A bit of rambling anecdote. Just back from three weeks in Mexico, while on holiday with some exceptions I tend to use a camera to record holiday shots (to the best of my ability) rather than to accentuate the photography aspects. Gear-wise I carry the OM-10, using a Lowepro passport sling because of its non-camera bag look, I use a paracord wrist strap and hold the camera all the time it might be useful. The 12-40 lens sits on it almost all the time, I hate swapping out lenses unless necessary in the field, although in the bag I have the Panny 45-150 for long stuff and the 17mm 2.8 pancake for street photography, two filters for the 12-40, a ND grad and polariser. Means that I am making the best use of the compact factor of the m43, works for me anyhow, I appreciate it wouldn't for everyone.
Anyhow, early on, I had a nasty moment when I thought the 12-40 had broken, as the camera would only set MF. Now there are many who, reading that will immediately realise what had happened, it was early on and I was suffering from jet lag, alright? I didn't. It took me a good few hours to work out that, where I normally have the lens hood inverted on the lens, for and because it is REALLY sunny over there (30+ in the shade all the time....) I was actually using the little b****r. And, yes, of course, putting it into the bag I had knocked the focus ring into MF
At the risk of boring with holiday snaps, here are a couple, straight out the camera (except obv for a basic b&w using google)
