Mafungiro asiriwo anozivikanwa: "Kamera yakangopfura vhidhiyo, iyo shutter yakaita senge nyowani"

Pakusarudza kamera yakashandiswa (kunyanya makamera akasanganiswa seNikon Z6 II, Panasonic GH5, Sony A7S III), kushambadzira kazhinji. pane mutsara unoti: *“Camera yakashandiswa kupfura vhidhiyo chete, shutter haina kusakara!”*.

Izvi ndezvechokwadi kubva pakuona kwefizikiki ye mechanical shutter uye hupenyu hwematrix?

1. Mechanical shutter yekupfura vhidhiyo

Munguva yekupfura kwevhidhiyo, iyo mechanical shutter inovhura **chaiyo 1 nguva pakutanga kwevhidhiyo clip ** uye inovhara kamwechete. mushure mekudzvanya bhatani re "Stop".

• Kana mushandisi akarekodha zana mavhidhiyo akareba emaminitsi makumi matatu imwe neimwe, iyo mechanical shutter yakatangwa chete ** ka100 nguva **!
• Panyaya yekuvhara machira ekuvhara, kupfura kwevhidhiyo kunenge kwakachengeteka zvachose.

2. Njodzi dzakavanzwa dzemavhidhiyo makamera: Kupisa kwematrix uye lasers

Kunyangwe machira evhavha acharamba akakwana, kamera inoshinga kupfura vhidhiyo iri pasi pedzimwe njodzi:

1. Thermal degradation yematrix:Paunenge uchiramba uchirekodha 4K/8K vhidhiyo, iyo yekuverenga matrix kupisa kusvika +60°C. Kuwedzeredza kwenguva refu kunotungamira mukuwedzera kwehuwandu hwevakafa uye kupisa pixels.
2. Ngozi dzekirabhu lasers:Pamakonzati nemichato, laser inoratidza ipapo inopisa mapixels pairi zvachose vhura matrix.
3. Rekodha bhatani / bayonet kupfeka:Kubva kune inorema vhidhiyo rigs uye checkered body kit.

Kuenzanisa tafura yekupfeka mumifananidzo nemavhidhiyo

Chikamu	Kutora mifananidzo kwakadzama	Kupfura kwevhidhiyo kwakanyanya
Mechanical shutter	Kupfeka kwepamusoro (100k-300k mafuremu)	Zvipfeko zvishoma (1k-5k mafuremu)
Matrix thermal load	Low (pulse)	Yakakwirira (inopisa nguva dzose)
Ngozi yemalaser matanda	Yakaderera (shutter yakavharwa)	High (sensor yakavhurika)
