Kutarisa mileage yesemi-professional tank SONY SLT-A77V

SONY SLT-A77V haisi kamera chete, imotokari yekurevera yezvombo mune muviri wemagnesium, wakagadzirirwa nyanzvi uye nehutsinye hwekushanda mamiriro. Kudzivirirwa kweguruva uye unyoro, imwe skrini, chiyero chekupenga chemoto chegumi nemaviri mafuremu pasekondi - zvese izvi zvakaita kuti ive sarudzo yakanaka yemuchato, yemitambo uye yemhuka dzesango. Iyi ndiyo "nyanzvi" mamiriro anoita kuti kutarisa mileage pamusika wechipiri ive nzira yakakosha.

Kusiyana neamateur makamera anogara mukesi kwemakore, iyo A77V yakashanda nesimba. Munguva yekupfura kwemuchato kwakanyanya, shutter inogona kupfura kubva pa3 kusvika ku5 zviuru nguva. Kwekufamba kwegore, kamera yakabata zviri nyore zviuru zana mafuremu. Nokudaro, kutaridzika kwakakwana kwechiitiko che magnesium hakufaniri kukunyengera: mukati me mechanics inogona kupfekwa kusvika kuguruva.

Shutter hupenyu pa12 mafuremu pasekondi

Kupfura pamafuremu gumi nemaviri pasekondi muyedzo wakakura kune chero mechanic unit. Kumira kushushikana kwakadai, mainjiniya eSony akagadzira chivharo chakasimbiswa cheSLT-A77V vachishandisa alloys anogara uye kabhoni fiber. Kufamba uku kwakaringana zvakatemerwa zviri pamutemo 150,000 yakavimbiswa mashandiro.

Mukuita, makamera aya anowanzopona kusvika ku200 kana 300 zviuru zvefuremu, asi iyi yatova lottery. Kutenga chitunha cheA77V chakashandiswa chine mileage ye120-140 zviuru zvemafuremu zvinoreva kutenga mudziyo "kutsiva chivharo," icho chinofanira kudzikisa zvakanyanya mutengo wayo wemusika. Kana iwe ukawana sampuli inosvika zviuru makumi mashanu ekutenderera, uku ndiko kubudirira kukuru.

Kubvisa data rekupfeka kubva kuEXIF ​​fomati

Midziyo yekutengeserana inofanirwa kuve nenhoroondo yekushanda yakajeka, uye mainjiniya eSony akafunga izvi. Iyo yepakati processor yemudziyo inochengeta inoenderera yakasimba rekodhi yeese activation yemuviri yemaketeni. Kufamba kwega kwega kunowedzerwa kune isina-resettable counter, inova hardware yakadzivirirwa kubva mukushandiswa kwevashandisi.

Iyi counter yakanyudzwa chinyararire mune yega yega EXIF ​​​​metadata (muchikamu chekushandisa cheMakerNotes). Hauzozviwani mumidziyo yefaira muWindows, asi nealgorithms ekurudyi, ruzivo urwu rwunotorwa zviri nyore kubva kune yekutanga RAW (.ARW) kana JPG faira.
