Yini ukusetshenziswascaningamalensi? Ilensi yokuskena isetshenziswa kakhulu ukuthwebula izithombe nokuskena kokubona.Njengenye yezingxenye eziyinhloko zesithwebuli, ilensi yesithwebuli inesibopho esikhulu sokuthwebula izithombe futhi iziguqule zibe amasignali kagesi.

Inesibopho sokuguqula amafayela oqobo, izithombe, noma imibhalo ibe amafayela ezithombe ezidijithali, okwenza kube lula kubasebenzisi ukugcina, ukuhlela, nokwabelana kumakhompyutha noma kwamanye amadivaysi edijithali.

Yini scaningizingxenye zelensi?

Ilensi yokuskena yakhiwe izingxenye ezihlukene, eziqinisekisa ukuthi ukuskena kungathatha izithombe ezicacile nezinembile:

Ilensi

I-lens iyingxenye eyinhloko ye-ukuskena ilensi, esetshenziselwa ukugxilisa ukukhanya.Ngokulungisa ukuma kwamalensi noma ukusebenzisa amalensi ahlukene, ubude bokugxila nokuvuleka kungashintshwa ukuze kuzuzwe imiphumela ehlukene yokudubula.

Ilensi yokuskena

Imbobo

Imbobo imbobo elawulekayo etholakala maphakathi nelensi, esetshenziselwa ukulawula inani lokukhanya elingena kulensi.Ukulungisa usayizi wokuvula kungalawula ukujula kwenkambu nokukhanya kokukhanya okudlula ilensi.

Findandatho ye-ocus

Iringi yokugxilisa ingqondo iyisisetshenziswa esiyindilinga esiphendukayo esisetshenziselwa ukulungisa ubude obugxilile belensi.Ngokuzungezisa indandatho yokugxilisa ingqondo, ilensi ingaqondaniswa nesihloko futhi izuze ukugxila okucacile.

Ainzwa ye-utofocus

Amanye amalensi okuskena nawo afakwe izinzwa ze-autofocus.Lezi zinzwa zingakala ibanga lento ethwetshulwayo futhi zilungise ngokuzenzakalelayo ubude bokugxila belensi ukuze kuzuzwe umphumela onembile we-autofocus.

Ubuchwepheshe be-Anti Shaking

Okunye okuthuthukileukuskena amalensiingase futhi ibe nobuchwepheshe be-anti shake.Lobu buchwepheshe bunciphisa ukufiphala kwesithombe okubangelwa ukuxhawula ngokusebenzisa izinza noma izinsimbi.

Indlela yokuhlanza iskenaingilensi?

Ukuhlanza ilensi yokuskena nakho kuwumsebenzi obalulekile, futhi ukuhlanza ilensi kuyisinyathelo esibalulekile ekugcineni ukusebenza kwayo kanye nekhwalithi yesithombe.Kumele kuqashelwe ukuthi ukuhlanza i-lens yokuskena kudinga ukunakekelwa okukhulu ukuvimbela umonakalo ebusweni be-lens.Kungcono ukuhlanza ilensi ngochwepheshe noma uthintane neseluleko sabo.

Ilensi yokuskena

Ukuhlanza ilensi yokuskena ngokuvamile kuhilela izinyathelo ezilandelayo:

1.Izinyathelo zokulungiselela

1) Vala isithwebuli ngaphambi kokuhlanza.Ngaphambi kokuhlanza, sicela uqinisekise ukuthi isithwebuli sivaliwe futhi sinqanyuliwe emandleni ukugwema noma yiziphi izingozi zamandla.

2) Khetha amathuluzi okuhlanza afanelekile.Naka ukukhetha amathuluzi aklanyelwe ngokukhethekile ukuhlanza amalensi okubona, njengephepha lokuhlanza ilensi, okokukhipha ibhaluni, amapeni amalensi, njll. Gwema ukusebenzisa amathawula ephepha avamile noma amathawula njengoba angase aklwebhe indawo engaphezulu yelensi.

2.Ukusebenzisa i-ejector yebhaluni ukususa uthuli nokungcola

Okokuqala, sebenzisa i-ejector yebhaluni ukuze ukhiphe ngobumnene uthuli nokungcola okuvela endaweni yelensi, uqinisekise ukuthi i-ejector ehlanzekile isetshenziswa ukugwema ukwengeza uthuli olwengeziwe.

3.Hlanza ngephepha lokuhlanza ilensi

Songa noma usonge ucezu oluncane lwephepha lokuhlanza ilensi kancane, bese ulihambisa kancane kancane endaweni engaphezulu kwelensi, uqaphele ukuthi ungacindezeli noma unwaye indawo engaphezulu yelensi ngamandla.Uma kukhona amabala anenkani, ungaphonsa eyodwa noma amabili esixazululo esikhethekile sokuhlanza ilensi ephepheni lokuhlanza.

4.Naka ukuhlanza ngendlela efanele

Uma usebenzisa iphepha lokuhlanza, qiniseka ukuthi uhlanza ngendlela efanele.Ungalandela isiqondiso sokunyakaza kwe-circumferential kusuka enkabeni ukuze ugweme ukushiya amamaki efayibha edabukile noma afiphele kulensi.

5.Naka imiphumela yokuhlolwa ngemva kokuqeda ukuhlanza

Ngemva kokuhlanza, sebenzisa ingilazi yokusondeza noma ithuluzi lokubuka ikhamera ukuze uhlole ukuthi ingaphezulu lelensi lihlanzekile futhi alinazo yini izinsalela noma amabala.
