During the Second World War, the British firm Aeronautical
and General Instruments, or AGI, of Croydon had produced for the Air Force
and the Navy reconnaissance cameras based on the German Reflex Korelle
(Shriver, p 86). After the war, reportedly in 1946, they produced
a version of this for the general public: the Agiflex. This turned
out to be cosmetically and even mechanically very similar to the Reflex-Korelle,
but much heavier and much less reliable.
Features
This produced 6×6 (2¼" square) SLR, 12 exposures
with 120 film. Like the Reflex-Korelle, the Agiflex had a left-hand
film-advance lever and a rotating shutter speed dial providing speeds of
1/25 1/50 1/100 1/200 1/500 and B. The mirror was raised by finger
pressure and dropped back down when the finger was taken off the lever
(thus achieving an “instant-return mirror”!). It had a folding waist-level
finder, the sides of which were made of metal. There was a waist-level
finder with magnifier and a “sports finder” (direct vision finder).
The standard lens was an f/3.5 80mm “Agilux” stopping down to f/32 in a
small three-pronged bayonet mount. Flash synchronisation was provided
by two contact pins. |
“Amateur Photographer” reviewed the camera on 26th November
1947 and described it as “a high-grade single-lens reflex, of all-British
manufacture” (p 821). However, their test of the shutter speed showed
results that were anything but “high-grade”:

No wonder they wrote, “we should have preferred to see
the dial marked 1/250, 1/100, 1/50, 1/30, 1/20” (p 822). Worse, “at
the top speed the exposure given varies from 1/213 at the right-hand edge
of the picture to 1/313 at the left-hand edge, the value at the centre
being as given in the above table”. However, they generously did
not consider this to be a serious fault, stating “especially as it can
be put right by a trifle of shading when printing”. !!
They reported the price as being £42 10s 0d plus
£13 16s 6d purchase tax, making a total of £56 6s 3d (approximately
£56.31 in decimal currency). The “ever-ready case” was an additional
£2 5s 6d plus £1 17s tax, according to the same article.
At a time when a good steady wage in England was about £7 per week,
these were considerable sums of money. (The 1970 SLR Yearbook gives
the same price but slightly different calculations of the Purchase Tax.
It is probably fair to assume that the writer of the 1947 article was more
aware of the tax rates applying at that time.) |

At the time it was not possible to import foreign cameras
into England, except in extremely restricted circumstances and only with
a special government permit. Thus, in spite of the shortcomings of
the Agiflex and its high price, it was successful within the UK. |
