Arrangement for carrying out a method for the purpose of error compensation in the case of the panel control in a one-eyed lens reflexe type with interchangeable objective

摘要

a one eyed camera with blendenautomatik and metering by the fully opened lens (ttl measurement) errors.the differences of wechselobjektivs against a referenzobjektiv and based on different intensity of light emitted, and different from the optical properties of the lenses and the special einbauposition of the element for measuring the objekthelligkeit caused beleuchtungsf ehler backwith the help of a leerweg corresponding vorverschiebung in blendenantriebsmechanismus compensated. the vorverschiebung is thus realized that between two, preferably on a feather together gekuppelten, members (41, 43) of the blendenantriebsmechanismus a relative movement (), while the blendensteuerschaltung (fig.2) to be entered, but no effective movement of the blendenlamellen result. the size of this relative movement is provided by the wechselobjektiv attack (32) are adjustable, the position of a (41) of the two blendenantriebsglieder (41, 43).
