Congrats on the kit. From what I've read, a lot of people don't shoot with the aux. lens just because their not really wide or tele or worth the trouble.
I've shot with them once, and I found the experience to be very fun. Well, it was fun times to begin with. I used a cable release shutter and just started snapping every so often during a get together at my house.
Here's 2 examples.
I have used the Oly XA (a 35mm, wider than the aux wide) for similar instances with the timer, but the damn beeping it makes while counting down caught too much attention. The cable release shutter was slightly more incognito
Have fun with yours. I plan on using mine more.
