Modifying a 49mm UV filter to fit the Z990 48.55mm lens
Dec 1, 2011

Here is an interesting thread in a Taiwanese forum with many images. You do not need to understand the Chinese language to read it. You need to click the URLs inside the posts to see the images.

It reports an interesting DIY project by a Z990 owner to modify the screw threads of a 49mm UV filter to fit the 48.5mm lens of the Z990:

The crux of the Taiwanese post is as follows:

Work around the 49mm filter's circumference, use a finger file to rub down the screw threads of the filter. Be patient. File a bit at one time and then try to fit the filter into the 48.5mm lens. If still too tight, file a little more. So on and so forth. Do not be too ambitious and file down the filter a lot in one go. This may lead to too loose a fit. In the end, a nice fit is achieved. There is no need to use any super-glue. There is also no need to file the rim of the 49mm lens.

Hope the above summary helps forumers who cannot read the Chinese language!

Further information regarding the lens cover discussed in the Taiwanese thread:

(1) One user bought an OEM lens cover for the 49mm filter. See the images in the post by "bill36112000" at the bottom of the thread.

(2) Another user filed down the two shutter arcs of the Kodak original cover. He also filed down the rim of the 49mm filter to shorten its height. See the images in the post by "asawang" near the bottom of the thread.

I suppose he was having problems with vignetting ? That is interesting, I have a polarising filter for the P880, but at full wide angle,there is slight vignetting, grinding down the filter could be a solution... thanks for posting this !

So there are 48.5mm threads on that lens, or is he just making the filter a "push fit?"

No, thread on the barrel. It is a push fit. They just file down a 49mm to 48.5mm.

Hi. olympus c5060wz cameras have a 48.5 filter thread, they are still available on e/bay.

They should fit without modification
