Since you asked, my Sigma 100-300/4 is removable. When I use it on a monopod or tripod the mount is used, but when I want to handhold it, I take it off and the lens is more manageable. My Tokina 400/5.6 has one that is not removable. It is more annoying to hold it. So if the options is there, I would prefer to have that capability.
If I had to choose between a non-removable mount or no mount, I would take the mount. Hope this clarifies. -- Best regards, Bruce Sunday, February 11, 2007, 5:00:58 PM, you wrote: >>I agree on it needing to be removable. KW> Inquiring minds want to know why?
