What a terrific, inspiring thread. Good thing too, because I just bought this lens today. After Christmas I bought the KP, my first new camera body in 8 years (a companion for the K-5 which I am keeping). It's probably been 6 years since I've bought a lens and I really needed a wide angle zoom. I have a 16-50 which is decentred and such a heavy beast that I never use it. I debated the DA 18-135 which I had a chance to borrow from a friend when I was in Sydney last year and, for a day at the harbour, it was good but I was not blown away (which was probably partly due to me not the lens). However after looking at all the reviews I decided to go a little higher and get this one.
Hopefully it will be warm enough to get out with it tomorrow and I'm very excited about taking this new combo to Kolkata next month.
Thanks for all the inspiring images. I'm feeling a little less guilty for my splurge.
