Often while under the focusing cloth, a photographer wishes to simultaneously adjust tilt/rise/fall and focus while critically observing the ground glass with a loupe. This is never easy; it is a true challenge to keep the loupe flush with merely the pressure of your head while still maintaining comfortable eye relief and not fogging everything up from the stress. But Wista's sliding focusing loupe adapter solves this problem brilliantly. It attaches to the focusing screen frame and can be moved freely horizontally or vertically on the surface of the focusing screen. This hands-free magnifier is supplied with the focusing frame and base for Wista's 5x loupe, so one must install a ground glass and optional Fresnel lens. This is designed to ensure accurate focusing and to enable both hands to be used for minute adjustments.
