OK looking at different pics of the 28-135 IS and mine, some have "on/off" printed by the switch and others (like mine) have the "l/O" symbols, what gives? What's the difference?

Just something I noticed and was curious about. Bought mine used and thought it might be an older one, but see pics of new ones that appear to be both ways. 7D MKII ■ 10-22 ■ 15-85 ■ 28-135 ■ Σ 50-150 ■ 70-200 f4L ■ 100-400L ■ 580EX II
