Title: Hidden wonder or waste of technology?
Post by: Akira on January 05, 2018, 04:40:50: There have been some buzz about the hidden wonder of the Japanese official New Year's greeting card.

The red lines right above the numbers "0" and "8" of "2018" seen below left in the image #1 are actually not the simple red lines but the greeting message of Japanese "Happy New Year".

Yeah, I know. The lens was an RMS mount Zuiko MC Macro 38/3.5.

The quality of micro-printing on our bank notes are much better. These letters are printed on the post card and not that clear.

This is a Japanese post card for the New Year's greetings. Japan Post officially prints the cards designed for each year based on the Oriental Zodiac.

What is your experience with the Zuiko MC Macro 38/3.5?

On today's hi-res sensors, its optical quality is so-so. Its preset aperture is handy. I bought mine for 9,000 JPY, so it's good enough for casual closeups at 3-5x. The working distance at those magnifications is around 2cm, which makes the lighting easier when necessary.

For serious works, you may want to look for Macro Nikkor, Zeiss Luminar, Mitsutoyo, etc.

Add 2cm seem to be a very reasonable working distance, considering the magnification.

Indeed it's a fun lens.

Correction: the working distance was even longer. Here is a table showing the relationship between the magnification, extension and working distance (I also have the table for 20/3.5 and upload here as well):
