Pentax K-50: ndemanga, chithunzi, mwachidule

Pentax ndi kampani yakale, yomwe inali kupanga makamera kuyambira 1952 kutali. Mphamvu imeneyi inali mpainiya m'magetsi ojambula zithunzi. Ubwino ndi zatsopano za zipangizo za Pentax zimakhudza maganizo. Komabe, mu 2008, chifukwa cha vutoli, kampaniyo inagwidwa ndi chimphona Ricoh ndi Hoya. Ndipo ngakhale palibe kampani ngati Pentax, phototechnics imapangidwa pansi pa chizindikiro ichi.

Ndikoyenera kudziwa kuti Rioch amagwira chizindikiro. Pentax akadali ofanana ndi mawu "khalidwe". Komabe, kutchuka kwa mtundu umenewu ndi wotsika kwambiri. Chifukwa chiyani? Chowonadi ndi chakuti msika wa chithunzithunzi chajambula kwenikweni unagawidwa ndi zimphona Nikon ndi Canon. Zochepa zojambula sizinali zofunika. Koma mtundu uwu wamanyazi sukhalitsa nthawi yaitali. Inde, posachedwapa, SLR yatsopano yotchedwa Pentax K-50 inalengezedwa . Kodi ndi wapadera bwanji pa kamera iyi? Kodi Rioch akukopa bwanji wogula? Mayankho a mafunsowa angapezeke m'nkhani ino.

Pentax K-50: Zowonongeka

Wogula zamakono akuvuta kudabwa. Komabe, kamera yopanga Pentax K-50 inatha kuchita izi. Iye anapanga kumverera kwenikweni. Koma ndi chiyani chapadera pa selo iyi? Mwina chipangizochi chimakhala ndi makhalidwe abwino kwambiri? Mwinamwake zonsezi ndi ergonomics za chipangizochi? Ayi, chirichonse chiri chophweka kwambiri. Phindu lalikulu la Pentax K-50 ndikulinganiza kwake. Akatswiri ochokera ku Rioch adagwiritsa ntchito njira yothetsera chidwi komanso yosasinthasintha, yomwe mungathe kuiwerenga pansipa.

Kupanga

Ngakhale poyang'ana pa khamera, zimakhala zomveka bwino kuti wopanga akugulitsa pamapangidwe a chipangizocho. Poyerekeza ndi chitsanzo cha K-30, mizere ya kanyumba imayenda bwino. Matte ya matte amapangidwa ndi polycarbonate yapamwamba kwambiri. Pamaso pa kamera mungathe kuwona zowonjezera zitsulo, zomwe zimapereka ergonomics zina. Zikomo kwa iwo, kamera ili bwino kwambiri ndipo sichiyesa kuthamangira. Chosavuta chachikulu ndicho kulemera kwa chipangizochi. Kamera ikagwiritsidwa ntchito kwa nthawi yayitali, manja amatopa komanso amatha. Ndipo ambiri, Pentax K-50 - lalikulu kwambiri pakati pa makamera ofunikira mtengo womwewo.

Thupi liri ndi zisindikizo 81 za mphira, zomwe zimapanga chitetezo. Chifukwa cha ichi, makina amatha kutetezedwa ku madzi, chisanu, mvula, fumbi, ndi zina zotero. Choncho, n'zotheka kugwiritsa ntchito SLR ngakhale panthawi yovuta. Inde, mu mvula yamphamvu imakhala yosafunika kuwombera (ndipo zithunzi zidzatuluka chifukwa chosaoneka bwino). Komabe, kamera idzapulumuka mvula yochepa. Kuwonjezera apo, kamera ikhoza kutengedwera bwino ku gombe. Pambuyo pake, thupi limakhala lolimba, ndipo izi zikutanthawuza kuti palibe mchenga umodzi womwe udzalowa mkati. Izi ndizochepa kwambiri mu makamera a msinkhu uwu. Kodi mumakayikira bata la kamera iyi? Pa ukonde, rollers roll yomwe Pentax ili ndi mchenga wabwino, kenako chipinda chimatsanulira ndi madzi. Ngakhale atatha kuzunzidwa kotero, kamera imakhala ikugwira ntchito.

Koma, mwinamwake, chinthu chachikulu mu Pentax K-50 yatsopano (chithunzi chikhoza kuwonedwa pamwamba) - kusiyana kwakukulu kwa mitundu. Chomwe chiri chochititsa chidwi kwambiri, wogula ali ndi mwayi wodziimira yekha kupanga kapangidwe ka chidutswa chake. Mitundu isanu ndi umodzi ya chogwirizanitsa ndi mitundu iwiri ya thupi pamodzi imakulolani kusonkhanitsa pafupifupi 120 kuphatikiza. Ndipo izi ndi zosangalatsa, ngakhale zili zoopsa. Kotero, mungathe kupanga kamera yapadera yomwe imatha kugogomezera umunthu, dziko lamkati la mwiniwake. Kuwonjezera pa kukonza, chipangizochi chiri ndi zinthu zingapo zosangalatsa, zomwe mungathe kuziwerenga m'munsimu.

