I fnecessary, the shutter can be set bet-ween the values e. g. 1/zs sec. between50 and 100. Exception: Do not set bet-ween 10 and 25 as well as with higherspeeds than r/no sec. For the "T" ad-justment (Prontor S only), the shutteropens when the tr igger is f i rst pressedand closes when i t is pressed a se-cond t ime.

For the "8" adjustment, however,. theshutter remains open as long as thepressure on the release lever is

maintained. The various markingsare

6. Finder and ReleaseWhen the camera is opened, the op-tical finder 13 springi up into po_si t ion. Use i t for preference, s inceshots at eye level will then have themost natural perspect ive.Hold the camera as in f igs. 11 and 12,i . e. -press i t f i rmly against ' the faceand look through the rear lens of thef inder. The f ront lens indicates theexact angle of view. The whole rimof th is lens must therefore be v i -s ib le.For p ictures in the hal f -s ize, 2r /+ X Is/eins. , br ing up the smal l s ize mask jn_to the f rame; th is mask is h inqed tothe f ront port ion of the f inder.Close the finder by simply pushingdown the cover, db nof iorictr thelenses.

The Correct Tim6- oi-ffibsureThe modern ,amateur film with aspeed of approx. 27-280 Scheiner(1.71100 DIN) has an extensive lat i tudeof exposure so that yeu need not beextremely careful when exposing.However, as general rule you shouldalways keep in your mind: you willget the best pictures with an expo-sure which is also sufficient for theshadows!

This indicates that' they are "coated"i. e. f i t ted with

"anti retlection laYers".The AR layers obviate reflection oflight rays as a result of "counter-l ight" i . e. they reduce i t to a mini-mum; at the same time they increasethe brill iance of the pictures and thetransmission power of the lens.Even uncoated Ienses require verYcareful treatment; the outer surfacesof lenses with AR laYers should betreated with especial care. These lay-ers are very hard, but theY are ex-tremely thin (aPP. 1/ro ooo mm.)The lens must be cleaned with a f inehair brush or a very soft cloth.
