I agree with most of the "improvement needed" comments but I use the built in ND filter in my X100 and the X10 does not have this feature. As there are times that I want to shoot wide open in the bright light and/ or with off-camera flash, an adapter is necessary to hold the ND filterHoya 52mm HMC ND8 Multi-Coated Neutral Density Filter. This adapter allows for the use of filters. As the Fuji adapter was not available at the time of my X10 purchase, I bought the Aftermarket hood adapter sold on Amazon. (I have the same brand adapter for my x100). The aftermarket is almost exactly the same with a few minor differences. The aftermarket does not match the camera finish, the adapter threads are slightly longer to fit deeper into the lens barrel and it does not come with the carry pouch. (I uploaded pictures for review.) The color mis-match is not noticeable on the X100 but the all black x10 does look better with he Fuji adapter rather than the aftermarket part. The lack of lens cap is a hassle and there is some viewfinder blockage but if your photography leads you into creative shooting with the X10, it's the only game in town. BTW, i paid 59.99 from Amazon, any more than that and out of principle I'd have to overlook the gloss black finish and get the aftermarket for 29.99 EzFoto 52mm Filter Adapter + Lens Hood for Fuji X10, 100% replaces FUFJIFILM LH-X10.
