Both are normal lenses. You are looking at 150mm and 180mm equivalents on 4x5 or 45mm and 55mm equivalents on a 35mm camera or full frame DSLR. The 210 you are using would be like the 420 that E. suggests.
Yousuf Karsh used a 14" (360mm) and I read somewhere that Richard Avedon used a 360mm Schneider on his American West portraits. You can check them out if you want examples.
I own a 14" Commercial Ektar but I have also tried a 300mm lens. There isn't a lot of difference in focal length.
