Disclaimer: I am a n00b with a Panny GX1 who mostly shoots in automatic mode. I am sure that everything on this list is old news to all of you. 1. You will never be able to carefully compose photos when traveling with your spouse, four kids, and a tour guide. Attempting to do so will irritate everyone. 2. Using the 14-42 kit lens is almost not worth it when the 20mm is so darn sharp in comparison. My ten year old daughter even told me to just shoot and crop later. 3. You know how you self-righteously mock those guys with expensive Canons and 70-200mm lenses that look like giant codpieces? Well now you're at Yala game reserve, and all of the cool animals are really. far. away. So now who's laughing now, smarty pants? Also, it's quite dusty, and those Chinese tourists wearing surgical masks are perhaps not as silly as they seemed. 4. You told yourself you don't need a viewfinder, but really, you need a viewfinder. It is just too bright most of the time and not having one for those times hurts the composition. 5. Yes, taking 300 shots through the glass of the touring van window is kind of stupid, but five of those photos are AMAZING. 6. If you take 1700 photos over nine days, you are going to spend three months sorting through them all. So anyway, I'm in the market for something with a viewfinder, and I am definitely getting a longer lens for my next trip.
