As has been pointed out by several people, there was the 250mm f/5.6 Sonnar for Linhof. They also made the equivalent Sonnar for the Baby Technika, a 180mm f/4.8. The latter covers 140mm wide open, so it is quite close to 4x5 coverage and stopped down does cover 4x5. Zeiss also tried a few more Sonnar prototypes for LF, such as a 250mm f/4, or a 300mm f/4 (that one for 8x10). You can find the information on LF Sonnars on pages 13-17 of my recent article on Zeiss Oberkochen LF lenses: http://www.arnecroell.com/zeissoberkochen.pdf
