look is there though and the mechanical differences are also still relevant.
At f2.8 they are both close to their best, showing every hair and even paint texture.
