Olympus E-30 Lens Mount
By Mike Flacy
4/3 Lens Mount
The all-metal lens mount for the Four Thirds System is twice the diagonal measurement of the imager. With this lens mount the body size, lens size and overall weight are reduced.
Digital Specific 'Smart' Lenses
Olympus Zuiko Digital Lenses are designed so light strikes the camera's image sensor directly, ensuring rich, accurate colors, sharp contrasts and bright images even at the edges.
Lenses that are smart, that talk with the camera about their specific optical designs and imaging information. Lenses, particularly zoom lenses have some distortion. This is true of all manufacturers. Zuiko Digital Lenses store data in the header portion of the digital file allowing for software-assisted correction of anomalies including pin cushion and barrel distortion.
Shoot wide open or stopped all the way down and achieve superior results over 35mm film based lenses. Zuiko Digital Specific Lenses are about three times the resolution of ordinary film based lenses.
The Smart Lens Design allows users to shoot with the most current firmware versions of each particular E SLR System component. Update the camera system using:
Zuiko Digital 14-54mm Kit Lens
The 14-54mm (28-108mm 35mm equivalent) lens features has a minimum focusing distance of 22cm throughout its entire zoom range. The 3 aspherical glass lenses give you high image quality and resolution. The f/2.8-f/3.5 allows more light to the image sensor, increasing your top shooting speeds in lower light shooting conditions.
Zuiko Digital 25mm, 14-42mm, and 40-150mm
The Zuiko Digital 25mm f2.8 is a thin, lightweight single-focus standard pancake-type lens. The lens has an overall length of 23.5 mm. When combined with E-410 or E-420, the total length including the camera body and lens is only 76.5 mm. The result is an easy-to-store, easy-to-carry camera system with go-anywhere portability. With a focal distance equivalent to 50 mm on a 35 mm film camera lens, this lens provides an image angle very close to that of the naked eye. The result is a near-natural visual field that makes this an ideal standard lens for daily use, whether for simple snapshots or for more sophisticated portrait and landscape shooting.
The Zuiko Digital 14-42mm f3.5-5.6 (equivalent to 28-90mm in 35mm photography) is a 3x standard zoom lens is the smallest and lightest in its class and features a closest focusing distance of only 25cm. The ED (Extra-low Dispersion) and two aspherical lens elements correct aberrations without increasing lens dimensions. The circular aperture diaphragm enables beautiful defocusing - one of the big advantages of this lens.
