As mentioned in at least one other thread the weird matrix of higher shutter speeds not being available at wider apertures is a mite frustrating, esp without a built-in ND filter. On a bright day I have to stop down quite a bit (in M/A modes) to avoid overexposure. I'd like to get an ND filter (2-4 stops ideally) that I could carry around and attach easily, but would like to avoid the bulk of a 52mm thread adapter. I carry my X10 in a wrap-around case so anything extra has to be small enough to leave on (ideally!) or if carried separately, be easily attached/detached each time. What solutions have others found to attach ND filter to their X10? Any other solutions to work around the shutter speed limitations?
