First, remove the front and rear lens caps from the lens.
Remove dust from the exterior of the lens body.
Wipe the body with a towel using anhydrous ethanol.
Remove dust from the front lens.
Use anhydrous ethanol and wipe with silvon paper.
Remove dust from the rear lens.
Use anhydrous ethanol and wipe with silvon paper.
Remove dust from the lens mount.
Use anhydrous ethanol and wipe with Silvon paper.
Wipe the front lens cap with anhydrous ethanol and silvon paper.
Wipe the rear lens cap with anhydrous ethanol and silvon paper.
Check the operation.
Check the movement of the focus ring and shutter release.
Finally, attach the front lens cap and rear lens cap.
Cleaning and operation check are completed.
The mount of this lens has a K mount, which is a switch from the M42 mount.
As time went by and autofocus and other features came out, it became more difficult to use the M42 mount, so they switched to the K mount.
Overall, this lens is beautiful.
Both front and rear lenses are also clean when viewed normally, but there is a haze or fog-like substance in the lens when exposed to strong LED light.
I think this is conversely a tasteful depiction.
If you are interested in these lenses, please get them!
