Thatha iipilisi eziphambili ngokubhekiselele kulezi lensi ezinkulu
Ikhamera ye-DSLR yekhwalithi ifuna i-lens efanelekileyo ukuba ithathe umfanekiso opheleleyo. Ukuba unayo ikhamera ye-EOS ye-Canon ye-Canon unayo i-lens eninzi ekhoyo. Ingaba ungumtyikitya ofunayo i-telephoto lens okanye uhlobo lweefoto-photographer olufuna isisombululo esiphantsi sokudubula okuphantsi, i-Canon inezinto ezininzi ezikhoyo. Iilensi ziyahluka kwixabiso kunye nesicelo, ke qiniseka ukuba ucinga malunga nesicelo sakho ngaphambi kokuba ukhethe! Ewe, ezinye zee-lens zichanekile kwaye zingasetyenziswa kwiimeko ezahlukeneyo. Qhubeka ufunda ukufumana eyona nto imfuno zakho.
Le lenti yecompact igqibelele ekuhambeni kweefoto kunye nabaqalayo ababethela izandla zabo zibe yi-EOS prime lenses. Ubude obude buyi-50mm, ubukhulu obuhle bokubonakalisa iifoto kunye nokuthatha iifoto zento, ngelixa ukugqithiswa okukhulu kwe f / 1.8 kunye neesetyhula umsebenzi wezakhiwo ezi-7 ngokukhawuleza ukuthunjwa ebusuku.
Kwesinye indawo kwi-lens, umqhubi ohambayo uhamba ngokuthula ngenkathi i-Movie Servo AF eqhubekayo inceda ukubetha i-movie okanye iifilimu kwisakhelo esipheleleyo. Intaba yentsimbi enqabileyo ihambelana kakuhle kwiikhamera ze-EOS kwaye ibonisa ikhwalithi enkulu yokwakha i-nicer nge-barreler barrel ngaphezu kokungeniswa kwamanqanaba angaphambili.
Fumana ngokusondeleyo kwezenzo ngelo lensi ye-zoom ye-10-18mm ephezulu. Iimidlalo zenkqubo ye-zoom ye-five optical zoom edibanisa i-finesse ye-optical kunye nokusebenza ngokugqithiseleyo, ilensi ye-compact ne-portable isebenza kakhulu ngeekhamera ze-Canon EOS.
Inkqubo yokumisa i-optical iquka into ebanzi, i-UD lens element, i-lens element, kunye neengubo zensiza ezivelisa imifanekiso enqabileyo ngaphandle kokugqithisa okanye ukungafani. Okwangoku, isithuba esisixhenxe se-blade siqinisekisa isiqhelo esihle semvelaphi kunye ne-f / 4.5-5.6. Ikhamera ihamba phambili ekugqibeleni ngokukhawuleza, epheleleyo kwimifanekiso okanye nawaphi na amaqhosha amaninzi. Ugxininiso oluthe cwaka kunye nokuqhutshwa kwe-STM kwenza le nto ibe yilensi enkulu yeefilimu zokudubula.
Ukuba ukhangele i-lens elula kunye ne-compact lens ukuze uphonse ngegesi lakho lokuhamba, le lensi encinane ye-24mm iyona ndlela efanelekileyo. I-lens encinci kumgca we-EF-S, yenzelwe ukunciphisa ubuninzi ngelixa libanzi ngokwaneleyo ukuthabatha indawo. Unamandla amakhulu okudubula amashishini afanelekileyo okusondeleyo, kunye nobude obulingana ne-35mm eyi-38mm, inokusingatha iintlobo ezahlukeneyo zamashishini ngaphandle kokuphosa nokukhupha. I-f / 2.8 i-STM kwisibonda sesetyhula esisixhenxe isinika inkcazelo engaphezulu kwe-focus kunye nokulandelela ngokukhawuleza, nangona abanye abasebenzisi bayiqaphela ukuba ayithethi ngokwaneleyo ngenjongo yevidiyo. Ngaphandle koko, ukulungiswa kwenkcazelo yexesha elizeleyo kwimodi ye-One Shot AF yenza okukhethwa kukho okuchanekileyo kubafaki-zithombe ekuhambeni.
