Anybody has more information about this objective ?
Is this good for focus stacking microphotography ? I have already Nikon CFI160 10x, but looking something with bigger magnification.
Thanks,
Saul

Note the working distance: 0.57 mm.

This lens would be OK for backlit subjects, but very difficult or impossible to get light around the front of it.

Also this lens is designed for use with cover glass (0.17 mm). At such high numerical aperture (NA 0.65), it would not give a good image if used without cover glass.

Thank you very much, Rik !
Can you give me some link I can read more about cover glass ?
