True, that's why a more careful choice may be required. The 46mm Heliopan tele hood is fine on the Leica 90mm Elmarit, yet the Contax hood (G3 I believe) is a bit more intrusive, although I don't think (can't remember) if even it intrudes into the 90mm frame line. Plus, as Rob noted (and you pointed out when first introducing me to Heliopan hoods some years ago) the stacking feature allows some room for optimization (two short hoods may work better than one long hood, for example).
