Cinema Products CP-16R Reflex (1972)

Fifteen pounds of magnesium that sat on a newsman's shoulder like a promise — and delivered.

Overview

The "R" in CP-16R tells you most of what matters: it's a reflex camera. Cinema Products took the non-reflex CP-16 — the single/double-system sound camera that had already made the company's name — and added a spinning mirror reflex viewing system, which is why the CP-16R exists as a separate animal at all. The company's own literature was blunt about the stakes, announcing "We're into reflex now" and calling the result "the most outstanding 16mm reflex news/documentary camera ever." That's advertising copy, and it reads like advertising copy. But the underlying claim — that this was a professional 16mm magnetic sound sync camera built for people who couldn't afford to miss a shot — holds up against what the machine actually was.

The story starts in 1972, according to the primary documentation, though some sources cite 1973 for the introduction. Either way, this is a camera of the early Seventies, made in the United States, finished in gray, and built around a magnesium body that weighs in at 15 lbs. That figure is worth sitting with. Fifteen pounds on a shoulder, all day, in a crowd, at a press conference, in the back of a moving van — that's the job this camera was designed to do. It's heavy by any modern standard, and owners describe it as resting "like a tool built to last, because it was." The magnesium construction is the reason it survives in the numbers it does; that material choice was not cosmetic.

What the CP-16R offered over its non-reflex sibling was, per the consensus among people who've used both, a reflex viewfinder and more lens options — the two things that make a camera usable rather than merely functional. The reflex design meant the operator saw through the taking lens, and the CP-mount opened the door to a wider range of glass. Cinema Products built the thing to be silent, and "sound-silent" was the phrase used at the time — a camera quiet enough to shoot sync sound without a blimp, which is the entire point of a newsfilm camera.

Key Features

Spinning Mirror Reflex Viewing

The heart of the CP-16R is its spinning mirror reflex system. A mirror shutter rotates in the light path, and when the camera stops, it parks automatically in the viewing position — so the operator isn't guessing where the mirror landed. Cinema Products' own documentation describes the mirror shutter as set at a 45° angle and stopping automatically in a viewing position, which sounds like a small convenience until you've spent a day with a camera that doesn't do it. The reflex path is what separates this camera from the CP-16, and it's the reason the "R" designation exists at all.

Fiber Optics Viewing Screen

Here's the detail that separates the CP-16R from a lot of reflex cameras of its era: the viewing screen is fiber optics, not ground glass. Cinema Products made a great deal of this, and the reasoning is sound. A conventional ground glass stops the image but throws away light doing it. The fiber optics screen has the same image-stopping properties without the same transmission loss, which means a brighter image and — critically — no dark, coarse, grainy center spot. Edge-to-edge critical focusing is possible across the entire field of view, with no ground spot in the middle and no guessing at depth of field. For TV-news work, where you're focusing fast in bad light, that's not a luxury. Cinema Products noted the camera was used by Wolper Productions on the "Lincoln" television specials at Paramount Studios, which is the kind of credit a manufacturer puts in the brochure when it wants documentary and studio shooters to pay attention.

CP-Mount and Lens Options

The CP-16R uses a miniaturized BNCR-type lens mount — the same breed of mount found on professional 35mm studio cameras, scaled down. It has a positive locking ring and a locating pin that maintains proper lens orientation, and the design protects lenses against torque-related damage; a twist of the locking ring secures even heavy zooms. The camera was commonly paired with Angenieux glass, and listings and documentation reference both a 10-150mm zoom in CP-mount and an Angenieux 12-120mm T2.2 zoom. The 1.33:1 ground glass and mattes were the standard framing setup. Buyers should note that the CP-mount's lens ecosystem is the practical limit on what a CP-16R can do today — the mount is the camera's greatest asset and its biggest constraint, depending on what glass you can find.

