Zithini izinto zeskena? Ukucoca i-lens yeskena?

Yintoni ukusetyenziswa kweiskenaIngiilensi? I-lens yeskena isetyenziswa ikakhulu ekufumaneni imifanekiso kunye nokuskena okukhethekileyo. Njengomnye wezinto eziphambili zeskena, ilensi yeskena ikakhulu inoxanduva lokufaka imifanekiso kwaye iguquguqule ibe yimiqondiso ye-elektroniki.

Inoxanduva lokuguqula iifayile zoqobo, iifoto, okanye amaxwebhu kwiifayile zemifanekiso yedijithali, ezenza ukuba zilungele abasebenzisi ukugcina, bahlela, kwaye babelane ngezixhobo zedijithali okanye ezinye izixhobo zedijithali.

Yintoni iskenaIngIzinto zeLensi?

I-lens yeskena iqulathe izinto ezahlukeneyo, eziqinisekisa ukuba iskena zinokubamba imifanekiso ecacileyo nechanekileyo:

Ilensi

I-lens yeyona nto iphambili yeUkuskena iilensi, isetyenziselwa ukugxila ukukhanya. Ngokuhlengahlengisa indawo yeelensi okanye usebenzisa iilensi ezahlukeneyo, ubude obujolise ngaphakathi kunye ne-aperture inokutshintshwa ukuze ufezekise iziphumo ezahlukeneyo zokudubula.

I-lens yeskena

I-aperture

I-Aperture yi-Aperture i-Aperture ekhoyo embindini weelensi, esetyenziselwa ukulawula isixa sokukhanya okungena kwilensi. Ukulungelelanisa ubungakanani be-adrture kunokulawula ubunzulu bentsimi kunye nokukhanya kokukhanya okudlula kwilensi.

FI-Ocus iringi

Iringi egxile kwisixhobo esijikelezayo esisetyenziselwa ukuhlengahlengisa ubude beelensi. Ngokujikeleza iringi egxile kuyo, iilensi zinokuhambelana nesihloko kwaye zifezekise kugxile kugxile.

AI-UTOFOCUS

Ezinye iilensi zokuskena zixhotywe nge-Autofocus. Aba bavo banokulinganisa umgama wento efakwe ifoto kwaye ilungelelanise ngokuzenzekelayo ubude beelensi zokufezekisa isiphumo se-Autofocus ngokuchanekileyo.

Itekhnoloji yokunyibilika

Abanye baqhubela phambiliUkuskena iilensiingaba ingaba neteknoloji yokulwa. Itekhnoloji inciphisa umfanekiso oxutywe obangelwe ngesandla sokungcangcazela ngokusebenzisa izilotha okanye izixhobo zoomatshini.

Ukucoca iskenaIngI-lens?

Ukucoca i-lens yeskena ikwangumsebenzi obalulekileyo, kwaye ukucoca ilensi linyathelo eliphambili ekugcineni umsebenzi wayo kunye nomfanekiso womfanekiso wayo. Kuya kufuneka kuqatshelwe ukuba ukucoca i-lens yeskena kufuna ukhathalelo olukhulu ukuthintela umonakalo kwi-lens. Kungcono ukucoca ilensi ngengcali okanye ibonisane neengcebiso zabo.

Ilensi yeskena

Ukucoca i-lens yeskena kubandakanya la manyathelo alandelayo:

1.Amanyathelo okulungiselela

1) Cima iskena ngaphambi kokucoca. Ngaphambi kokucoca, nceda uqinisekise ukuba iskena icinyiwe kwaye inqunyulwe kumandla ukuphepha nayiphi na ingozi yamandla.

2) Khetha izixhobo ezifanelekileyo zokucoca. Nika ingqalelo ekukhetheni izixhobo ezenzelwe ngokungqalileyo ukucoca iilensi ze-lens, njengephepha le-lens iphepha lokucoca, ii-balloons, njl njl, njl njl.

2.Sebenzisa i-balloon ejector ukususa uthuli kunye nokungcola

Okokuqala, sebenzisa i-balloon ijelocy yokuvuthuza kancinci kunye nokungcola kwi-lensi, ukuqinisekisa ukuba i-elt isetyenziselwa ukuphepha ukongeza uthuli olungaphezulu.

3.Ukucoca iphepha le-lens

Songa okanye i-curl isiqwenga esincinci sephepha elincinci elincinci, emva koko yinyusele kancinci kumphezulu welensi, unononophelo ungacinezeli okanye ukhulise indawo yelensi ngamandla. Ukuba kukho amabala anenkani, ungalahla ithontsi elinye okanye ezimbini zesisombululo esikhethekileyo sokucoca i-lens kwiphepha lokucoca.

4.Nika ingqalelo ukucoca kwicala elifanelekileyo

Xa usebenzisa iphepha lokucoca, qinisekisa ukuba ucoceke kwicala elifanelekileyo. Ungalandela ukhokelo lwentshukumo yolwaluko evela kwiziko ukuphepha ukushiya i-fibred okanye i-fibred fibred fir kwilensi.

5.Nika ingqalelo kwiziphumo zokuhlola iziphumo emva kokugqiba ukucoca

Emva kokucocwa, sebenzisa iglasi eyongeza iglasi okanye isixhobo sokujonga ikhamera ukujonga ukuba i-lens yelensi icocekile kwaye ingena kwintsalela okanye amabala.
