Hello All, Does anyone have Depth of Field charts for 58mm, 100mm, 180mm Sonnar and 270mm lenses? I have one for my 80mm Planar that I assume is similar to the 100mm chart, but has anyone access to the others?

You can get software on-line for calculating depth of field for any lens you like at https://www.dofmaster.com . The make or construction of the lens does not matter - basic optics tells us that the depth of field and depth of focus are functions of focal length and diaphragm opening only.
