Hybrid Solution

The Contax 645, a robust system familiar with many for its unique look, beautiful lenses and it’s mechanical reliability.

Primed for digital, the Contax 645 is the perfect hybrid solution for photographers shooting 120 film but needing the flexibility of digital to help expand what they offer.

With a Phase One digital back, expand your flexibility with the digital convenience in the same great system you know and love.

Digital: Keep Your Film Look

Thanks to the amazing processing behind Capture One Pro we have been able to develop custom film profiles for the most popular films. Maintain a seamless workflow with the benefits of digital without losing the look you are known for. Custom profiles available upon request with purchase. 

Easy switching from Film to Digital

There is a place for both in today’s modern photo industry and the Contax 645 makes that collaboration seamless.

Switching to digital from film and back again is as easy as attaching a new film magazine. Simply attach the digital back, hit the On button and start shooting.


Use your Contax more frequently with less film processing, retouching, shipping and wait times. Get images to your clients faster, save time and money.

Dynamic Range
The extreme dynamic range of the IQ3 Digital Back range (up to 14 f-stops on the IQ3 50MP & 15 f-stops on the IQ3 100MP) enables you to capture nearly every scene no matter what the lighting conditions. Bring back virtually every detail, even if you didn’t get the exposure perfect at capture.

Unmatched color
The IQ3 Digital Backs are built to ensure you capture images with smooth and subtle transitions, reproducing the scene as perfect as possible. IQ3 Digital Backs make this possible by capturing images with up to 16-bit color depth per channel.

Leaf Shutter Advantage
With an integrated Leaf Shutter, the range of Schneider Kreuznach lenses delivers industry leading flash synchronization speed of up to 1/1600th of a second. Photographers can overpower daylight and gain complete control over ambient light using flash to create beautiful lighting effects.

Built for robustness from the ground up.
Phase One Systems have been used for decades in some of the most demanding professional applications. With the XF Camera System we have upgraded all moving parts and materials, delivering the fastest, most robust and most reliable camera system we have ever made. The XF Camera System was created to be a universal platform that is fully integrated with Capture One, offering complete control.

100 Glorious Megapixels
IQ3 resolution of 50MP, 60MP, 80MP or 100MP not only delivers incredible detail, but also provides creative flexibility, accommodating virtually any application requirement, be it print or digital.

Wireless Built-In
Wireless communication is an integrated part of the IQ3 Digital Back range allowing you to connect an iPad or iPhone wirelessly and use Capture Pilot (downloadable in the app store) for Live View, exposure control, shutter release and instantly check focus or compose on a larger screen.
