Ricoh GX100 street test photo #3. After shooting a few dozen shots in auto-everything mode, I started using the camera's manual controls. Manual focus allowed me to shoot faster than AF, although the MF controls were not exact. Using the up/down buttons on the circular array of control buttons on the back of the camera allows you to focus in approximate increments. One press brings you from infinity down to 3 meters, then to 1 meter, then focuses in smaller increments down to 1cm. The longer you press, the more the focus changes, but it's not an exact science, and this was frustrating when shooting on the streets.
I ended up locking focus midway between 3 meters and 1 meter and let my rough estimate of the hyperfocal distance do the heavy lifting.
