I-China Uhlelo lweKhamera Kits nge-8 Camera Abahlinzeki
Ukuhlaziywa okuqondayo kwamakhamera anencazelo ephezulu yencazelo ephezulu kuhloselwe ikakhulukazi ukuhlaziya okunembile, ukwahlulela ukwehluleka okujwayelekile kwekhamera okufana nesikrini esimnyama, ukufiphala, ukuphuma kwe-PTZ, nokuphazamiseka kwesiginali, nokuphazamiseka kwesithombe wanyamalala, njll.
I-FUVision 3 million izigidi eziyizigidi ze-WiFi Security Security Camera Ukubhekwa Kwekhamera Yezindlela ezimbili.
Isibani sombani
Iphaneli yesibani ihlukaniswe izibani ezijwayelekile ze-infrared (Dingyuan kanye neGuanglei) kanye namaLambu ahluzekile. Ikhamera yama-Aray nayo ihlukaniswe nge-1W, 2W no-3W. Ngakho-ke, lapho ukhetha izibani ezingezinhluthulelo, uma kuyisibani esivamile se-infrared, zama ukukhetha amalambu e-dingyuan nama-3W array. Njengoba ukubonakala kwamalambu angezinhlaka kungabonakali ngokuvamile, amanye amakhamera e-cottage agcwele amakhamera weGuanglei nama-1W array agcwaliswa ngamakhamera we-3W array. Ngakho-ke, zama ukukhetha uhlobo olukhulu lapho ukhetha amakhamera.
Ukuhlobisa okuphezulu
Inani langempela lesilinganiso esiphezulu ukwenza ngcono ukuthathwa kokukhanya ngaphansi kwezimo eziphansi zokukhanya, ukuze kufinyelelwe inhlanganisela yokuvezwa okuhle kakhulu. Ngokuvamile, amandla okubona ngeso lengqondo ilensi ayidingeki ngokudubula komhlaba. Ngaphezu kwalokho, i-lens caliber ayidingeki ekudubuleni komhlaba ngaphandle kwezindawo ezimnyama ikakhulukazi. Kodwa-ke, lapho ilensi yokusondeza ye-70-200mm ifakwe ilensi yokusondeza oku-2 ukuze enze isigaba se-Telephoto ukuba sibe ngu-400mm futhi kungcono ukukhetha ilensi ngokuhlekisa ngobukhulu be-F2.8. Ukuhlobisa okukhulu kuyasiza ekugxiliseni okunembile ezimweni zobumnyama. Lapho udubula abantu ngelensi enkulu ye-lens, ngisho nasezindaweni lapho ukukhanya kubuthakathaka khona, i-handset ingasebenzisa nokukhanya kwemvelo ukudubula. Ngaphezu kwalokho, ilensi enobuhlakani obukhulu ingaletha isivinini esikhulu sokuvala, ngakho-ke izithombe zezemidlalo zidinga nelensi enkulu ye-apertire.
Esinye isizathu sokudinga ukuthi i-lens actorture ibe nkulu ukukwazi ukubona ngeso lengqondo ingemuva ngokukhululekile futhi uqinisekise ikhwalithi yokubuka ngamehlo. Lapho ukuthambekela kwelensi enobuhlakani obuphezulu be-F1.4 kuncishisiwe ku-F2, zombili ikhwalithi yokucabanga kanye nekhwalithi ye-blurring yesizinda kungcono kunaleyo ye-lens enesilinganiso esiphezulu se-F2. Ngakho-ke, kubaluleke kakhulu ukunciphisa ukuthambekela kwelensi enkulu yokuhlasela ngesitofu esisodwa. Noma yimuphi umthwebuli wezithombe kufanele abe kahle ekusebenziseni ilensi.
ubude obugxile
Into yokuqala okufanele unake lapho ukhetha ilensi ubude bamalensi. Eqinisweni, ubude obugxile kumbono. Ubude obuhlukile bokugxila nemibono yehlukile. Ngaphezu kwalokho, abasebenzisi kufanele bacace ukuthi yini inhloso enkulu yamalensi wokuthenga? Ingabe ukubonwa noma abantu. Njengoba sonke sazi, kungcono ukusebenzisa ilensi ebanzi engela lapho kudutshulwa izindawo zomhlaba, kanye nelensi ye-telescopic lapho kudubula abantu. Ngakho-ke, kufanele uqale uthathe isinqumo sobude obugxile kumalensi ofuna ukuthenga ngokuya ngezithombe.
