One Actus to do it all
Steve Hendrix produced a fine write up about the various Actus models. We gratefully published it at our new website. It’s certainly not our intention to start a sequel. However, with a new Actus version available it is time for an addition.
The Actus-DB2. has always been the dedicated Actus model for use with Digital Backs. And if you prefer to use one at the same platform as your Mirrorless or DSLR, a digital back frame like this ACDB-989 fits onto the Actus-G. The Actus-DB2 remained the Actus of choice for Hasselblad en Phase One shooters though, since the Actus-G is misaligned when a Back is attached to it. Inevitable due to the latter’s form factor. Use with bayonets has priority here, use with a Back is an afterthought.
There’s an Actus which can do it all and do it all right. The Actus-G990D (for Phase One) or Actus-G991D (for Hasselblad) come with the rotating back adapters as shown above. Digital back and lens are aligned. Now wouldn’t the Mirrorless camera you’d also like to use on this platform sit too low? The solution for this is using the bayonets designed for the Actus-MV view camera.
Here the Actus-G990D is shown with an IQ4-150 digital back. The Rodenstock lens has a Phase One X-Shutter. The rear frame is detachable and can be replaced by a bayonet holder if needed. Cambo offers one for virtually any camera. This version of the Actus is the platform that accepts every sensor, from M43 to Phase One IQ4.
