老蛙MFTArgus18mmf0.95APOshuomingshuzhongyingban鏡頭使用說明書手冊

一：前言真誠地感謝您選購LAOWAMFTArgus18mmf/0.95鏡頭。此鏡頭是針對MFT畫幅系統(tǒng)大光圈鏡頭，最大光圈F0.95，采用內(nèi)對焦設(shè)計(jì)，有級無級可切換光圈，低呼吸效應(yīng)，更傾向于視頻拍攝。！為了操作上的安全，使用本產(chǎn)品前請務(wù)必詳細(xì)閱讀使用手冊與注意事項(xiàng)，并將手冊放在需要時容易取得的地方。如遇到不能解決的問題請通過售后電話獲取技術(shù)支持。二：主要特色Argus系列采用內(nèi)對焦設(shè)計(jì)，內(nèi)對焦是現(xiàn)代鏡頭主流設(shè)計(jì)結(jié)構(gòu)，可以實(shí)現(xiàn)多組浮動匹配對焦，可矯正因距離變化產(chǎn)生的各種像差等，實(shí)現(xiàn)無限遠(yuǎn)和近距離均能優(yōu)質(zhì)成像。內(nèi)對焦的設(shè)計(jì)，也能在惡劣環(huán)境下盡量避免進(jìn)灰的情況。內(nèi)對焦因長度不變，拍攝視頻時不會干擾遮光斗，UV等配件，也不會干擾模特的注意力。內(nèi)對焦通過組間間隔補(bǔ)正，實(shí)現(xiàn)了低呼吸效應(yīng)，適合照片領(lǐng)域的同時，也比較適合視頻創(chuàng)作。2、鏡頭采取輕量化設(shè)計(jì)，大小僅有φ80.*83mm，重量500g，搭配在M4/3畫幅機(jī)身上使用，體積小巧，輕便攜帶。3、最大光圈F0.95，大光圈帶來的淺景深的拍攝效果，更加突出拍攝主體，同時在低照度的拍攝環(huán)境下，可以采用更低的感光度，讓畫面更加純凈。4、鏡頭采用有級無級光圈設(shè)計(jì)，在視頻拍攝過程切換光圈畫面沒有明顯的明暗變化，光學(xué)設(shè)計(jì)優(yōu)化了鏡頭的呼吸效應(yīng)，較低的呼吸效應(yīng)，焦點(diǎn)切換更加自然順暢。5、鏡頭由8組14片鏡片組成，包含2枚異常分散玻璃、1枚非球面鏡片和4枚特殊高折射玻璃的結(jié)構(gòu)帶來的高素質(zhì)成像。外有全金屬材料制成的機(jī)械結(jié)構(gòu)，保障了鏡頭長期使用的耐用性。三、注意事項(xiàng)切勿自行拆解、修改或改裝。當(dāng)產(chǎn)品由于外力原因破損，切勿觸碰外露部分或破損邊緣處。切勿放置于直射陽光下、封閉車輛中或其余高溫處，否則過高的溫度會使鏡片和其他部件產(chǎn)生伸縮變形。不使用鏡頭時，請將鏡頭前蓋蓋上或置于沒有陽光照射處。凸透鏡反射出的光線可能會聚集在附近物體上，導(dǎo)致發(fā)生火災(zāi)。在逆光拍攝時，切勿將太陽置于畫面中心，應(yīng)該使太陽充分偏離畫角，否則陽光會在相機(jī)內(nèi)部聚集并導(dǎo)致火災(zāi)或灼傷眼睛。在使用相機(jī)內(nèi)置閃光燈拍攝時，由于鏡頭本身會遮擋光線而產(chǎn)生漸暈，因此建議您使用外設(shè)閃光燈拍攝。長期使用保養(yǎng)注意事項(xiàng)避免觸摸鏡頭表面，應(yīng)用專用鏡頭布或氣吹去除鏡頭表面的塵埃，不使用鏡頭時，應(yīng)將鏡頭蓋蓋上。使用鏡頭紙或鏡頭布清潔時,以螺旋的方式從中間向外擦拭鏡頭上的污垢以及指印。鏡頭從寒冷的環(huán)境突然轉(zhuǎn)移至溫暖的環(huán)境時，鏡頭的外部以及內(nèi)部鏡片將會凝結(jié)水霧，所以在轉(zhuǎn)移時應(yīng)采取防潮保護(hù)措施。四、各部件名稱1.遮光罩2.遮光罩安裝標(biāo)記點(diǎn)3.濾鏡（鏡頭蓋）安裝螺紋4.對焦環(huán)5.距離刻度6.景深指示刻度7.鏡頭安裝標(biāo)記五、使用說明鏡頭安裝取下鏡頭后蓋。將鏡頭卡口上的安裝標(biāo)記⑦對準(zhǔn)相機(jī)座圈上的對應(yīng)標(biāo)記，隨后將鏡頭插入機(jī)身座圈，根據(jù)所購買卡口的安裝方向旋轉(zhuǎn)鏡頭，直至咔嚓聲鎖緊鏡頭。安裝時請不要用力過猛，以免導(dǎo)致卡口損傷。鏡頭拆卸關(guān)機(jī)后按住相機(jī)上的鏡頭釋放按鈕，依照所購買卡口的安裝方向反向旋轉(zhuǎn)鏡頭，隨后將鏡頭從座圈中拔出。裝上鏡頭后，請嘗試旋轉(zhuǎn)鏡頭確認(rèn)是否已將其固定在相機(jī)上。遮光罩裝卸將遮光罩上的安裝標(biāo)記②對準(zhǔn)鏡頭上的遮光罩安裝點(diǎn)，然后順時針旋轉(zhuǎn)遮光罩，直至鎖緊末端為止。如要拆卸遮光罩，按相反方向旋出即可。安裝遮光罩可減少強(qiáng)光并保護(hù)鏡頭前部元件。安裝某些濾光鏡后，您可能無法再使用遮光罩。若不使用遮光罩時，可將遮光罩反向安裝于鏡頭上。利用閃光燈拍攝時。遮光罩可能遮擋住光線而造成影像上的漸量現(xiàn)象。所以在使用相機(jī)閃光燈或使用高度不夠的外置閃光燈時,請拆卸遮光罩后再進(jìn)行拍攝。對焦此款鏡頭是全手動對焦鏡頭，合焦時，緩慢旋轉(zhuǎn)對焦環(huán)④，直至合焦。不要過猛過快地旋轉(zhuǎn)對焦環(huán)，避免用力過度損壞對焦環(huán)部件。鏡頭上的距離刻度⑤與景深刻度⑥是出于指導(dǎo)目的。實(shí)際焦點(diǎn)與景深可能同刻度標(biāo)記稍有不同。如需要非常精確的對焦，請?jiān)诠潭ê孟鄼C(jī)位置的情況下使用最大光圈對焦，對焦完成后再旋至所需要的光圈值。為了對焦的方便性，請開啟相機(jī)內(nèi)的峰值對焦功能(視所使用相機(jī)功能而定)。光圈使用光圈在鏡身上調(diào)節(jié)，采用了有級無級光圈設(shè)計(jì)，光圈切換沒有段落感，根據(jù)拍攝環(huán)境和與所需要的景深，轉(zhuǎn)動鏡身光圈環(huán)來選擇對應(yīng)的光圈，拍攝前建議檢查光圈數(shù)值，以免誤觸改變拍攝參數(shù)。