Hasselblad has updated its aerial camera offering with a new model that features a 100MP sensor. The A6D appears to have replaced the A5D series, which had a number of sensor options, with a single body using the company’s highest resolution back. The new model has many features similar to the previous incarnation and allows synchronization of up to eight cable-connected bodies with a delay of just 20 microseconds.
The use of the 100MP sensor increases the system’s dynamic range from a maximum of 14 to 15 stops, and the company has installed a slot for CFast 2.0 memory media.
Hasselblad has nine H lenses that have been adapted especially for aerial use. With focal lengths from 24mm to 300mm the system offers angles of view of 96-10.2° and a new top shutter speed of 1/4000sec. Hasselblad says that because its lenses use leaf shutters they are less exposed to issues of the plane’s movements than focal plane shutter systems that can only compensate for motion in a single direction – usually forward.
The A6D will be available with or without an infrared cut filter so it can be used with sensitivity to extended wave lengths of 750-1000nm. For more information see the Hasselblad website.

Hasselblad Introduces a 100 Megapixel Aerial Camera System
Aerial photography delivers better results today than ever before and Hasselblad continues to grow its presence in the market, introducing more advanced products and applications for the aerial photographic industry. This is reflected in the Hasselblad A6D-100c, the latest evolution of Hasselblad aerial cameras.
Hasselblad cameras are developed by building on the shoulders of the previous generation of models which enables all of the prior advancements and branch-demanding features to be automatically included. This process allows Hasselblad to continually enhance and develop models. The A6D heralds a technological improvement that is noticeably greater than earlier generations.
The A6D Aerial camera includes a feature that allows up to eight cameras to be synchronized within 20 ?s. A simple bus-type cable connection is required between all cameras in the set-up. This feature completely eliminates any issues in post-production caused by un-synchronized exposures.
Product Manager Bjarne Hjörlund commented, “Available in 100 megapixel resolutions, the A6D camera combines the world’s best optics and sensors with a modern, compact design, resulting in a system that will ensure you attain the highest possible image quality. Hasselblad aerial cameras provide a range of important features that help deliver your imaging requirements”.
Nine H System lenses are available in aerial versions with secure locking mounts to minimize vibration and flexing which guarantees the image plane and sensor stay parallel at all times. These units ship with their focus precisely adjusted and fixed at infinity. The focal length range from 24 to 300mm of these lenses results in a horizontal AFOV of 96° to 10.2° covering most applications. The new generation of leaf shutters for the H lenses has an extended lifetime, which ensures reliability during flight.
In addition, the exposure time for the aerial lenses has been improved up to 1/4000 of a second, for sharp and crisp images. Traditionally, FMC systems typically only compensate for movement in a single direction, but the fast leaf shutter-based exposure time can both compensate for ground speed and the roll and pitch of the plane.
Near Infra-Red Photography
The A6D camera is available with or without Infra-Red filter for infra-red captures from 750nm to 1000nm to serve the needs of aerial analysis, such as environment surveying and crop management. NDVI, CIR and NIR imaging is possible with third party software.
Phocus SDK by Hasselblad
To facilitate the development of user specific software, Hasselblad offers a complete Software Developers Kit (SDK) which allows full control of camera and image processing from the user’s own software. To quickly get started using the A6D aerial cameras for photography, Hasselblad has created a simple but effective PC sample application which can capture and store RAW files coming from the camera. All source code for this application is supplied to allow the user to adapt to special individual requirements.
