Canon tab tom tsim L kab nrog f / 4 lo ntsiab muag nrog rau ntau hom f / 2.8 lo ntsiab muag. Lawv me me, pheej yig dua thiab sib dua dua li cov pa, tab sis lawv yog cov khoom zoo thiab muaj cov yam ntxwv xws li nruj thiab lub zog.

Lub f/2.8 series suav nrog cov lo ntsiab muag tshaj lij rau Canon xws li 70-200, 24-70, 16-35 (IS). F / 4 yog cov qauv 70-200, 24-105, 17-40 thiab IS. Qhov kev tshuaj xyuas no yuav tsom mus rau EF 24-105mm / 4L IS USM.

Txoj kev nthuav dav

Qhov tseeb tias lub cuab yeej yog L series, koj tuaj yeem qhia tau sai li sai tau thaum lub lens poob rau hauv tes. Thiab tsis tsuas yog vim muaj lub nplhaib liab ntawm lub hauv ntej ntug - qhov no yog qhia los ntawm nws lub zog thiab kev ntseeg siab. Lub mount hlau yog qhov tsis tshua muaj hnav thiab tsim kua muag dua li cov yas mount, thiab kev tiv thaiv plua plav thiab noo noo yog qhov tseem ceeb thaum tua thaum lub teeb los nag. Lub nplhaib ultrasonic lub cev muaj zog kom raug, sai thiab yuav luag ntsiag to pom qhov ua kom pom tseeb zoo meej. Kev ceev tu hom kuj muaj.

EF 24-105mm / 4L yog Canon lens nrog specifications uas ua rau nwszoo txheej ntawm focal lengths. Tej zaum txawm zoo dua 24-70mm / 2.8L. 24mm muab lub kaum ntse ntse dav. Ob lub lo ntsiab muag npog qhov ib txwm 50mm ntau, tab sis cov qauv no tseem npog cov duab, raws li ntau tus neeg hu 80-100mm focal lengths. Cov koob yees duab puv nrog cov kev txwv no muab cov koob yees duab taub hau thiab xub pwg zoo heev. Qhov 70mm txwv ntawm 24-70 txhais tau tias lub lens no tsis haum rau cov kev txhaj tshuaj no.

Ntxiv rau, tus qauv no zoo kawg nkaus khaws cov toj roob hauv pes, pab pawg neeg thiab cov tsev. Nws yog ib qho ntawm cov hom phiaj dav dav uas koj tsis tuaj yeem nyob yam tsis muaj thiab ua rau lub caij so zoo. Rau cov neeg uas nyiam tua nrog ntev focal ntev, tus qauv yuav muab lub sijhawm zoo li no. Tau kawg, 105mm tsis txaus rau kev yees duab yos hav zoov - nws yuav tsum tau ntxiv nrog telephoto optics 100-400mm / 4.5-5.6L.

Ntawm 670g, lub lens yog qhov sib zog dua li 950g 28-70mm / 2.8 qauv. Txawm li cas los xij, qhov no tsis ua rau nws lub teeb lossis compact.

Qhov siab tshaj plaws aperture ntawm f/4 tsis yog qhov txwv, tab sis tsawg kawg nws zoo ib yam thoob plaws qhov zoom ntau thiab tag nrho kev faib zoo dua li feem ntau zoom lo ntsiab muag ntawm lawv qhov txwv sab saud. Txhawm rau tua sab hauv tsev hauv cov teeb pom kev tsis zoo, qhov siab ISO yuav xav tau. Tab sis ntawm qhov tod tes, lwm qhov kom zoo dua ntawm Canon EF 24-105mm / 4L yog lub teeb tsa hauv cov duab stabilization, uas tso cai rau koj kom lub shutter ceev 3 zaug. Yog li yog tias tus kws yees duab tau txaiscov duab ntse tsis muaj IS ntawm 105mm hauv 1/125s, tam sim no nws tuaj yeem thaij duab hauv 1/15s. Qhov no yog vim li cas lub lens zoo haum rau kev tua sab hauv tsev, tshwj xeeb tshaj yog thaum nruab hnub, txawm tias IS tsis tuaj yeem tiv thaiv cov khoom txav los ntawm qhov muag tsis pom, tsuas yog lub kaw lus nrawm tuaj yeem ua tau. F/2.8 optics EF 24-70, uas tsis muaj IS, lossis qhov me 17-55 yog qhov tsim nyog rau kev ntes cov kev txhaj tshuaj hauv cov teeb pom kev tsawg. Tau kawg, lub teeb tuaj yeem tuaj yeem cawm tau, tab sis nws rhuav tshem qhov chaw ntawm lub teeb ntuj.

