Olympus M.Zuiko Digitial ED 14-150mm f/4-5.6 II Lens
- It has a compact design:
- 63.5 mm (2.5 inches) max. diameter,
- 83.8 mm (3.3 inches) length with
- a weight of 283 grams (10 ounces).
- There is ZERO (ZUIKO Extra-low Reflection Optical) Coating on the surface of the lens to eliminate scratches as well as reduce ghosting and lens flare, even in very bright situations.
- A dustproof, splashproof lens construction uses 15 individual lens elements in 11 distinct groups.
The lens design includes DSA (Dual Sided Asperical) lens, Aspherical ED (Extra-low Dispersion) lens, ED (Extra-low Dispersion) lens, and three HR (High-Refractive index) lenses with high spherical aberration correction capability.
DSA element corrects aberrations as well as offers a compact and lightweight body.
- This technology makes it possible to reduce the size of the lens but requires high-precision fabrication technology due to the extremely large ratio of thickness between the center and periphery.
- The development and fabrication of this DSA lens would not have been possible without expert design, measuring techniques capable of precise surface accuracy evaluation, advanced ultra-high-precision aspherical surface molding techniques, ultra-precision assembling technology, and polishing skill honed through years of experience at Olympus.

The new M.Zuiko Digitial ED 14-150mm f/4-5.6 II has a lavish lens architecture, providing outstanding image quality throughout the 10.7x zoom range. Of the many special lens elements employed, the Dual Super Aspherical (DSA) lens, first mass-produced by Olympus, greatly contributes to keeping the lens compact while delivering top-class image quality.
The DSA lens has a huge thickness differential between the center and periphery of the lens, which requires lens mold precision two times that of standard lenses, in addition to super-accurate measuring equipment and computer programs to make sure each lens element produced is perfect (see video). And to prevent the DSA lens from cracking as it cools down during the molding process, Olympus developed its own heat control technology, controlling the temperature of the mold and lens by the degree even at temperatures up to 600°C/1100°F.
Backed by such technology, and with a splashproof/dustproof construction and ZERO (Zuiko Extra-low Reflection Optical) Coating, the M.Zuiko Digitial ED 14-150mm f/4-5.6 II proves to be a truly magnificent lens.
