Kunzwisisa Kusiyanisa Pakati Pakazara Mufambiro uye Sensor Crop
Chimwe chezvinhu zvinonyanya kuvhiringidza kana kuvandudzirwa ku DSLR kunzwisisa kusiyana pakati pechigadziro chakakwana uye chikwata chekamera makamera. Paunenge uchishandisa kakomera kamera, izvi hazvizovi chinhu chaunoda kutarisana nayo, sezvakavakwa mumarangariro zvakagadzirirwa kuita kuti kusiyana kusinganzwisisike. Asi paunotanga kutarisa pakutenga DSLR, kunzwisisa chimiro chakakwana kana kuenzaniswa kwemajeri senjere kuchakubatsira zvikuru.
Full Frame
Kudzoka mumazuva ekufambisa mafirimu, pakanga pane uwandu humwe chete hwemagetsi mune 35mm photography: 24mm x 36mm. Saka kana vanhu vachitaura nezve "fomu yakazara" makamera mumifananidzo yekudhijita, ivo vari kukurukura usayizi hwema sensor 24x36.
Zvinosuruvarisa, zvizere zvikamu zvemakamera zvinowanzouya nekakawanda chetengo tag. Iko inodhura yakazara yakagadzirwa Canon kamera, somuenzaniso, ine zvuru zvemadhora mashoma. Yakazara yakazara makamera makamera anoshandiswa nevevhivi vemifananidzo, avo vanoda zvimwe zvikamu. Mimwe nzira ndeye "cropped frame" makamera, kana kuti "mbeu sensor" makamera. Izvi zvine mutengo wemari unodhura, unoita kuti zviwedzere kunakidza kune avo vanotanga ne DSLRs.
Cropped Frame
Chimiro chakakonzerwa kana chinzwa chakafanana nekutora pakati pechifananidzo nekurasa kunze kwemitsara. Saka zvinonyanya kukosha, iwe unosara une chimiro chakaonda kudarika chinowanzoitika - zvakafanana mumamiriro ehupenyu hwemafupi APS mafirimu. Chaizvoizvo, Canon , Pentax uye Sony inowanzotaurira ma sensor avo vakagadzirwa se "APS-C" kamera. Kungovhiringidza zvinhu zvakadaro, Nikon anoita zvinhu zvakasiyana. Nikon's full frame cameras go under the moniker of "FX," apo cropped frame cameras inozivikanwa se "DX." Pakupedzisira, Olympus nePanasonic / Leica vanoshandisa maitiro akasiyana-siyana akasiyana-siyana anozivikanwa seHurumende yeTatu.
Muchero we sensor inopesana zvishomanana pakati pevakugadziriwo zvakare. Vazhinji vezvirimwa zvekugadzira zvishoma kudarika nhengo yakazara yefaira ne 1.6 chiyero. Zvisinei, chiyero chaNicon chikamu che 1.5 uye Olympus 'chikamu 2.
Lenses
Pano ndipo panopesana kusiyana pakati pechigadziko chakazara uye chakakonzerwa chaizvo. Nekutenga kamera ye DSLR inouya mukana wekutenga yose yakakwana yemarori (yakapa bhajeti yako). Kana iwe uchibva pane firimu kamera yakatarisa, iwe unogona kunge uine kakakura kwema -lens anogadziriswa ari pamusoro. Asi, paunenge uchishandisa kamera yakagadziriswa, iwe unofanirwa kuyeuka kuti urefu hukuru hweizvi lenzi huchashandurwa. Nemuenzaniso, pamwe neKanon makamera, iwe uchada kuwedzera urefu hukuru ne 1.6, sezvataurwa pamusoro apa. Saka, 50mm lens standard ichava 80mm. Izvi zvinogona kubatsira zvikuru kana zvasvika kune telephoto lenses, sezvo iwe uchawana mahmita, asi flip ndeyekuti yakareba-angle lenzi ichava lenzi yakazara.
