1.Keď je hlavný objekt v zaostrovacom rozpätí relatívne malý

Keď osoba stojaca pred vzdialeným pozadím je umiestnená v zaostrovacom rozpätí ako na obr. C, pozadie môže byť zaostrené a objekt nie.

2.Keď je hlavným objektom scéna alebo predmet s jemným vzorom

Keď má objekt jemný vzor alebo nemá dostatočný kontrast, ako napríklad pole plné kvetov ako na obr. D, zaostrovanie pomocou automatického zaostrenia môže byť náročné.

Ako riešiť tieto situácie

(1)Zaostrite na iný predmet umiestnený v rovnakej vzdialenosti od fotoaparátu, uzamknite zaostrenie, zmeňte kompozíciu a nasnímajte záber.

(2)Nastavte režim zaostrovania fotoaparátu na manuálny a objekt zaostrite ručne.
