3.2Focusing
It ispreferabletoperformfocusing atmaximumaperture byrotatingthe focusing ring 1,on whichfocusing scale(distance) 2is
marked.Iffocusing isrequired after tilting and shifting the opticalblock, then the microprismsor camera viewfinder wedges’surfacedim
out. Inthiscaseitisnecessarytocontrolimage sharpnessaccording tothe screen’smattearea.The distancescale2canbe used
instead togivean approximatefocus.
During opticalblocktilting and shifting,decreasethe aperture asfar aspossible,becauseunequalamounts ofthe lightfallson the
edges and center ofthe field.Itis recommendedtousethe aperture values from16 to22.
When focusing the lensafter ithasbeen shifted,itispossiblethatthe microprismand the split-imagerangefinder ofthe viewfinder
ofthe camera maydarken.Inthatcase,checkthe image sharpnesson the mattespotofthe focusingscreen.Orientation based on a
distancescaleafter the lens has been shifted shallnot givepreciseresult.
3.3.Apertureoperation
Manualaperture operation is provided for inthelens. Select the value byrotation of the ring 5, first pulling it aside along the optical
axistowardsthe camera.Inthe released condition rotatethe ring 5fromsetup value tothe value2,8.Before exposuredo notforgetto
rotatethering 5untilthe selectedvalue of theaperture appears.
3.4.Lensshifting
Whilerotating handle10,the lensismoving inparalleltothe imagesurface.The lenscan be rotated by360оwithsettled interval
every30 о(the lenscan operateeven inthe positionsbetween theseintervals).Due tothe factthatthe camera’simage isrectangular,
the limitdegree oflensshiftwill be changing ateveryrotation.The maximalshiftispossibleatthe settled position ofthe lensalong the
image’sshortside.Controlthis shift onthescale11.
3.5.Lenstilting

rotated by360оwithsettled intervalevery30 о(the lenscan operateeven inthe positionsbetween theseintervals).Due tothe fact that
the camera’simage isrectangular,the limitdegree oflenstiltwill be changing ateveryrotation.Themaximaltiltispossibleatthe

tiltanglewiththe zero position ofthe shift.

3.6.Lensrotating
The lenscan be rotated by360оwithsettled intervalevery30 о(the lenscan operateeven inthe positionsbetween these
intervals).For 360olensrotating justrotatethe ring9clockwiseor counter-clockwise. Whenlensinstalled on the camera body, you can
rotatethemalsoholding lens bodyor TSplate6.
3.7. Distortioncorrection
When photographing high buildingsfromground level,the distancesfromthe lensfromthe top andbottomofthe subjectare
radicallydifferent.Asaresultofthis, the distortion inthiscaseappearsasaconvergenceofthe parallellinesupwards(Figure 4),and
viceversa:when photographing fromabovedownwards, the parallelsides ofthe buildingwill be converging downwards.
Figure 4
Inorder tocorrect suchdistortion do notincline the camera either upwardsor downwards, but maintainthe filmplane inparallel
totheobjectbeing photographed (for example,building),thusthatfilmplaneofthe camera issituated atrightanglestothe ground.
Then,inorder toachievethe intended composition the opticalblock ofthe lensshall be shifted verticallyupwards, due tothisthe
distortion is eliminated.See Figure 5.
Figure 5
Sometimesinstead ofimage correction,withthe intention ofcreating specialeffects,the occasion arisestocreateeven more
exaggerated distortions.Inthiscase,you wouldincline the camera upwards and shift thelensinthe oppositedirection.
3.8. Reflection elimination
When photographing objectswithreflectivesurfaces,the reflectionofthephotographer along withcamera can appear on the
image.(Figure 6А).Carrying over the camera angletoone side and shifting the lens tothe oppositeside,whileretaining the parallelism
ofthe object and filmplanesallowsyoutoeliminatethe reflection and still preservethe rectangular composition ofthe image (Figure
6B).

3.9.Panoramas
Whileusing alenswithshiftcapabilityyou can producepanoramicphotographs. For that,maketwoexposuresfromone camera
angle:firstone –withmaximumshift of the lens tothe right,and asecond one –withmaximumshifttothe left.Combining bothimages
will provide you withasinglepanoramicphotograph (Figure 7),whichcorrespondstoanegativewithan image formatof6х9 сmand
normalperspective.

3.10. Obstructionelimination
Obstructionsliketreesor telegraph poleslocated relativelycloselytothe camera and appearing atthe image edge can be
eliminatedby means oflensshiftingand rotatingthecamera.
For instance,the obstruction (pole) islocated attheimageedge onthe right. See Figure 8А.Toeliminateit,shiftthe lenstothe
right, and rotatethe camera tothe leftuntilfulldisappearanceofthepole. (Figure 8B).

The camera lensisacomplicatedopticaldeviceand itrequirescarefuloperation and maintenance.Protectitagainst impacts,
sudden fluctuationsintemperatureand alsoagainst dustand moisture.
Upon entranceintoawarmroomfromoutside frost do notopen thelensimmediately.Letitwarmup topreventcondensation on
the opticalsurfaces.
Removedustand moisture fromthelenswithasoftbrush,cloth, or aproductspecifictothis purpose.
Note: During inspection itcan be found out thatsomelensesmayhavesmall bubbles inthe glass, insignificantscratches and fluffs
whichdo not inanywayaffect image qualityand havebeen acceptedbythe ARAXstandard.
