Will the Red Sol X Mirror lens work well...
Will the Red Sol X Mirror lens work well in snow?
Yes, the Red Sol X is better for really bright conditions whne it is quite sunny out.
Also, additional lenses--Green Sol X, yellow, amber, etc (for all different light conditions) can be ordered directly from Smith. Recommend you get a Gold Sensor, Gold Light, or RC36 lens for low/flat-light conditions as the Red Sol X lens really works best in bright light (Blue Bird Day) conditions.
