• Meyer-Optik - Zwischen 29 und 500 (1966).

Manufacturer description

Aus dem "Meyer-Optik - Zwischen 29 und 500" (1966):

Der besondere Vorzug dieses Meyer-Standardobjektivs ist seine extrem hohe Lichtstärke. Oberall dort, wo ungünstige Lichtverhältnisse ein erfolgreiches Arbeiten bisher nicht mehr zuließen, wird dieses Objektiv gute Dienste leisten und seinem Besitzer die Möglichkeit geben, das Durchschnittsniveau zu überragen. Nächtliche Straßenszenen, Sport- und Theateraufnahmen erweitern das Aufnahmegebiet. Der kürzeste Aufnahmeabstand ohne Zwischenringe liegt bei 23cm, gemessen von derVorderkante des Objektivs bis zum Aufnahmegegenstand. Die spezielle Eignung des Oreston für Nahaufnahmen liegt somit auf der Hand.

***

The special advantage of this Meyer standard lens is its extremely high speed. Wherever unfavorable lighting conditions have previously prevented successful work, this lens will do a good job and give its owner the opportunity to surpass the average level. Street scenes at night, sports and theater shots expand the recording area. The shortest shooting distance without extension rings is 23cm, measured from the front edge of the lens to the subject. The special suitability of the Oreston for close-ups is therefore obvious.

From the Exakta Equipment Information Service (No. 576)

Very few people know that they can use the Oreston in their Exakta VX-1000 or older models. Most people believe that the Oreston can be used only in the Exakta RTL. While the internal automatic will work only in the RTL, there is no reason why owners of a "classic" Exakta should deprive themselves of the Oreston. The lens will be wide open for focusing and composing (at a brilliant F1.8!). When you take your picture you depress a "button" on the rim of the lens and it will close down to the taking aperture. Take your finger off, and the lens automatically opens up to F1.8. Although this is not "fully automatic," it is the closest thing to it and certainly far more convenient than a preset lens. (In the Exakta RTL the Oreston is "fully" automatic, of course.)

From the editor

Introduced at the 1965 Leipzig Spring Fair.

The lens was produced in two versions:

• "auto" - a lens with plain M42 screw mount with the pin for automatic stop down;
• "electric" - as "auto", but also with electrical contacts for compatible Praktica models.

However, unlike the later Pentacon version, the name of the lens did not contain the words "auto" or "electric".

For the Exakta RTL 1000, the lens was produced in version with automatic diaphragm mechanism with internal release.
