Minolta MD 16mm f2.8 Fisheye Disassembly Tutorial

Easy disassembly method for lens cleaning (mold removal)

Difficulty ★★★☆☆

 

Things to prepare

  • JIS cross-point precision screwdriver
  • Spanner wrench. The one shown here is a homemade tool
  • Kitchen rubber gloves
  • Blower or compressed air
  • Lens cleaning paper
  • Lens cleaning liquid (lens cleaner)

 

Compared with standard lens.

 

With a spanner wrench, remove the ring with the Minolta name together with the front lens unit counterclockwise.

Turn the lens over and remove the rear cap.

 

If you remove the four screws on the lens mount, the lens mount will come off as a unit.

Note! When the aperture ring is lifted, it will come off, but at this time the spring of the click stop will bounce and the tiny bearing will tend to go missing.

 

Grab the rear lens unit with rubber gloves and remove it counterclockwise.

 

Clean with lens cleaner and paper. First, don't forget to blow off the dust with a blower!

The front and rear lens groups sandwiching the aperture are in a "unit structure" housed in a metal tube. The lenses facing the outsides of this unit are hard coated, so it is okay to clean them, but if you disassemble it, the lenses on the inside are soft and scratch easily.
