I-Sigma 85mm f / 1.4 ubugcisa okanye i-135mm f / 2 ubugcisa obuza kulo nyaka

I-Sigma iphinde ihlebe ukuba icwangcisa ukumiliselwa kwelensi yothotho ye-Art ene-aperture eqaqambileyo, enokuba yenye yeemodeli ezingama-85mm f / 1.4 okanye 135mm f / 2.

Iinyanga ezine zidlulile okoko uSigma wabhengeza ilensi entsha. Inkqubo ye- 24mm f / 1.4 Ubugcisa be-DG HSM Iyunithi yaziswa ekuqaleni kukaFebruwari 2015, kodwa ikamva liphethe iyunithi yomnxeba kubalandeli benkampani.

Njengoko icandelo le-engile ebanzi ligutyungelwe ngumenzi osekwe eJapan, abalandeli bakaSigma basalinde ezinye iifoto zeefowuni kunye neeyunithi ezimbini sele zikhankanyiwe ngaphambili. Kubonakala ngathi inamba enye yomnxeba isendleleni kungekudala kwaye iya kuba ne-85mm f / 1.4 Art okanye 135mm f / 2 Art.

Ilensi entsha yeSigma 85mm f / 1.4 inokumiliselwa kwi-2015. Iya kuba yimodeli yobuGcisa enomgangatho womfanekiso ofana noZeiss Otus.

I-Sigma 85mm f / 1.4 Iilensi zobugcisa lolona khetho lukhetho lwenkampani elandelayo

Kukho ingxoxo eqhubekayo malunga nekamva lomnxeba weSigma. Indawo yokuhleba icebise ukuba inkulumbuso elandelayo yefowuni eza kuphuma iya kuba yinguqulelo yobugcisa engama-85mm f / 1.4.

Ingxaki kule modeli kukuba uguqulelo lwangoku lwasungulwa ngo-2011, kanye phambi kweprojekthi ye-Global Vision, ke abasebenzisi baya kuziva bengenamfuneko yakuphucula okwangoku.

Nangona kunjalo, imithombo ixela ukuba ikamva I-Sigma 85mm f / 1.4 Iilensi zobugcisa ziya kubonelela ngomgangatho womfanekiso ofana nalowo weZeiss Otus 85mm f / 1.4 nakwiqhezu leendleko.

Umenzi waseJapan ubonakalisile amandla akhe kumgangatho ophezulu we-optics ngamaxabiso afikelelekayo, ke mhlawumbi i-Sigma 85mm f / 1.4 iilensi zobugcisa zinokuvakala kwaye zingenisa inzuzo emva kwayo yonke loo nto.

Ukhetho lwesibini lukaSigma luya kuba yi-135mm f / 2 iilensi zobugcisa

Ukhetho lwesibini kwi-Sigma telephoto prime yi-135mm f / 2 Art. Akukho ilensi enjalo kulungelelwaniso lwenkampani, ke iya kwamkelwa ngabafoti kwihlabathi liphela.

ICanon kunye neNikon zinee-135mm f / 2 zokukhanya. Nangona kunjalo, zithathwa njengezindala, njengoko zakhutshwa kwiminyaka emininzi eyadlulayo, ke iSigma inokubamba uninzi lwentengiso kunye nemveliso yayo.

Nangona uSamyang kunye noZeiss baneelensi ze-135mm f / 2 zeekhamera ezizeleyo, inguqulelo kaSigma yayiya kuxhasa itekhnoloji ye-autofocus. Hlanganisa oku kunye nomgangatho ophezulu womfanekiso kwaye ufumana iresiphi yokuphumelela.

Ukuyijonga, i-135mm f / 2 iilensi zobugcisa zinokuvakala ngakumbi, kodwa akukho lwazi lungako malunga nale optic, yiyo loo nto i-Sigma 85mm f / 1.4 iilensi zobugcisa kuthiwa zikwisikhundla esiphambili sokuba ngumnxibelelanisi olandelayo wefowuni ngokukhanya.
