The Canon New F-1 replaced the F-1n (an upgraded F-1) as Canon's top-of-the-line 35mm single-lens reflex camera in 1981. Like the earlier models, the New F-1 takes FD-mount lenses. Although no date has ever been confirmed, it is thought that the last New F-1 was still being made in 1992. It was officially discontinued in 1994, and factory support ended in 2004. The New F-1 is a manual-exposure camera capable of TTL full-aperture metering and stopped-down metering with the included Eye-Level Finder FN. Aperture-priority AE is available by attaching the optional AE Finder FN. Also, shutter-priority mode is optionally available when using either AE Motor Drive FN or AE Power Winder FN. The New F-1 is an expandable system. It consists of interchangeable viewfinders, focusing screens, motor drives, and alternate backs, all of which are specific to the New F-1. All other Canon components, such as the FD lens series, close up accessories (bellows, extension tubes, etc.), and Canon A and T Speedlights (except the 300TL) are also compatible with the system. Interchangeable viewfinders The New F-1 system has 5 different viewfinders, which can be quickly and easily changed by depressing the two buttons on the rear of the finder, pulling it off the camera body, and pushing the new finder into place. Eye-Level Finder FN AE Finder FNThe Eye-Level and AE Finders are the basic eye-level prism finders, similar to most other SLR systems' prism finders. Both include a hot shoe for on-camera flash, or attachments to remotely trigger the shutter. Both also include an integral eyepiece shutter, which closes over the eyepiece to prevent light leakage during long exposures.When using the AE finder, setting the shutter speed dial to 'A' engages a small switch on the finder which puts the camera into aperture-priority auto exposure mode. The normal meter display to the right of the through-the-lens (TTL) image disappears from the viewfinder, and a different meter display appears below the TTL image, which indicates which shutter speed the AE system has chosen. Speed Finder FNThe Speed Finder uses two separate prisms separated by a swivel, to allow either eye-level or waist-level viewing, and the ability to switch quickly between the two. The optics are designed in such a way that the finder's image is visible up to 6 cm away from the eyepiece, enabling the photographer to use the finder even with glasses or goggles. The Speed Finder
