So I did what you should never do and took an untried camera oiut to a job.
I was covered to an extent shooting an EM1.2, EM10.2 and the S5II, but still, I had not even tested to see if C1 would open the RAW files!
Setting the camera to area focus (large central box, easily expanded), with human detaction activated and the 20-60 on, I got about a 90% hit rate capturing early learning children on an outdoor orientation day. This is basically a free for all of a dozen different activities spread around the school parkland, the kids allowed to wander and experiment as they choose.
It is fast, frantic and fantastic.
See-shoot is how I work in these situations and this combination felt natural, definitely more sure footed than the G9.1 I would usually use. I bought the S5II for stills and video, knowing it would do both a little better than the S5 Mk1, but not sure by how much. Looks good.
I shoot most of these images with a longer lens, then move in close and wide. In the past the 17, 15 or 8-18 have been my chosen lenses for this, but the S5II and 20-60 were excellent.
