Olympus C-8080WZ with WCON-08D
Hans-Joachim Weber (2005-09-23)
The thing many people miss most when going the digital way is the availability of a "real" wide angle focal length. The
C8080WZ provides a range down to 28mm (in 35mm equivalent) which is not
comparable to a real wide angle. Lets tell it this way:
I really missed my MD W.Rokkor 24mm 1:2.8 lens and its focal length on my
I heard rumors, that the Olympus WCON-08D is a astonishing good
piece of glass and so I decided to give it a try. The Olympus C8080WZ with WCON-08D
reduces the focal length by a factor of 0.8 which in case of the C8080WZ results
to 0.8*7.1mm = 5.68mm focal length, comparable to a 22.4mm lens in 35mm equivalent.
And here mounted on my C8080WZ

havy piece of glass
and in top view...

Now let us look at my first pictures taken with this havy piece of glass.
This picture shows the impressing depth of field available with such a focal
The shot of the whole picture was downsized from the Olympus 8MPixel resolution
3264x2448 to 900x675.

Lets look together at my second picture taken with the WCON-08D.

This picture again demonstrates the very good contrast and
sharpness of this converter-lens combination.
Olympus offers the WCON-08D, a havy
piece of glass, to extend the focal range of the C8080WZ down to 22.4mm (35mm
equivalent) on the wide angle side.
Optically the WCON-08D in conjunction with the
C8080WZ in my Tests produces very good pictures in the aperture range from f2.8-4. The best
center sharpness is achieved from f2.8-f4, wheras corner sharpness increases to its
best at f4. Even wide open f2.4 the results are really acceptable.
Vignetting is very low and nearly
unvisible even at wide open aperture f2.4 a really astonishing result!
The handling of the large lens with the CLA-8 is not to be called optimal
IMHO. Especially the fine thread to mount the CLA-8
to the C8080WZ is sensitive and you have to remove the existing ring first
The only optical disadvantage of the
conversion lens I found till now is barrel distortion that becomes clear visible in
architecture and other critical applications, as usual with most wide angle zoom
lenses. For such applications its possible
to simply remove this distortion in post processing with photoshop or other
tools. Soon I plan to provide the necessary correction parameters for this combination here
in conjunction with additional picture examples.
So keep on watching this site!
