>>3607355If you need that single stop, I recommend getting the Tele-Elmarit-M. As you want to use it as a portrait kit, the Elmar-C probably won't satisfy you in the long run.
I barely use the 90mm and it's ok that it's only f/4. Does it have to be a 90mm? I strongly recommend the 50mm Summicron if you're going for portraits. I does magic wide open.
