I have a Kodak z990 Max digital camera and the filter size is not noted on the lens front and not mentioned in the documentation. I figure it is probably in the range of 50-52mm. Can you help? Kodak online help is no help!!
The lens barrel of Z990 should have a 48.5 mm thread. This is not a standard filter size, but looks like some people have succeeded in modifying 49mm filters to fit by filing the thread slightly smaller.
Another option is to use a filter adapter tube, but it seems very likely that the tube will black out corners and edges on shorter focal lengths.
