This step ring allows you to attach a standard 58mm filter to a lens that takes 49mm filters. This allows you to have a set of filters that will fit on more than one size lens. Constructed of lightweight aluminum, these step rings are easy to use.
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.
