Nikon Z9 - kamera isina mechanical shutter: izvi zvinorevei kune mileage

Iyo Nikon Z9 ndiyo mhedziso yepamusoro yeNikon Z system uye imwe yemakamera epamusoro tekinoroji akambogadzirwa. Yakava yekutanga nyanzvi kamera yaNikon isina mechanical shutter zvachose. Iine yekupedzisira-inokurumidza yakazara yakazara yakazara BSI CMOS sensor, kamera inoburitsa 120fps yemagetsi kupfura, 4K 120p uye 8K vhidhiyo-ese asina imwechete inofamba mechina chinhu muvhavha system.

Kusavapo kwechivharo chemuchina chinoshandura zvakanyanya nzira yekuongorora kupfeka. Mubvunzo wechinyakare "chii chinonzi shutter kufamba?" nokuti Z9 inotora zvinoreva zvakasiyana zvachose. Panzvimbo yekupfeka uye kubvaruka pazvivharo, paunenge uchiongorora Z9 yakashandiswa, zvinhu zvakakosha ndezvi: huwandu hwemafuremu akapfurwa (mutoro pamagetsi), mamiriro e sensor uye bayonet mhete, pamwe nenhoroondo yebasa. Kunzwisisa mutsauko kwakakosha pakuita smart kutenga.

Frame counter mune kamera isina mechanics: inoshanda sei

Kunyangwe iyo Z9 isina zvivharo, iyo EXPEED 7 processor ichiri kuchengeta rakasimba reti yehuwandu hwepfuti dzakatorwa. Iyi counter (ShutterCount kana ImageCount) inoratidza huwandu hwemifananidzo yakachengetwa - ingave mafuremu ega kana kuputika pa120 fps. Iyi nhamba ndiyo chiratidzo chikuru che "mutoro" pamagetsi emagetsi ekhamera.

Nyanzvi yekuzivisa Z9 ine mileage ye500,000 mafuremu mutoro wakakomba pane buffer flash memory, matrix uye kutonhora system. Kusiyana nechivharo chemuchina, chinodhura imwe mari kutsiva, matambudziko ane zvikamu zvemagetsi anogona kudhura zvakanyanya. Naizvozvo, kuziva iyo chaiyo "electronic mileage" yeZ9 kwakakosha sekuziva iyo mechanic mileage yemamera akajairika.

Maitiro ekubvisa furemu counter kubva kuNikon Z9 NEF mafaera

Iyo EXPEED 7 processor inorekodha furemu kuverenga data mune metadata yefaira rega rega rainochengeta. Kune iyo Z9, iyi teki inoratidza huwandu hwese hwema sensor revolutions - inova analogue yakananga yevhavha counter yemakamera ane mechanics.

Iyo data iri muEXIF ​​yakajairwa MakerNotes block. Kuti uongorore, iwe unoda iyo yekutanga NEF faira kubva kumemori kadhi - nguva dzose isina yepakati kugadzirisa muzvirongwa zvebato rechitatu. Sevhisi yedu inotsigira iyo Z9 fomati uye inonyatso kuratidza iyo counter data yeiyi yakasarudzika kamera.
