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.

Subject: Lens communication problem?

Quick question:
 
I picked up an "ugly" but optically good A* 400mm f2.8 and was testing it out today.    One thing I noticed with it on my ZX-5n was some odd metering.
 
With the camera in manual focus, and Autoexposure, and the lens at 2.8, it was selecting 1/500s (this was in overcast skies on 100 ISO, so definitely an underexposure (it didn't matter if I switched to spot metering, so the meter wasn't 'confused').   If I set the lens to A, the camera selected f4.5 and a 1/60s exposure (looked right to me).
 
Also there was no indicator of the F-stop in the display, just --.
 
Thoughts?  Am I screwed?
 
TIA,