Thaum lub lens (nrog rau 70-300 IS) thawj zaug tshwm sim hauv xyoo 2005, thawj cov piv txwv raug kev txom nyem los ntawm flare nyob rau hauv qee yam mob. Tus qauv tsim tau raug kho sai, thiab txij li xyoo 2006 lo ntsiab muag tau tsim tsis muaj qhov tsis zoo no.

Cov khoom siv kho qhov muag yog tsim los ntawm 18 lub ntsiab lus, suav nrog ib qho Super UD thiab peb lub ntsiab lus aspherical, txhawm rau txhim kho cov duab zoo thiab txo qis qhov aberrations txawm tias lub aperture qhib dav.

Lub koob yees duab Canon no tau kaw tag nrho, uas txhais tau tias muaj gaskets nyob rau hauv qhov kev hloov pauv kom pom tseeb thiab zoom rings, nrog rau ntawm lub mount. Txawm li cas los xij, qhov tom kawg yog qhov ua tau zoo tsuas yog thaum siv optics nrog lub kaw lus kaw. Cov no feem ntau yog EOS 1 series khoom siv. Rau kev tiv thaiv ntxiv, Canon pom zoo kom siv 77mm UV lim thaum siv lub lens hauv nag.

Tsim nta

Lub lens zoo kawg nkaus nrog 40D lossis 5D koob yees duab. Nws tsis yog hnyav, tab sis kuj compact thiab xis nyob rau hauv koj txhais tes. Qhov tsuas yog qhov uas cov neeg siv tsis meej pem me ntsis yog tias lub nplhaib zoom nyob rau sab nraub qaum thaum lub nplhaib tsom rau pem hauv ntej. Lwm yam kev tshaj lij lo ntsiab muag rau Canon nrog USM motors (piv txwv li 20-35, 28-135 IS, 17-85 IS) txawv nyob rau hauv uas lawv thim rov qab. Qhov no tuaj yeem siv tau sai sai, tab sis raws li cov neeg siv, lawv feem ntau tsis meej pem thiab hloov ua kom pom tseeb thaum lawv xav hloov qhov zoom.

Kev tsim kho yog qhov ruaj khov, txawm hais tias nws siv cov yas ntau dua li lwm cov L-series tag nrho cov hlau lo ntsiab muag. Zooming thiab focusing yog du thiab du, ib yam li cov ntaub ntawv nrog tag nrho cov ntau yam. Cov xim dub yeej ua rau lub cuab yeej me ntsis "ste althy" dua li xim dawb Canon EF 70-200mm / 4L lo ntsiab muag.

Lub lens hood uas suav nrog nqi $ 60 yog tias yuav khoom cais. Nws yog me me, tab sis txij li lub lens zoom mus txog 24 mm, nws tsuas yog tsim nyog. Nws muaj cov duab zoo nkauj, uas muab qhov zoo tshaj plaws kev pab cuam, tab sis nws tseem tsis tau zoo heev thaum lub optic txuas mus rau 105 hli. Qhov no yog qhov teeb meem nrog txhua qhov zoom. Ib qho txiaj ntsig ntawm lub lens hood ntiav yog tias koj tuaj yeem ncav cuag nws thiab tig lub lens polarizer. Tsim los siv rau hauv lub koob yees duab puv npo. Lub lens hood ua haujlwm zoo rau lwm yam DSLRs ib yam nkaus, txawm tias tsis zoo txawm tias ntawm 24mm raws li lub kaum sab xis me dua yuav tsum muaj lub lens tob dua kom tshem tawm vignetting.

