CANON T90
The Canon T90 is the last and most advanced manual focus 35mm single-lens reflex (SLR) camera Canon made before it switched fully to autofocus with the EOS system. Released in 1986, it is the end of the line for Canon's FD-mount SLRs, with sophisticated electronics, an ergonomic design and professional-grade performance.
Overview
Canon introduced the T90 in February 1986 as the flagship of its FD-mount SLR lineup. It succeeded the F-1 and New F-1 as the top manual focus camera. It was designed for professional photographers and advanced amateurs, with maximum automation and precision but full manual control still available. It was the last of Canon's manual focus SLRs. The EF-mount EOS system followed in 1987 with the EOS 650.
The T90 was not meant to compete directly with the coming autofocus models. It was a technological showcase and a bridge between mechanical and electronic camera design. It was aimed at photographers who wanted manual control but also wanted electronic automation, such as program exposure, multi-spot metering and motorized film handling. Its futuristic, ergonomic body was developed with industrial designer Luigi Colani, who used biomorphic curves and a user-centric layout to improve grip, button placement and usability.
The shutter is a vertically traveling, focal-plane type with electromagnetic control. It times exposures from 30 seconds to 1/4000 second, plus Bulb mode. An integrated motor drive advances film at 4.5 frames per second - on par with professional motors of the time - and optional battery packs support continuous shooting. The T90 also brought Canon's most advanced metering system to date: a six-segment silicon photodiode (SPD) sensor giving center-weighted, partial and multi-spot metering. That allowed highly accurate exposure readings even in challenging lighting.

Historical Context
The T90 arrived as manufacturers were shifting from mechanical to fully electronic camera systems. Canon had already invested heavily in electronic SLRs with the A-series (AE-1, AT-1, AV-1, etc.) and wanted a definitive manual focus model that showed the peak of what the FD-mount system could do. The T90 used lessons from the AE-1 Program and the New F-1, combining professional durability with consumer-friendly automation.
Its main competitors were the Nikon F3 (and later F4), Minolta X-700, Pentax Super Program and Olympus OM-4. The Nikon F3 stayed the choice of many photojournalists for its rugged mechanical reliability. The T90 offered better automation and a more modern interface. But its release coincided with the dawn of autofocus - Minolta launched the Maxxum 7000 in 1985, the first successful integrated autofocus SLR - so the T90 was somewhat obsolete before it reached full market potential. Canon's own EOS 650, introduced in 1987, used a completely new EF mount and full-time electronic lens communication. FD lenses were incompatible with it, which sped up the T90's decline.
Commercial success was limited, but the T90 was critically acclaimed for its innovation. It was a testbed for technologies later used in EOS cameras, including the LCD menu system, multi-zone metering and electronic exposure control algorithms.
Collectibility & Value
Today the Canon T90 is a sought-after collector's item, particularly among enthusiasts of vintage SLRs and industrial design. It is not as rare as some limited-production models, but its relatively short production run (1986-1991) and its status as Canon's last manual focus flagship add to the demand. In excellent working condition, the T90 typically sells for $200 - $400. Models with the Speed Booster grip or original packaging command higher prices.
Check that the electronics work. Aging capacitors and circuitry can cause meter inaccuracy or shutter timing errors. The T90 uses two 6V 4SR44 or PX28 batteries (or modern equivalents like A544) to power the meter and electronics, and they must be installed correctly to avoid damage. Common problems are sticky shutter curtains (from dried lubricants), worn film transport gears, and dim or dead LCD displays. Canon discontinued support for FD-mount cameras decades ago, so repair parts are scarce and expertise is limited to specialized vintage camera technicians.

Repair & Maintenance
The Canon T90 requires two 6V 4SR44 (or PX28/A544) batteries, which mainly power the metering system, LCD display and electronic shutter control. They go into the grip or the optional Speed Booster. Because most units are old, battery leakage is a common concern and can damage internal circuitry if not dealt with promptly. Regular maintenance means cleaning the mirror and focusing screen, checking shutter accuracy across all speeds, and making sure the film advance runs smoothly.
The electronic complexity makes repairs hard, and few technicians know the proprietary Canon FD-era circuit boards. Replacement parts such as shutter assemblies or metering modules are scarce. Only experienced technicians should lubricate the film transport and shutter mechanism, since improper servicing can cause long-term reliability problems. For long-term storage, remove the batteries, keep the camera in a dry place, and cycle the shutter periodically to prevent sticking.
