I've a very nice 620 Monitor with a "special" lens and a slightly sticky flash kodamatic shutter. Works at all speeds & timer but there is noticable "deposit" on shutter blades where they overlap. Slow to open; not "snappy". The inside lens (from the front) has only a tiny hole to aid removal. Does it turn clockwise to remove? Do I need a secret Kodak tool? Hate to bung it up. Maybe someone knows how to get this lens fully dis-assembled or would share some pages from a repair manual. |

You need a flexiclamp (search at micro-tools.com or make one yourself out of plastic). Make sure to carefully measure before you buy a flexiclamp to get the correct size. AFAIK, that little hole is not used when you disassemble the shutter.
Do not use pliers to unscrew the second lens element, you may guess how I know that... |

Bought the flexiclamp(macro-tools has lousy customer service), soaked the shutter most of the winter (it's too cold to work in my unheated shop), messed around with the damn thing several weeks, finally got it working this weekend. It never worked so good!!! "I get by with a little help from my friends"
Mounted it on a board for my baby Graphic. Ready to give it a side by side test with some others before remounting on the Monitor.
The next question: Is there a "sweet spot" or should I get maximum performance from it with it set at infinity? It's a "SPECIAL". Actual focus will be on the ground glass of the Graphic. |

Sweet spot = infinity at f11.
Or f16 if it is the bigger 616 film Monitor. |

Foto_gaga: please notice the 4 years gap between the post you are responding to, and current date...
Nonetheless, archives are enriched this way, just don't expect Puderse to respond ;P

There is only 28 minutes between the post and the response. I think you are looking at Puderese's date of registration. |

As to the sweet spot, I believe lenses on consumer cameras of this vintage had their sweet spot at maybe 15 feet distance, where you'd take a group shot. |
