• The viewfinder design is similar to that of a rangefinder camera, resulting in a
slight deviation between the viewfinder and camera lens. The actual captured
image may appear slightly lower than what is seen in the viewfinder. Shooting
technique: Align the subject within the viewfinder and slightly lift the bottom of
the camera by about 5 degrees for the best results. (Fig. 1)!
What is the resolution of the camera? !
• The camera has a 1-megapixel wide-angle lens with a DFOV of 70 degrees. It
also comes with an ISP for professional image processing. It delivers good
imaging results when capturing subjects from a distance of half a meter or more.!
