Sida 50D EOS ah, shidma 7D qoreysa gapless microlens ah, waxaase ku fogaaday iyaga iyo madarad oo u dhexeeya waxaa hoos u dambeeyey ku dhacay photons dheeraad ah.

Inkastoo tiro badan oo ah pixels laba Processor Digic 4 iyo gaabnaa sideed-channel, soo saaraha qabsan karo, ugu badnaan xawaare toogashada joogto ah loo siman yahay ilaa 8 / sec.

Tusaale ahaan, button View Live ku yaal dhinaca bidix ee dambe ee Mark 5d ee II shaashadda waxaa lagu wareejiyay xagga Midig viewfinder 7D iyo waxa ay hadda ku hareereysan biiro, taasoo micnaheedu tahay hababka on-screen daawashada iyo video. Waa inuu u dhaqaaqo smart, waayo, haatan ay gacanta ku waa meel uu ka gaaro suulka gacantiisa midig.

meel uu baneeyay View Live, degan laba badhamada kale. Mid ka mid ah calaamadeeyay sidii Q ah, waxaa loo isticmaalaa si dhaqso ah u helaan screen gacanta.

goobaha image

Miisaanku waa nidaam cad, Canon EOS 7D, sida laga soo xigtay dib u eegista user, waxba ma uu is beddelay. Waxay bixisaa waxqabadka sare ee tiro balaadhan oo ah xaaladaha iftiiminta. Pictures aan la hoos geliyey wax la saxo xad-dhaaf ah, iyo marka macluumaadka toogashada waxaa laga heli karaa oo ku saabsan midabka ah ee iftiinka.

Sida caadiga ah, 7D EOS leeyahay set oo ah Hababka pre-rakibay images (caadiga ah, sawirka, muuqaalka dhirta, dabiiciga ah, sax ah oo monochrome) iyo 3 user. Waxaad xakamayn kartaa macaamiloon ah, ka duwan, robab iyo cado midabka iyo qaab dhismeedka monochrome. mode Standard u muuqataa yara oversaturated, sidaa darteed adeegsadayaasha door bidaan in ay isticmaalaan fursadaha dabiiciga ah ama dhabta ah.

Electricity

Camera Canon 7D ku qalabeysan yahay iftiin midabka (iFCL) iyo dhanka Electricity-63-zone. Si loo go'aamiyo gaadhista ku habboon, waxa uu u adeegsanayaa macluumaadka ku saabsan masaafada inay wax ka soo nidaamka AF ah, iyo macluumaad ku saabsan midab iyo iftiin. Halkii ay ka mid shidma ee 7D EOS yihiin laba ka mid ah: mid ay jawaab u tahay qaybaha cas iyo cagaar ah, oo kale ah - on cagaaran, iyo buluug. Sidaas darteed, habka la isticimaalay uu yahay mid yar oo xasaasi ah oo ay iftiinka ugu cas.

Tan iyo macluumaadka waxaa loo isticmaalaa autofocus, kaalinta dhibic AF waa muhim. Tusaale ahaan, haddii waxa uu ku yaalaa on cawska, sawir fiican loo muujiyey, iyo samada daruuro noqdo overexposed. Haddii aan diiradda on daruuraha, iyagu waa faahfaahsan, oo ciidda ku soo baxday underexposed. Inkastoo dhanka Electricity-sameyaan uu noqday mid tayo xaaladaha qaarkood, sida in hababka badan oo la mid, ma la qabsan karaa xaaladaha daruuro leh.

Marka way adag tahay in ay diiradda saaraan qayb gaar ah oo goobta - tusaale ahaan, madaxa ciyaaryahan gaar ah ciyaar kubadda cagta ah.

Auto dooro sixitaanka 19 dhibcood Canon 7D dib u for walxaha cagabadnayn guurto, iyo camera waxay u egtahay in la raadiyo bartilmaameedka ugu dhow iman kara. In sawir AI Howlsocodsiinta kartaa AF dhibic bilowga iyo camera waxaa raad. In hababka kuwan, waxyaalaha firfircoon lagu muujiyey markii AF Custom Function III-10, sidaas awgeed waa arrin fudud in la arko ama aan wax saxda ah ee kuwan raadkaygay camera ah.

Xaaladdan oo kale, doorashada photo waxaa gacanta ku sameeyey, laakiin 7D EOS waxaa loo isticmaali karaa oo dhibcood ku wareegsan. Sida laga soo xigtay war celin user, waa mid aad u faa'iido badan marka toogtay isboortiga. Marka la barbardhigo auto ka dooro 19 dhibcood hab AF AI Howlsocodsiinta, hareereysan barta aan la iftiimiyay marka ay firfircoon.

Laba fursadaha in menu user ah, dareen ee raad AI Howlsocodsiinta (III-1) oo AI Howlsocodsiinta AF (III-3), ku darayaa dabacsanaan dheeraad ah marka diiradda dhaqaaqin maadooyinka. fursadaha noocan oo kale ah ayaa hore u codsatay kaliya in Mark 1m ah III iyo 1Ds Mark III. Waxay ogaado haddii 7D ay sii wadi in ay diiradda saaraan mawduuca marka dhaw shayga waa in jir ah, iyo haddii aan, sida ugu dhakhsaha badan waa in ka jawaabaan. Ujeedada shaqadooda waa in ay caawiyaan sawir aad ula socoto oo aad ku xiran iyo, haddii loo baahdo, si ay isu ilowsiiyaan muuqaalka lama filaan ah, tusaale ahaan, column ee ku yiilleen markii panning. Guud ahaan, nidaamka AF Canon 7D milkiilayaasha dib u eegista lagu magacaabo cajiib ah. Tan iyo walxaha waa fudud si ay ula socdaan in viewfinder ah, tirada tallaallada uu guul ka badan 90%.

Inkastoo-dareen sare image EOS 7D leh dareen taabasho aan soo faqayo, waxay u badan macaan badan 50D yihiin. Frames eegi weyn ee monochrome iyo halftones madow yihiin jeebbooyin lahayn.

On screen kombiyuutarka xasaasi aadka jpeg-images waxaa ka buuxa si faahfaahsan, laakiin waxaa jira jaamaha qaar ka mid ah midabka. Tani ma aha la jecel yahay, laakiinse iyagoo keliya ayaa la arki karo hoos weyneeyey ilaa size A3 yihiin. Image dhigay in ISO 6400 iyo wixii ka sareeya, kala duwan pixelation cas random.
