Yintoni ukusetyenziswascanngeiilensi? I-lens yokuskena isetyenziselwa ukufota imifanekiso kunye nokuskena kwamehlo.Njengenye yezinto eziphambili zeskena, ilensi yeskena inoxanduva ikakhulu lokuthatha imifanekiso kwaye iyiguqulele kwimiqondiso ye-elektroniki.

Inoxanduva lokuguqula iifayile zoqobo, iifoto, okanye amaxwebhu abe ziifayile zomfanekiso wedijithali, okwenza kube lula kubasebenzisi ukugcina, ukuhlela, kunye nokwabelana ngeekhompyuter okanye ezinye izixhobo zedijithali.

Yintoni iskeningeiinxalenye zelensi?

I-lens yokuskena yenziwe ngamacandelo ahlukeneyo, athi kunye aqinisekise ukuba ukuskena kunokuthatha imifanekiso ecacileyo nechanekileyo:

Ilensi

Ilensi yinxalenye engundoqo yeukuskena ilensi, esetyenziselwa ukugxila ekukhanyeni.Ngokulungelelanisa indawo yeelensi okanye ukusebenzisa iilensi ezahlukeneyo, ubude obugxilwe kunye nokuvula kungatshintshwa ukufezekisa iziphumo ezahlukeneyo zokudubula.

Ilensi yokuskena

Umngxuma wokuvula

Imbobo yimbobo elawulekayo ebekwe kumbindi welensi, esetyenziselwa ukulawula ubungakanani bokukhanya okungena kwilensi.Ukulungelelanisa ubungakanani bokuvula kunokulawula ubunzulu bentsimi kunye nokukhanya kokukhanya okudlula kwi-lens.

Fumsesane ocus

Iringi yokugxila sisixhobo esijikelezayo esisetyhula esisetyenziselwa ukulungisa ubude obugxilwe kwilensi.Ngokujikeleza i-ringing ringing, i-lens inokulungelelaniswa nesihloko kwaye ifezekise ukugxila okucacileyo.

Aisivamvo se-utofocus

Ezinye iilensi zokuskena zikwaxhotyiswe nge-autofocus sensors.Ezi zinzwa zinokulinganisa umgama wento efotwayo kwaye zilungelelanise ngokuzenzekelayo ubude be-lens ukufezekisa umphumo ochanekileyo we-autofocus.

Itekhnoloji yokulwa nokungcangcazela

Ezinye zihambele phambiliiilensi zokuskenainokuba nayo iteknoloji ye-anti shake.Le teknoloji inciphisa ukufiphala komfanekiso okubangelwa kukuxhawula ngesandla ngokusebenzisa izinzisi okanye izixhobo zoomatshini.

Indlela yokucoca iskeningeilensi?

Ukucoca i-lens yokuskena kwakhona ngumsebenzi obalulekileyo, kwaye ukucoca i-lens kuyinyathelo eliphambili ekugcineni ukusebenza kwayo kunye nomgangatho womfanekiso.Kufuneka kuqatshelwe ukuba ukucoca i-lens yokuskena kufuna ukunakekelwa okukhulu ukukhusela umonakalo kwi-lens surface.Kungcono ukucoca i-lens yingcali okanye udibane neengcebiso zabo.

Ilensi yokuskena

Ukucoca ilensi yokuskena ngokubanzi kubandakanya la manyathelo alandelayo:

1.Amanyathelo okulungiselela

1) Cima iskena ngaphambi kokucoca.Phambi kokucoca, nceda uqinisekise ukuba iskena sicinyiwe kwaye siqhawulwe kumbane ukuthintela naziphi na iingozi zamandla.

2) Khetha izixhobo ezifanelekileyo zokucoca.Nika ingqalelo ekukhetheni izixhobo ezenzelwe ngokukodwa ukucoca iilensi zamehlo, ezifana nephepha lokucoca ilensi, ii-ejectors zebhaluni, iipeni zelensi, njl.

2.Ukusebenzisa i-ejector yebhaluni ukususa uthuli kunye nokungcola

Okokuqala, sebenzisa i-ejector yebhaluni ukuvuthela ngobunono uthuli kunye nobumdaka obusuka kumphezulu welensi, uqinisekise ukuba i-ejector ecocekileyo iyasetyenziswa ukunqanda ukongeza uthuli oluninzi.

3.Coca ngephepha lokucoca ilensi

Songa okanye ugobe iqhekeza elincinci lephepha lokucoca ilensi kancinane, uze ulihambise ngobunono kumphezulu welensi, uqaphele ukuba ungacinezeli okanye ukrwele umphezulu welensi ngamandla.Ukuba kukho amabala anenkani, unokulahla enye okanye ezimbini zesisombululo esikhethekileyo sokucoca iilensi kwiphepha lokucoca.

4.Nika ingqalelo ekucoceni kwicala elichanekileyo

Xa usebenzisa iphepha lokucoca, qiniseka ukuba ucoce ngendlela efanelekileyo.Ungalandela umkhombandlela wentshukumo ejikelezayo ukusuka embindini ukunqanda ukushiya amanqaku akrazukileyo okanye amnyama kwilensi.

5.Nika ingqalelo kwiziphumo zokuhlola emva kokugqiba ukucoca

Emva kokucoca, sebenzisa iglasi yokukhulisa okanye isixhobo sokujonga ikhamera ukujonga ukuba umphezulu welensi ucocekile kwaye awunazo iintsalela okanye amabala.
