Here is a high quality, black anodized aluminum Step Up Ring made in JAPAN. This is for mounting a 55mm filter or hood on a 48mm lens front ring. Step up/down rings like this are a good idea. Filters and hoods can be very expensive so these rings save you a lot of money. I like having the ability to use all of my filters and hoods on all of my lenses.
ExpoDisc, the original white balance filter gets even better. Set white balance, meter for exposure and dust map your sensor with the only calibrated and certified 18% transmission incident light metering filter.
We invented the digital white balance filter with the original ExpoDisc and established it in the market as the premium white balance tool by individually testing and certifying every ExpoDisc. Now, ExpoDisc 2.0 introduces user-selectable warming filters (gels), an improved mounting design, and a new lower price-point.
