Lens yowonera imatha kuthandizira kupanga zithunzi zabwino kwambiri zokhala ndi zowoneka bwino za bokeh, kapena kujambula mitu yakutali momveka bwino komanso molondola.
M'nkhaniyi, tiwona mozama momwe zoom lens ili, zomwe ingachite, komanso nthawi yomwe mungaigwiritse ntchito pojambula zithunzi.
Mu positi iyi tikambirana:
Tanthauzo la Lens ya Zoom
Pojambula, lens ya zoom ndi mtundu wa lens wokhala ndi kutalika kosiyana. Kutha kusintha kutalika kwapakati kumadziwika kuti zooming. Ndi lens yowonera, ojambula amatha kusintha mawonekedwe awo mwachangu komanso mosavuta kuti agwirizane ndi mutu womwe ukujambulidwa posintha kutalika kwake.
Ma lens a zoom amagwiritsa ntchito ma lens amkati opangidwa kuti aziyenda molumikizana wina ndi mnzake kuti akwaniritse makulidwe osiyanasiyana a chithunzi pamtunda wosiyanasiyana kuchokera ku chinthu. Lens yamtundu uliwonse imadziwika ndi mitundu yake - mwachitsanzo, 18-55 mm kapena 70-200 mm - zomwe zikutanthawuza utali wotalikirapo komanso wautali kwambiri womwe mandala angakhazikitsidwe. Nthawi zambiri mukatalikirana ndi phunziro lanu (mwachitsanzo, kuyenda chammbuyo), chithunzi chanu chidzakula; kumbali ina, mukakhala pafupi, idzakhala yaying'ono (mwachitsanzo, kuyenda kutsogolo).
Ma zoom ambiri amakhala ndi magalasi osiyanasiyana a 35mm. Izi zikutanthauza kuti amapereka kusinthasintha kwachilengedwe chifukwa ndi koyenera mtunda wowombera mosiyanasiyana ndikupangitsa kuti ikhale yosunthika kuposa ma lens apamwamba, omwe amakhala ndi utali wokhazikika womwe sungathe kusinthidwa popanda kusintha magalasi kapena kulumikiza zida zakunja monga ma teleconverter. Zooms nthawi zambiri zimapereka kuthwa kwabwinoko kuposa mitundu yayikulu.

Kutsika kwa chiwerengerocho, kumawonekeranso kwakukulu; chiwerengero chapamwamba, chocheperapo. Ma lens a zoom amatha kugawidwa m'magulu atatu osiyanasiyana: makulitsidwe atali-mbali, ma zoom wamba, ndi ma telephoto zoom.
Ma lens otalikirapo amakupatsirani mawonekedwe otambasuka kuposa omwe mungapeze ndi lens yautali wokhazikika kapena lens yanthawi zonse yowonera. Izi ndizisankho zabwino ngati mukufuna kujambula zithunzi zazikulu kapena kufananiza zazikulu zakunja mukuwombera kwanu chifukwa zimaphatikizira zinthu zakutali kuchepetsa kupotoza kwamawonekedwe ndikukuthandizani kuti mujambule chilichonse chomwe chili muzithunzi zanu.
Ma lens owoneka bwino amakhala ndi kutalika kwapakati komwe kumayambira 24 mpaka 70mm pamitundu yambiri. Amapereka kusinthasintha kochulukirapo kuposa magalasi amtali osasunthika chifukwa cha kuthekera kwawo kusintha mwachangu kuchokera pakuwombera kwapakatikati kupita kufupi. Ma lens amtunduwu ndi abwino kuti agwiritsidwe ntchito mosiyanasiyana monga kujambula paulendo, zolemba, zochitika zapanyumba, kujambula zithunzi wamba kapena zithunzi zatsiku ndi tsiku.
Magalasi a Telephoto zoom amakhala ndi utali wotalikirapo kuyambira pafupifupi 70mm kapena kupitilira apo ndikupitilira mpaka mamilimita mazana angapo (kapena kupitilira apo). Magalasi amtunduwu amapambana kwambiri popangitsa kuti zinthu zakutali ziwonekere pafupi powombera malo, kujambula nyama zakuthengo ndi zochitika zamasewera popanda kufunikira zida zochulukirapo ngati ma tripod ndi ma monopods chifukwa zolimbitsa thupi zawo zolimba zomwe zimachepetsa kugwedezeka kwa kamera.
ubwino
Ma lens a Zoom amapereka kusinthasintha kwa ojambula, popeza amapereka mawonekedwe osiyanasiyana komanso kuthekera kofikira ndikujambula zambiri. Ma lens a Zoom ndiabwino kujambula malo komanso kujambula nyama zakuthengo zomwe zimayenera kuyang'aniridwa kuti ziwonetsedwe zakutali. Pali zabwino zina zowonera magalasi omwe tiwona tsopano.
Kusagwirizana
Ma lens a Zoom amapereka kusinthasintha kwa ojambula amitundu yonse, kaya ndi akatswiri odziwa zambiri kapena amangomasuka ndi zida zapamwamba kwambiri. Izi zili choncho chifukwa magalasi owonetsera amatha kusintha kutalika kwa lens - kukulolani kuti musankhe mawonedwe ambiri, kapena telephoto kutengera zomwe zikugwirizana ndi zomwe zikuchitika. Kutha kusinthana pakati pa utali wokhazikika womwe umagwirizana kumawapangitsa kukhala abwino kwa oyamba kumene, omwe angaphunzire kulemba bwino kuwombera kwawo, ndi akatswiri omwe akufuna kupanga zithunzi zabwino kwambiri.
Ma lens a zoom amatsegulanso mwayi wopanga - makamaka ndi kujambula zithunzi. Sikuti amatha kujambula pafupi ndi kuwombera kolimba komwe kungakhale kovuta ngati mukugwiritsa ntchito ma lens apamwamba (ma lens okhazikika), koma muthanso kusinthana pakati pa makulidwe ndi mawonedwe osiyanasiyana panthawi yowombera. Ndipo chifukwa angapo mwa mitundu iyi ya magalasi ali ndi mawonekedwe okhazikika azithunzi, mudzakhala ndi nthawi yosavuta kupeza zithunzi zakuthwa m'malo opepuka osadalira kuthamanga kwa shutter kapena kuthamanga kwa kanema.
Zinthu izi zikaphatikizidwa zimapangitsa kuti magalasi owoneka bwino akhale ofunikira pamitundu yambiri yamitundu - kuchokera pazithunzi za malo komwe kungakhale kothandiza kuyandikira malo akutali kuti muwone bwino popanda kudzikulitsa; kujambula kwamasewera komwe maphunziro angayende mwachangu ndipo amafunikira kulondola kwenikweni; kujambula nyama zakuthengo kuchokera patali; kujambula kwakukulu komwe malo ocheperako amakhala abwino; ndi zina zambiri! Pamapeto pake magalasi owonetsera amapereka kusinthasintha komwe magalasi apamwamba sangapereke - kotero kukhala ndi malingaliro omasuka pazosankha zosiyanasiyana kungapangitse luso lanu kukhala lanjira zatsopano!
