The Curtagon Story

Part 3


[C372-5A: The “mythical” Joseph Schneider Kreuznach 40mm f/4 Curtagon lens on an Exakta 66 Mk III]

How do the images captured with this 40mm lens compare with using a “standard” lens of 80mm focal length?

[C377-3: 80mm Xenotar 1/500 f/22]
[C377-1/2: 40mm Curtagon 1/500 f/22]

No prizes for composition with either of these pictures, but the idea was to show the field of view of the 40mm Curtagon, compared with the “standard” 80mm Xenotar lens.  Both images shot on an Exakta 66 Mk III body, using the Exakta TTL metering prism.  Vignetting no longer seems to be a factor, and definition is sharp to the edges.

It has not been possible to return to Hitchin town square to take pictures with this lens, but here are some other shots taken with it.

[C377-14/15] 40mm Curtagon 1/250 f/11
In the original, by enlarging massively, the details on the plate 
half way up on the left are clearly visible.
The only limiting factor is the grain of the film (FUJI NPH 400)

[C377-12] 40mm Curtagon 1/250 f/22
Before printing this shot I cropped out most of the foreground
to improve the compositon, but here I have included the full frame
to show the definition into the corners

The results certainly seem to justify all the effort involved in the project to mount this lens on the Exakta 66 camera.  It is very sad that this lens did not become more widely available.

Here are a few more pictures taken with this lens:

P6 Fujicolor Pro 160S 40mm Curtagon 1/125 f/22 11/4/12 Görlitz and the Neiße river from Poland

 P6 Fuji Pro 400H 40mm Curtagon 1/250 f/22 14/4/12 View out of the window of our hotel room in Dresden
The picture on the left above shows in the sky a typical mildly wide-angle effect.  The image on the right above is pictorially not a great image, but it is a good test of the 40mm Curtagon.

P6 Fujicolor Pro 160S 40mm Curtagon 1/250 f/19 11/4/12 Der Untermarkt, Görlitz

P6 Fujicolor Pro 160S 40mm Curtagon 1/125 f/22 11/4/12 Sohrstr., Görlitz
For these two pictures minimal perspective correction has been applied (I did not have a shift lens with me on this trip!), and the images have been slightly cropped on each side to suit the composition.