由于此鏡頭無CPU數(shù)據(jù)，無法記錄光圈參數(shù)。對焦方法一：峰值對焦1、開啟機(jī)身峰值對焦選項(xiàng)，峰值顏色選擇為紅色或常用顏色，峰值選項(xiàng)為低。2、通過取景器或開啟LiveView（實(shí)時取景）功能觀察畫面，通過峰值來觀察對焦點(diǎn)。3、轉(zhuǎn)動對焦環(huán)對物體進(jìn)行精確對焦。對焦方法二：放大對焦先構(gòu)定拍攝畫面，在通過取景器或開啟LiveView（實(shí)時取景）功能觀察畫面的同時，轉(zhuǎn)動對焦環(huán)，構(gòu)定拍攝畫面后，通過按鍵或者雙擊屏幕將對焦點(diǎn)放大，轉(zhuǎn)動對焦環(huán)直至合焦。建議：由于F0.95光圈景深很淺，拍攝的過程中建議使用腳架和設(shè)置安全快門來保證畫面穩(wěn)定性。對焦建議使用峰值和放大相互結(jié)合的對焦方式，保證焦點(diǎn)畫面的銳利。規(guī)格表產(chǎn)品規(guī)格鏡頭名稱MFTArgus18mmf/0.95APO畫幅M43焦點(diǎn)距離18mm光圈范圍F0.95-11視場角61.9°鏡頭結(jié)構(gòu)8組14枚（1枚非球面鏡片、2枚ED鏡片、4枚特殊高折射玻璃）光闌葉片9片最近攝影距離（物像距離）0.2m最大放大倍率0.15倍合焦驅(qū)動方式手動（MF）濾鏡尺寸Φ62mm鏡頭尺寸約φ80mm*83.35mm重量約500g（不含前后蓋）卡口M43PrefaceThankyouverymuchforpurchasingLAOWAMFTArgus18mmf/0.95lens.Thisisanultra-fastf/0.95lensforMFTcamerasystemswhichfeaturesaninternalfocusingdesign.Thislensissuitableforshootingvideowithasteporsteplessswitchableapertureandminimalfocusbreathing.!Readthisoperationmanualcarefullytofamiliarizeyourselfwithitscontentsandensurethatyoucanoperatetheproductproperly.KeeptheInstructionManualinasafeplacewhereitcaneasilybereferencedwheneverrequired.Ifyouarestillunabletosolvetheproblembyreadingthemanual,pleasecontactourafter-salesserviceforfurthertechnicalsupport.FeaturesTheArgusrangefeaturesaninternalfocusingdesign,whichisthemainstreamphotographiclensdesignofmodernlenses.Thislensemploysmultiplegroupsoffloatingmatchingfocus.Itworkstocorrectanyaberrationsandtoachievecornertocornersharpnessatallfocaldistances.Thedesignoftheinternalfocuscanalsobeintheharshenvironmenttoavoidasmuchaspossibleintothecaseofgray.Thephysicalsizeofaninternalfocusinglensdoesnotchangeduringfocus.Itisusefulforshootingvideoswhenusingfiltersoraccessoriesmountedonthefrontofthelensthatmayrequirecarefulalignment.Theinternalfocusingdesignachievesalowbreathingeffectbyinter-groupintervalcorrection,whichissuitableforthephotoshootingwhilealsobeingmoresuitableforvideoshooting.Thislensisdesignedwithlightweightandmeasuresonly80mmindiameter,83mmlongandweighs500g.Itiscompact,convenienttocarryandcanbepairedwiththeM4/3framebody.Themaximumapertureofthislensisf/0.95.Afastaperturebringsashallowdepthoffieldformoreprominentshotsofthesubject,andatthesametime,youcanusealowISOinlow-lightshootingenvironmentsforapurerpicture.Thelensemploysasteporsteplessaperturedesign.Changingtheaperturewon’tbringobviouschangesinlightduringthevideoshooting.Theopticaldesignoptimizesforalowerbreathingeffectandfocusesswitchingbecomesmorenaturalandsmooth.Thelensisconstructedof14elementsin8groups,including
