Hi D,


The ballhead will be fine for temporary use, especially for smaller lenses such as the 100-400mm lens. What I was describing seems to be more of a problem with heavier Supertelephoto lenses, when you loosen the ballhead knob, the lens tries to find its own center of gravity, within an uncontrolled spherical plane. In other words it flops downward and to the side simultaneously.


As far as the 234RC (Quick Release) vs. the standard 234 tilt head, I prefer the non quick release regarding Manfrotto because it feels more stable and solid to me.Ialso really prefer Arca Swiss style releases.The mouting platform on the standard 234 is also wider and it's cheaper too.
