Canon A-1

In 1977 the Canon AE-1 marked the shift of cameras from manual models to electronic ones. It was an electronic SLR camera with a CPU which linked the electromagnetic release, self-timer, and electronic flash electronically. A year later in 1978, the Canon A-1 was introduced, the first camera in the world to have all exposure functions controlled by a microcomputer. It enabled aperture-prority and shutter-priority autoexposure.

"The A-1 has a cloth shutter, and it tends to stick at times or emit the dreaded Canon 'squeal'. Many used examples have broken or taped battery doors. These are the complaints often directed to this progressive masterpeace in camera manufacturing. Unlike the hardest competitor Nikon, Canon has changed the lens mounting and the current Canon EOS autofocus EF mount is not compatible with the FD-mount. Still it was definitely one of the most advanced contemporary cameras. Canon A-1 is the camera which the popularity of IC circuits for automations in camera design have very much to thank for. The camera is totally dependent on batteries. A feature which is more than a contingency today even on a toothbrush. In many aspects you get much more than you lose. The diversity and easiness of usage and the accuracy of functions got a new level with this beauty."

Canon A-1 was introduced in 1978 and despite of a quarter of a century this vintage camera still remains as the ultimate reference camera for many. Its styling, durability and reliability have been proven over these years and passed the enduring time test and emerged as a true classic.

Canon AV-1
Canon AV-1
is a focal plane shutter SLR camera with a TTL light metering. Production begun in the first half of 1979. I bought this Canon because I just wanted to have another item of Canon SLR brand. Why then AV-1 ? Because it was relatively cheap and had a good reputation within the cameras of it´s class. It proved very handy and easy to use. It also takes technically excellent pictures.All you need to do is turn the aperture ring on the lens to set an aperture, focus and press the shutter button. Focusing is manual. The camera does all the rest - provided the main control dial has been set to the "A" mark..It has center weighted average light metering with a back light compensation possibility. When shooting your subject under backlighting condition, you just push an extra switch to compensate the exposure. At least in Finland it was commonly bundled with Canon FD 35-70 F 1:4 zoom lens

Canon TC-5000

I hereby proclaim a competition to conceive of a new name to this exceedingly innovative high tech gadget. TC-50000 is absolutely too modest.

Something like,
Galactic XMTR Nano Supercharger Mark II
would be better.

(Edit: Aug 8, 2007) According to specialists the model name of this rare Canon camera could be Plasticam Sinonippon Bogusfocus PDQ or the more common WhatCopyright?100.

One thing is bothering me... Is the lens made of glass, because it is not mentioned anywhere??
