Actually, it does. It means that the mechanical control is not very good, that's all, not even for wide open at different FLs.

Sorry, no, it doesn't. The mechanical lever pulls the aperture wide open when mounted to the camera, regardless of the focal length (and of course I checked that visually, too). Works with almost any lens I have, only two exceptions: the Tamron Di 60 (currently at Tamron Europe again) and now the 70-300 VC.



And even if the lever was the reason: since the lever is not moved during exposure for wide open shots, the metering should at least be correct in this case.



Edit: actually, the metering should be correct in any case. Moving the lever to stop down might lead to under- or overexposed shots (see 70mm/f8 above), but the metered values should be correct. Unfortunately, they are not.



Another Edit: forgot one lens, that has expsoure issues on Nikon, too: the Voigtländer 20 SL II.
