I thinking of stepping up to 8x10 wood camera and will use 300-360mm barrel lenses for portraits. I found Deardorff a little bit to expensive and also a bit risky buying used. I like the look of Tachihara better then the Shen Hao and also the price is lower. My only concern is if the Tachihara 8x10 is sturdy enough for barrel lenses 300-360mm? Would appreciate all help/ experience regarding this!
