Hi Harriet, Russ, penolta, Les, and Graham,
Thanks for taking a look.
I've attached a couple more shots of the beat up quarter and as requested, a shot of the lens, along with my FA*300/4.5 and FA 50/1.4 as a size comparator, all without hoods. the macro shots were at f6.3 and f14, handheld with the popup flash and diffuser.
BTW, a quarter is a good subject for a 1:1 macro magnification test since it's very close to 24mm wide -- with the APS C sensor at 23.4mm. . .
