<p>Agreed Shun, its not the best or ideal position to lay the lens at but sometimes while changing to another, I have found that its the most convenient position while I attach another. Usually less than a minute, between my feet and then its into the case. </p>
<p>Incidentally, when I first got the lens a few years back I managed to drop it! This was while holding the removable tripod collar (which had not been tightened) and accidentally pulling the trigger. Luckily it was on carpeted floor, and not too great a height, but it is a testament to the outstanding build quality of the lens. </p>
