I shoot 4x5 and currently only have a 210mm Rodenstock Sironar-N---this is the only lens I have experienced with 4x5. I'm needing a wide angle lens and am looking for suggestions. I don't want a wide angle lens that shows any typical wide angle distortion-----perhaps a lens that stops just short of that. What are some suggestions (I realize a bag bellows is going to be needed)?

Thanks
Chuck
