Carbon Adventurer – Ultrawide Field Camera


The Carbon Adventurer is the brand new, lightweight, member of the Chroma family which weighs less than 1400g (without lens) and allows a photographer to use a wide range of different focal length lenses from 47mm up to 280mm without compromising rigidity or usability. Uniquely, it also has a sliding rear standard to prevent the focusing bed encroaching into the frame when using ultra wide angle lenses.


Like both the Advanced 4×5, and the Snapshot, the Carbon Adventurer uses a bright ground glass to aid critical focusing. The glass is mounted inside a plastic frame, which has a recess built in to allow for an accessory acrylic fresnel to be fitted in order to distribute the light even further. These can be purchased separately from the shop when ordering your camera.


As well as offering even more rigidity than the Advanced 4×5, the Carbon Adventurer is 150g lighter and integrates the unique sliding rear standard for true compatibility. Normally, when using an ultra wide angle lens on a large format camera, it’s not uncommon for the focusing bed to encroach on the bottom of the frame due to the inherent design. To negate this issue, two thumbscrews on the base of the Carbon Adventurer can be loosened and the entire rear standard then slides forwards into its’ wide angle configuration.

In this position, the standard pleated bellows will compress enough to allow the front standard to slide between the rear uprights and mount lenses as wide as 65mm without using a recessed lens board. As the standards are now mounted at the front of the main bed of the camera, the lens field of view should clear the bed. If more movements are required in this configuration, it’s recommended to swap out the pleated bellows for the accessory bag bellows (available in the shop).


The camera can be folded down in less than a minute, without needing to detach the front standard or bellows first. By loosening all adjustment thumbscrews, the camera can also be folded down with smaller lenses left in place (max 20mm forwards from the front lens surround face).


To offer true multi-holder compatibility, the Carbon Adventurer uses brand new design carbon fibre leaf springs and rotating Graflok compatible cams to secure all International Standard holders/backs.

Standard 4×5 sheet film holders are inserted beneath the sprung ground glass, and secured in place using the standard retaining ribs found on all holders. Along with these, the following holders have also been tested to successfully fit beneath the glass;

Fujifilm Quickload

Grafmatic 6 sheet holder

Polaroid 545

ChromaGraphica double dry plate 

ChromaGraphica single wet plate (beta)


For larger holders, the ground glass is easily removed by unclipping two locating pins, allowing those holders to be slid into place and secured using the carbon fibre leaf springs and rotating Graflok cams. This securing method has been tested successfully with the following holders;

Toyo 4/5 69 120 Rollfilm

Grafmatic 6 sheet holder

ChromaGraphica double dry plate
