Indeed. The RPI V2 camera needs to be focused. The hyperfocal distance is 56.6cm, given a 1/4" sensor, f2.0 lens with a 3.06mm focal length. The close focus distance is 28.6cm, far focus is infinity. I use the round cam attachment supplied with my RS camera. I use a focus chart, printed at Costco. http://www.graphics.cornell.edu/~westin ... chart.html
I use Costco as their printers are better than mine.
I've found out of 20 cameras I've purchased, some are just not sharp. Not out of focus, they're in focus, the image isn't sharp.
If you buy, test it right away and return it if not tack sharp. I learned the hard way.
And your question in this ancient q&a topic is...?
