For example, the Helios Auto 1 35 has a focusing range of 1 .5m to infinity; whether the 2x or 3x
converter is used, the resultant combination still focuses from 1 .5m to infinity, giving you a telephoto
lens that allows you to get in really close.

When using lenses of 200mm focal length or longer there may be some slight "cutting off" effect
on the left hand side of the film image but this will probably be masked off by the slide mount or
in printing.
Close Up Photography comes easy with your Zenith. Many pictures (say of two or three flowers, book
or magazine illustrations) can be taken without any accessory at all --just turn the Focusing Ring
(11)
of
your standard lens to its minimum distance and move your camera towards the subject until the
viewfinder image is at its sharpest. . . you'll find you can fill the frame with an object around 6 1/2 x 1 0
in in area. For smaller subjects you need to get closer by using a
supplementary close-up lens
screwed
into the filter mount of your standard lens or
extension tubes
or
bellows unit
inserted between camera
and lens.
Supplementary lenses, are easiest to use since they do not require any exposure increase -- not that this
is a problem with the Zenith TTL, thanks to automatic meter compensation. A slight disadvantage is that
because they add another glass-to-air surface they do impair the fine resolving power of the camera lens
at the edge of the field unless the aperture is stopped well down.
