Viltrox Air AF 9/2.8 XF 9mm
{ "review": "Il campo visivo ultra-grandangolare di 113.8° e l'obiettivo f/2.8 con 13 elementi in 11 gruppi, inclusi lenti ED e asferiche, garantiscono nitidezza da bordo a bordo su corpi APS-C Sony E. Il peso di soli 176 g, la messa a fuoco ravvicinata a 13 cm e la porta USB-C per aggiornamenti firmware lo rendono uno strumento portatile e facile da mantenere, perfetto per vlogging e primi piani creativi. È la scelta ideale per fotografi di strada e appassionati di macro con punteggi rispettivamente di 93.7 e 95.7 su 100, che cercano un'ottica luminosa e maneggevole per il sistema Sony E." }
