Chroma Cameras’ 679 camera system turns medium format modular

20 Nov

Chroma Cameras has unveiled a modular medium format camera for shooting 120 film. The new 679 camera system allows customers to custom build a camera for their specific needs.

Speaking to Kosmo Foto, Chroma Cameras founder Steve Lloyd says, ‘The Chroma 679 is a brand new, modular, medium format camera system. Like my other Chroma cameras, it’s been designed around the idea of flexibility and ‘uniqueness’, along with being an affordable, and enjoyable, way to combine existing lenses and film holders.’

The Chroma 679 system comprises four standard components. All 679 cameras use a laser cut acrylic front plate with integrated metal helicoid. The next item is a custom threaded lens board constructed using anodized aluminum. This screws into the front of the 679 helicoid to create a secure mount. There are two styles of lens board available, a standard Copal and a 0.4mm brass pinhole.

The third component is the mid-body. This is the primary body section of a constructed 679 camera. It creates a spacer to mount the lens the correct distance from the film for obtaining infinity focus and it includes a pair of cold shoes. You can use cold shoes for accessories such as a light meter or a viewfinder. The mid-body is also the mounting point for optional accessories such as a tripod mount or full grip. The mid-body is available in any depth from 10mm up to 120mm. If you need help determining which mid-body depth you require, refer to this page.

The final component is the film back. There are four mounts available: Kiev88, Mamiya Press, Mamiya RB Pro S and Hasselblad V Series (early version only, which allows manual winding of film without a Hasselblad body). There is also an available plain ground glass film back.

These standard components connect using a physical interlock and four ‘very strong neodymium rare-earth magnets’ in each section. Additional accessories can also be attached using integrated mounting points on each side of the mid-body. Photographers can purchase an additional cold shoe plate and a basic tripod mount to add to their 679 camera system. Further, there’s an available full grip with an integrated tripod thread, internal storage for a roll of 120 film, and a passthrough mount for a cable release. The grip is available in black and wooden printed materials for either left- or right-handed photographers.

Lloyd says that ‘Whilst it’s not the first modular medium format camera system, [the 679 system] is the first system that allows the photographer to combine large format lenses with rollfilm backs from three different manufacturers in the same camera! At the same time, the lens board used for the 679 system are the same as those used on the SnapShot, allowing the photographer to seamlessly move lenses between both systems.’ Lloyd continues to say that the 679 system is lighter than ‘even the lightest large format systems’.

The 679 system and its components can be ordered here. The front plate costs £45, the lens board is £25 (pinhole is £30), the mid-body component is £40, and the film back is £40. A ground-glass back is also available for £30. Optional components range in price from £15 to £45. The most expensive add-on is the full grip with a wood finish.

Lloyd says, ‘I designed the 679 system for photographers who want to shoot a range of formats, without having to carry large heavy systems.’ It looks to be a well-designed product and it fills a unique niche.

Chroma Chrono is a programmable RGB camera flash for colorful long exposures

18 Sep

A new Kickstarter campaign seeks funding for Chroma Chrono, a programmable RGB camera flash that emits multiple colors during long exposures. Users can program the flash using a web interface accessible on any device with a web browser and WiFi; the system enables users to choose the flash colors and the on/off duration for each color.

Chroma Chrono features a high-intensity RGB LED, a WiFi-enabled microcontroller, and three AA batteries. Users can connect the flash to a standard hot shoe or trigger it remotely via a Prontor-Compur adapter. The camera flash currently exists as a final production prototype with anticipated manufacturing if the Kickstarter is successful.

Backers are offered an early bird Chroma Chrono flash for pledges of at least £120 / $ 164.

The Chroma is a lightweight, affordable, easy-to-use 5×4 field camera

22 Feb

A UK photographer and custom-built camera maker has launched a Kickstarter campaign to help fund a new 5×4-inch field camera that he intends to be lightweight, easy-to-use, unique, affordable and upgradable… as well as a bit funky. To that end, the Chroma will be made from brightly colored sheets of acrylic, laser-cut for accuracy.

Steve Lloyd has spent fifteen years creating custom cameras as one-offs, but decided to make a production 5×4 camera using modern materials and technologies.

The 3mm and 5mm acrylic sheets he uses allow cameras to be made in a range of colors—including Red, Pink, Blue, White, Green, Matte Black, Glossy Black, Purple and Yellow—while the lightweight nature of the material means the Chroma will weigh much less than a traditional wooden model. Even with the ground glass screen, the camera weighs just 1592g.

Here’s a quick intro to the colorful Chroma camera:

Lloyd has designed Chroma to provide a good range of movements in both the front and rear standards, with 40mm of rise and fall when both standards are in operation, and 30mm of shift in either direction at the front. Both standards allow 45° of tilt forwards and backwards, and Lloyd claims swing is limited only by the coverage of the lens in use and the ability of the bellows to flex.

The camera uses a clever back that is fixed with magnets built into the body, so it can be lifted off and rotated in seconds. The back is designed for standard 5×4 double dark slides, and Lloyd says he is working on designs for roll film and Graflok backs, as well as one for wet plate holders.

When fully extended the Chroma can stretch its bellows to 300mm, and it can be used with focal lengths from 65mm to 280mm. In the extended pose the camera measures 180x330x235mm, but it folds away to just 210x180x117mm.

The camera comes with a ground glass screen and a pin-hole lens to get new 5×4 photographers started. Users can choose Copal 0, 1 or 3 sized holes in a Linhof/Wista-style lens board, and those with existing Linhof/Wista boards will be able to fit them.

The Chroma starts at £250 (approx $ 350) for Kickstarter backers, and Lloyd says he expects to deliver between June and November 2018 according to the pledge you choose. Of course, no crowdfunding campaign is a guarantee, but given he’s already raised over $ 40K on a $ 13K goal, Lloyd is well on his way to a successful delivery.
