Photomicrography - yes, you can even take
pictures through a microscope with your Zenith!
At moderate magnifications no accessory is
needed other than a rigid tripod or copy-stand to
hold your camera, complete with lens, over the
eyepiece of the microscope. For more
professional results and and at higher
magnifications the camera body should be
attached direct to the microscope by means of a
42mm thread mount GA-3 Microscope Adaptor
(obtainable through your dealer or direct from
Zenith House).
Lens Hoods
help prevent stray light rays (from outside the picture area) from entering the lens and
causing flare due to reflections from internal camera and lens surfaces -they generally improve picture
contrast and are certainly essential if pictures are to be taken against any strong light source. Both
folding rubber and rigid metal types are available from your dealer and these vary in shade and size
according to lens focal length.
(NEVER use a hood intended for long focus lens
with a shorter focus lens.) Filters, usually made
of colored glass or gelatins, are used to create
special effects or improve rendering or contrast
with color or black and white films. The present
Hellos Filter range, as you will see from the
details below, gives very good general-purpose
coverage. All are fully-coated and come in
individual twist-lock cases. Since a filter absorbs
extra light, compensation is normally made by
increasing the aperture (f/stop) by the factor
engraved on the filter mount. With the Zenith
TTL, the CdS meter once again provides
automatic compensation.
