[edit] can a filter interfere with a lens light metering properly?
try to use your lens 100/2,8 in non-A setting, e.g. at f4. In case you have aperture block failure, pictures will still be good, not dark, because aperture will not go beyond f4

BTW if you have aperture block repaired earlier, the failure can repeat because solenoid that was replaced can be the same bad quality as first one.
