Uhlolojikelele kanye nezici ze-Infrared Zoom Lens

I-infrared zoom lens iyilensi yekhamera engashintsha ubude bokugxila phakathi kwebanga elithile ukuze ithole ama-engeli ahlukene okubuka abanzi nawumngcingo, izithombe zosayizi abahlukahlukene, nobubanzi bezigcawu abahlukahlukene.

Ilensi yokusondeza ye-infrared ingashintsha ibanga lokudubula ngokushintsha ubude bokugxila ngaphandle kokushintsha ibanga lokudubula.Ngakho-ke, i-zoom lens ye-infrared ivumela kakhulu ukwakheka kwesithombe.

Njengoba ilensi yokusondeza ye-infrared ingaphinda kabili njengamalensi agxilile amaningi, inani lezinto zokusebenza zezithombe okufanele ziphathwe lapho uhamba liyancishiswa, futhi isikhathi sokushintsha amalensi siyagcinwa.

Amalensi okusondeza kwe-infrared ahlukaniswe amalensi okusondeza nge-infrared anemotho kanye namalensi e-infrared agxile kumanuwali.

I-lens ye-infrared

Amalensi okusondeza e-IR athambekele kakhulu ekukhanyeni kunamanye amalensi, ngakho-ke ihood efanelekile yelensi ibalulekile.Kwesinye isikhathi, ukufiphala okubangelwa i-hood akubonakali kusikrini sokubuka sekhamera ye-SLR, kodwa kungabonakala kufilimu.Lokhu kubonakala kakhulu lapho ukudubula ngezimbobo ezincane.Amalensi okusondeza kwe-infrared ngokuvamile asebenzisa i-lens hood.

Amanye ama-hood asebenza kahle ekugcineni kwe-telephoto, kodwa uma usondezwe ekupheleni okufushane, isithombe sizoba ne-vignetting ebangelwa ukuvaleka, okungenakubonwa esikrinini sesitholi sokubuka.

Amanye amalensi okusondeza e-IR adinga ukushintsha izindandatho zokulawula ezimbili ezihlukene, eyodwa ibe eyokugxila neyodwa ukuze kugxilwe kuyo.Inzuzo yalesi sakhiwo sesakhiwo ukuthi uma ukugxila sekufinyelelwe, indawo okugxilwe kuyo ngeke ishintshwe ngephutha ngokulungisa ukugxila.

Amanye amalensi okusondeza e-SWIR adinga kuphela ukuhambisa indandatho yokulawula, aguqule okugxilwe kuwo, futhi ushelele emuva naphambili ukuze ushintshe ubude bokugxilile.

Le lensi yokusondeza “endandatho eyodwa” ngokuvamile iyashesha futhi kulula ukuyiphatha, kodwa futhi ivamise ukubiza kakhulu.Kumele kuqashelwe ukuthi lapho ushintsha ubude bokugxila, ungalahlekelwa ukugxila okucacile kwelensi yokusondeza ye-infrared.

Sebenzisa izisekelo ngendlela efanele.Uma usebenzisa ubude bokugxila obungu-300NM noma ngaphezulu, ilensi kufanele imiswe ku-tripod noma omunye ubakaki ukuze kuqinisekiswe ukuzinza ngesikhathi sokudubula.
