Thanks all for your responses.
I decided to enable geotagging for my photos and use OsmTracker for
tracking (1 sec interval). Then I load the gpx file and the photos into
JOSM where I put the POIs into OSM. Yesterday I marked in a bit more
than 200 POIs and today might bring in rougly the same amount.
So far, so good.
