Izimpawu Zamalensi Engilazi Asezingeni Elibi

Amalensi engilazi asezingeni eliphansi awagcini nje ngokuphazamisa ukubona kwakho kodwa futhi angabangela nokucindezeleka kwamehlo okungapheli isikhathi eside. Izinkinga ngala malensi zinezici ezintathu eziyinhloko: ukusebenza kokukhanya, ikhwalithi yezinto ezibonakalayo, futhi ikhwalithi yokumbozaNgokuqondile, zingabonakala ngokucacile ngezimpawu ezilandelayo ezibalulekile.

Ukusebenza Okubonakalayo

1. Ukucaca okunganele: Amalensi asezingeni eliphansi awakwazi ukukhiqiza isithombe esibukhali. Uma ubheka kuwo, izinto zingase zibe nemidwebo efiphele futhi zibonakale "zinsundu" noma "zinenkungu." Zibika ukuthi zibhekene nokukhanya okuphezulu lapho zishintshela kumalensi asezingeni eliphezulu, njengeZeiss, okubonisa ukuthi amalensi azo amadala kungenzeka ukuthi ayenezinkinga ezinkulu ngokudluliswa kokukhanya.

2. Inkomba yokubheka engalungile: Inkomba yokukhanya iyindlela ebalulekile yokuhlola ukusebenza kokukhanya. Amalensi asezingeni eliphansi angase angahambisani nenkomba yawo yokukhanya eshiwo. Isibonelo, ilensi ethengiswa njengenkomba ephezulu engu-1.74 ingase ibe nenkomba ephansi.

3. Ukuphazamiseka okukhulu kwe-chromatic: Amalensi asezingeni eliphezulu angalawula ngempumelelo ukusabalala kwe-chromatic, okusho ukugxila ekukhanyeni kwemibala ehlukene cishe endaweni efanayo. Nokho, amalensi asezingeni eliphansi avame ukuba nokusabalala kwe-chromatic. Uma ubheka umthombo wokukhanya omhlophe okhanyayo ngamalensi, ungase ubone i-halo enemibala ewuzungezile. Lesi simo saziwa ngokuthi i-chromatic aberration. Isibonelo, lapho ubheka ukukhanya okunamandla, kungabonakala okubomvu okusobala, okuluhlaza okotshani, okuluhlaza okwesibhakabhaka, noma eminye imiphetho enemibala. Lokhu kwenzeka ngoba ilensi iguqula ubude bamaza bokukhanya obuhlukene ngamazinga ahlukahlukene, okuthinta ikhwalithi yokubuka. Uma i-coefficient yokusabalala iphansi, lo mphumela uba mubi kakhulu. Yingakho inkomba yokubheka ephezulu ingabi ngcono ngaso sonke isikhathi.

4. Ukuphuzi kanye nokuguquguquka: Amalensi e-resin asezingeni eliphansi avame ukuba nezinto ze-monomer ezingazinzile. Ukuchayeka isikhathi eside elangeni noma ekukhanyeni kwangaphakathi kungabangela ukuthi ancibilike futhi aphenduke aphuzi ngokushesha (ngezinye izikhathi ezinyangeni ezi-3-6). Ngenkathi ophuzi engahlunga ukukhanya okuluhlaza okwesibhakabhaka, lokhu "kuphuzi okungasebenzi kahle" kuzoholela ekuphazamisekeni kombala futhi kunciphise ukudluliswa kokukhanya. Ngaphezu kwalokho, la malensi anokuqina kokushisa okubi. Ukuwashiya emotweni ehlobo kungabangela ukuthi ashintshe kancane, okuholela "ekushintsheni" kwamandla elensi. Ukugqoka amalensi anjengalawa ngomuthi ongalungile kungabangela ukubona kabili kanye nesiyezi, futhi kuzosheshisa ukuwohloka kwamehlo akho ngokuhamba kwesikhathi.

Ikhwalithi Yezinto Ezibalulekile

1. Ukumelana nokuklwebheka okubi: Uphawu oluphawulekayo lwamalensi asezingeni eliphansi ukuthi izindawo zawo ziyaklwebheka kalula. Ngesikhathi sokusetshenziswa kwansuku zonke, amalensi ezibuko zamehlo angathintana nezinto ezahlukahlukene njengezicubu nezingubo. Ngemva kwesikhathi sokusetshenziswa, izindawo zamalensi asezingeni eliphansi zizombozwa ngemihuzuko emincane eminingi.

