There is some slight coating peeling, but it is usable.
It probably won't significantly affect the captured images, but I'm mentioning it just in case.

■Easily achieve close-up shots just by attaching it to your lens! For macro photography beyond the lens's minimum focusing distance.
No.3 is recommended for lenses with a minimum focusing distance of 30-50cm. The effect is minimal for lenses that already have a short minimum focusing distance.

A close-up lens is a close-up accessory that allows for the easiest close-up photography simply by attaching it in front of the lens.
Since the amount of light does not decrease, the shutter speed does not become slower.
