I I I I I www.orphancameras.com -J: J Lil J *l {c ,# t E The fact that the Leica cameramay be fitted with a completeseries of inter- changeable,coated lenses which coupleto the rangefinderof all Leicacameras is one of the most important characteristicsof the Leica systemof photography. H The principle of interchangeabilityis not new, but as developedand ipflidd to the Leica camera,it has mad I been e avallable to a far greater numb6r of .{.:l photographersthan was previouslypossible. di The Helicol Mount. Eachlens is provided with its own focusingmount. On 1 all lensesexcept Summarit 50mm. and long focus lenses,focusing is effected , by meansof a l^ever.On the other lensesa milled ring is provided.Th. distun.e d E is read off by an index mark. Collopsible lens Mounts. The LeitzElmar and Leitz Summicron of jomm., focal length are providedwith collapsiblemounts, and must be pulled out be- fore using the cainera.\7hen the leni is fully drawn out, it is turned slightly to I the right, where it locks in position.To push back the lens, it musthrst be turned a little to the left, then pushedstraight back into the body of the camera. -f- The lnfinity Cotch. N7henthe focusingmounts of the Hektor 28mm., Sum- Lr maron 35mm.,and Elmar, Summicronand Summarit)Omm.. lenses reach the "infinity" pulk: theylock in_position by meansof a catch.By pressingthe knob on the end of the focusinglever, the catchis releasedand can thenbe rotated for focusing.This deviceis only found on lensesof 28, 35 and 50mm., focal ; length. The Aperture is seton the Leitz Elmar 50mm.and Hektor 28mm.,by a small lever engravedwith an index to the front ring of the lens mount. On lhe other T lenses,a narrow ring bearing the index mark, actuatesthe diaphragm. The figures indicate the relative aperture of the lens. In the following Pageswe state that a lens is of Gauss-typeconstruction. I t$7hatdoes that mean? Gauss-typeconstruction is basedon a formr-rlawhich was devisedby Gaussin the 1880's.Originally, he simply took two identical Aplanatic lensesand mounted them end to end with an iris-diaphragmin bdtween.In other words, he combinedtwo identical lens systemr,...i o.r. c independentlywell-corrected. When he took thesetwo lensesand combined them into one lens, and placedthe iris-diaphragmin between,he was able T to still further improve chromaticaberrations. www.orphancameras.com ...s.&i*r. s_ rJ HEKTOR2Bmm", f/6.3 {When Avqiloble) Leitz extreme rlide angle (76 cleg.) lens. is the Hektor 28mm., f 7'6.3, tlcsigned as a tripiet r,r'ithtu'o ccmentcd surfaces.u'hich has been vu'idelyusecl for correction.Er-en at full aperture (f t'6.3), n'hich in a systemof such a large angle of vieu' must be regarded as high, it gives remarkable sharpness to the Lejca format without distortion-a novel feature in view of the very short focal length. In this objective, too, the requirement of extensivereduc- tion of vignetting has been taken into considerationby making the lens largcr than the dimension corresponding to the relative aperture. Proper reduction o.f the aperture. which is_always advisable for wide-angleobjectives if concii- tions permit, resultsin a further increaseof the quality of the image (optimurrr ai)proximatelyat f/ l1), and an in-rproveddistribution of light over the entire I rI age ?1rea.
