Please review the Nikkor micro 105/2,8 VR! It's not a zoom, but from the specifications I would assume, that it's pretty powerful: An aperture of 2,8 plus the famous VR technology. That must be a killer qualitywise, when it comes to close ups (up to 1:1)...
Plus show us a comparison with close-up lens(es) and expanders, as they let us combine the flexibility of our current lenses (e.g. the fantastic 18-200 VR) with close-up!
