Olympus E-620 : nouveau réflex

Posté le Mardi 24 Février 2009 par Maxime ABLANCOURT

Olympus vient d'annoncer un nouvel appareil photo numérique, l'Olympus E-620. Intégrant directement la gamme réflex du constructeur, l'Olympus E-620 sera commercialisé au mois d'avril prochain pour un prix avoisinant les 700 euros sans objectif.

L'Olympus E-620 est un appareil photo numérique doté d'un capteur Live MOS de 12,3 MégaPixels. Il dispose d'un autofocus 7 points dont 5 en croix, la détection des visages ainsi qu'un système de nettoyage de capteur nommé SWF. Olympus a intégré à son appareil un système de stabilisation interne par translation de capteur. Il sera capable de réaliser des photos dans divers formats, les ratios supportés : 4:3, 16:9, 3:2 et 6:6. Le mode rafale intégré sera capable d'enregistrer les photos à une vitesse de 4 images par seconde.
Sur l'arrière de l'appareil, un écran de 2,7 pouces articulé à été intégré. Cet écran LCD HyperCrystal III affichera une résolution de 230 000 points. Pour la visée, il sera possible d'utiliser la visée réflex et ses 95% de couverture ou bien l'écran grâce à la fonctionnalité LiveView.
Réflex dédié à un public large, différents effets numériques sont disponibles, pour n'en citer que quelques'un, on retrouve bien entendu les différents modes sépia, noir et blanc ou encore un mode pop art et différents modes d'éclairage.

L'Olympus E-620 mesure 130 x 94 x 605 mm pour 475 grammes sans objectif.

7-point Twin AF
A high-speed 7-point autofocus system that uses 7 distance-measuring points, five of which are cross-points, to help determine accurate focus for the camera. It works by using horizontal and vertical sensor lines that form a hounds-tooth pattern to pick out actual focal points and then use the collected data to establish high-precision focus.

Art Filters
Enables special artistic effects to be created directly in the camera. The following Art Filters are available in the Olympus E-620:
Pop Art: Enhances colours, making them stronger and more vivid to create high-impact pictures that express the happy, light-hearted feeling of the pop art style.
Soft Focus: Creates a soft tone which gives pictures an ethereal, otherworldly atmosphere. It renders pictures as though they were veiled in heavenly light, without obscuring details such as the hair or flower petals.
Pale & Light Colour: The foreground is enclosed in flat, gentle light – similar to a flashback scene in a film – creating a sense of déjà vu.
Light Tone: Creates a picture with a gentle feel to it, similar to one taken under artificial lighting. Both the shade and highlight areas are rendered very softly to provide a sophisticated atmosphere.
Grainy Film: This effect recreates the feeling of reality evoked by grainy, high-contrast monochrome pictures. The strong presence and dramatic atmosphere make the subject stand out impressively.
Pin Hole: Reduces the peripheral brightness like an image seen through a pinhole. Added to this is a unique colour tone that results in a style that has an air of secrecy or portrays the feeling of being lost in another dimension or space.

Built-in image stabilisation
A type of image stabiliser that is built directly into the camera. This enables the photo-enhancing effects of image stabilisation to be enjoyed irrespective of the attached lens. In Olympus E-System cameras with built-in image stabilisation, a gyro sensor detects the precise direction of the shake. Using the on-board SWD, the shake is then compensated for by shifting the image sensor according to the movement data. For quick response at long focal lengths, cameras are equipped with two dedicated microprocessors: one to control the two supersonic motors that shift the unit vertically and horizontally, and one to provide high-precision control.

Face Detection Technology
A technology that searches for faces in a composition and recognises them as the main subject. It then automatically puts them in focus and optimally adjusts exposure to create an image that’s sharp in the right places and ideally exposed.

High Speed Live MOS Sensor
A high-performance image sensor that enables Live View capabilities and fast sequential shooting for D-SLR cameras. It combines the advanced specifications of a Full Frame Transfer (FFT) CCD with the low power requirement of a CMOS. Photodiodes are deeply embedded in the sensor to suppress image noise. The faithful reproduction of subject details with rich tones and natural, vibrant colours characterise this type of sensor.

HyperCrystal III
A high-grade, fully-transmissive technology used in LCDs, which employs an additional layer at the bottom of the LCD to reflect light from external light sources. This enhances the brightness of the LCD, so even in direct sunlight images are displayed sharply and with improved contrast compared to that of conventional displays. Also, it provides for particularly wide viewing angles without glare or shadow, so images can be framed from a variety of angles and viewed by several people at once.

Live View
Provides an alternative to framing shots through the viewfinder on a digital SLR camera. The image sent through the lens to the image sensor is displayed directly on the camera’s LCD. Whereas most compact digital cameras have been equipped with Live View functionality for many years, this feature has only recently become available on D-SLRs. The world’s first D-SLR to feature continuous Live View capabilities was the Olympus E-330.

Multi Aspect
The E-620 lets photographers choose from five different aspect ratios that enable individualised framing of scenes. These provide a new means of adding expression to shots and the selected ratio can be seen directly on the camera’s LCD. The available aspect ratios include: 16:9, 3:2, 4:3, 3:4 and 6:6.

Multi Exposure
Multiple exposures are possible with the E-620 in both Live View and viewfinder shooting. In Live View shooting, previously shot RAW data is used as the base image and the final photo can be monitored by overlapping the image to be added on the LCD. Two images can be superimposed in a single multiple exposure sequence.

RC Wireless Flash Control
The user can control wireless flash units remotely – eliminating the need for extra cables – by using the built-in flash as the system’s master unit. Control options include the ability to independently regulate flash mode and compensation settings for up to three groups of flashes, four channel settings to avoid interference as well as a wide range of brightness levels.

Shadow Adjustment Technology
A technology designed to improve exposure for pictures with dark areas. Using a sensor that works much like the human eye, dark parts of a composition (e.g. a shadow under a tree) are identified and the camera then adjusts the exposure settings accordingly for those areas. The result is a more realistic and detailed picture.

Supersonic Wave Filter
Dust entering digital SLRs, for example during lens changes, can cause damage to photos – unless it is removed. With the Supersonic Wave Filter, the potential for dust to ruin photos is eliminated. A transparent filter is located between the camera’s shutter and sensor. It makes sure no dust is able to land on the sensor. Instead, the particles settle on the filter and are then shaken off by a series of ultrasonic vibrations generated by the filter when activated. Olympus was the first manufacturer to incorporate dust protection in D-SLRs.

TruePic III+ image processor
Olympus’ latest-generation image processing engine. It automatically enhances important aspects of image quality including: colour reproduction (colour range, saturation and brightness), picture sharpness (reduced image noise, improved edge reproduction), as well as providing faster processing speeds. Furthermore, it supports Art Filters to enable unprecedented creative expression."
