Lub projector tau nruab nrog lub lens 85mm f/2.8, tshem tau yooj yim los ntawm lub projector nws tus kheej (tsis muaj qhov yuav tsum tau muab sib dhos). Yog li kuv txiav txim siab hloov pauv nws mus rau 85mm lub lens rau kuv lub Pentax K5 lub koob yees duab, siv lub tshuab txuas hluav taws xob polypropylene txuas (uas tso cai rau tsom mus rau lub ntsej muag) thiab K-M42 adapter (txuas lub lens ncaj qha rau lub koob yees duab).

Kauj Ruam 2: Kauj Ruam 2: Hloov Tube

Ua ntej tshaj, yuav lub raj txuas nrog hydraulic, uas yuav ua lub lens. Hauv Ltalis DIY khw: txheeb xyuas cov khoom ntawm no.

Txhawm rau hloov lub raj, Koj yuav tsum txiav ob sab ntawm lub raj (saib cov cim liab ntawm daim duab peb). Xa mus rau daim duab thawj/thib peb:

1. Ua qhov no thawj zaug! - Ntawm sab xis ntawm lub raj, koj yuav tsum tshem tag nrho cov ntsia hlau ib feem. Kuv siv lub hacksaw (daim duab ob) los ua txoj haujlwm, thiab tom qab ntawd kuv ua tiav cov ntug los ntawm kev hlawv qhov tsis zoo nrog lub teeb;
2. sab laug ntawm lub raj (qhov tsawg tshaj plaws hauv txoj kab uas hla) yog zoo li cov kab sib dhos. Yog tias koj muaj Heidosmat, koj yuav tsum txiav ob lub nplhaib kawg, tab sis yog tias koj lub Lens luv dua/ntev dua, koj yuav tsum ntsuas qee qhov ua ntej, thiab txiav lub raj kom haum.

Daim duab kawg qhia pom qhov kawg.

Kauj Ruam 3: Kauj Ruam 3: Kaw lub Adapter Nplhaib

Txhawm rau txuas lub raj mus rau lub koob yees duab Kuv tau kaw "M42 rau K adapter nplhaib" rau lub raj nws tus kheej. Tau kawg, qhov no haum rau Pentax K mount, tab sis yog tias koj muaj lwm lub koob yees duab koj yuav tsum nyeem kab lus no los ntawm Wikipedia ua ntej (vim tias tsis yog txhua lub koob yees duab tuaj yeem hloov kho tau yooj yim) thiab tom qab ntawd sim ua kom tau lub adapter zoo rau koj lub koob yees duab.

Ntau npaum li K mount tau zais, nco ntsoov tias muaj ntau qhov sib txawv M42 rau K adapters (saib daim duab thawj). Yuav ib lub adapter nrog lub hauv paus loj, uas ib txwm pleev xim dub. Koj tuaj yeem pom nws ntawm eBay los ntawm kev nkag mus tshawb hauv qab no: "m42 k adapter ring". Tom qab ntawd:

1. Kua nplaum lub nplhaib ntawm sab xis ntawm lub raj (qhov loj tshaj hauv txoj kab uas hla), siv cov kua nplaum chloroprene. Chloroprene kua nplaum yuav tsum tau muab tso rau ntawm ob sab (lub nplhaib thiab raj) thiab tom qab 10-20 feeb ob qhov chaw yuav tsum tau nias ua ke … ntau dua koj nias, ntau qhov vuam yuav zoo, yog li nias !!!
2. Thaum lub nplhaib nyob hauv qhov chaw, ua kom sov cov kua nplaum kub thiab tso ib txheej tuab ntawm cov kua nplaum nyob ib ncig ntawm lub nplhaib, cia cov kua nplaum lim los ntawm qhov sib txawv nruab nrab ntawm lub nplhaib thiab lub raj.

Qhov kawg tshwm sim hauv ob daim duab kawg.
