Makasitomala apamwamba opangidwa ndi makamera akukula pakudziwika kwa ojambula akuyang'ana kuwonjezera khamera kwa mafano awo a DSLR. Makina opangidwa ndi makalera oterewa ndi ochepa kwambiri kuposa anzawo a DSLR, koma amapereka zinthu zambiri zomwe zimapangitsa kuti azitha kuwombera zithunzi zamtengo wapatali pamtengo wotsika pang'ono poyerekeza ndi kamera ya DSLR ndi chida cha lenti.
Imodzi mwa zopereka za Canon mu gawo ili ndi PowerShot G7 X. Ngakhale kuti chitsanzo ichi chimanyamula PowerShot moniker, sichifanana kwambiri ndi mfundo yopepuka ndi kuwombera, zitsanzo zoyambirira zomwe zimakhala ndi banja la PowerShot.
G7 X imapereka khalidwe lapamwamba lajambula ndi capsenti yake ya CMOS 1-inch. Imakhalanso ndi lenti 1.8, yomwe ili yabwino kwa zithunzi zowonongeka ndi malo osaya kwambiri a munda, zomwe zimapangitsa chitsanzo ichi kukhala choopsya cha kuwombera zithunzi. Ndipo Canon wapereka chithunzi chojambula kwambiri cha LCD chomwe chimapangitsa madigiri 180, ndikukupatsani njira yosavuta yojambula zithunzi zanu.
Pa mazana angapo madola Canon G7 X ndi chitsanzo chabwino kwambiri, monga momwe mungathere kamera ya DSLR yomwe ili mkati mwazitsulo zingapo zazing'ono zofanana. Ndipo ngakhale kuti malingaliro opangidwa ndi 4.2X opangidwa ndi zithunziwa ndi ofooka kwambiri kuposa angapo otsegula makamera, poyerekeza ndi zitsanzo zina zapamwamba zogwiritsira ntchito lens, zojambulazo za 4.2X ndizoposa. Malingana ngati mukumvetsa makamerawa ali ndi zolepheretsa chifukwa chazing'ono zojambulajambula, china chirichonse chotsatira ichi ndi chodabwitsa, ndipo mumakonda zithunzi zomwe mungayenge nazo.

Kuphatikizidwa kwa chithunzi chachikulu chajambula ndi ma digapixel 20.2 otsimikiziranso zimapereka khalidwe la kanema la Canon PowerShot G7 X. Chitsanzochi sichikugwirizana kwambiri ndi khalidwe la zithunzi za kamera ya DSLR, koma ili pafupi kwambiri, makamaka poyerekeza ndi DSLRs zazing'ono.
Malo apamwamba omwe G7 X sangagwirizane ndi khalidwe la DSLR ndilokuwombera pamalo otsika kumene muyenera kuyimitsa ISO kukhazikitsa. Ngakhale kuti DSLRs imatha kusamalira ISOs ya 1600 kapena 3200 pamene imakhala phokoso lochepa kwambiri, muyamba kuzindikira phokoso ndi PowerShot G7 X pafupi ndi ISO 800.
Kumene G7 X ili bwino ndi pamene mukujambula zithunzi za zithunzi. Mukhoza kugwiritsa ntchito malo otseguka otsegula mpaka f / 1.8 kuti mupange zithunzi ndizomwe zimakhala zakuya kwambiri. Mwa kufotokoza mbiriyi mwanjira imeneyi, mudzatha kupanga zithunzi zooneka bwino pamene mukujambula zithunzi.
Kuti apange zithunzi zowonjezereka, Canon yapatsa chitsanzo ichi mphamvu yokonza RAW ndi JPEG zithunzi panthawi yomweyo.
Kuchita
G7 X ndi kamera yofulumira kwambiri, yopanga mafano mofulumira kufika pa 6.5 mafelemu pamphindi, yomwe ikuchitika bwino kwambiri. Komabe, tifunika kuzindikira kuti kuthamanga kokongola kumeneku kumapezeka mu kujambula kwa JPEG. Ngati mukuwombera RAW , mungathe kuyembekezera kuti kamera ichepetse bwino.
Mukhoza kugwiritsa ntchito chitsanzo ichi mwa njira yoyendetsera, mwatsatanetsatane, kapena chilichonse chomwe chiri pakati, zomwe zikutanthauza kuti kamera ikhoza kukuthandizani kuti mukhale ndi luso la kujambula pang'onopang'ono, ndikuwonjezera kulamulira kwambiri pamene mukuphunzira zambiri.
Makina a autofocus a kamera ndi ochititsa chidwi, ojambula mofulumira komanso olondola muzochitika zonse zowombera. Muli ndi ndondomeko yotsatiridwa ndi kamera ya Canon, koma ndi zovuta pang'ono kuzigwiritsa ntchito. Sindinaganize kuti ndikufunika kugwiritsira ntchito ndondomeko yamakono panthawi yomwe ndayesedwa ndi G7 X chifukwa mawonekedwe a autofocus anali abwino.
LCD ya 3.0-inch yokhala ndi chitsanzo ichi ndi yowala kwambiri. Canon inapatsa mphamvu zojambula za PowerShot G7 X, koma izi sizingakhale zamphamvu chifukwa zingatheke kuti makamera a Canon a mitundu yonse asakhalenso ndi mphamvu zowonjezereka chifukwa chokonzanso machitidwe ake komanso mawonekedwe ake.
Kutha kwa batali kwa nthawi yayitali kungakhale bwino ndi kamera iyi, momwe mayesero anga anasonyezera G7 X yokha inalembedwa zithunzi 200 mpaka 225 pothandizira.
Kupanga
Canon inapatsa G7 X mabatani angapo ndi kujambula, zomwe zimapangitsa kuti zisinthe kusintha kwa kamera mofulumira. Mukhozanso kupotoza mphete yamatabwa yowonongeka kuti mupange kusintha kwina - zomwe mungathe kuziwonetsera kupyolera mumasewero owonetsera - mofanana ndi zomwe mungachite ndi kamera ya DSLR.
G7 X ili ndi nsapato yotentha, yowonjezera kuwonjezera kwa zipangizo zosiyanasiyana, kuphatikizapo phokoso la kunja. Ma Wi-Fi ndi NFC mateknoloji amapangidwa mu kamera iyi, kukupatsani njira zambiri zoti mugawane zithunzi. Mwamwayi, G7 X alibe chiwonetsero .
Kuperewera kwa makina akuluakulu osakanikirana ndi chitsanzochi kungakhumudwitse ojambula, makamaka omwe angakhale akuganiza kuti amasamukira kuchoka ku kamera yaikulu yojambula kamera yokhala ndi 25X kapena zojambula bwino. Choncho musayembekezere kutenga Canon G7 X paulendo wanu wotsatira, kuyembekezera kuwombera zithunzi zoyenera za mbalame kapena nyama zina zakutchire kutali. Komabe, makamera ambiri m'kalasiyi amapereka zojambula zochepa kapena osasanthula konse, kotero kuyeza kwa 4.2X kufanizitsa bwino.
