●There is no difference in the optical performance of lens quality between DCR-6600PRO and other HD-6600PRO models.
●Exposing the conversion lens to a warm atmosphere in an instant way from the cold area may create some dew on and inside the lens. When it happened inside the lens, keep the lens in a dry area till the dew disappear before using. Repeating such may leave dirt spot - (mildew) and affect the image.
