Manual aperture lens questions

I have a question for those who have used 3rd-party manual aperture lenses on Canon bodies. Have the lenses you've used reported nothing (f-stop is "00"), or have they reported the aperture selected? Have any of the lenses communicated enough with the body to allow TTL viewing and metering wide open, or are they always stopped down?

TIA.
