Titanium as Camera Housing Material

Titanium has superior performance, not only light, high strength, corrosion resistance, and excellent biocompatibility, non-toxic, harmless, non-allergic to the human body, and its appearance after anodic oxidation treatment, the composition of the oxide film has an antibacterial effect. Titanium is used in a very wide range of household goods, such as used as shell materials, lightweight materials, handicrafts and decorative materials.
Camera industry with titanium, first from the shutter screen began. Japan Optical Industry Corporation (Nikko) in 1959 in the Nikon (Nikon) SP and Nikon (Nikon) F on the use of pure titanium shutter curtain. At that time, rubber curtains or composites of rubber curtains and cloth and stainless steel foil shutter curtains were used for 35mm curtain shutter cameras. The pure titanium foil shutter curtain for the Nikon F was processed into a curtain that was 50um thick by rolling a thin sheet of JIS2-grade KS50 titanium to 25um, embossing the center in order to maintain strength and prevent scratches, and processing the surface to black. The sound of using this kind of shutter curtain is particularly small, and even if it is used in the theater, it can be used very well. Later other brands of cameras, such as Canon (CanonF1-1971), Minolta (Minolta X-1-1973), Olympus (OLYMPUS PEN-1993 and F3-2000), Kyodo (RTS2-1982) have also adopted the pure titanium foil shutter curtains.
After 23 years to 1982, in the "Nikon" NikonFM2, with titanium honeycomb structure of the longitudinal shutter to achieve ultra-high-speed l / 4000s fast shutter, than the previous camera speed to double the speed of the screen, greatly reducing the weight of the shutter curtain and improve the strength of the fast resistance, and so the "Nikon" FM2 in the longitudinal shutter, the use of titanium honeycomb, titanium shutter was later replaced by an aluminum shutter, aluminum shutter speed of 1/8000s.
As early as 1978 specifically for the University of Japan Arctic Expedition manufactured by Nikon P2 camera, the camera casing of the upper and lower cover, front and rear cover using titanium stamping, carried by the explorer Uemura Naoki to the Arctic Circle -40 ℃ ~ 50 ℃ under the use of cold weather, the results are good. Because the housing is resistant to low temperatures, vibration and shock, and is strong and durable, it was favored by the press, and at the end of 1990, the first all-titanium-housed pocket-sized camera was manufactured. In addition, Nikon (NikonFM2/T, F2Ti, F3T, F3P, 35Ti, 28Ti), Minolta (Minolta TC-1), Fujifilm (APS), Kyodo (CoNTaxT2, G1, G2) also use titanium housing.

Also the Nikon 5X15T double-simple microscope uses a full titanium housing. There are also in the sea photography Alifex-16mm camera shell on the use of titanium, but also achieved better results, titanium shell camera instead of aluminum shell, stainless steel shell camera, a good solution in the deep sea corrosion resistance, pressure resistance.
In early December 2008, Germany's Leica released a titanium limited edition D-Lux4, Lux5 series of digital cameras.D-LUX4 appearance of the card machine styling design, titanium alloy appearance so that the machine appears to be full of sense of light, the body size of the three dimensions of the 27.1mm × 108.7mm × 59.5mm, weighing 228g, the whole machine has a very good sense of texture. Priced at $1,400, which translates to about 9,700 yuan. Leica M9's titanium limited edition camera, handcrafted by Volkswagen Group chief designer Walter DeSchwa, has a titanium body with Summilux-M's 35mm f/1.4 titanium lens. In terms of configuration, the titanium version of the M9 and the ordinary version of the M9, using 35.8mm × 23.9mm frame 18 megapixel CCD sensor, Leica titanium version of the M9 is limited to 500 sets of the world, highly collectible. M9 titanium version of the camera is known as the "camera of the fighter", the offer of more than 200,000 yuan.
