Canon Finders

 

A Description of Viewfinders for Canon Rangefinders 1950-1965

 


 

First Canon Accessory Viewfinder

 

In March 1950, Canon released its first wide-angle lens, the Serenar 35mm f3.5. This lens was delivered in a very nice leather case with the lens name stamped on the top. Inside, as well as the lens and lens cap, was a Canon 35mm accessory finder with rear adjusting parallax ring in a fitted pocket in the lid of the leather case.

Later Canon Finders

 

Since the introduction of the Canon IIB in 1949, all Canon cameras had viewfinders that displayed multiple focal lengths, besides the standard 50mm lens view. These varied from 50mm, 100mm, 135mm in the earlier models to 35mm and 50mm in later, and finally with multiple displays later. Some later model viewfinders had parallax correction and some had bright line outlines of the lens coverage. However, for most lenses, particularly telephoto and wide angle lenses, Canon recommended accessory viewfinders, nearly all of which included parallax correction.

 

Canon Universal Finder

 

There were two versions of the Canon Universal Finder. These covered a wide range of focal lengths. Both Universal Finders featured parallax correction.

 

Canon Universal Finder - 1

 

In about 1952, Canon introduced an accessory finder which could be inserted in the accessory shoe and adjusted for focal lengths from 35mm to 135mm. I call this the Canon Universal Finder - 1 (not an official name).

This finder also had an accessory attachment to extend the finder range to include 28mm. This extension, however, was easy to lose - I know from experience - and it is also hard to find on secondary markets.

In 1956, Canon introduced a second Universal Finder, which I call the Canon Universal Finder - 2. The Canon VT camera of 1956 and later cameras (listed below) had a number of innovative features, including provision for automatic parallax correction of accessory finders, via a pin in the accessory shoe.

The 1956 Canon Universal Finder - 2 had an automatic parallax correction linkage to a number of Canon models:

 

- the Canon VT, VTD

 

- the Canon L1, L2, L3

 

- the Canon VL, VL-2

 

- the Canon VI-L, VI-T

 

- the Canon P

 

Canon Finder Automatic Parallax Linkage

 

The Canon cameras listed above had a new feature in the accessory shoe. A pin in the center of the accessory shoe raised and lowered as the rangefinder focus was changed. This pin linked to a series of new V-type Canon accessory finders. The finders would rest on this pin in the accessory shoe and raise and lower, as the pin in the accessory shoe raised and lowered, allowing the finders to automatically automatically for parallax. This was an advanced feature unique to Canon.

Canon Fixed Finders

 

Described above are the advanced finders which automatically corrected for parallex via a pin in the accessory shoe. Canon finders for earlier cameras were fixed in the accessory shoe, and parallex correction was done manually by the photographer, turning a small distance dial on the back of the finder, or sometimes with a manual lever setting as can be seen in the photograph below.

the center finder has a distance adjustment lever at its base

the right finder has the pin in its base linking to the the automatic parallax correction described above.
