This article comes from Jiayou Online
As mobile photography has become more powerful, in the traditional digital camera market, in addition to some special-purpose digital cameras also have a place, general digital cameras have become a double history Covered by the torrent. The digital camera to be introduced in this article is a digital camera with a special purpose, so it can survive on the market. It is Ricoh’s G900 with the necessary waterproof, dustproof, impact resistance and corrosion resistance.
The Ricoh G900 is the successor to the G800. It is equipped with a back-illuminated CMOS with approximately 20 million effective pixels, allowing the camera to shoot brightly even at low light levels. Equipped with a 28-140mm lens that supports 5x optical zoom, a wide-angle adapter and a 37mm third-party filter to prevent lens condensation and scratches.
In terms of protection performance, compared with G800, the drop performance of G900 is increased to 2.1m, and the volume of the whole machine is reduced by about 26%, realizing the miniaturization of the fuselage. The waterproof performance has reached IPX8, and the dustproof level has reached IP6X after 2 hours of continuous use at a water depth of 20m. In addition to the second time, G900 has also strengthened drug resistance and has toughness that is indispensable in harsh scenes.
Ricoh G900 main parameter table:
Overall appearance design
In terms of body design, as mentioned before, Ricoh G900 has reduced the overall volume by about 26% compared with the previous generation G800, and the body measurements are 118.2 x 65.5 x 33.1 mm, when equipped with battery and memory card, the weight is only 246g.
Ricoh G900 machine Front of the body
The front of Ricoh G900 mainly has a handle, AF assist lamp/Selfie indicator, lens, LED ring light and flash. In terms of appearance design, G900 seems to incorporate the design language of the PENTAX WG series into the Ricoh G series, and the two design styles are very well integrated.

On the back of the fuselage, the G900 is equipped with a 3.0-inch large high-definition LCD display with approximately 1.04 million dots. The protective panel outside the display screen is coated with AR coating, which can effectively inhibit the reflection of external light, reduce projection, and can be clearly viewed outdoors in strong sunlight. In addition, users can adjust the brightness of the screen according to the lighting conditions of the environment. The density of the buttons in the right button area is higher, and there is a certain possibility of misoperation.

For waterproofing needs, the sides of G900 are also There are no openings and lids. Also for use needs, the G900 is equipped with two lanyards, which can be hung on the chest or vertically on the neck, so that the camera can be easily placed In the chest pocket.
Body design details
Ricoh G900 lens
Ricoh G900 is equipped with a 28-140mm lens that supports 5x optical zoom. It has a wider field of view than a 35mm lens and is suitable for indoor shooting. It can also take long-distance shooting. The adjustable LED ring light around the lens is obviously inherited from the PENTAX WG series. Users can select the led lights and adjust their brightness to get a clear lens display details, such as the model on the small parts or the wall, scratches on the floor, etc. It is also very useful when shooting in 1cm macro mode.
Ricoh G900 Micro Distance bracket
This macro bracket is mainly used in 1cm macro mode or digital microscope mode. After assembly, the distance between the lens and the subject will be fixed at 1cm.
Ricoh G900 interface
Due to the need for waterproof performance, Ricoh G900 has a waterproof compartment at the bottom of the fuselage, so the data interface, memory card slot, battery, etc. of the fuselage are concentrated here. In terms of interfaces, G900 has a USB3.0 Type-C interface and a D-type HDMI interface.
Ricoh G900 storage Card
G900 supports the use of SD/SDHC/SDXC memory cards, but it also has a built-in storage space of about 6.5GB, which can shoot about 856 images, so even if you forget to bring the SD card or SD card capacity You can continue shooting without worry when it is full.
Ricoh G900 battery
G900 uses a DB-110 1350mAh lithium battery as the power source. The battery life is about 340 cards, and the battery life is average.

As a special-purpose digital camera, Ricoh G900 officially relies on its special performance to gain a foothold in the digital camera market. Let’s take a look at what makes the G900 stand out.
Strong three defense performance
Ricoh G900 is waterproof, dust-proof, impact-resistant and corrosion-resistant. It adopts a highly air-tight body structure to achieve the IPX8 high water resistance standard for continuous use at a water depth of 20m for 2 hours, and the dustproof performance also reaches IP6X. Its body is small and lightweight, while the front end of the lens is equipped with a reinforced protective lens, and a protective layer is installed at an important position, which has the 2.1m drop impact resistance under the harsh field environment. At the same time, it also has a cold-resistant structure that can work normally at minus 10°C and a pressure-resistant structure of 100kgf. It is also an industrial digital camera that is corrosion-resistant to the disinfection of ethanol, sodium hypochlorite, chlorine dioxide water, etc., which are used as food additives.
Electronic blackboard function for fortifications
The function of the small blackboard for fortifications refers to the use of electronic photography to replace the traditional way of writing notes on the blackboard with chalk. The advantage of the small blackboard for fortifications is that there is no need for additional staff to operate the blackboard, and the entire process from preparation to shooting can be completed alone. Even if standing at a high place or inconvenient to stand, it is convenient to use the small blackboard function to shoot in a dark scene. . By entering information such as the name of the fortification, type of work, and location in the camera memo information, it can be added to the captured portrait later to make the management of the portrait and the creation of the account book more efficient.
Watermark shooting function
Ricoh G900 can Use an existing picture as a template. The template transparency can be selected from 20%, 40%, 60% and 80%, and photos with the same composition as the template can be compared side by side. This function can be used to compare before and after construction on a construction site.
When viewed from an angle When photographing logos, business cards and other rectangular objects, use the “tilt correction mode” to reduce the perspective effect. The camera will also record uncorrected photos. Users can choose to display guides to help correct deviations.
Camera lock function
Ricoh G900 can Protect the entire camera by setting a password. By encrypting the camera or internal memory, the image can be encrypted, and the password can also be unlocked by changing the camera settings. Users can gain access by scanning a barcode or entering a password on the on-screen keyboard. It can also encrypt the SD card.
In view of the needs of special purpose and industrial use, there will be a higher demand for the lens distortion used by Ricoh G900, let’s explore it through the test pictures Exactly

Ricoh G900 telephoto end distortion test chart
From the picture, there is no distortion at the wide-angle end and the telephoto end of the Ricoh G900. This shows that the optical quality of the lens on the Ricoh G900 It is very good, users can rest assured to use each focal length when shooting.
Ricoh G900 is equipped with a 1/2.3-inch back-illuminated CMOS with approximately 20 million effective pixels, and its native sensitivity ranges from ISO 160-25600. Let’s take a look at the actual sensitivity performance.
Ricoh G900 photosensitive Degree test table
It can be seen from the test picture that the Ricoh G900 can be regarded as a relatively clean picture within ISO 800, and the details are basically preserved. When it rises above ISO 1600, there will be a lot of noise and the picture is smeared. Also enhanced, the details began to be lost. In practical applications, the performance under IS0 1600 is also acceptable.

In the shrinking traditional digital camera market, waiting for products with little ability will disappear as a result. Ricoh G900 can survive because of its special purpose. Needless to say, the high-spec four-proof performance of waterproof, dustproof, impact, and corrosion resistance, the electronic small blackboard function, watermark shooting function, tilt correction and other functions are all highly targeted. It is these performances and functions that make Ricoh G900 still occupy a place in the market and become a very useful industrial digital camera.
