The Hasselblad H4D-40 Medium Format DSLR delivers unsurpassed image quality via an outstanding set of powerful features and precision optics.The H4D-40 features a 40 megapixel medium format sensor and True Focus with APL (Absolute Position Lock), refining the auto-focus system for accurate composing at close range with shallow depth-of-field.

The features of this camera meet the needs of professional photographers while on location or in the studio. The low noise color filter of the H4D-40’s sensor provides for increased clarity and increased depth of field. The Natural Color Solution (HNCS) achieves consistent color reproduction using a single color profile, and digital lens correction perfects each image captured through HC/HCD lenses by removing any trace of distortion, vignetting, or chromatic aberrations.

The Hasselblad HC 80mm f/2.8 is the standard lens for the H system. The high-performance design ensures great color correction, a flat image plane, and low distortion. The wide aperture facilitates photography in poor light and provides a bright viewfinder image. A lens suited for almost any task in general photography.

The H4D also comes bundled with Hasselblad’s Phocus 2.0 imaging software, featuring a dramatically reduced learning curve, enabling the average photographer to be up to speed in less than 30 minutes, and a feature set that matches the industry standards defined by Adobe and Apple.

The H4D-40 takes full benefit from all the flexibility of the impressive H camera system. Photographers get a camera that is as easy to use and delivers the image quality professionals expect from Hasselblad.

Features

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

True Focus: Delivering accurate composing at close distance with shallow depth-of-field
True Focus helps solve one of the most lingering challenges in professional photography, true, accurate focusing throughout the image field when working with shallow depth-of-field at closer range. Without multi-point auto-focus a typical auto-focus camera can only correctly measure focus on a subject that is in the center of the image. When a photographer wants to focus on a subject outside the center area, they have to lock focus on the subject and then re-compose the image.

In short distances, this re-composing causes focus error, as the plane of focus sharpness follows the camera’s movement, perpendicular to the axis of the lens. The traditional solution for most DSLRs has been to equip the camera with a multi-point AF sensor. These sensors allow the photographer to fix an off-center focus point on an off-center subject, which is then focused correctly, but such multi-point AF solutions are often tedious and inflexible to work with and do not really solve the problem.

To overcome this problem, 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 page 3/3 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. The True Focus technology and APL (both patent pending) mark a significant milestone for Hasselblad’s high-end DSLR strategy and represent the result of many years of development work.
