Pentax W30 Panorama Mode or Exposure Lock?
This camera is fun! I have not encountered any focusing problems, it is just a little slower if it's dark.
I did a focusing test last night, indoor with limited light, out of 10 attempts, on average, it took 2 seconds to lock the focus.
I dont think the camera has AE lock or Panoramic function. It has an MF focus mode though
