Ricoh GR film cameras

Ricoh GR film cameras is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ricoh GR film cameras rather than just read about it. In short: The Ricoh GR was a series of point-and-shoot, or compact, 35 mm film cameras made by Ricoh and introduced between 1996 and 2001. Specific camera models include the GR1, GR10, GR1s, GR1v, and GR21.

Key takeaways

  • Ricoh GR film cameras belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ricoh GR film cameras to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ricoh GR film cameras from memory before moving on to harder problems.

Reference excerpt

The Ricoh GR was a series of point-and-shoot, or compact, 35 mm film cameras made by Ricoh and introduced between 1996 and 2001. Specific camera models include the GR1, GR10, GR1s, GR1v, and GR21. The GR name was later used for Ricoh's GR series of digital cameras, which began production in 2005. The cameras had a very high quality 1:2.8 28 mm lens. Exposure control could be program automatic or aperture priority semi-automatic. They had a built-in flash and date imprinting versions were also available.

Overview

Because the diameter of a 135 film cartridge is 25 mm (0.98 in), most cameras were limited to a minimum thickness of 30 mm (1.2 in). Ricoh released the R1 in 1994, claiming it to be the world's thinnest camera; the camera has a distinctive grip section for the photographer's right hand which accommodates the film cartridge, but the remainder of the body is thinned down to improve portability. The R1 has a 30 mm f/3.5 lens with four elements in four groups and a panorama crop function; the body is made of aluminum, with a plastic rear door.

Although the R1 was commercially successful, professional photographers requested a camera with more manual controls, and Ricoh responded with the GR1. Compared to the R1, the GR1 uses a similar viewfinder but is fitted with a magnesium alloy body and a 28 mm f/2.8 lens which Ricoh claimed to perform better than equivalent lenses for single lens reflex cameras. The GR1 first was released in late 1996 and received the 1997 TIPA award for best 35 mm Compact Camera. As an operational quirk, the GR1 shoots backwards: when the cartridge is loaded initially, the camera winds the film all the way out, which takes approximately 30 seconds; as exposures are taken, the film is wound back into the cartridge. With its lightweight body, the GR1 had a weight and volume smaller than many 28 mm lenses for SLRs. British conflict photographer Philip Jones Griffiths owned and used a GR1.

Ricoh released a limited production run of the 28 mm GR lens in 1997, limited to 3000 copies, as a manually-focused lens with a M39 lens mount; the GR lens is nearly symmetric, featuring a concave front surface and seven-element, four-group construction. In 1998, a simplified version (GR10) and update (GR1s) were added to the line. Both shared the same 28 mm lens as GR1. The GR10 was fitted with an aluminum body and the aperture-priority autoexposure mode was removed. The GR1s had improved lens coatings for better flare resistance and other minor feature updates. Ricoh also released a 21 mm GR lens in 1999 as another limited production optic (1700 in total) with M39 mount; this was a nine-element, six-group lens which also had a nearly-symmetric design, and was almost as compact as the 28 mm lens.

The final two models came out in 2001: the GR21, with the wide 21 mm lens, and the GR1v, another incremental improvement on the GR1s. The GR21 won the 2001 TIPA Award for Best 35MM Prestige Camera. The GR1v adds fixed-focus distance settings (branded SNAP focus) and manual ISO selection. Japanese street photographer Daido Moriyama is known to have used the GR1v. The film GR cameras were discontinued after the introduction of the Ricoh GR Digital in 2005; over time, the most common faults that have developed have affected the status LCD on the top deck, the motor, and the light seals, particularly around the film information window on the rear door. In 2014, Ricoh discontinued service for the film GR cameras. The GR21 was made in limited numbers and tends to be more expensive than the others.

Worked examples

Example 1 — a first encounter with Ricoh GR film cameras

Start with the simplest possible case. Write down what Ricoh GR film cameras claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ricoh GR film cameras before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ricoh GR film cameras ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ricoh GR film cameras

In research
Ricoh GR film cameras appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ricoh GR film cameras in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ricoh GR film cameras is common in secondary-school and first-year university syllabi. It links to neighbouring topics Photography equipment, Ricoh cameras, so understanding it makes those chapters shorter.
In everyday life
Look for Ricoh GR film cameras outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
