This 1-1/2 to 1-1/4 pvc threaded converter/reducer is from Loews for $1. The larger, front inside diameter is ~ 49mm. A 49mm step ring or filter casing will fit tightly. The tolerance of pvc fittings is not very close so it could be a little loose (fill the gap with electrical tape) or it could be a little tight (file/sand away a little pvc).

The inside diameter of the threaded end of the pvc fitting is very close to the diameter of the base (larger) section of the fx01 lens extension housing closest to the camera.

Remove the threaded portion of the pvc reducer with a hack saw at the base of the taper. The inside diameter of the base needs to be enlarged to fit over the fx01 extension housing. Shortening the taper increases the inside diameter. This can be done fairly easily with sandpaper or better yet a grinding wheel. I just rubbed it against a rough concrete sidewalk. A cinder block would work. Remove a some pvc and check to see if it will fit over the extended housing. When it does, clean it up with sandpaper and leave that end alone. As you can see, I removed about 1/8" up to the embossed lettering.

The pvc fitting is still too long. Leaving it like this will place the filter too far from the fx01 extended lens. You need to remove 1/8"-1/4" of plastic by rubbing against concrete or whatever. You want to shorten it to where the extended lens is approximately flush with the front edge. With the 49mm step ring or dummy filter inserted this will insure that the extended lens will not touch the filter. Here is the final product with a 49-55mm step ring inserted. The second picture is with a 55mm hoya r72 ir filter connected. The adapter is handheld over the extended lens against the front of the fx01. I had planned to mount it somehow to the tripod hole but this setup works very nicely as is. And the fx01 can quickly resume its life as the ultra-compact it was designed to be.

Obviously, this setup will work with other light weight filters such as polarizer, nd, close-up lens, etc.

Geez, should have read this post first. Now I know how you did the filter. Very clever and Rube Goldberg would be proud of of you.



P.S. For anyone not familiar with Rube, just ask Seemolf. He is a master.

Update for a more permanent arrangement.
It aint purdy but it works. Additional material needed: (1) 2" mending plate; (2) a 3/4" long round head 1/4" stove bolt with washer and nut; and (3) a 1/2" long 3/16" round head bolt with nut.

Drill one of the holes in the 2" mending plate bigger with a 1/4" bit. Attach that end to the tripod hole with the 3/4" 1/4x20 stove bolt and a 1/4" washer as a spacer between the mending plate and the tripod hole and a 1/4 nut as a spacer between the bolt head and the mending plate. (*The main purpose of the spacer nut is for storage later.) Place the pvc adapter over the extended lens and shift the mending plate so that the smaller hole lines up with the middle of the pvc adapter side/bottom. Mark that, remove the adapter, and drill a 3/16" hole there in the pvc adapter. Remove the mending plate from the tripod hole and attach the smaller hole end to the pvc adapter with the 1/2" long 3/16" bolt. Then reattach the other end of the mending plate to the tripod hole with the 1/4" bolt. You may have to bend the mending plate some to get a good alignment. The stepring may interfer a little with the mending plate. I had to cut off a corner of the mending plate.

In stored positon. *The spacer nut holds the bolt and washer together with the mending plate for storage.
