My Olympus e-m5 arrived while i was on the TGO, and i just got the panasonic 12-35mm, so now i have a weather sealed camera + lens.
I prefer using 12+25+45mm primes but for hiking in Scotland ill take the weather sealed zoom...
Its been only 2 months, and one of my feet isnt yet completely healed but i am already considering trying to do TGO 2013 :p