77mm lim yuav haum thiabrau qee lub lens xws li EF 300mm / 4L, 20-35mm / 3.5-4.5, 400mm / 5.6L, 17-40mm / 4L, 16-35mm / 2.8L, EF-S 10-22mm thiab lwm yam. Thov nco ntsoov tias EF 16-35mm / 2.8L II xav tau 82mm lim. Qhov no tej zaum yuav yog Canon nkaus xwb uas xav tau qhov loj dua. Nrog rau kev txo qis adapter, 77mm cov ntxaij lim dej kuj tuaj yeem siv rau ntawm qhov muag me me. Muaj tseeb, qhov no nws tsis tuaj yeem txhim kho lub lens hood.

Raws li cov neeg siv lus tawm tswv yim, cov txheej txheem focal ntev uas muaj nyob hauv qhov zoo tshaj plaws yog siv rau ntawm lub koob yees duab puv npo. Lub cev APS-C hloov lub lens ib txwm rau hauv tele-zoom, txij li los ntawm 24 hli mus rau APS-C lawv muab tib lub kaum sab xis pom li 35 hli ntawm tag nrho cov ncej. Tab sis Canon EF 24-105mm / f 4L YOG USM khub zoo heev nrog 10-22mm / 3.5-4.5 ntawm 40D hom DSLRs. Yog tias ob lub lo ntsiab muag muaj, tsis muaj leej twg yuav khuv xim tsis muaj 23mm, muaj qhov sib npaug ntawm 16-168mm raws li lub koob yees duab puv.

Kev ua haujlwm

Qhov no feem ntau yog rau tag nrho cov sensors (xws li EOS 5D), tab sis Canon 24-105 f / 4L lens tuaj yeem siv rau hauv lwm cov chaw tsim khoom DSLRs suav nrog EOS 20D, 30D, 40D thiab Digital Rebel series.. Txij li thaum lub koob yees duab nrog APS-C sensor tseem ceeb qoob loo tag nrho cov duab, lawv cov kev ua tau zoo ntawm cov khoom xws li distortion, vignetting, edge sharpness, thiab chromatic aberration yuav zoo dua li cov duab puv puv. Qhov no yog vim APS-C sensor tsuas yog ntes tau "qhov chaw qab zib" hauv qhov chawncej qhov twg feem ntau aberrations qis dua ntawm cov npoo. Tus nqi them rau qhov no yog qhov poob ntawm qee lub kaum sab xis ntawm qhov pom thiab qhov yuav tsum tau ua kom loj cov duab qoob loo los ntawm 1.6 npaug txhawm rau kom tau txais cov duab sib npaug. Qhov no txo qhov zoo tag nrho, xws li luam tawm los ntawm qhov tsis zoo me me piv rau cov loj.

Distortion

Distortion ranges los ntawm nruab nrab chim distortion ntawm 24mm mus rau me me hloov ntawm 50mm thiab mos pincushion distortion ntawm 105mm. Distortion tej zaum yuav tsis pom zoo nyob rau hauv feem ntau cov koob txhaj tshuaj, tab sis yog tias koj qhov kev kawm yog architecture nrog ntau cov kab ntsug thiab kab rov tav nyob ib ncig ntawm cov npoo ntawm tus ncej, nws tuaj yeem ua teeb meem. Distortion tuaj yeem kho tau - Canon tus kheej DPP RAW converter tuaj yeem siv cov kev hloov kho rau RAW cov duab coj nrog 24-105/4L. Thaum tua slides los yog negatives rau cov pa luam ntawv kho qhov muag (uas yog tsis tshua muaj heev, tab sis ua tau), koj yuav tsum zaum xaiv lub lens nrog tsawg distortion. Rau txhua qhov xwm txheej, qhov kev sib txawv ntawm qhov ntsuas yog qhov tseeb ntawm lub neej thiab tuaj yeem kho nrog me me lossis tsis pom qhov cuam tshuam rau cov duab zoo.

