Lens Canon 24-105mm: dib u eegista, caddaymaha, dib u eegista. 24-105mm Canon xeeraan f / 4L WAA USM

Canon leeyahay, oo ay la socdaan ku lenses more dhaqanka f / 2.8 waxaa loo soo koraya L line la lenses f / 4 a. Waxay ka yar, ka jaban iyo xumbo kuwa caadiga ah, laakiin waxay leeyihiin tayo sare leh iyo sifooyinka sida xoog iyo impermeability.

Taxanaha f / 2.8 gashto waxaa ka mid ah sida xirfadda Canon, sida 70-200, 24-70, 16-35 (WAA). F / 4 yihiin dad lagu daydo 70-200, 24-105, 17-40 iyo YAHAY. In dib u eegis this waxaan diirada saari doontaa 24-105mm xeeraan / 4L WAA USM.

Tilmaamo guudmar

Xaqiiqada ah in qalabka waa taxane ah oo L, waxaana dhihi karaa sida ugu dhakhsaha badan siku dhici gacmaha u geliyey. Iyagoo keliya ma aha, sababtoo ah ee giraanta cas ee Geesta hore - tan waxaa ka muuqata in ay xoog iyo isku halaynta. Birta buurta waa wax badan ka yar u nugul in ay xirtaan badan caag ah, ciid iyo qoyaan ka iman doonaan haan marka toogtay halka roob khafiif ah. nooca Ring-Xiinka si sax ah, si deg deg ah oo ku dhow aamusnaan ah diirada kaamil ah. hab la heli karo iyo buuga.

Xeeraan 24-105mm / 4L - Canon gashto, kuwaas oo astaamaha isaga bixiyaan set ganaax of dhererka focal. Malaha xitaa ka fiican tahay 24-70 mm / 2.8L ah. 24 mm bixiyaan a xagal ballaaran run. Labada siku dabooli kala duwan ee caadiga ah ee 50 mm, laakiin model this ayaa sidoo kale waxaa ka mid ah sida sawirka iyo, sida dad badan u yeedhay oo dhererkiisu focal of 80-100 mm. kamaradaha-format Full la xuduudaheedu sida bixiyaan footage u fiican oo ka mid ah "madaxa iyo garbaha". 70 mm 24-70 xaddidaadda ka dhigan tahay in la gashto tani waa ka yar ku haboon images sida.

Intaa waxaa dheer, model this si fiican u saaraysaa Bbc, koox dad ah iyo dhismayaasha. Tani waa mid ka mid ah ujeeddooyinka ujeedada guud, iyada oo aan taas waa ay adag tahay in la sameeyo, iyo cidda aad isticmaali karto si aad kaamil ah vacation. Taageerayaasha of rasaas la model dhererka focal dheer iyo in la siiyo fursad. Dabcan, 105 mm waa ku filan si ay ula Sawiro qabtaan - waxay yeelan doontaa in lagu daro telefotooptikoy 100-400mm / 4.5-5.6L.

Iyada oo miisaanka a of 670 g siku model si weyn u fududee 28-70mm / 2.8, mass ee taas - 950 Si kastaba ha ahaatee, in aanu si fudud ama is haysta.

aperture ugu badnaan waa loo siman yahay si f / 4, dooni xadka ma aha, laakiin ugu yaraan waa joogto in ka badan kala duwan ee zoom oo dhan, iyo qaybsashada oo dhan waa ka wanaagsan yahay ugu lenses zoom in ay xadka sare. Si aad u toogtaan goobaha ISO sare gudaha, in xaaladaha iftiin yar yahay, waxay loo baahan yahay. Laakiin dhanka kale, faa'iido kale oo Canon xeeraan 24-105mm / 4L waa nidaam dhisay-in image xasilinta u ogolaanaya kordhinta ah 3-laab xawaaraha. Sidaas waxa haddii sawir la qaadan photos af badan oo aan WAA at 105 mm in 1/125 sec, laakiin hadda wuu pictures of 1/15 sec wuxuu qaadan karaa. Taasi waa sababta siku haboon toogtay gudaha, gaar ahaan inta lagu jiro maalinta yahay, inkastoo IS waxaa laga yaabaa in aan looga hortago isku dari kara mooshin, kaliya gaadhista gaaban waa inay awoodaan inay soo kabsan karto. F / xeeraan 2.8-optics 24-70, kaas oo stabilizer jirin, ama nepolnoformatny 17-55 dheeraad ah oo ku haboon qabsaday images in xaaladaha iftiin yar yahay waa. Dabcan, gargaarka had iyo jeer iman karaa flash, laakiin waxa ay ku baabbi'in jawiga iftiinka dabiiciga ah.