Izigaba ezinhle kakhulu zokugxila zokudubula indawo yokudubula ziyingxenye yokugxila ebanzi ye-Angle eyi-24 kanye ne-200 MM telescopic isigaba (zombili zisuselwa ekucacisweni okungu-35 mm, okufanayo ngezansi). Lapho ingxenye enkulu yokugxila ye-angle ye-lens evamile ivela kusuka ku-28mm kuya ku-24mm, i-angle yokubuka iba nkulu, futhi uhla lwendawo olungagcinwa lunwetshwe kakhulu. Ngokuvamile, ukugcotshwa okuphezulu kwamalensi akudingeki ekudubuleni komhlaba. Uma udubula imindeni, ubude obubanzi obubanzi be-angle buka-24mm ngokwanele uma ukhetha ilensi yokusondeza. Ngokuqondene nengxenye ye-Telephoto, kumele okungenani ibe ngu-200mm. Uma isigaba se-Telephoto singama-300mm noma i-400mm, sihle kakhulu, futhi izinga lenkululeko lizothuthukiswa kakhulu. Ingxenye ye-Telection Forge of Zoom Lens yendabuko ingu-300 mm, okuyi-450 mm ye-Digital SLR. Ubude obugxile kulokwenziwe yizikhathi eziyi-1.5, ezenza kube mnandi ukusebenzisa. Leli inani ledijithali SLR. Ingxenye ebanzi e-Angle Engela ye-Ultra ekhethekile ye-Ultra Wide-Angle Lens ekhiqizwa ngokuvamile ingu-12mm, lilingana ne-18mm yama-35mm, elicishe libe yizikhathi ezingama-35mm ezi-35mm, ngaleyo ndlela zikhulise kakhulu uhla lwesobunxele nakwesokudla lwe indawo enhle.
Ubude obuhle kakhulu bokudubula abantu ngu-85mm. Ngokwesilinganiso esijwayelekile esingu-35mm, ubude obugxile ku-85mm busetshenziswa ngokuyisisekelo njengezinga lezinhlamvu zokudubula. I-Portrait ethathwe yisigaba esigxile esingu-85mm ngokuyisisekelo iseduze komphumela wesithombe othathwe yikhamera yohlaka oluphakathi. Akulungele kuphela ibanga, kepha futhi ubuso bomuntu bubukeka bungokwemvelo kakhulu. Ibanga phakathi kwekhamera nomuntu othathwe izithombe angagcinwa ngokuyisisekelo ebangeni elijwayelekile lokukhuluma. Ubude obugxile be-85mm bungafiphalisa ngempumelelo ngemuva nangezinhlamvu ezivelele. Ukuze uthole umphumela omuhle wokubuka izithombe, ilensi enesici esikhulu kunazo zonke kufanele ikhethwe. Ubude obugxile be-85mm bungama-135mm kwi-Digital SLR. Yize umuzwa webanga lokudutshulwa abuthakathaka kancane, ngokuyisisekelo kulungile, ngakho-ke ubude obugxile kumuntu kufanele okungenani babe ngama-85mm.
Ilensi ye-macro eyi-100mm yanele ngendabuko SLR ukudubula izimbali. Ilensi ye-macro macro ingasetshenziselwa izithombe ezilinganayo zokulinganisa, ezingenza izimbali zizinkulu kakhulu. Kodwa-ke, lapho uthatha izithombe ezilinganayo zokubumba noma ukuvezwa kwezithombe ezilinganayo, ngenxa yokujula kwesigameko eside sokugxila, kulula ukunyakaziswa, ngakho-ke izindlela zokushushuluza i-anti kufanele zibhekwe lapho zithatha izithombe. Kusuka kuleli phuzu lokubukwa, ama-lens angama-50mm macro kulula ukulisebenzisa ku-Digital SLR.