Vignetting

Raws li koj xav tau, vignetting yuav pom pom hauv cov duab puv npo thaum lub aperture qhib dav. Ntawm 24mm ntawm qhov siab tshaj plaws aperture, cov ces kaum tsaus tuaj yeem pom, tshwj xeeb tshaj yog nyob rau hauv daim duab nrog lub suab sib xws (piv txwv li, lub ntuj xiav). Vignetting ntawm 50 thiab 105 mm tsis zoo ib yammuaj zog, zoo li ntawm 24 mm, tab sis nws nyob ntawd. Ntxiv dua thiab, nws yuav dhau los ua pom tau thaum tua scenes nrog lub kaum ntse ntse. Teem nws rau f/5.6 zoo heev txo tus nqi ntawm vignetting. Txij li thaum APS-C sensor qoob loo cov duab los ntawm qhov nruab nrab ntawm tag nrho cov thav duab, cov nyhuv no tsis pom zoo ntawm cov koob yees duab SLR, txawm tias ntawm qhov siab tshaj plaws ntawm 24mm. Qee tus tswv APS-C uas twb tau siv lub ntsej muag puv puv thiab tau hloov mus rau lub koob yees duab tsim nyog yuav ua rau muaj kev xav tsis thoob thaum lawv pom feem ntau (yog tsis yog tag nrho) ntawm lawv cov optics pib qhia vignetting.

Tom qab kho cov duab tsis siv neeg, ci ntsa iab ntawm cov ces kaum yuav pom tau. Cov yam ntxwv no tuaj yeem kho qhov txawv txav thiab chromatic aberration tib lub sijhawm. Cov neeg siv nco ntsoov tias thaum luam cov duab loj, tag nrho cov ntawv loj loj txiav tawm ntawm cov ces kaum, vim tsis muaj tus qauv muaj qhov sib piv 2: 3. Yog li ntawd, qhov chaw tsaus ntawm daim duab yuav raug txiav lawm.

Bokeh

Bokeh, lossis tsis pom qhov zoo ntawm cov duab zoo, yog ntau tshaj qhov tsim nyog rau f / 4 lo ntsiab muag, tshwj xeeb tshaj yog nyob rau qhov ntev focal ntev. Cov npoo tawm ntawm kev tsom xam yog me ntsis congested thiab hnyav, tab sis qhov ntawd yog ib txwm zoo rau hom optic.

Lub degree ntawm qhov muag plooj yog nyob ntawm qhov sib piv ntawm qhov deb ntawm lub koob yees duab mus rau qhov kev kawm thiab los ntawm cov ntsiab lus mus rau keeb kwm yav dhau. Tsuav nws nyob ze rau lub koob yees duab dua tom qab, lub bokeh yuav txaus siab.

Txawm hais tias lub lens tsis tuaj yeem sib tw nrog qhov dav aperture lo ntsiab muag, tshwj xeeb tshaj yog EF 85mm / 1.2L, 24-105mm / 4L, ntawm105mm cais cov ntsiab lus ntawm keeb kwm yav dhau zoo heev.

Stabilization

Canon thov tias tig rau ntawm cov duab stabilization muaj nuj nqi tso cai rau koj kom lub shutter ceev 3 zaug. Kev txhaj tshuaj ntawm 24mm ntawm 1/6s yog qhov zoo nkauj thiab txawm tias txog 50% ntawm kev txhaj tshuaj ntawm 1/3s yog qhov zoo. Ntawm 105mm, feem ntau ntawm cov duab zoo tuaj yeem nqa ntawm 1/13s. Tau kawg, kev txhaj tshuaj tsis zoo ib yam li yog tias lawv raug coj los ntawm lub koob yees duab, tab sis meej txaus. Cov nuj nqis no zoo ib yam nrog Canon qhov kev thov ntawm peb qhov kev faib ntxiv. Thaum shooting ntawm xws li qeeb shutter speeds (1/3s ntawm 24mm, 1/13s ntawm 105mm) nws yog ib txwm ib lub tswv yim zoo kom ntes tsawg kawg yog ob los yog peb thav ntawv, qhov no yuav ua rau kom muaj feem tau txais tsawg kawg yog ib tug ntse duab.