Marka la gashto waa (la socdaan 70-300 WAA) marka hore u muuqday sanadkii 2005, ka-baarka ugu horeysay xaaladaha qaarkood, xanuunsado tan iyo si kajan ah. design ayaa waxaa si deg deg ah oo go'an, oo tan iyo sanadkii 2006 lenses ayaa la soo saaray iyadoo aan khasaare this.

Optics ka kooban yahay 18 walxood, oo ay ku jiraan mid ka mid Super UD iyo saddex aspherical, sidaasna ay ku kordhiyaan tayada image iyo in la yareeyo Jecaylkaas xitaa marka aperture waa u bannaan yihiin.

Tani gashto for camera Canon gebi ahaanba laga shaabadeeyey, taas oo macnaheedu yahay in gaskets hoosteeda ku siddo diiradda iyo zoom beddelaan, iyo sidoo kale on buurta. Xaaladdan oo kale, ee la soo dhaafay si buuxda wax ku ool ah oo kaliya marka la optics shaabadeeyey qolkii loo isticmaalo. Asal ahaan waa taxane ah oo qalabka EOS 1. Shirkadda Canon in dheeraad ah loo ilaaliyo ku talinaysaa in la isticmaalayo filter UV 77 mm, haddii siku waxaa loo isticmaalaa in roobka.

Tilmaamo design

gashto waa dhammaataan isku dheeli tiran la kamaradaha 40D ama 5d. Wuxuu ma ahan oo khafiifa, laakiin arrin is haysta, iyo raaxo leh si uu u qabto in gacanta. Waxa kaliya ee waa yara users wareer - taasi waa waxa ka dambeeya giraanta zoom iyo giraanta diiradda waxa uu ku yaalaa at hore. lenses kale xirfadeed ee Canon la USM-matoorrada (tusaale ahaan, 20-35, 28-135 WAA, 17-85 WAA) ku kala duwan yihiin oo ay ku yaalaan soo horjeeda. By this, waxaad samayn kartaa si deg deg ah loo isticmaalo, laakiin sida laga soo xigtay dadka isticmaala, ay inta badan wareersan, wuxuuna beddeli diiradda marka ay doonayaan inay wax ka bedesho zoom ah.

design waa mid aad u adag, inkasta oo ay si ballaaran loo isticmaalo caag ka badan inta kale ee taxanaha ah ee la gashto oo dhan-biraha L. Zoom oo diirada waxaa si habsami ah oo aan jerks sameeyey, sida kala duwan oo dhan line ah. Black, dabcan, ka dhigaysa qalab yar oo dheeraad ah "qarsoodi" ka badan lenses cad Canon xeeraan 70-200mm / 4L.

Hood, kaas oo la mid ah, waxaa haboon $ 60, haddii si gooni gooni ah ku iibsaday. Waa wax yar, laakiin sida zoom gashto ilaa 24 mm ah, waa lagama maarmaan. Waa qaab qayb ubax bixiya caymiska ugu badan ee suurtogalka ah, hase ahaatee, ma aha mid aad u wax ku ool ah marka optics la jiido si 105 mm. Tani waa dhibaato oo dhan zooms. Faa'iidada of Dhuunta a-gacmeed waa in ay macquul tahay in ay gaaraan baxay oo u soo jeesan polarizer siku. Loogu talagalay in loo isticmaalo kamarad buuxa. Hood shaqeeyaa ganaax on kamaradaha kale SLR digital, in kastoo aan sida wax ku ool ah, oo xataa meel 24-mm ah, si xagal daawashada yar yar waxay u baahan tahay Dhuunta qoto dheer in laga takhaluso vignetting.

