hey guys..
I wanted to ask you what would the difference be between this two lenses regarding sharpness and rendering for full body portraits.

i use the modern 360mm Schneider f6.8 and im pretty happy with it, but i also tested the 210/370 symmar and its also ok.. mybe a bit less sharp.. but ok ... i find the 210 to be abit too wide angle.. so i decided to go for a 240mm

I want to buy a "full body" lens for my 8x10 ..
(for portrait (head and shoulders) stuff im using the 360mm)

thanks for any input.
