Improved micro photo device
A close up shooting device has improved to rise up magnification, additional external barrel is fabricated and the reverse mounted Triplet lens module was mounted on the tip. It goes without writing that all the inner round surface and radial plate are full covered with no-reflecting scratched black cloth as the same manner mentioned before. But for this kind of lighting noise elimination no good pic is desired at all with good contrast and resolution.
4 mm length is magnified on APSC image sensor with 23.3 mm resulting line expansion almost 6 times and areal enlargement is 36 times as a matter of fact.
A little increase in magnification requires a longer extension of the lens element with loosing focusing depth.
Any way, micro photo world goes without common sense in ordinary shooting, this is why I'm devoted in micro word these days.
A man always wants more, but the importance is to know enough on the way, I know that but my innate bad habit oblige me go ahead.