Vagadziri vauya vane zvigadzirisa dambudziko iri. Kune Canon naNicon, avo vose vanobudisa zvizere fomu makamera, mhinduro yave iri yekubudisa mavara emhando yakagadzirirwa zvakanakira kamera dzemakambani - EF-S yakananga ye Canon uye DX range ye Nikon. Izvi zvinosanganisira yakawanda-angle-lenses iyo, iyo yakakudzwa, ichiri kubvumira kuti maonero marefu. Semuenzaniso, vese vanogadzirisa vanobudisa lens lens rinotanga pa 10mm, nokudaro kupa chaiyo yakareba urefu hwema 16mm, iyo inenge iine yakakura kwazvo-angle lens. Uye aya majekisi akave akagadzirirwawo kuderedza kusvibiswa uye kuisa vignetting pamiganhu yechifananidzo. Ndiyo nyaya yakafanana naivo vadziri vese vari kubudisa chete makambani ekujaira makamera, sezvo lenzi dzavo dzose dzakagadzirirwa kumhanya pamwe chete nemakiromera aya.
Pane Pane Kusiyana Pakati Pemarudzi EmaLensi?
Kune musiyano pakati pe lenzi, kunyanya kana iwe ukatenga mune imwe yeCanon kana yeNikon systems. Uye ava vaviri vanogadzirisa vanopa huwandu hwakawanda kwazvo hwekamera uye lenzi, naizvozvo zviri nyore kuti iwe uchatora mune imwe yei. Kunyange zvazvo lenzi dzemagetsi dzichikwikwidzana zvikuru, unhu hwe optics hahuna kunaka sezvakangoita mafirimu lenzi. Kana iwe uchangotarisa kushandisa kamera yako kuti uwane mapikicha ekutanga, iwe ungasazoona mutsauko. Asi, kana uri kutarisa kuti uone zvakanyanya nezvekupfeka kwako, saka zvakakosha kuti iwe uwane mari mukati mekutanga kwema lenses.
Inofanirawo kuonekwa kuti Canon yeEF-S lenzi haizoshandi zvachose pamakambani akazara makamera. Iyo Nikon DX lenses ichashanda pamagetsi ayo akazara makamera, asi pachava nekurasikirwa kwechisarudzo pakuita kudaro.
Iko Fomu Yakakunakira Iwe?
Chimiro chemakamera chakakwana chinokupa simba rekushandisa lenzi panzvimbo dzavo dzemazuva ose, uye inonyanya kupenya mukukwanisa kwavo kurarama nekupfura paIOs yakakwirira. Kana iwe uchipfura zvakawanda mumasikirwo uye zvishoma, ipapo iwe pasina mubvunzo uchawana izvi zvakakosha. Vaya vanotema masvingo uye mapikicha ekugadzira mapurisa vachadawo kutarisa mazamu akazara ezvigadziriswa sezvo unhu hwemufananidzo uye yakakura-angle angle lens inenge iri mberi.
Pamusana pezvisikwa, mhuka dzesango, uye mitambo inofarira, inzwa yakagadzika ichaita kuti iwedzere kunzwisisa. Iwe unogona kutora mukana wehuwandu hwakawedzerwa hukuru hwakapiwa nemakwikwi akasiyana-siyana uye makamera acho anowanzove nekukurumidza kupfuurira kupfufurwa nekukurumidza. Uye, apo iwe uchatora kuverenga urefu hwemahombekombe, iwe uchachengetedza chinyorwa chekutanga che lens. Saka, kana iwe wakagadziridza 50mm lens iyo inonzi f2.8, zvino ichachengetedza izvi kusvika kunyange kukura kusvika ku 80mm.
Zvose zviri zviviri zvine maitiro avo. Chimiro chemakamera chakakura, chakakura, uye chakanyanya kudhura. Vane zvizhinji zvezvikomborero zvevashandi, asi vanhu vazhinji havadi kunyatsoda zvinhu izvi. Usanyengerwa nemutengesi anokuudza kuti unoda kamera inodhura zvakanyanya. Chero bedzi iwe uine mazano mashomanana akajeka mupfungwa, iwe unofanirwa kunyatsogadziriswa kuita sarudzo yakanaka yezvaunoda.
