Yiqiniso, amanye ala ma-lens ahlukahlukene futhi angasetshenziswa ezimweni ezihlukahlukene. Qhubeka ufunda ukuze uthole okungcono kakhulu ngezidingo zakho.
Leli lens compact iphelele ekuhambeni kwezithombe kanye nabaqalayo abafaka nje izinzwani zabo zibe yi-EOS prime lenses. Ubude obude buyi-50mm, ubukhulu obuhle bokuveza isithombe nokuthatha izithombe, ngenkathi ukuphakama okuphezulu kwe-f / 1.8 nomjikelezo we-7-blade umsebenzi wokuklama kahle kakhulu ngokudubula ebusuku.
Kwesinye indawo ku-lens, imoto ehambayo ithuthuka ngenkathi i-Movie Servo AF eqhubekayo isekela ama-movie noma ama-movie ngokuhlelekile. Insimbi enamandla enyakazayo ihambisana kahle nekhamera ye-EOS iphinde imele ikhwalithi enkulu yokwakha i-nicer nge-barrel esheshayo kunezingeniso zangaphakathi ezingenayo.
Thola ukuvala okwedlulele kwesenzo ngaleli lensi yokusondeza ye-ultra-wide ye-10-18mm. Uhlelo lwezemidlalo luhlelo oluyisihlanu lwe-zoom optical ehlanganisa ama-optical finesse nokusebenza okunamandla, le lensi ehlanganisiwe nephathekayo isebenza kahle ngekhamera ye-Canon EOS.
Isistimu yokusondeza i-optical ihlanganisa isici esikhulu se-diameter, isici se-UD lens, isici se-lens aspherical, ne-lens coating eveza izithombe eziphezulu zokulungiswa ngaphandle kwe-glare noma ukuphambene. Phakathi naleso sikhathi, ukuvuleka kwamalenta ayisikhombisa kuqinisekisa ukufiphaza okuhle kwesizinda nge f / 4.5-5.6. Ikhamera idlula ebukhali obunqenqemeni, ephelele kuma-portraits noma noma yikuphi ukudubula okubanzi. Ukugxila okuthulile kanye nokushayela kwe-STM kwenza lokhu kube lensi enkulu yokubukwa kwama-movie.
Uma ufuna i-lens elula futhi ehlanganisiwe ukuphonsa ngezimoto zakho zokuhamba, le lensi encane ye-24mm yindlela ephelele. I-lens encane kunazo zonke emgqeni we-EF-S, yenzelwe ukunciphisa inqwaba ngenkathi ibanzi ngokwanele ukuthatha indawo. Unamakhono amakhulu okudubula ama-shots eduze-up, futhi ngokulinganisa okulingana no-35mm we-38mm, ingakwazi ukusingatha ama-shots ahlukahlukene ngaphandle kokuphefumula nokuvutha. I-f / 2.8 STM ekuvuleni kwesikhala esiyisikhombisa esinikeza imininingwane engaphandle kwe-focus nokulandelela okubushelelezi, nakuba abanye abasebenzisi bephawula ukuthi akuthuli ngokwanele ngezinhloso zevidiyo. Uma kungenjalo, ukulungiswa kokugxila kwesikhombisi sesikhathi esigcwele kwimodi ye-One Shot AF kwenza lokhu kube okukhethwa kukho okuzenzekelayo kubathwebuli bezithombe ekuhambeni.
I-design entsha ye-optical kule lensi yokusondeza evamile ephezulu isetha ukuxhuma okukhulu ekukhanyeni komzimba nokuqiniswa kwesithombe. Ukugqama kwendawo yokuthuthukisa kungumphumela wokubunjwa okusha kwe-optical kwezakhi ezingu-17 emaqenjini angu-12, ezinezingqimba ezine-aspherical ezibunjiwe ngilazi. Lesi sinyathelo sinciphisa ukuphazamiseka futhi sinikeza imiphumela engcono kakhulu enqenqemeni kunezinguquko zangaphambilini zalesi lensi.
Leli lens kunoma ubani onesidingo se-lens yokusondeza enesimo esivumelana kakhulu ne-open f / 4-blade 10-circular open that reduces flare, ghosting and reflections. Isendlalelo esincane esiphakamisayo esithombeni landa kakhulu kwandisa umbono ohlanzekile futhi unciphisa isikhathi osidinga ukuyisebenzisa ukuhlela izithombe. Ukungafani nokuqina kwalokhu lens zoom kusenza kube umngane ophelele usuku olugcwele lokudubula, kungakhathaliseki ukuthi kukhona emncintiswaneni wezemidlalo, umshado noma cishe noma yini enye.
Le lens eyengeziwe-zoom ifakwe ubuchwepheshe be-NANO USMM ukukusiza ukuthi ugxile ekutheni uthathe umzuzu oqondile wesithombe esiphelele, ngisho nalapho uqeda izihloko ezikude. Ibuye isebenze nge-ultra-quiet, ikuvumela ukuthi uthathe ividiyo ngaphandle komsindo wokuvala ophazamisa umkhiqizo wokugcina. Esinye isici esihle salolu lensi ye-EF 70-300mm ukubonisa ulwazi lensiza eliseyunithi. Nge-shazi ungakwazi ukunquma ibanga lokugxila, ukujula kwensimu nobude obungama-35 mm obulinganayo obude.
I-lens ihlanganisa amaqembu angu-12 anezici ezingu-17 ezigxile ekusizeni ukuchithwa kwe-chromatic, ukunciphisa ukufiphaza nokugcina izithombe ezigqamile ezimibalabala kulo lonke ukudubula. Uhlaka lwesishiyagalolunye lwesigxobo esinezixhumi eziningana f / 4-5.6 luveza i-bokeh ebushelelezi enesizinda esihle futhi i-autofocus iyashesha. Le nguqulo elula, entsha, futhi engabizi kakhulu ye-Lon "L" yamakhansela we-Canon futhi izokusiza ukuthi uthathe izithombe ezinhle.
Thola ama-landscapes amahle ngokucacile nokuxazulula amandla we-EF 35mm f / 1.4L II USM. Leli lens elisha lingumngane ophezulu ophelile ophethe ubude obugxile obuyi-35mm kuya kusizukulwane esisha seKhanon eliphezulu-resolution SLR kamera. Izingxenye ezintsha ze-BR ze-optics ze-Canon ziholela ekunciphiseni okuncane kwe-chromatic ngenkathi ukuvuleka okuphezulu kwe-f / 1.4 kuthatha izithombe ezimangalisa ezimweni eziphansi. I-lens evulekile yokuhlinzeka inikeza imininingwane ecacile ebukhali ekudaleni izilungiselelo zangaphandle kanye nezindawo ngenkathi igcina umbala omuhle nokuphambene.
Leli lens yokugcina lensiza ye-70-200mm elide linomshini wokugxila wangaphakathi kanye ne-ring-type monitor ultra-sonic yokuzenzekelayo ngokuzenzekelayo. I-l-professional L-uchungechunge lwe-L-uchungechunge lwe-telephoto lensiza lwenziwa ukwenza isenzo esikude. Ukwakhiwa kwamalensi kwenziwa ngezingxenye ezingu-16 emaqenjini angu-13 ahlanganisa i-Fluorite element enezici ezimbili ze-UD-glass ezingahlukanisa izingxenye ezithile zesibhamu ukuze zithole idrama kakhulu nemininingwane. I-lens yakhiwa ngezinto eziphezulu zekhwalithi futhi ine-ergonomic emnandi ngenkathi izwa ilanga lensiza enkulu kangaka ye-telephoto.
