Great Kit Lens
By DKizzy
Like a previous reviewer I was confused about the lens shooting position message. I was coming from a Sony A6000 where the stock lens would just boot up and be ready to shoot. On this lens, you have to turn the lens until it reaches the 18mm position and then it's ready to shoot. Took me one google search to figure it out, so I have no clue why he complained about trying to figure it out for two hours. Anyway, I hope this helps out some other beginners!
