The modification described by Fred is only to a lens cap. The whole adapter removes easily just like the original lens cap did, so you keep all the full features of the 17mm TS-E lens, and do not modify it. And if you start with a spare lens cap, which only costs about $40, then you still have the original cap to use. |

But the Lee 82mm Wide Angle adapter is actually made from two metal parts, which look like they have been screwed together with thread lock or epoxy to hold them in place. If you could remove the inner metal part that provides the 82mm threads, it would open up the adapter to a hole size of about 86 mm. One possible way to do a removal is to use a small grinding tool and carefully remove one portion of the inner ring. If you can get one short portion removed, the rest may come out easily by prying, because of the gap you have made in the ring. This is similar to cutting the metal of a stuck filter to get the remaining ring out of the lens. In this case, it does not matter if you slightly damage the threads on the outer part, because you are not using them for this project. If cutting one short section out does not work, you can cut out a second section opposite from the first, and then the two parts should be much easier to remove. I must warn that I have not yet tried this, but it looks very practical to me. It is also a much easier do it your self project than machining. |

The extra 7 mm of diameter should in theory give about an additional 2.5 mm of available shift before problems show up, so consider that as you decide how to proceed. |

Basically by removing the thread ring, you gain 7mm as illustrated on the picture below: |

I will post some pictures of the entire set-up once I unpack today. My gear got all salty and dusty. |
