I pulled my back the day before my daughter's birthday party. I knew that if I did not take pictures there would be like 1 or 2 total because my wife is just too busy talking to the other parents. So, I didn't want to carry my K-5, grip, and lens selection to the party and aggravate my back. But, because I own a Q there was an easy solution.
The Q 01, 02, and 03 all together weigh in at ...well...functionally nothing...and my back was happy AND I have lots of photos of the kids at the party.
Why do I own a Q? More reasons every day it seems.
