It is suitable for a deliberate working method with clearly separated decisions: choose the location and framing, set the distance, and then determine the aperture to suit the light and desired depth of field. The M42 mount offered here is distinct from the Exakta versions that also exist.\u003c\/p\u003e\n\n\u003ch3\u003eFocus Wide Open, Stop Down for Exposure\u003c\/h3\u003e\n\n\u003cp\u003eWith the automatic diaphragm, the working aperture is preselected on the lens. The appropriate M42 camera mechanically actuates the diaphragm pin so that the aperture closes for metering or exposure. This allows the viewfinder to remain open and bright when setting the focus. On an adapted camera, the adapter solution must take this process into account; a simple thread ring does not replace the actuation of the pin.\u003c\/p\u003e\n\n\u003ch3\u003eClose-Up Range and Filter Thread\u003c\/h3\u003e\n\n\u003cp\u003eThe contemporary manufacturer's catalog lists a minimum focusing distance of 0.35 m and a 49 mm filter thread for this design. The distance is measured from the camera's image plane; it is not a free distance in front of the front lens. For small subjects, therefore, the achievable framing is also important in addition to the distance. Such a close-up range does not automatically guarantee life-size reproduction.\u003c\/p\u003e\n\n\u003ch3\u003ePurposefully Categorize M42 in Your Equipment\u003c\/h3\u003e\n\n\u003cp\u003eThe documented mount is the M42 screw system. This distinguishes this mount from Praktica-B bayonet lenses and from lenses of the same name with an Exakta mount. For a mirrorless camera, a suitable adapter can enable use with manual focus and a working aperture. The lens mount is the deciding factor; the inscription Praktica, Zeiss, or Pentacon alone does not determine a different mount.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Carl Zeiss\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eModel:\u003c\/strong\u003e Q1 Tessar 8 Blades Automatic\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Lens\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eLens Mount:\u003c\/strong\u003e M42\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFocusing:\u003c\/strong\u003e Manual\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFocal Length:\u003c\/strong\u003e 50mm\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMaximum Aperture:\u003c\/strong\u003e f\/2.8\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eColor:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch3\u003eScope of Delivery and Image Notice\u003c\/h3\u003e\n\n\u003cp\u003eThe product named in the title is supplied.\u003c\/p\u003e\n\n\u003cp\u003eAdditional accessories are only included if they are expressly mentioned in the title as part of the offer.\u003c\/p\u003e\n\n\u003cp\u003eThe product images shown above serve as examples.
