I have a 205FCC and want to take portraits (just of the head or even closer) of my children. I have both an 110FE, 150 FE and an 80 CFE. Also have extension tubes 16E, 32E, 56E that I could use with either but would use the 80 CFE. I would want good depth of field to have everything in focus. What would be the difference in effect in using the 110 close up alone compared to the 80 with the short extension tube. My desire is to have a very close up of the face with it taking up most of the negative. My plan is to enlarge it to 16x16 using 16x20 paper.