filter 77 mm haboon lenses kale oo gaar ah, sida ku xeeraan 300mm / 4L, 20-35mm / 3,5-4,5, 400mm / 5.6L, 17-40mm / 4L, 16-35mm / 2.8L, xeeraan-S 10-22mm al et. soco in 16-35mm xeeraan / 2.8L II loo baahan yahay filter 82-mm. Waxaa laga yaabaa in tani ay tahay muraayadda kaliya "Canon", taas oo u baahan size wayn. Iyada oo hoos-adabtarada 77 filtarrada mm sidoo kale waxaa loo isticmaali karaa on optics yar. Si kastaba ha ahaatee, haddii ay taasi ku, ma aha mar dambe suurto gal ah si loo soo dajiyo daboosho.

Sida laga soo xigtay war celin user, set ee hadda dhererka focal ku fiican yihiin in loo isticmaalo on camera a jir buuxa. APS-C-jirka jirsado gashto caadi ah in zoom Telefoto, sida 24 mm APS-C bixiyaan xagal la mid ah aragtida sida 35mm a qaab jir buuxa. Laakiin Canon xeeraan 24-105mm / f 4L WAA USM aad u wanaagsan la 10-22mm / 3,5-4,5 at nooca SLR ku 40D. Haddii ay jiraan labada ujeedo, ninna ka xumaan doonaan maqnaanshaha 23 mm, isagoo u dhigma of 16-168 mm ka barta of view of camera dhererka-buuxa ah.

wax soo saarka

Asal ahaan halkan ku yidhi timaado in shidma jir-buuxa ah (sida 5d EOS ah), laakiin gashto Canon 24-105 f ah / 4L kaloo loo isticmaali karaa in kamaradaha SLR digital kale soo saaraha, oo ay ku jiraan EOS 20D ah, 30D, 40D oo taxane Digital Mucaaradka. Tan iyo kamaradaha la APS-C-shidma, dhab ahaantii, ka gooyay image mooshin-buuxa ah, waxqabadkooda la xidhiidha waxyaabaha sida dhalanrog, vignetting, macaamiloon qarkiisa iyo Jecaylkaas chromatic, ayaa laga yaabaa inuu ka sii fiican ka badan dhererka buuxa. Tani waa sababta oo ah shidma APS-C qabsatay ah "kaalinta macaan" ee xarunta of jir ah, halkaas oo inta badan aberrations waa ka hooseeya at geesaha. Qiimaha waayo, taasu waa khasaaraha of xagal qaar ka mid ah aragtida iyo baahida loo qabo in la kordhiyo image ku yaryihiin by 1.6 jeer, si aad u hesho size ee u dhigma ee sawirka. Tani waxa ay yaraynaysaa tayada guud ee print sida a diidmo yar marka la barbar dhigo weyn ee.

dhabtii

kala duwan Distortion ka dhalanrog foosto dhexdhexaad at 24 mm in isbedel aad u yar kala duwan ee 50 mm iyo dhalanrog a pincushion jilicsan ee 105 mm. Distortion, malaha ma noqon doonaa mid aad dareemi on darbo ugu caadiga ah, laakiin haddii mawduuca waa naqshadaha leh tiro badan oo ah khadadka joog iyo jiif on cidhifyada jir ah, waxay noqon kartaa caqabad ku ah. Distortion, dabcan, waa la sixi karaa - gaar DPP cayriin-Converter Canon waa inay awoodaan inay si toos ah u codsan la rajeenayo in the-cayriin image, helay iyadoo la kaashanayo of 24-105 / 4L. Marka toogtay slide ama negative for daabacaadda indhaha caadiga ah (taas oo ah mid aad u badneyn, laakiin ay suurtogal tahay), waa in aad u badan tahay dooran gelis la dhalanrog yar. Xaaladaha kale oo dhan, dhalanrog ee miisaanka waa xaqiiqo dhab ah oo ka mid ah nolosha iyo la sixi karaa iyada oo saameyn yar ama la dareemin, tayada image.

