Amaphutha ajwayelekile ukugwema lapho ukhetha ama-lens wombono womshini

Lapho ukhetha aumshini wokubuka umshini, kubucayi ukuthi ungakunaki ukubaluleka kwako ohlelweni oluphelele. Isibonelo, ukwehluleka ukubheka izici zezemvelo kungahle kube nomphumela ekusebenzeni kwamalensi angaphansi komhlaba kanye nomonakalo ongaba khona kumalensi; Ukwehluleka ukubheka ukuxazulula izingxoxo nezidingo zekhwalithi yesithombe kungahle kube nomphumela ekubanjweni kwezithombe nokuhlaziywa okunganele.

1, ungakunaki ukubaluleka kwelensi ohlelweni

Iphutha elijwayelekile lokugwema lapho ukhetha ama-lens wombono womshini ukuwabheka ukuthi i-lens ibaluleke kangakanani ohlelweni. Nazi izizathu ezintathu ezibalulekile zokuthi ama-lenses abucayi kwizicelo zombono womshini:

(1)Isilinganiso sesithombe sezithombe ezinhle kakhulu

Ilensi idlala indima ebalulekile ekuthumbeni izithombe ezisezingeni eliphakeme. Inquma izici ezifana nesixazululo, ukuhlanekezela, kanye nokunemba kwemibala. Ukukhetha ilensi efanele kuqinisekisa ukuthi uhlelo lungahlaziya kahle izithombe ngokunembile futhi lwenze izinqumo eziqondile.

(2)Inkambu efanelekile yokubuka

I-lens inquma inkambu yokubuka, okuyindawo leyo ikhamera engayithatha. Kubalulekile ukukhetha lens ngobude obufanele bokugxila ukuze uqinisekise ukuthi ufaka indawo oyifunayo bese uthwebula imininingwane edingekayo.

(3)Ukuhambisana namakhamera nokukhanyisa

Amalensi kufanele ahambisane nekhamera yakho nokusetha ukukhanyisa ukufeza ukusebenza okuhle. Cabanga ngezinto ezifana nohlobo lwe-Lens 'Mount, usayizi we-sensor, nebanga lokusebenza ukuze uqinisekise ukuhlanganiswa okungenamthungo kanye nohlelo lwakho lonke.

2,Akukho ukucatshangelwa kwezici zezemvelo

Okuhlangenwe nakho kwabantu abaningi ukuthi izici zezemvelo zivame ukungabhekwa lapho zikhethaAmalensi wombono woMshini. Bayabona okuncane ukuthi lokhu kubhekwa kungadala izinkinga ezinkulu ngokusebenza nokuphila kwelensi.

Izici zezemvelo ezifana nezinga lokushisa, umswakama, nothuli kungathinta kabi i-lens futhi ekugcineni ukunemba kohlelo lombono womshini. Izinga lokushisa elibi kakhulu lingadala ukuthi ilensi ikhubazeke noma ithinte izinto zangaphakathi, ngenkathi umswakama ophezulu kungadala ukuvumelanisa nokungena ngaphakathi kwelensi.

Ngokwengeziwe, izinhlayiya zothuli zinganqwabelana ebusweni belensi, zibangele ukucekelwa phansi kwesithombe futhi kulimaze amalensi. Ngakho-ke, kubalulekile ukuhlola kahle izimo zemvelo lapho uhlelo lokubona lomshini luzosebenza khona bese ukhetha ilensi eklanyelwe ukumelana nalezo zimo.

3,Ikhwalithi yesimo nekhwalithi yesithombe ayibhekwa

Ngabe siyabheka ukulungiswa nekhwalithi yesithombe lapho ukhethaAmalensi wombono woMshini? Ukucabanga ngalezi zinto kubalulekile ekuqinisekiseni imiphumela enembile nethembekile. Nawa amanye amaphutha ajwayelekile okufanele uwagweme:

(1)Ziba izidingo zokuxazulula:

A.Uma isixazululo selensi asihambelani nokuxazululwa kwenzwa yekhamera, umphumela uzoba ukucekelwa phansi kwesithombe kanye nokulahlekelwa imininingwane ebalulekile.

B.Khetha i-lens ngesinqumo esiphansi kunalokho okudingekayo kuzokhawulela amandla ohlelo ukuze uthole kahle izinto.

(2)Unganaki ukuhlanekezela kwesithombe:

Ukuhlanekezela kwe-A.lens kungathinta ukunemba kwezilinganiso futhi kuholele kumaphutha wokuhlaziya.

B.Ukuqonda izici zokuhlanekezela zelensi bese ukhetha ilensi ngokuhlanekezela okuncane kakhulu kubucayi izinhlelo zokusebenza zombono womshini onembile.

(3)Unganaki i-lens coating nekhwalithi ye-optical:

A.Cooatings anciphisa ukuboniswa futhi athuthukise ukuhanjiswa okukhanyayo kwamalensi, okuholela ezithombeni ezicacile.

B.Khetha ama-lens asezingeni eliphakeme ngokusebenza okuphakeme okuphezulu anganciphisa ukuhlukunyezwa futhi aqinisekise okucacile, izithombe ezinembile ngokwengeziwe.

Imicabango yokugcina:

UChuangan wenze ukwakheka kokuqala nokukhiqizwa kweAmalensi wombono woMshini, ezisetshenziswa kuzo zonke izici zezinhlelo zombono womshini. Uma unentshisekelo noma unezidingo zamalensi wombono womshini, sicela uxhumane nathi ngokushesha okukhulu.
