MINOLTA MD 16mm f2.8 Fisheye Lens Instructions
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)
These tutorials originally appeared on a now-defunct Japanese website. A German website dedicated to the Minolta manual focus system had copied the pages and kept them online after the original Japanese site closed up, but the tutorials were written in Japanese.
We’ve translated them into English and are posting them on the Learn Camera Repair website so that they’ll be available to English-speaking users, and to keep them available if the German site ever goes dark. You can see the original Japanese versions on the Minolta SR Site: http://minolta.eazypix.de/index.html
The 16mm fisheye
compared to a Minolta standard lens
Use a spanner
wrench to remove the ring with the Minolta name together with the front lens
unit. It unscrews counterclokwise.
The
front lens group and name ring, now separated from the lens barrel.
Turn the lens over and remove the rear lens 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 by unscrewing it counterclokwise.
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 can be scratched easily.
The red arrow indicates the built-in filters.
