I'm wanting to know what lens would be better for a tight head and shoulder shot. I realize both are heavy and large. Will only be used for indoor portraits with flash on a 4x5 camera. On a 6x6 medium format I liked the results of a 200mm. I like the more compressed image. I have 395mm of bellows but can add extensions if necessary. I get about f32 with 100 ASA out of my flash units. So I'm trying to decide between 300mm APO Symmar vs 360mm APO Symmar. Naturally both are used.
