Hasselblad H4D-40 Medium Format DSLR Camera Kit

Digital Lens Correction and Ultra-Focus

The H4D-40 camera allows information from the lens and exact capture conditions to be fed to the camera processor for ultra-fine tuning of the auto-focus mechanism, taking into account the design specifications of the lens and the optical specifications of the sensor. In this way the full HC/HCD lens program is even further enhanced, bringing a new level of sharpness and resolution. Digital correction for color aberration and distortion is also added. Digital Lens Correction (DAC) is an automatic correction of the images based on a combination of the various parameters concerning each specific lens for each specific shot, ensuring that each image represents the best that your equipment can produce.

True Focus & Absolute Position Lock (APL)

True Focus helps solve one of the most lingering challenges that face serious photographers today: true, accurate focusing throughout the image field. Hasselblad has used modern yaw rate sensor technology to measure angular velocity in an innovative way. The result is the new Absolute Position Lock (APL) processor, which forms the foundation of Hasselblad's True Focus feature. The APL processor accurately logs camera movement during any re-composing, then uses these exact measurements to calculate the necessary focus adjustment, and issues the proper commands to the lens's focus motor so it can compensate. The APL processor computes the advanced positional algorithms and carries out the required focus corrections at such rapid speed that no shutter lag occurs. The H4D's firmware then further perfects the focus using the precise data retrieval system found on all HC/HCD lenses.

Instant Approval Architecture

Building on the success of the Audio Exposure Feedback technology, Hasselblad has created Instant Approval Architecture (IA), an enhanced set of feedback tools, designed to enable the photographer to focus on the shoot rather than the selection process. IA triggers audible and visual signals for each image captured, notifying the photographer immediately of its classification status. The information is recorded both in the file and in the file name, providing a quick and easy way to classify and select images, in the field or back at the studio. IA is a Hasselblad trademark and Hasselblad has a patent pending on the invention.

Tethered or Un-tethered Operation

The H4D-40 provides the ability to combine working tethered and un-tethered to get the most of your camera system both on location and in the studio.

Processing Options

This Hasselblad allows the option of processing your raw images in Hasselblad's Phocus imaging toolbox, or working with your raw images directly in Apple or Adobe imaging environments.

Meeting Commercial Challenges

Using the H4D-40 gives you the choice of combining point-and-shoot and tilt/shift to solve creative commercial challenges. Two basic options are available for tilt/shift work with H4D-40. A simple-to-use, portable adapter solution and the classic view camera solution. The HTS tilt/shift adapter for H4D-40 allows for portable tilt/shift with the HC/HCD lens range from 28mm to 100mm.

Two Modes of Operation & Storage

The H4D-40 offers a choice of storage devices: CF cards or a computer hard drive. With these operating and storage options, you are able to select a mode to suit the nature of the work in hand, whether in the studio or on location.

Other New Features

Expanding on the great feature set of the H3D camera line, a set of new camera features are introduced with the H4D-40:

• Camera electronics delivering the basis for True Focus and ultra fast Auto Focus
• Extra large 3" display on the H4D-40 provides a realistic, high quality and perfect contrast image view, even in bright sunlight
• Extended exposure time up to 4 min (256 sec) exposure
• AF assist lights for working in dark environments
• 80 MB/sec read-write performance on Extreme Pro cards from SanDisk

Phocus 2.0 Software

Special Extended Camera Controls

Special extended camera controls with which to operate your H4D-40 camera. These features, such as live video for easier shot set-up and workflow, or the ability to control the lens drive for focusing when the camera is in a remote position or when the digital capture unit is mounted on a view camera, bring an entirely new level of flexibility to the way you shoot.

Moiré Removal Technology

Moiré Removal Technology automatically applied directly on the raw data, leaving image quality intact and eliminating the need to carry out special masking selections or other manual procedures, saving hours of tedious post-production work.

Flexible Workflow

The Phocus GUI features easy-to-use options that allow you to customize your set-up to suit a range of different workflow situations, such as choice of import source, browsing/comparison functions, file management, image exporting a number of file formats, pre-setting of options for upcoming shoots, and more.

New Metadata

The extended metadata included in all Phocus images provides for accurate and detailed cataloguing and indexing, easy image management, and includes added GPS data functionality in order to allow a range of new functions. Phocus links GPS data directly to Google Earth, for example, making geographic reference a snap and image storage and retrieval much easier.

100% Viewing Quality

The Phocus Viewer delivers image viewing quality that matches every detail of what you will see later in Photoshop. In addition, the Phocus Viewer allows you to customize layout and composition to suit your current or desired workflow, providing a wide range of options including full view, compare, browse, horizontal, or vertical view, and so on. You can have multiple folders open simultaneously for side-by-side viewing, comparison, and selection.