Frame Rates: Crystal Sync and Variable Speed

The CP-16R runs at 12, 16, 20, and 24 frames per second, crystal controlled, plus 28, 32, and 36 fps for slow-motion work. The 24 fps crystal-controlled setting is the sync-sound workhorse — that's the "24 FPS Sound Camera" designation you'll see on listings, and it's the mode the camera was built around. The variable speeds are a genuine bonus for documentary shooters who needed over- or under-cranking without a second body. Note that the frame-rate list comes from a single source (Visual Products), so treat the exact speed set as documented-but-not-triple-confirmed.

Single-System Magnetic Sound

The CP-16R records magnetic sound sync in single-system — a built-in magnetic sound head captures audio on the film itself as you shoot. This is the "magnetic-only" design, the same broad approach Auricon used, and it's the reason the camera was described as a "professional 16mm magnetic sound sync camera." Single-system sound saves the sync-clap-and-slate dance of double-system work, which is exactly what a newsroom needs. The tradeoff is baked into the format: magnetic-only means the sound lives on the film, and that constrains how the footage can be handled downstream.

Magnesium Body, Shoulder-Ready

Fifteen pounds, magnesium, gray. The body is built to ride on the shoulder, and the material choice — magnesium — is why so many of these cameras are still around and still running. It's not a light camera by any stretch, but it's a camera that was designed to be carried and used rather than coddled. The CP-16R's reputation as a newsroom workhorse rests on exactly this kind of unglamorous durability.

Historical Context

The CP-16R was built for 1970s newsrooms where silence, reliability, and precision came first. Cinema Products positioned it squarely at TV-newsfilm and documentary work, and the company's advertising leaned hard on the reflex conversion as the headline news. The camera quickly became one of the most popular 16mm spinning mirror reflex, sound-silent cameras on the market — a claim that comes from the manufacturer's own promotional material, so read it with the appropriate skepticism, but the design's popularity is corroborated by how many survive and how often they turn up for sale.

Within the Cinema Products line, the CP-16R sits above the non-reflex CP-16 and CP-16A; the consensus among users is that the R is the superior camera because of the reflex viewfinder and the wider lens options. The CP-16R also shares the "System CP-16" ecosystem — the Crystasound recording system, power supplies, and accessories were interchangeable between reflex and non-reflex models, which mattered to a newsroom that already owned CP-16 gear. Cinema Products also offered a "Crystaslate" modification for the CP-16R, an auto-slate edge marker with bloop tone and sync pulse output usable with Nagra 3 and 4 recorders, ordered at the time of purchase for $650. That's a small detail that tells you a lot about the workflow the camera was born into.

Collectibility & Value

The CP-16R occupies an odd place in the market: a newsroom workhorse now prized by film purists. It's not a rare camera — plenty were made and plenty survive — but the reflex version commands more interest than the non-reflex models, and converted Super 16 examples (Super 16mm/video tap modifications, "CP-16R Super16 Camera Package," "CP-16R Ultra16 Converted Camera") attract a different tier of buyer entirely. A used listing for a CP-16R with a Peter Lisand Ultra 1 Fluid Head and aluminum tripod was priced at $3,300; that's a current asking price, not an original sale price, and the fact sheet has no original manufacturer price on record.

Condition varies enormously, and the listings tell the story. Sellers report "new belts, runs great," but also "2 batteries (only one works) and 2 chargers," and one unit was listed with a "regular viewfinder — prisms needs re-silvered." The orientable viewfinder is described as rare, and a degraded prism is a real repair concern on any example. The best listings note that the "camera body & magazines have been SERVICED by a VETERAN FILM CAMERA TECHNICIAN and checked for proper operation" — that's the phrase to look for. Accessories commonly bundled include 2 400ft magazines and the Peter Lisand fluid head and aluminum tripod.

Buying advice, such as it is: the reflex viewfinder condition is the thing to check first, because re-silvering prisms is not a trivial fix, and battery health is the second — these cameras were built around power supplies that are now decades old. A serviced body with good glass and working batteries is the target; a "very good condition" cosmetic grade means little if the viewfinder is dim. The magnesium body survives; the optics and electronics are where the money goes.
