Schneider Makro-Symmar HM5.6/180 lens

[sallyaa1]

Any thoughts on the use of this lens: Schneider Makro-Symmar HM5.6/180 lens, for portraiture, though it's mainly designed for copy and close up work? I've used it for some portrait work, seems fine, but I imagine I'm better off using a lens designed specifically for portraiture. Recommendations? Also, I sometimes use my Schneider Symmar-S 5.6/135 for portraits, probably breaking all the rules, but these 2 lenses have served me well, and I like keeping my equipment to a minimum. (Used on a 4x5 wood field camera).
