當我加了之後點解我用景觀器會變得好暗，是不合用還是需要調教??
但我用canon450D kit加上去又冇事呀......求高手教路..

"而用在cannon就是全開光圈.所以看來沒有變,但都是控制不到光圈.只可用全開光圈影." <==== WRONG

if using CANON, u can adjust the aperture by
1. set to A mode
2. set the lens aperture u required
3. PRESS the depth-of-field preview button (don't release)
4. while press the depth-of-field button, unmount the EF lens by pressing the lens release button

The required aperture will be set on the EF lens

樓主用的extension tube，
係冇任何的方式去控制光圈、對焦，要自己想辦法。

Nikon係機械方式控制，一開始係最細光圈；Canon係電磁式，光圈一開始會係放到最大。
所以裝上機身，兩間品牌的VF睇到的光度會好唔同。

唔想搞太多野，Kenko Extension Tube 會係唔錯的選擇。

"燒機燒鏡" will not occur as I have tested many many times on cheap cheap SSP extension tube
