I-CES 2014: Sigma 50mm f / 1.4 DG HSM Iilensi zobugcisa ngoku ezisemthethweni

I-Sigma yazise iilensi ezimbini ezintsha, i-50mm f / 1.4 DG HSM Art kunye ne-18-200mm f / 3.5-6.3 DC Macro OS HSM Contemporary, kwi-Consumer Electronics Show 2014.

Azikho iilensi ezininzi kakhulu ezityhilwe eLas Vegas, eNevada kwesinye seziganeko ezinxulumene netekhnoloji enkulu yonyaka. Ngombulelo, i-CES 2014 ayivalanga iingcango zayo, okwangoku, kwaye izibhengezo ziyaqhubeka nokuza.

I-Sigma iye yaxhuma kule bandwagon kwaye ityhile isibini sokukhanya kubafoti kwihlabathi liphela. Enye yazo yenzelwe iikhamera zesakhelo esipheleleyo, kodwa kufuneka isebenze kwiimodeli ze-APS-C, nayo, ngelixa enye ijolise ngokukodwa kubadubuli be-APS-C.

I-Sigma ibhengeza i-50mm f / 1.4 DG HSM yeelensi zobugcisa ngoyilo oluphuculweyo lwangaphakathi kunye nefomula yokubonakalayo

I-Sigma 50mm f / 1.4 DG HSM iilensi zobugcisa zijolise kwiikhamera ezipheleleyo zesakhelo, kodwa ziya kusebenza neemodeli ze-APS-C, nazo.

Umbutho osekwe eJapan ukwazile ukumangalisa iilensi kulo nyaka ka-2013, ikakhulu ngenxa i-18-35mm f / 1.8 DC HSM yokukhanya. Ngoku lixesha elifanelekileyo lokunyusa umdlalo wayo ngoncedo lweSigma 50mm f / 1.4 DG HSM Art lens.

Le mveliso ithathe indawo yemodeli esekho kubasebenzisi. Nangona kunjalo, i-50mm yangoku f / 1.4 I-EX DG HSM isekwe kuyilo "oludala", ngelixa ezemidlalo ezitsha ezili-13 zahlulwe zangamaqela asi-8 nge-9-blade rounded diaphragm.

Inguqulelo entsha iza ne-SLD (Special Low Disersion) yezinto zeglasi ezilapha ukunciphisa i-chromatic aberrations. Izinto ze-aspherical kunye nepeyinti zikwanciphisile ukugqwetha, ukuphefumla, ukuvutha kunye nezinye iziphene ezibonakalayo ezinokubonakala kwifoto.

I-Sigma 50mm f / 1.4 DG HSM iilensi zobugcisa eziza kukhutshelwa iikhamera zeCanon, iSigma, iSony kunye neNikon

I-Hyper Sonic Motor ye-50mm f / 1.4 DG HSM yoBugcisa entsha ibonelela nge-autofocus ethe cwaka. Ukubonelela nangakumbi kwixa elizayo, i-optic iyahambelana ne-Sigma USB Dock eyaziwayo.

Ngaphambi kokuhlaziya imveliso ye-firmware, umenzi uthi abafoti banokuyonwabela i-bokeh enomtsalane ekhutshwe yilensi. Nangona kunjalo, umhla wokukhutshwa kunye nexabiso alaziwa.

Iilensi zilinganisa i-3.35-intshi ngobubanzi kunye no-3.94-intshi ubude, ngelixa intambo yayo yokuhluza ime kwi-77mm. Ubunzima bebonke zii-1.04 lbs, nangona zinokwahluka ngokuxhomekeka kwintaba.

Ukuthetha ngayo, le optic ephambili iyahambelana neCanon, Sigma, Sony, kunye neikhamera ezipheleleyo zesakhelo, nangona izakusebenza neemodeli ze-APS-C, nayo.

I-Sigma yazisa ilensi entsha yelensi: 18-200mm f / 3.5-6.3 DC Macro OS HSM ye-APS-C DSLRs

I-Sigma 18-200mm f / 3.5-6.3 DC Macro OS HSM lens iya kufumaneka kungekudala kwiikhamera ze-APS-C ezivela eCanon, Nikon, Sigma, Pentax, nakwiSony ene-35mm elingana ne-27-300mm.

Iilensi zesigma sesibini yi-18-200mm f / 3.5-6.3 DC Macro OS HSM, njengoko kuchaziwe apha ngasentla. Inxalenye yoluhlu lwemihla ngemihla kwaye iyahambelana neekhamera ze-APS-C ezivela eNikon, Canon, Sigma, Sony, nakwiPentax.

Iza netekhnoloji ye-Optical Stabilizer eqinisekisa ukuba izifundo azijiki ngokungacacanga, into eyamkelweyo ngakumbi, ngakumbi ukufota okukhulu. Nangona kunjalo, iimodeli zikaSony kunye nePentax aziyi kuba nenkqubo ye-OS, kuba uninzi lwezi khamera sele zinobuchwephesha obakhelweyo.

I-Sigma 18-200mm f / 3.5-6.3 DC Macro OS HSM ithathe indawo yemodeli esungulwe emva ngo-2011. Inguqulelo entsha inezinto ezili-16 kumaqela ali-13 anezinto zeglasi zeSLD (Special Low Disersion).

I-Sigma 18-200mm f / 3.5-6.3 DC Macro OS HSM yemilinganiselo yeelensi zangoku kunye nolwazi oluthe kratya

Iilensi zilinganisa i-2.8-intshi ngobubanzi, i-3.4-intshi ngobude kwaye inomsonto we-62mm wokucoca ulwelo. Ikhaphukhaphu kancinci kune-50mm f / 1.4 lens ngaphandle kobude bayo ekugxilwe kuyo njengoko inobunzima be-0.95 lbs kuphela.

Ubuncinci bomgama ekugxilwe kuwo zii-intshi ezingama-15.35 / iisentimitha ezingama-39 kwaye ubuncinci bokuma kume ku f / 22.

Xa ifumaneka, kufuneka inikeze i-35mm elingana ne-27-300mm. Njengomlingane wayo we-50mm, umhla wokukhutshwa kunye nexabiso alichazwanga.
