DSLR’lar video \u00e7ekerken, foto\u011fraf \u00e7ekimlerinde kullan\u0131lan optik alg\u0131lay\u0131c\u0131lar ile odaklanman\u0131n aksine, alg\u0131lay\u0131c\u0131 tabanl\u0131 bir otomatik odaklanma sistemi kullan\u0131yorlar. Bu noktada belirtilmesi gereken ise, alg\u0131lay\u0131c\u0131 tabanl\u0131 sistemlerin\u00a0sadece<\/a>\u00a0kar\u015f\u0131tl\u0131k de\u011ferlerini taban alarak sa\u011flad\u0131klar\u0131 otomatik odaklanma sisteminin s\u00fcrekli \u00e7al\u0131\u015fmak i\u00e7in \u00e7ok yava\u015f olmas\u0131.
