He also established a friendship and collaboration with the photographer Iosif Bernea and the painter Victor Brauner, and was close to the writer and future Orthodox hermit Nicolae Steinhardt. After 1930, he was involved in polemics with traditionalist young authors, including poet Otilia Cazimir (whom he accused of writing with "hypocrisy") and members of the eclectic grouping known as "Criterion" (who, he claimed, were guilty of "ridicule and opportunism"). His relations with Arghezi also grew more distant, after Bogza expressed disapproval for Arghezi's 1930 decision to collaborate with the Romanian Radio—Geo Bogza drew attention to his older colleague's previous public statements, in which he had criticized the national station on various grounds.
