there is a new lense from smith that changes the color for different light condtions. a guy from smith told me about it and said that it takes about 30 seconds to change over. ive been seeing in new mags.i think its called the sensormatic lense. i also have another guy tell me that the lense is a spoof and doesnt change in different light but is really just a good lense for low light conditions only? anyone know the deal?
