General Wray London Information

W. Wray founded his optical company in 1850 initially making microscope lenses. By at least the 1880s it was making lenses for cameras. The company had a reputation for producing excellent quality lenses and durable quality cameras including models such as the Wrayflex. Many Wray lenses remain in use, especially in photographic enlargers.

Wray also made aerial reconnaissance lenses. Their 36" f/6.3 is particularly good but has some residual spherical aberration at full aperture. They also made a highly distortion-free 36" f/4 for mapping. This can only be used with an orange filter and orthochromatic film to avoid the residual secondary spectrum (chromatic aberration).

Other products included the 12" Wide Angle Lustrar Code A 30010, Focusing Magnifiers, 4" F.10 APO Lustrar Code A 10010, and Wray Process Prisms.

Arthur Smith was the managing director and owner of the company, which had been created by his father, who left the Ross Optical Company to start it, initially as a small unit in Peckham.

Both World Wars caused the company to grow in size, due to the manufacture of service instruments such as binoculars.

Probably the most sophisticated lens produced by Wray was a 135 mm f/4.5 which has the unusual feature of a triple correction for astigmatism. It was designed by Charles Wynne, who was Wray's head optical designer at the time, having joined the company in 1943. In later years he went on to become a professor at Imperial College London, Optical department.

Wray had a specific development shop for unusual products, which was substantially replicated by Wynne at Imperial College.

Subsequent to this, David Day was appointed the technical director of Wray, heading a specialist optical design team. During this period, Wray developed special lenses for CERN and for microchip replication, with advanced features which probably accelerated the early development of microelectronics.[citation needed] Among many other projects, he developed an anamorphic projection system for cinemas, based on Brewster prisms.

Wray was closed in 1971 still in profit, its assets were worth more than the company

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.
