lens Modern (okt lens zinika aberration chromatic) usebenzisa esezantsi-kwiintsali izinto ukunika refraction ngaphantsi kunye umfanekiso ocace. Xa lens Nikon ukuba zibonakaliswe yi ED (kwiintsali Extra-Low) mqondiso. Ukulungiselela le njongo ziyasetyenziswa lens aspherical, singavumeli umfanekiso kunye nenani elincinci ezo ziphene. Kukho kwakhona iikhamera kunye ulawulo oluzenzekelayo aberrations.

Kodwa ukuba ilens ekhoyo namanje inikeza ezi igqwethwe, zininzi iindlela ukujongana nazo.

Eyona ngokuqhelekileyo kwenzeka chromatic lens aberration ukuba ubuninzi enkulu zoom. Le nto ukuba ubude ezahlukeneyo focal, ezi igqwethwe okanye zibonakale ngeendlela ezahlukeneyo, kunzima kakhulu kwaye ngoko ukubala ukumelana zonke iziphene kunokwenzeka kuhlelo ezintsonkothileyo. Le nto iilensi kunye esisigxina ubude, ukunika umfanekiso ngcono kwaye zikholisa kakhulu eninzi ngaphezu "Zuma".

Kukho nezinye aberrations yeenkqubo ezamehlo. Xa usebenzisa lens ungqukuva ukuba aberration ungqukuva ngenxa umahluko ukusasazwa ukhanyiso embindini kunye kungqameko lens. Oluvakaliswe isiphene kwi ukuthambisa ajikeleze esikhumbuza halo. Ukuze enze umfanekiso olubulala kunye aberrations ezifana isiqaqa astigmatism.
