The focusing rail is an essential accessory for macro photography, that requires precise focusing as well as other situations where accurate camera positioning is crucial. Two 6 rails allow movement in all four directions. The 1/4-20 thread fits most tripods. Positive locking knobs assure rock-steady focus. The excellent quality rail is for use with all Digital and Film SLR cameras.
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.
