For vintage camera users, there is something distinctive about bringing an image into perfect focus manually. It is something that also gives the photographer a lot of control over the final shot. Lenses play an enormous role in the final form a photographic image takes. The classic Canon FD 200mm f/2.8 lens is enough to make any aficionado proud. Its telephoto capabilities let you create the image you want with full control of how you set the scene.Canon FD 200mm lenses are designed to be used with 35mm SLR film cameras. They have FD mounts, which lets them be used with Canon cameras that can accept that style of mount. These high-performance telephoto lenses are surprisingly compact and are easy to take along in your gear bag with your other equipment. That keeps them handy for the moment when they are the perfect tool for the job at hand. The lenses are about 5.28 inches long and have a diameter of 3.2 inches. They weigh about 28.22 ounces. If you need or want to use a colored or polarizing filter on these lenses, you can use filters that are 72mm in diameter.This prime telephoto lens has a fixed focal length of 200mm and has manual focus. It gives you a diagonal angle of view of 12 degrees that brings distant subjects right up to your eye. The lens will let you take shots with your camera of subjects as close as 1.8 meters, and being a telephoto type, it shines at the macro level of focus. The optical components in these Canon FD 200mm lenses consist of five elements in five groups. The elements are coated with Canon’s Supra Spectra Coating. This multi-layer SSC greatly reduces the occurrence of flare, ghosting, and reflections. It allows up to 99.9% of the spectral range from ultraviolet through near-infrared light to be transmitted through the lens to the sensor. The SSC coating helps you get great color balance and clear, sharp photographs with high image quality.Eight diaphragm blades control the aperture of the Canon FD 200mm telephoto lens. You can choose settings from a minimum of f/32 to a maximum of f/2.8. The option of using the wide-open aperture setting offers two advantages. First, it ensures that you can still get enough light to take your photo, even in poor lighting conditions. This lets you extend your day further toward the evening when you are still trying to get that perfect shot. It also maximizes your results in any situation where you are limited to using available light, including indoor events like theatrical productions. The second advantage is that the f/2.8 setting will let you capture fast action. This may be a sporting event, a photo of pets or wildlife on the move, or any other setting where your subject is not standing around waiting for you to compose your shot. With a lens like this, photo quality is often enhanced when you mount your camera to a compatible tripod.
