Last month I bought a DC as $3XX HKD low, it has 300Mega pixels. The ratio
of quality over cost is not bad, I like it. Taking the wide object is OK
but close is bad like far-sightedness.
The far-sightedness is that the image is behind the film. The problem
is how to make image on the film. So I add the convex lens to solve this
problem with low cost. Adding more powerful lens can take as small SMD
component as possible unbelievably.
Placing convex lens in front of the camera can take the closing object
as simple as left side picture.
More convex lens can take more closing object
sharply.
Taking your own risk. |
