General Sigma Information

Sigma Corporation (株式会社シグマ, Kabushiki-gaisha Shiguma) is a Japanese company, manufacturing cameras, lenses, flashes and other photographic accessories. All Sigma products are produced in the company's own Aizu factory in Bandai, Fukushima, Japan. Although Sigma produces several camera models, the company is best known for producing high-quality lenses and other accessories that are compatible with the cameras produced by other companies.[3]

The company was founded in 1961 by Michihiro Yamaki, who was Sigma's CEO until his death at age 78 in 2012.[4]

Sigma products work with cameras from Canon, Nikon, Pentax, Sony, Olympus and Panasonic, as well as their own cameras.

Sigma has also made lenses under the Quantaray name, which have been sold exclusively by Ritz Camera. Similarly, Sigma lenses were sold exclusively by the former Wolf Camera, but following the merger of Wolf and Ritz, both brands can be purchased.

Sigma's digital SLRs, the SD9, SD10, SD14 and SD15, plus the latest SD1 are unusual in their use of the Foveon X3 image sensor. The company's mirrorless cameras, the Sigma SD Quattro and SD Quattro H, use the Foveon Quattro sensor, an updated version of the Foveon X3. All use the SA lens mount. The Sigma DP series of high-end compact P&S cameras also use the Foveon Quattro sensor, which gives them a much larger sensor than other cameras of this type.

In September 2018 Sigma became one of the founding members of the L-Mount Alliance; it announced that it will cease to develop SA-mount cameras and instead use Leica's L-Mount. A new full-frame mirrorless camera, Sigma FP, was launched in 2019 along with a range of L-Mount lenses and adapters.[5]

Sigma is the world's largest independent lens manufacturer and is a family-owned business.

Looking after your camera

Use a Camera Bag

A camera bag does more than just protect the camera against scratches and dust: It keeps it safe from rain because many are waterproof on the outside.

Be Very Careful Around the LCD Screen and Camera Lens

Use only special equipment to clean your camera’s LCD screen and camera lens. Buy a special cleaning kit that includes liquid solutions, microfiber cloths and brushes that have been specially designed to clean your camera lens.

Never Leave Your Batteries in Your Camera for Too Long
Many camera batteries are now alkaline or lithium formats. If you keep your camera with the batteries inside of it in a moist area, then the batteries can get corrosive. So if you’re thinking about just putting your camera on the shelf for several months, do yourself a favor and remove them.

Turn Your Camera Off Prior to Doing Anything

Before you do anything to your camera, always keep in mind that it should be turned off first. No matter what it is—swapping lenses, changing memory cards or disconnecting or attaching cables—your camera should be turned off.

Cold and Wet Weather Can Wreak Havoc on Your Camera Body
Take your camera out only in a waterproof bag. If the weather’s unusually cold, just wrap your camera in a plastic bag that has silica desiccant packets for the reduction of moisture. It’s also a smart idea to have a soft towel with you to wipe off any moisture, just in case it should get on your camera.

Good Memory Card Care Is Good Camera Care

Only transport your memory cards inside of a protective caseMake sure the memory cards stay dust-free at all times. When removing memory cards, make sure you do so indoors or in non-dusty situations.
Make sure that you keep memory cards only in cool places. Never keep them in places where they may heat up, like dashboards or glove compartments.
Never place your memory cards close to magnetic sources. Examples of magnetic sources are things such as audio speakers, TV monitors and actual magnets.

Use a Filter to Protect Your Camera Lens

The lens of your camera is naturally fragile. As such, it’s susceptible to scratches, cracks, dents…you name it. A UV filter will not only will you give your lens a fighting chance, but you’ll also enhance the quality of your pictures.

Condensation Can Be Controlled

Condensation normally happens when you move your camera between different temperatures.
Allow your camera a chance to naturally get used to the hotter environment. Don’t place it inside a closed plastic bag when transporting it between different temperatures! Just let the camera sit in the humid temperature for a while, until condensation disappears.
If this still doesn’t get rid of all of it, you can utilize a soft cloth to wipe away any remaining moisture and marks left behind from the condensation.