2. Ukumelana nokunganamandla okunamandla: Amalensi asezingeni eliphansi avame ukuphuka uma ehlaselwa ngaphandle. Isibonelo, angase aqhekeke noma aqhekeke ngisho nalapho eshayisa into ngengozi.

3. Ukudlulisa ukukhanya okuphansi: Ngenxa yekhwalithi yezinto ngokwazo noma inqubo yokumboza engemihle, amalensi asezingeni eliphansi avame ukuba nokukhanya okuncane. Lo mehluko ubonakala kakhulu ezindaweni ezinokukhanya okuncane.

Ikhwalithi Yokumboza

1. Ukwehlukaniswa kokumboza: Izembozo zamalensi zinikeza imisebenzi eyahlukahlukene, njengokulwa nokukhanya, ukumelana namanzi, kanye nokumelana namafutha. Amalensi asezingeni eliphansi anamathela kahle ekumbozeni, okwenza izembozo zikwazi ukuxebuka.

2. Ukusebenza kabi kokulwa nokukhanya: Amalensi asezingeni eliphansi awenzi kahle ngokwezakhiwo zawo ezivimbela ukukhanya futhi akhiqiza ukukhanya okukhanyayo ezindaweni eziyinkimbinkimbi zokukhanya, njengokubuka ngefasitela ekamelweni elikhanyayo noma ukubuka isikrini sedivayisi kagesi ekukhanyeni okukhulu.

3. Ukumelana kwamanzi namafutha okwanele: Ubuso bamalensi asezingeni eliphansi abukwazi ukuvimbela ngempumelelo ukunamathela kwamanzi namafutha. Isibonelo, amaconsi amanzi noma amabala kawoyela azokwakheka kumalensi ngezinsuku zemvula noma ngemva kokuthinta izinto ezinamafutha.

Impendulo Yokugqoka Isikhathi Eside

• Amalensi aphansi agqokwa kalula: Ukuklwebheka okusobala kungavela kumalensi angenamandla ngemva kwenyanga eyi-1-2 yokusetshenziswa, ngisho noma kunakekelwe ngokucophelela nsuku zonke. Lokhu kubonisa ukuqina kwelensi okunganele. Ngokuphambene nalokho, amalensi asezingeni eliphezulu ane-coating eqinile ebusweni, enikeza ukumelana okuqinile kokuklwebheka.

• Ukukhanya okuncane kubangela ukukhathala kwamehlo: Ngemva kokuguga isikhathi eside, ungase uzizwe "amehlo ekhathala kalula" noma "entula amandla uma ubheka izinto". Uma amandla elensi engabhekwa njengembangela, kungenzeka ukuthi kungenxa yokukhanya okuphansi kwelensi. Amalensi asezingeni eliphansi aqukethe ukungcola okwengeziwe, okuthinta ukungena kokukhanya.

Ungakugwema Kanjani Amalensi Aphansi? Gxila Ezicini Ezimbili Ezibalulekile.

1. Yenqaba "ugibe lwentengo oluphansi kakhulu". Ungakhohliswa yintengo eshibhile ngendlela engakholeki yezibuko zamehlo ezinamalensi nohlaka. Ezinkundleni zokuxhumana nge-inthanethi, imikhiqizo enikeza "amalensi + ozimele" ngamashumi ama-yuan (isb., ¥39, ¥59) cishe iphansi impela. Izindleko zezinto eziyisisekelo kanye nopende lwamalensi asezingeni eliphezulu ziphakeme kakhulu. Ukuze kufezwe amanani aphansi kangaka, abathengisi banganciphisa kuphela izinqubo zokukhiqiza futhi basebenzise izinto eziphinde zasetshenziswa, ekugcineni kulimaze amehlo akho.

2. Beka phambili amalensi anophawu kanye nezici zokulwa nokukhwabanisa ukuze ugweme ingozi yokulimala kwamehlo ngamalensi angewona awemvelo. Izibuko zamehlo zingamathuluzi okubuka okugqoka isikhathi eside. Ukukhetha amalensi asezingeni eliphezulu akugcini nje ngokuthuthukisa ulwazi lokugqokwa kodwa futhi kuvikela impilo yamehlo akho. Uma ikhwalithi yamalensi inganakwa ngenxa yokufuna intengo ephansi, kungaholela ekulahlekelweni umbono futhi ekugcineni kudinge ukulungiswa okubizayo esikhundleni salokho.
