Canon AT-1 + FD 50 mm 1:1.8 Analogue camera

The Canon AT-1 is a 35 mm single-lens reflex (SLR) camera released by Canon in late 1976.

Created as an alternative and more economical version of the famous Canon AE-1, the AT-1 was produced exclusively for export and is aimed at photographers who value full manual exposure control.

Technical Main Features
Exposure Mode: Exclusively manual. It does not have the automatic or shutter-priority modes that exist on the AE-1.
Lens Mount: Uses the popular Canon FD mount, and is also compatible with the older FL-series lenses (through stopped-down metering).
Shutter: Electronic focal-plane cloth shutter. Offers speeds from 2 seconds to 1/1000 of a second, plus the Bulb (B) setting for long exposures.
Internal Metering: TTL system with center-weighted average metering. The viewfinder features a classic dual-needle (match-needle) exposure indication system.
Power: Requires a 6 V battery (model 4LR44 not included). Without a battery, the electronic shutter will not fire and the camera is inoperable.

Design and Ergonomics
Body Construction: Uses exactly the same lightweight, compact chassis as the Canon AE-1, sharing the same dimensions and almost all accessories, such as the Winder A film advance and Speedlite flashes.
Easy Focusing: The viewfinder includes a focusing screen with a central split-image prism and a microprism ring.
Simple Top Panel: Features a film advance lever, an integrated shutter speed selector with ISO (ASA 25 to 3200) sensitivity adjustment, and a battery check button next to the rewind knob.

Advantages and Differentials
Affordable Price: By omitting complex electronic automation circuits, it is often cheaper on the used market than the AE-1 and, consequently, more durable.
Photography Education: It is an excellent learning tool, as it forces the user to understand the direct relationship between aperture and shutter speed.
Lens Ecosystem: The FD mount provides access to one of the widest, sharpest, and most affordable collections of vintage optics in the world of analog photography.

Supplied with the Canon FD 50 mm 1:1.8 lens, one of the most iconic and popular classic lenses in the history of photography. Originally launched in the 1970s, it served as the standard kit lens for legendary cameras such as the Canon AE-1, AT-1, and F-1.

Today, it is highly sought after by filmmakers and digital photographers for adaptation to modern mirrorless cameras (such as Sony, Fujifilm, and Canon’s digital series) due to its distinctive look and excellent value for money.

Main Optical and Mechanical Characteristics
Focal Length: 50 mm – considered the “normal” lens for full-frame 35 mm format. It offers a perspective very similar to the human eye, making it ideal for street photography, portraits, and everyday use.
Maximum Aperture: f/1.8 – a fast lens, excellent for low-light photography and isolating the subject with a soft, aesthetically pleasing background (bokeh).
Totally Manual Construction: Focusing and the aperture ring are fully mechanical. The focus ring is known for being exceptionally smooth and precise, ideal for videography.
Optical Formula: Composed of 6 elements in 4 groups.
Evolution and Versions (FD vs. New FD)
There are two major aesthetic and mechanical variants of this lens on the vintage market:
Canon FD (Original Version / “Breech-lock”): Features a silver metal ring at the base to mount the lens to the camera. Typically uses 55 mm filters, has 6 aperture blades, and a heavier internal build due to more metal (weighing about 255 g).
And this Canon nFD (New FD): Released from 1979, removed the silver ring in favor of a completely black rotating-mount system (bayonet-style). It is lighter (170 g), uses 52 mm filters, closes down to f/22, and reduces the number of aperture blades to 5.

Visual Performance and Vintage Character
Sharpness: When wide open at f/1.8, the image shows slightly lower contrast and a softer edge appearance (producing a dreamy, highly praised vintage look). However, stopping down to f/4 or f/5.6 yields incredibly sharp and crystal-clear results, rivaling modern optics.
Colors and Tones: Canon FD lenses tend to render colors with a slightly cooler/blue tone in highlights and shadows, which at the time balanced the warm saturation of film.
Light Effects (Flare): Because they do not feature the most advanced digital coatings of contemporary lenses, they produce prominent circular and aesthetic flares when exposed to direct sun or strong lights.
An ideal set for anyone starting or returning to analog photography. The camera has been tested for mechanical reliability. Requires a battery to operate. Not tested with film.
