G1XII f/2.0: Macro vs. longer distance
While running my G1XII through its paces I saw for myself the effect of using the widest aperture at close range (~5 - 10 cm). At this range, it seems f/4 is a maximum. I've seen some mention of this in my reading. But, what I haven't found yet is any info on a "safe" working distance for f/2. Is there a subject distance for which I can expect much crisper focus?
