with most microscopes. Extreme right: The close-up attachment is
a simplified version of the combination of table stand and field

The Close-up Attachment
When working with the ultra-close R lenses the reflex screen will, of course, permit parallax-free focusing.
Nevertheless, for close-ups of live subjects the use of the Retina close-up attachment is recommended. It
consists of a camera platform which takes four alternative sets of legs which act as a distance gauge and show
the correct field area covered at the same time.
To use it, screw the R lens required to the camera lens and clamp the corresponding set of two legs into the
appropriately marked notches of the attachment. Then approach the subject until it is in the plane of the gauge
rods fixed into the front ends of the legs.
The Table Stand
The table stand has been developed for close-up subjects which allow or need longer exposure times as well as
for all types of close-ups where quick setting-up and absolute steadiness of the camera is important.
The stand consists of a U-shaped base with an adjustable column and a ball and socket head. The latest version
has, in addition, a baseplate to support the camera in its centre. The stand can be taken apart into its individual
components for easy transport and storage. It is specially useful for close-ups with the N close-up lenses.
Alternatively, the ultra close-up lens set R1:2, R1:3 and R1:4.5 can be used with the table stand in conjunction
with a frame holder and close-up field frames showing the correct distance and field with these R lenses. This
ultra-close-up attachment for the table stand is, however, no longer in production.
The Copying Stand
For quick and convenient copying of documents, important letters, valuable prints, book pages and the like from
about 6 x 8 in. to 8 x 12 in. in size a special copying stand has been designed.
The outfit consists of a camera holder which takes four extendible legs. The bottom ends of the legs are fixed
into the four corners of a glass plate which is laid on top of the document or other matter to be copied.
