Ifoto enkulu kakhuluiilensi, ingakumbi ezo zinobude obuyi-300mm nangaphezulu, zizixhobo ezibalulekileyo ekufoteni iintaka, ezikuvumela ukuba uthwebule imifanekiso ecacileyo neneenkcukacha ngaphandle kokuphazamisa indlela eziziphatha ngayo, njengesiphumo sokusebenzisa iteleskopu enkulu.
Kule nqaku, siza kufunda malunga nokusetyenziswa kwee-super telephoto lens ekufoteni iintaka.
1.Ubuchule bokuthwebula obude
Ngenxa yokuba iintaka zihlala kwiindawo ezikude nabantu, iilensi ze-super-telephoto zibonelela ngobukhulu obuphezulu kakhulu, nto leyo evumela abafoti ukuba bathathe imifanekiso eneenkcukacha zeentaka ezikude ngaphandle kokuphazamisa indlela eziziphatha ngayo. Olu phawu lubaluleke kakhulu xa uthatha imifanekiso yeentaka ezingaqhelekanga.
Umzekelo, kwiindawo zokugcina indalo okanye endle, ukusebenzisa ilensi ye-ultra-telephoto kukuvumela ukuba ungayinaki imiqobo efana nemithi nomhlaba kwaye uthwebule ngokuthe ngqo iindlwane zeentaka ezikwimithi okanye imihlambi yeentaka ezifudukayo emanzini. Usebenzisa ilensi engama-600mm, ungadubula izinto ezimalunga nama-90cm kumgama weemitha ezili-100, okwenza kube lula ukuthwebula umzuzu wee-hummingbirds eziphaphazela amaphiko azo okanye iinkozi zizingela.

2.Ulawulo lokucinezelwa kwendawo kunye nokwakhiwa kwayo
Ifoto enkulu kakhuluiilensizibonelela ngesiphumo esinamandla sokucinezela imbonakalo, zisondeza iintaka ezikude ngasemva, zizenze zibonakale ngokucacileyo kwifreyimu. Oku kwenza imvelaphi ingabonakali, kugqamise umxholo, kudala umbono onamandla wobunzulu bokubona.
Olu phawu lweelensi ze-super telephoto luvumela abafoti ukuba bagxile kwiinkcukacha ezithile zeentaka, ezinje ngokuthungwa kweentsiba okanye ukuhamba komlomo, okanye benze iingoma ezinobuchule.
Umzekelo, xa ufota ikreyini enesithsaba esibomvu emi kwindawo emanzi, ukuphuma kwelanga kunye namafu angasemva anokudityaniswa nomntu ochaphazelekayo ngelensi, nto leyo ephucula ibali lomfanekiso.
3.Ukugxila ngokukhawuleza kunye nokudubula kwangoko
Iintaka zihlala zihamba ngokukhawuleza kakhulu, ngoko ke ukufota iintaka kufuna impendulo ekhawulezileyo, ukugxila ngokukhawuleza kunye nokudubula ngokukhawuleza zezona mfuno ziphambili. Iilensi ze-Super telephoto zihlala zixhotyiswe ngenkqubo yokugxila ekhawulezayo, enokugqiba ukugxila ngexesha elifutshane kwaye ibambe amaxesha atshintshayo eentaka.
Umzekelo, xa i-super-telephoto attachment isetyenziswa kunye nelensi ye-F4.5 aperture, inika ukusebenza okuhle kakhulu nakwiimeko ezikhanyayo; xa uthatha iifoto zeeswifts ezizingela phantsi, inokugxila kwimizuzwana eyi-0.5 kuphela, ibambe ngokukhawuleza amandla omzuzwana.

4.Isisombululo esiphezulu kunye nokunikezelwa okuneenkcukacha
Ifoto enkulu kakhuluilensiAyikwazi nje ukudubula iintaka zikude, kodwa ikwakwazi nokuthatha imifanekiso yeentaka ezikufutshane ngokulungelelanisa ubude befocal. Olu buchule luvumela abafoti ukuba bathathe iinkcukacha ezifana nobume beentsiba zentaka kunye nembonakalo yobuso, nto leyo ephucula ukubonakala kwemifanekiso yazo.
Umzekelo, xa ufota ipikoko isasaza iintsiba zayo ngelensi ye-super-telephoto, ubume obunamaxolo beentsiba zayo bunokubuyiselwa ngokucacileyo. Xa idibene ne-teleconverter (efana ne-1.4x okanye i-2x), ilensi ye-600mm inokufikelela ubude obulinganayo be-840mm (1.4x) okanye i-1200mm (2x), ifikelela kwisiphumo "se-telescopic microscopic", esifanelekileyo ekubambeni isakhiwo se-microscopic sezinto zokuzalela iintaka (ezifana neziqu zengca kunye neentsiba).
5.Ukuziqhelanisa neendawo ezintsonkothileyo
Ilensi ye-super telephoto iguquguquka kakhulu kwiindawo ezahlukeneyo kwaye ifanelekile ukusetyenziswa kwiimeko ezahlukeneyo zokukhanya ezifana nokukhanya kwelanga okunamandla okanye iintsuku ezinamafu.
Umzekelo, kwiindawo ezikhanyayo kancinci, iilensi ze-super telephoto zihlala zifuna useto lwe-ISO ephezulu okanye i-flash ukuze zithwebule izilwanyana zasendle kunye nemidlalo. Xa kufotwa iintaka kwiindawo ezimanzi okanye emahlathini, abafoti banokukhetha ukusebenzisa ilensi ye-super telephoto ene-tripod okanye ukuzinzisa umfanekiso emzimbeni ukuqinisekisa ukuba iifoto zizinzile.

6.Izicelo ezikhethekileyo kunye neendlela ezahlukeneyo
Ifoto enkulu kakhuluiilensiingasetyenziselwa ukudala iimbono ezikhethekileyo kunye nokubonakala, kungekuphela nje ekuthatheni imifanekiso yeentaka emzimbeni wonke kodwa nasekuthatheni imifanekiso ekufutshane.
Umzekelo, ngokutshintsha i-engile yokudubula kunye nobude be-focal, okanye ngokusebenzisa iteknoloji yokulawula kude, abafoti banokufota indlela iintaka eziziphatha ngayo okanye izinto ezikufutshane besuka kwiindawo ezifihlakeleyo, befota indlela eguquguqukayo yeentaka ezibhabhayo okanye ubuhle obungashukumiyo beentaka eziphumleyo. Xa ufota iingwenya kwiindawo ezifuywayo zaseAfrika, ilensi engama-600mm ivumela ukubanjwa kweengwenya ngaphakathi kwisithuthi esifihliweyo. Ilensi engama-100-400mm ivumela ukubanjwa kwamehlo eentaka, iintsiba, kunye nezinye iinkcukacha.
Iingcinga Zokugqibela:
Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
