Mamiya lenses are designed and built for todayâs foremost photographers who expect their equipment to provide both outstanding and distinctive results. Engineers at Mamiya have developed rigorous performance criteria for each lens design. No detail is overlooked. No test is omitted. The goal is technical perfection... The result is a series of lenses which have set the new world-standard of performance. Each lens element is precisely polished and coated using Mamiyaâs proprietary multi-coating process to increase light transmission, dramatically reduce flare, ensure crisp, clean whites and vibrant, yet natural colors. Mamiya engineers and inspectors test continuously as the lens is assembled to insure flawless quality. The result is a lens designed so carefully, built so meticulously, that it consistently renders extraordinary performance. It is Mamiyaâs unique balance of extreme sharpness, brilliant contrast, accurate and consistent color fidelity and overall high performance that captures the imagination of contemporary photographers who choose Mamiya to express their personal visions. Among todayâs community of world famous photographers, Mamiya lenses have established themselves as the new benchmark by which others are measured. While all Mamiya lenses can be used on todayâs high performance digital backs, the new Mamiya Sekor D series of lenses raise sharpness to a new level. Utilizing exotic Low Dispersion glass and Aspherical lens elements, the Sekor D Digital Lens series produces ultrawide coverage (28mm f4.5), exceptional color accuracy and sharp, contrasty images. And all Mamiya Digital lenses are designed to work with film backs, not only digital backs!
