小弟剛買了部cannon 450d單反,冇鏡.

現在想買支a16,因為冇錢,想買2手

但係又乜都唔識,所以想問下各位師兄買時要注意些甚麼

點樣check支鏡好唔好有冇問題呢?

當然,我會盡量買些有保養的2手鏡,始終有保障些.

Assuming u have brought your camera

1. check the gold finger of the lens rear part (should not be "花")
2. point to light source, remove the rear & front caps, check lens inside (should be no much dust particles, can have some tiny bubbles inside the glass)
3. mount the lens, check AF, point to a newspaper 45° & shoot at the largest aperture (u can have better & detail check by the following method at home:

4. check aperture, use M mode or A mode, press the step down button, change A value, there image viewed in the viewfinder becomes darker as the A value increase

咁首先就係睇下支鏡個外觀，睇下有冇d大傷

之後可以轉下個變焦環and 對焦環 (如果唔係全時要set 反mf )會唔會過緊

** 最重要 之後搵d lighy sourse 照入去睇下有冇mo ，一路睇要一路轉個變焦環睇下each 鏡片有冇mo

之後睇下有冇霞

再上反個body 影下

用下af 睇下有冇問題

有保果d就睇反d單齊唔齊，同鏡身 no. 係咪一樣

chexk下d配件齊唔齊

應該ok了


有錯請其他ching指正

多謝2位師兄.

不過原來買鏡仲麻煩過買機的

仲難過check 機...

咁色又點睇架?有的人話支鏡的色有問題

點樣先知/乜叫色有問題呢?