Kugwira ntchito

Zambiri mwazimenezo zinapita ku K-50 kuchokera patsogolo pa K-30. Choncho, kamera yatsopano imagwiritsira ntchito 16.28 Mp matrix (kukula kwa APS-C). Chifukwa cha izo, kamera imapangitsa kukhala wokongola kwambiri komanso yoyandikana ndi zochitika zenizeni.

Komabe, K-50 si kope la K-30. Chipangizo chatsopano chimapangitsanso ndondomeko yowonjezera yosintha. Izi zinapangitsa kuti chiwerengero cha ISO chikhale chokwanira mpaka 51200. Kuonjezerapo, Pentax ya ubongo inalandira njira yatsopano yoyendetsera SAFOX AF IXi +. Amapereka chidziwitso chokwanira komanso mofulumira kwambiri.

Kumvetsetsa ndi koyenera komanso chikhazikitso chazithunzi. Chifukwa chake, kufotokoza kwa chithunzichi pakuwombera kumachitika kangapo ngakhale popanda kugwiritsa ntchito katatu. Chifukwa cha pulogalamu yabwino, kamera imatembenuka mofulumira ndikuyang'ana. Ndiyeneranso kukumbukira kuti liwiro la kuwombera mndandanda ndilofanana ndi mafelemu 6 pamphindi. Kwa zipangizo za amateur, ichi ndi chizindikiro chabwino.

Miyeso

Pentax K-50 kamera ili ndi miyeso yambiri yotsegula. Zina mwazo zimakhala zosavuta, zowonjezera, ndi zomveka (pafupifupi 19 zosankha), ndi mavidiyo. Musaiwale opanga a Tv classic ndi Av. Komanso, iwo anawonjezeredwa ku Sv (kutsimikizika kumaperekedwa patsogolo) ndi Tav (choyamba chimaperekedwa kuwonetsetsa). Komanso palinso njira zingapo zosagwiritsira ntchito.

Chithunzi chowonekera chimapereka maonekedwe a 100%. Pulogalamu yamasentimita atatu ali ndi chiganizo chokwanira (pafupifupi mapepala 921,000). Chifukwa cha ichi, mutha kuyesa ubwino wa chithunzi mwamsanga mutatha kuwombera. Kamera imapanga chithunzi ndi ndondomeko ya 4928 x 3264. Zithunzizo zimasungidwa mu mawonekedwe a RAW ndi JPEG.

Zida

Mwa zina, Pentax K-50 imatha kuponya mu HDR. Izi zimakuthandizani kuti muwonjezere kwambiri kukula kwake. N'zotheka kukhazikitsa HDR (chizindikiro cha ntchito, etc.). Mukhoza kuwombera mmanja mwanu, palibe chofunikira cha katatu. Komabe, pali zovuta kwambiri apa - kugwiritsira ntchito ndi kukonza chithunzicho kumatenga nthawi yaitali (pafupifupi masekondi 13). Ngakhale kuli koyenera kuti izi ndi mofulumira kuposa liwiro la yemweyo K-30.

Pentax K-50 ili ndi kayendedwe kazitsulo kothandizira kutchedwa ShakeReduction. Zimabweretsa zotsatira zolakwika za kugwedeza kwa chipangizo, chomwe chimapangitsa chithunzi kukhala chowonekera bwino. Ndiyeneranso kuzindikira kuti kamera ikhoza kukonza chromatic aberration ndi kupotoza. Zina mwa zosangalatsa zosangalatsa, mungathe kunena kuti mwina mungathe kuwombera. Chifukwa cha izo ndizotheka kulandira zithunzi 2 mpaka 999 kwa nthawi yaitali kuchokera 3 masekondi mpaka maola 24. Pachifukwa ichi, mukhoza kufotokoza chiyambi ndi mapeto a kafukufuku molondola.

Pentax K-50: ndemanga

Anthu adalandiridwa bwino ndi kamera yatsopano ya SLR. Anthu ambiri ankakonda lingaliroli ndi mitundu yosiyanasiyana (chifukwa cha kutchuka uku Pentax K-50 imagwiritsidwa ntchito ku Europe). Zina mwa ubwino wa ogula amadziŵa kukhalapo kwa mitundu yosiyanasiyana yojambulira, kujambula kamangidwe ka chipangizo ndi kukana zochitika kunja.

Komabe, osati popanda chiopsezo. Kulemera kwa chipangizochi kumachepetsa kwambiri ergonomics yake, yomwe yanyansidwa ndi ogwiritsa ntchito ambiri. Ndiponso, kusokonezeka kumayambitsidwa ndi kukonzanso kwazithunzi kwa zithunzi nthawi ya HDR-kuwombera.

Zotsatira

Pentax K-50 ndi kamera yokondweretsa, yomwe ingakhale yopindulitsa kwambiri yomwe ingathe kusintha maonekedwe a chipangizocho. Komabe, kuwonjezera pa kukonza, kamera ili ndi ntchito zambiri, njira yabwino yotetezera. Ndiponso, mtengo, womwe ndi dongosolo laling'ono kwambiri kuposa la ochita mpikisano, sungakhoze koma kusangalala.
