Indorerwamo za Varifocaligufasha guhindura uburebure bw'aho ufatira amashusho udahinduye aho ufatira amashusho, bitanga ubworoherane bukomeye no guhuza n'ibikenewe bitandukanye byo gufata amashusho, kandi bikoreshwa cyane mu gufotora ahantu nyaburanga.
Mu gufotora ahantu nyaburanga, guhitamo lenzi nziza ya varifocal bisaba gutekereza ku bintu nk'uburebure bw'ifoto, intego yo gufata amashusho, n'imiterere y'ahantu nyaburanga. Muri iyi nkuru, tuzasuzuma ibi bintu hamwe.
1.Imiterere y'ubutaka bunini
Mu gihe ufotora ahantu hanini, nk'imisozi, ubwatsi, ubutayu, n'inkombe z'inyanja, aho ubwiza bw'ibidukikije bugomba gufatwa, hakenewe ahantu hanini ho kureba, uburyo bwo kwagura, cyangwa uburebure bw'ahantu. Muri ibi bihe, lensi ifite inguni nini cyane irakwiriye, ifite uburebure bwa focal nka mm 10-24 cyangwa mm 16-35.
Urugero, iyo ufotora umusozi utwikiriwe n'urubura, lenzi ifite imiterere itandukanye ikoresha lenzi ifite imiterere yagutse cyane ishobora gufata amabuye ari imbere, ibimera biri hagati mu butaka, n'umusozi uri inyuma ufite imiterere ya rubura, bigaragaza uburebure bw'ikirere.

2.Ubuso bw'ubutaka buringaniye
Mu gihe ufotora ahantu haciriritse, nk'ibiyaga, imirima, cyangwa imiterere y'umujyi, ni ngombwa kugaragaza amakuru yihariye cyangwa isano iri hagati y'ikintu n'ibidukikije.indorerwamo za varifocal, zifite uburebure bwa focal nka 24-70mm cyangwa 24-105mm, zikwiriye iyi ntego, kuko zigaragaza ubusanzwe ingano n'isano y'ahantu habera.
Urusobe rw'amabara asanzwe ya varifocal lenses rukubiyemo uburyo busanzwe bukoreshwa, bigatuma habaho imiterere yoroshye no kuringaniza ahantu hose n'ibintu birambuye. Urugero, uburebure bwa focal bwa mm 50 bushobora gukoreshwa mu gufata urumuri n'igicucu mu ishyamba, mu gihe ingaruka zo gukanda uburebure bwa mm 70 zishobora gukoreshwa mu gushimangira ubwato buto ku kiyaga.
3.Imiterere ya kure
Gufotora ahantu ha kure, nk'imisozi n'inyamaswa zo mu gasozi, cyangwa ahandi hantu hatagerwa, bisaba lens ishobora gufata ibintu biri kure, gukanda ahantu, cyangwa kugaragaza ibintu birambuye. Muri ibi bihe, lens ya telephoto varifocal ifite uburebure bwa focal nka 70-200mm cyangwa 100-400mm irakwiriye. Ingaruka zo gukanda za lens ya telephoto zishobora gushyira ibintu biri kure, cyangwa zigatandukanya ikintu kiri inyuma, mu gihe gufata amashusho ari kure bifasha kwirinda kwangiza ibidukikije cyangwa kurinda umutekano w'umuntu.
Urugero, iyo ufotora imiterere y'imisozi ya kure, imiterere y'ibicu, cyangwa urubura ku mpinga z'imisozi, lensi ya telefoto ishobora kwegereza umuntu, ikagaragaza ibisobanuro birambuye n'imiterere; iyo ufotora imisozi ifite imiterere, imirima ifite imiterere, cyangwa amashyamba, ingaruka zo gukandagira kw'insi ya telefoto zishobora gutuma ishusho yumva uburebure n'ubugari.

4.Imiterere y'ubutaka irimo ibintu by'abantu
Mu gihe ufotora ahantu hafite ibintu by’abantu, nk’ahantu hagaragara abantu n’inyubako (urugero: abashumba n’ibyatsi, insengero za kera n’amashyamba), ni byiza gukoresha uburyo busanzwelenzi ya varifocalIbi bizafasha kwirinda kugoreka abantu cyangwa inyubako mu buryo budasanzwe bitewe n'uko ibintu bireba.
5.Ishusho igaragara ahantu hafunganye
Mu gihe ufata amashusho y’ibice bihanamye mu buryo bufunze nko mu mikokwe cyangwa mu nzira z’amashyamba, gukoresha lenzi ifite imiterere yagutse cyane ni byiza, kuko igufasha gufata ishusho yuzuye y’ibidukikije uri ahantu haciriritse.
6.Amafoto n'amafoto y'ingendo za buri munsi
Kugira ngo hafatwe amashusho y'urugendo rwa buri munsi, lenti igomba kuba ishobora kwimurwa, ikagira imiterere yoroshye, kandi ikabasha guhindura vuba amashusho (nk'indabyo zo imbere n'ibyatsi kugeza ku misozi yo hagati), ifite uburebure bunini kugira ngo idahinduka kenshi. Lenti isanzwe ya varifocal irakwiriye kuri iyi ntego.

7.Gurasa mu gihe cy'urumuri ruto
Mu gihe ufata amashusho mu bihe by'urumuri ruto, nko mu gihe cy'izuba rirashe, izuba rirenze, cyangwa mu minsi y'ibicu, ni byiza guhitamo lensi nini ifite umwanya munini, nka lensi ya 16-35mm cyangwa 24-70mm ifite umwanya uhoraho wa f/2.8. Ibi bituma shutter yihuta kandi bigabanya uburibwe bw'amashusho. Ku rundi ruhande, mu bihe by'urumuri rwinshi, nko mu gihe cya saa sita, ushobora gukoresha lensi ya varifocal ifite umwanya muto (nka f/4 cyangwa f/5.6) kugira ngo ibintu byegereye n'ibya kure bikomeze kwitabwaho.
Muri make, mu gihe ufotora ahantu nyaburanga, ugomba gutekereza ku bintu nk'intera y'ikintu, imiterere y'ahantu nyaburanga, n'imiterere y'urumuri kugira ngo uhitemo aho hakwiyelenzi ya varifocal, bityo bikarushaho kugaragaza imbaraga z'amafoto yawe yo mu bidukikije.
Ibitekerezo bya nyuma:
Niba ushishikajwe no kugura ubwoko butandukanye bw'amalenzi yo kugenzura, gupima, indege zitagira abapilote, inzu igezweho, cyangwa ikindi kintu icyo ari cyo cyose, dufite ibyo ukeneye. Twandikire uyu munsi kugira ngo umenye byinshi ku malenzi yacu n'ibindi bikoresho.
