I'm getting into 4x5 for the first time with a Graflex R.B. Super D 4x5. I have a 190mm lens on it now, but I'm looking for a suggestion for a portrait lens. I want an old-timey soft look. I'm thinking maybe an old brass lens. Also, what's the widest lens I can use on this camera? I'm also looking for a developing tank suggestion for B&W processing. Thanks in advance.
