...I did buy the 55-200 used...
On Six canon camera bodies and on a Sony body I regularly swap lenses without turning off the camera never had an issue, so I wouldn't worry about that
About centering the most practical approach was already posted here by Klaus

What's the issue with your lens ?? what's malfunctioning ??
buying used needs a lot of expertise with lenses, not all sellers are honest and many would be selling because of a malfunction
...well, outside of a slight amount of play in the mount as noted, nothing that I am aware of...
...I have only taken a few images so far but have not noticed any obvious aberrations...joining this forum has made me paranoid... (grin)
...I was a bit leery of a used lens but I thought it would be obvious if there was anything wrong with it... (d'oh!)
...Andromeda seemed like a good bet...all the used 55-200's sold out quickly...
...I was a bit put off by the number of used 55-200 lenses @ Adorama, (3) but they were gone in a day...
...I paid $500 for the "E" rated one and was only slightly discouraged by a weird, fine, deep scratch on the Zoom ring...it other wise appears new...
...as I type this there are no used 55-200's, but there are three used 18-55's, and a "V" (very good) XF 90 I wish I could grab @ $679...
...I am sure it will be long gone by the time I am flush...
...I am hoping a used 10-24 will show up when I am watching (and flush)...methinks it might be a long wait...
...the last time I saw a used 55-18 there it sold in hours...open box or demo grade is like 46% off retail...they seem to have a brisk trade in used lenses at Adorama...
...right now I have $2708.69 in my cart...LoLoL...
