am looking at getting the 100mm and at a later date putting my 1.4 teleconverter on it ,is it possible to get only 1 modular port for both 100mm on it's own and the 100mm and converter together, the teleconverter makes the lens 20mm longer would using a port 20mm longer make any difference to the optics and frame coverage? and if ok which port extention would i need to do both? PS:-looking at the AUTO only port extention, any info would be appreciated
