Frankly, F:2.8 and 1/500s under the conditions you
describe sound pretty much correct to me both when using the sunny 16 rule
(compensated for overcast light) and based on my experience (eg. my 600/4 at
F:4.5 in sunshine for a medium toned subject yields approximately 1/1500s with
100ISO film). It all also depends on the tonality of the subject but definitely
doesn't sound off beat to me.
It perfectly normal that the aperture isn't
displayed when using an "A" lens with manually set aperture. My Z-1p do
this and I guess the ZX-5n does the same.
You really have to give us more details in order to
spot the problem; I'm not all convinced that there is a
problem. Switch to spot metering and set the
set both camera and lens to "A". Then select aperture manually and select the
value that the program line choose. Then compare shutterspeed; they should be
the same. Then change to another lens and meter the same area with the same
aperture and compare results and tell us what you find.
