Other factors you might like to consider, should they affect your operation of the lens, are:

“Does the lens extend when focusing?”
“How easy is it to switch from auto focusing to manual focusing?”

The length of some macro lenses remain fixed throughout the focus range, whilst for others, the lens grows substantially when focusing towards the closer distances.