Yonke into eyenziwa ngokutsha kwintsebenzo yolu lwakhiwo oluphezulu olusebenzayo luzisa ukugquma okukhulu kwi-peripheral brightness and image stabilization. Ukuphuculwa kwendlela yokuphuculwa kwimizila kubangelwa ukubunjwa kwe-optical entsha yezinto ezili-17 kumaqela angama-12, ezinezilwanyana ezine-glass-as molded lenses. Eli nyathelo liyanciphisa ukuphazamiseka kwaye linikeza iziphumo ezingaphezulu kweendlela eziphambili kune-iteration yangaphambili yale lensi.
Le lensi yeyomntu onesidingo sokwakheka kwe-zoom lens egxininisekayo kunye ne-f / 4 e-blade ye-blade ye-blade ye-blade eyenza ukunciphisa i-flare, ukuphosa kunye nokubonakalisa. Isalathiso esiphantsi sokurhoxisa kwi-lens yandisa ngakumbi imbonakalo ecocekileyo kwaye imide ixesha omele usebenzise ngayo ukuhlela iifoto. Ukuchaneka kunye nokuhlala kwale lensi yokusondeza kwenza kube ngumlingane ogqibeleleyo usuku olupheleleyo lokudubula, nokuba ngaba kumqhubi wezemidlalo, umtshato okanye malunga nantoni na enye into.
Le lens eyongezelelweyo-zoom ixhotyiswe ngeteknoloji ye-NANO USM ukukunceda ugxininise ekuthatheni umzuzu ochanekileyo womfanekiso ogqwebileyo, nangona xa uhluma izifundo ezikude. Kwakhona isebenze ngokukhawuleza, ukuvumela ukuba uthathe ividiyo ngaphandle kwengxolo yokuvala ifuthe echaphazela imveliso yokugqibela. Enye into ebalulekileyo yolu lensisi ye-EF 70-300mm yinkcazo yolwazi lensi efumaneka kwiyunithi. Xa ujonga ungagqiba umgama, ugxininiso lwensimu kunye nobude obulinganayo be-35 mm.
I-lens iquka amaqela angama-12 aneenkalo ezili-17 ezijolise ekuncediseni ukuchithwa kwe-chromatic, ukunciphisa ukugquma kunye nokugcina imifanekiso eyahlukileyo ebonakalayo phakathi kokudubula. I-blade yesithoba yesango kunye nenani eliphezulu le f / 4-5.6 livelisa i-bokeh ephosakeleyo eneemvelaphi ezintle kwaye i-autofocus iyakhawuleza. Le yinto elula, entsha, kunye nexabiso elincinci le-Lon "L" ye-Canon kwaye iya kukunceda ukuba uthathe imifanekiso emihle.
Fumana amabala omhle ngokucacileyo kunye nokuxazulula amandla e-EF 35mm f / 1.4L II USM. I-lens entsha ihamba kunye nomgca ophezulu ophezulu we-35mm ukuya kwisizukulwana esandul 'ukutsha kweekhamera ze-Canon eziphambili ze-SLR. Izinto ezintsha ze-BR ze-optics zenza i-aberration encinci ye-chromatic ngelixa isithuba esiphezulu se-blade se-f / 1.4 sithatha imifanekiso emangalisayo kwiimeko eziphantsi. I-lens ephantsi yokuvula ibonelela ngokucacileyo iinkcukacha ezicwangcisiweyo kwiinkcukacha zangaphandle kunye neendawo xa ulondoloza umbala omhle kunye nokuphambene.
Le lens ende ye-telephoto ye-zoom ye-70-200mm ine-system yokugxininisa ngaphakathi kunye ne-ring-type son-sonic yokujonga ngokukhawuleza ngokuzenzekelayo. I-l-series ye-professional-quality-L-series ye-telephoto zoom zoom isetyenziselwa ukuthatha inyathelo elide. Ukwakhiwa kwelensi kwenziwe ngamaqela angama-16 kumaqela ayi-13 adibanisa into yeFluorite enezinto ezimbini ze-glass-glass ezingakwazi ukuhlukanisa iindawo ezithile zefowuni ukuze zenze umdlalo. I-lens yakhiwe ngezinto eziphezulu zeemveliso kwaye ine-ergonomics emnandi ngelixa ivakalelwa yilelo lense enkulu ye-telephoto.
