Recently, DSL cameras has magnifying function prior to shooting on the back LCD. It is very helpful in focusing situations especially for geriatrics with poor eyesight. Also, it taught me how I did it appropriately. I feel shame to have talked about Lens resolution, contrast and sharpness, physical property of optical system.
Now I feel that focusing cannot be too much however precisely it might be done.
In addition, DSL including DSLR cameras could be regarded as an optical inspection equipment if the datum are checked on PC condition.
On the other hand, pixel peeping habit is not always a good manner to evaluate transparencies, because human eyes has also the capability to resolve the object. The more distance from the object, the less resolution it has.
In other words, Botanical precise drawing is not always evaluated from a distance, however precisely it might be done, it is invisible from a distance.
Energy & Power of the object are the second to none.
A picture shows the modified lens, avoiding spherical abrasion reversely mounted for close up shooting, from old silver salt period toy camera, Konica Hexanon 38mm/2.8.
Exaggerated and expensive device is not always required for closeup shooting, an alternative cost only 300 yen.
