Hi!
I am shopping for the Canon EF-S 55-250mm f4-5.6 IS Lens on ebay and I found the Canon EF-S 55-250mm f4-5.6 IS II and the Canon EF-S 55-250mm f4-5.6 IS STM. I do not see the STM on any of the lenses IS II or IS STM some titles say STM and some don't? Am I missing something? And is there a large difference between the IS II and the IS STM?
Thank You
Jeff
