The New Projection Lens
Result of several years' research and product of a house which has made the highest-grade lensmaking a specialty for nearly 70 years. Gives brilliant illumination and is unequalled in flatness of field — crisp definition — and sharp contrasts between black and white. Offered in two series, as illustrated, and absolutely invariable in quality.
Series I: In fifteen focal lengths, from 4 to 8inch ; cannot be surpassed for the average theatre work.
Series II: In ten focal lengths, from 5% to 8inch; just the lens for large auditoriums, where long throws are necessary, and should always be used with Mazda lamp outfits.
