Canon USA acaba de comunicar un problema que se ha detectado en el funcionamiento del AF del nuevo objetivo 40mm/2,8 STM Pancake. Parece ser que al presionar sobre la barrera al montarse el objetivo (al quitarlo o presionar), puede detenerse el funcionamiento del AF. En condiciones normales de trabajo no aparece este problema. El problema se solucionará con un nuevo firmware que estará disponible en la Web de Canon a finales de Agosto. Mientras tanto, si sucede el problema, desmontar y mongtar de nuevo el objetivo.
