Chamonix 4x5

A small Chinese workshop started building these in 2006 because anyone who wanted a wooden 4x5 field camera had two bad options: pay collector money for a vintage Deardorff that needed restoration, or buy a metal Wista and live with the weight. Chamonix split the difference. Hardwood, metal and titanium hardware, and a folding bed that collapses thin enough to disappear into a pack. The brand built its reputation slowly on the large-format forums, and by the time landscape shooters were asking what 4x5 to actually carry up a mountain, Chamonix had become the default answer.

Using it is the slow ritual the format demands. You open the bed, rack out the front standard, drape a dark cloth over your head, and compose on a sheet of ground glass that shows everything upside down and reversed. Focus is by moving the standards on a geared rack until the loupe shows the scene snap sharp. There is no rangefinder, no split prism, no autofocus, nothing electronic anywhere on the body. The movements are the point: rise, fall, shift, tilt, and swing on both standards, so you can straighten a building or run the plane of focus across a foreground rock and a distant ridge in one frame.

There is no shutter in the body at all. Every lens you mount carries its own leaf shutter in a Copal or similar barrel, and that is what times the exposure. You cock it, you fire it, you reset it by hand for the next sheet. The body's only job is to hold the lens and the film flat and parallel, and to bend that relationship when you want it bent. Film loads in sheet holders, one or two sheets per holder, dark slide pulled only after the holder is seated against the back.

Metering becomes its own task, because the body offers none. A view camera is the textbook case for the Zone Light Meter app: take an incident or spot reading to set your base exposure, then let it compute the bellows-extension factor when you rack the lens way out for a close subject, since that extension can cost you a stop or two that nothing on the camera will warn you about. Place your shadows, read your highlights, and you have the full Zone System in your hand.

The honest weakness belongs to the whole format, not the brand. It is slow, it is finicky in wind because that long bed and tall standard catch every gust, and a complete kit with holders and a few lenses gets heavy fast despite the clever materials. Sheet film is expensive and there is no second chance once the slide is pulled. People still choose Chamonix over a used Wista or Toyo because of the weight, the looks, and a build that has held up through years of trail abuse. If you want one camera to make twenty huge negatives a day, this is not it. If you want four perfect ones from a place you walked to, it is hard to beat.

How the app handles this body

  • Metering: Take an incident or spot reading in the app and place your shadows on a chosen zone, then dial that exposure in. On a body with no meter, or one whose cell has drifted with age, the app is the meter you trust.
  • Bellows extension: Rack the standards out for close focus and you lose light. Enter the bellows draw and the app folds the extension factor into the metered exposure.
