Horizon 202
I've recently purchased a Horizon 202, a Russian 35mm
panoramic swing-lens camera with a 28mm lens. This gives a 120
degree field of view with an image size of 58x24mm, a ratio of
2.4 to 1. I've had the first two test films back and here are
the results. All the shots on the first roll were blurred on
the right hand side due to the film not being taut inside the
camera (or perhaps due being loaded incorrectly). All shots
were taken on Velvia (using a tripod unless otherwise
specified), scanned with an Epson Perfection 2450 Photo scanner
(another recent purchase) and post processed with
Photoshop.
Overall I'm impressed with the sharpness of the lens. Only
the centre of the lens is used so the usual problems of
softness and vignetting at the edges of wide angle lenses is
avoided.
However, the very top of the photos exhibited vignetting and
odd marks (which I've rubber stamped out) but that can easily
be cropped off, and in most photos that would be a good idea
anyway since excess sky is rarely desirable unless the clouds
are particularly good. Cropping exactly 1/5th off the top gives
a very convenient 3:1 ratio which looks psychologically more
panoramic and stops the horizon being dead centre, so it's
probably a good thing to do that, being the next best thing to
a shift lens.
Oddly enough there seems to be no vignetting at the bottom
of the photos. Also I've noticed that the horizon is not dead
centre in the shots, but slightly lower, indicating that more
of the top of the lens is used than the bottom, hence the more
apparent vignetting. It's only a very small discrepancy
though.
A small number of photos have suffered from vertical
banding, which indicates that the rotation speed is not
constant, but it's only happened on three slow rotation shots
and all the others have been fine, so I don't know why this has
happened on these few occasions. More testing with slow
rotation is required. In practice I doubt I'll be using the
slow rotation very often anyway, so it shouldn't be much of a
problem.
Hand holding the camera seems to be quite practical,
although a tripod is desirable in order to get the composition
and the levelling perfect. It can be levelled hand held but
care is needed not to tilt the camera when pressing the shutter
release. One or two shots were a little soft at 1/60th so I
wouldn't want to make a habit of using that speed hand held, a
slightly faster film speed of 100 ASA would be better (Provia
F). The ideal compromise for fast moving work is a monopod,
which gives much better stability than hand holding, and makes
it easier to keep your fingers out of the way of the
lens.