vignetting

Sida mid ka fili lahayd, on the images size-full isticmaalaya aperture balaadhan-furan noqdo vignetting dareemi. 24 mm at aperture ugu badan waxaa laga arki karaa geesood madow, gaar ahaan sawirka la midab direyska (tus, samada buluugga ah). Vignetting 50 iyo 105 mm ma xoog badan yahay sida 24 mm, laakiin waa. Mar kale waxa uu noqonayaa dareemi markii rasaas goobaha la xaglo uniform. Rakibaadda ee f / 5.6 si weyn u yaraynaysaa saamaynta vignetting. Tan iyo furta oo APS-C dhimaysa baxay image ee xarunta jir buuxa, saamaynta on unugyada muraayad oo kale waa mid laga samri, xataa furitaanka ugu badan ee diaphragm ka ilaa 24 mm. Milkiilayaasha Qaar ka mid ah APS-C, taas oo uu horey u riyaaqay dhererka buuxa lenses iyo wareegeen kaamirooyinka ku haboon ka filan karto la yaab leh marka ay arkaan in inta badan (hadii aan dhan) ee optics ay bilaabeen in ay muujiyaan vignetting.

Ka dib markii la saxo si toos ah image uu noqdo xagal nalalka la arki karo. function Tani waxay sidoo kale waqti isku mid ah si loo saxo karo dhalanrog iyo Jecaylkaas chromatic. Xubnaha la soco in dhammaan tirada caadiga ah ee rukummada cut warqad markii daabacaadda images weyn, tan caadiga ah ma uusan u dhiganta saamiga 2: 3. Sidaa darteed, meelaha mugdiga ah ee sawirka la jaray doonaa hab kasta.

Boke

Boke ama tayada image defocussed, optics ee f / 4 badan istaahilo, gaar ahaan dhererka dheer focal. geesaha Unfocused iyo in yar oo af badan oo naxdin, laakiin waa caadi optics sida.

engegnaantiinna aawadeed waa si xoog leh ku tiirsan ratio of masaafo ka camera si mawduuca iyo wax ay u asalka. Inkasta oo waxa uu ku yaalaa u dhaw in ay kaamirada ka badan bokeh asalka ku farxi doonaa.

Inkasta oo siku ma leh lenses aperture badan oo la tartami karta, gaar ahaan xeeraan 85mm / 1.2L, 24-105mm / 4L, 105 mm ku filan si fiican u kala dambeeyaan ka soo jeeda.

xasilinta

Canon sheegayaa in mid noqoshada ee shaqada image xasilinta kordhin kartaa shutter ah 3 jeer. Pictures leh 24 mm-dib u 1/6 iyadoo si cadaalad ah oo nadiif ah oo xitaa ku saabsan 50% ka mid ah tallaalada qaaday at 1/3 waa uun kuwa Liibaanay. Fogaan ah 105 mm inta badan images wanaagsan la samayn karaa at 1/13 sec. Dabcan, looxyadii Isku mid ma aha arrin u Cadaaday sidii iyagoo loo qaaday la Maala ah, laakiin si cad oo ku filan. tirooyinka waxay la hadal Canon ah saddexda qaybood oo dheeraad ah. Marka la xawaare shutter sare sida lagu qoro (3.1 illaa 24 mm, 1/13 mm in 105) mar walba waa fikrad fiican in lagu soo qabto ugu yaraan laba ama saddex Click here to, waxaa aad bay u weynaan doonaa fursadaha helitaanka ugu yaraan hal image af badan. The boqolkiiba hal dhibic oo dhan. Sawiradaas waxaa loo sameyn doonaa, si fiican fursad si uu u sameeyo sawir wanaagsan.

In ka matrices APS-C keeni waxa ay u muuqataa xitaa si fiican sida rukummada keenin oo shidma jir buuxa arkaa kaliya qaybta dhexe ee images la aberrations yar.

Jecaylkaas chromatic

In opinion ee milkiilayaasha, ka aberrations chromatic yihiin xadka la aqbali karo dhamaan dhererka focal. Aad fringing midabka yar arki karo on cidhifyada jir oo dhan, laakiin haddii aad u soo gani in hab cayriin, edbinta si toos ah in DPP this hagaajin kartaa, ama waxaad isticmaali kartaa software tafatir sida Photoshop. heerarka dhalanrog at 24 mm dhigma 24mm / 2.8, inkastoo laga yaabo in wax yar ka yar.
