Anyone have info on identifying these two lenses by just a photo? Serial nos?
The one I am considering just has a "T" on front and serial no. Beginning with 719...
Thanks for any help!

C will have Synchro Compur shutter and Bay-50 filter mount.
C will also have interlocked shutter speed and aperture.
CF will have Prontor shutter and Bay-60 filter mount.
Well, CF lenses say CF on the side next to the focal range. My CF has a serial of 6763701 and says "Carl Zeiss Sonnar 4/150 T* 6763701" on the front, with the T* in red, and the rest of the lettering is in white. So the one you're looking at is probably a CF lens if the serial is 719****.
C lenses can be black or chrome, with or without T*. As Nick said, easiest way to distinguish them is by the shape of the barrel. C: focussing ring and speed ring have scalloped edges and the whole lens becomes narrower towards the front. CF lenses have a diamond-grid style rubber on the focussing ring.
