Yintoni i-lens egxile kuyo?

Njengoko igama libonisa, aI-lens ekugxilwe kuyoluhlobo lweelensi zokufota kunye nobude obusigxina, ezingenakulungiswa kwaye zihambelana nelensi yesoom.

Ukuthetha ngokuthetha, ukugxininiswa kwezimilo ezihlelelekileyo ngokuqhelekileyo kunye ne-aperture enkulu kunye nomgangatho ophezulu obonakalayo, owenza ukuba balungele ukuthatha iifoto ezikumgangatho ophezulu.

Umahluko phakathi kweelensi ekugxilwe kuzo kunye neelensi zoom

I-lens yokujonga ngokuhlelelekileyo kunye neelensi ze-zoom ziintlobo ezimbini eziqhelekileyo zeelebhu zekhamera, kwaye umahluko wabo ulele ekubeni ubude bezinto ezimbi zihlengahlengiswa. Banazo izibonelelo zabo xa zisetyenziswa kwiimeko ezahlukeneyo zesicelo.

Umzekelo, iilensi ekugxilwe kuzo zilungele ukusetyenziswa kwiimeko zokukhanya okwaneleyo, ukufuna imixholo ephambili, kunye nemixholo eshukumayo, kunye nelensi yokudubula, ngelixa ilensi ilungele ukusondeza okubonakalayo, njengefoto yezemidlalo.

I-lens ekugxilwe kuyo

Ubude obujolise kuyo

Ubude obugxile kwilensi yokugxila ekugxilwe kuyo buyenzile, njenge-50mm, 85mm, njl njl, kwaye ayinakulungiswa. Iilensi ze-ZOOM zinokulungelelanisa ubude bokugxila ngokujikeleza okanye ukutyhala nokutsala i-lensi yelensi, ivumela ukhetho olutshintshelekileyo phakathi kwe-angle enkulu kunye neTelephoto.

OIntsebenzo ye-Ptical

Ngokubanzi, aI-lens ekugxilwe kuyoUnomgangatho ongcono welensi yelensi ye-zoom kuba uyilo lwayo lulula kwaye alufuni kuqwalaselwa intshukumo ye-lens okanye izakhiwo ezimbaxa. Ukuthetha ngokuthetha, ukugxininiswa kwezimilo ezihleliweyo ngokwesiqhelo (ngexabiso elincinci le-F), elinokubonelela ngomgangatho womfanekiso ongcono, ukuvelisa okukhulu, kunye neziphumo zemva kokomva.

Kodwa ngoku ngophuhliso lwetekhnoloji, ezinye iilensi eziphakamileyo zinokufikelela kwinqanaba leelensi ezigxile kuzo ngokwendlela yokusebenza.

Ubunzima kunye nevolumu

Ubume beelensi ekugxilwe kuzo bulula, bulula kwaye bukhaphukhaphu ngokobukhulu. Ubume beelensi ze-zoom bunzima, bubandakanya iilensi ezininzi, ngoko ke zihlala zinzima kwaye zikhulu, ezinokungabi lula kakhulu ukuba iifoto zisebenzise.

Indlela yokudubula

I-lense egxiles zilungele ukudubula imiboniso okanye izifundo, njengoko ubude bokugxila azinakulungiswa, kwaye iilensi ezifanelekileyo kufuneka zikhethwe ngokusekwe kumgama wokudubula.

Ilensi yesondeza iguquka kwaye inokulungelelanisa ubude bezinto ezigxile ngokokudubula ngaphandle kokutshintsha indawo yokudubula. Ilungele imihlo efuna utshintsho oluguqukayo ekudubeni umgama kunye ne-engile.
