我部傳統SLR當望入Viewfinder裡面有一點黑色塵, 試過吹個 Reflex mirror 都沒用... 請問:
1. 對影相有沒影響
2. 如果拿去Canon抺, 要幾錢 (已過保用)
3. 有沒其他可行方法

已過保用又唔會影響影像質素,得果一點黑色塵咪當睇唔到算囉.

You can try to clean the focusing screen, just following the instructions on how to replace focusing screens to take out the focusing screen for cleaning.

If the dust is in viewfinder, you must bring it to Canon for cleaning.

However, as gaiuswong said, it doesn't affect image quality for both cases.

唔係隻隻機都有得可以自己換對焦片架,300d已經唔得,如果點塵響對焦片裡面都冇乜計.

[rickywck]

Focusing screen of 300D can be easily taken out. Please follow the instructions on how to modify 300D to use split screen focusing screen.

A lot of SLR/ DSLR would encounter this problem.

Relax, it won't hurt.
