Konica 28mm f3.5 Hexar AR

Although minor dust and scratching won't affect image quality, major defects like haze, fungus, or separation cause decreased sharpness and contrast. We inspect every lens and provide cleaning & repair when appropriate. Otherwise, we clearly state any flaws in lens optics in our product descriptions.

Our skilled team of technicians also work diligently to ensure that our lenses have appropriately functioning mechanics. They test focal throw, zoom, aperture stop-down, filter threads, and all applicable electronic functions (like autofocus).

Our collimator is used to simulate infinity focus for the purpose of ensuring lens alignment & focus at any distance. We also use a special high-contrast target board to ensure that rangefinders are properly aligned both vertically & horizontally.

Many lenses require extra work beyond testing & checking. Our mechanics are able to repair lens diaphragms, calibrate focus, adjust helicoids, and install spare or replacement parts as necessary.
