Hi viovanda
" 裂像对焦屏" you mean "Focusing Screen Ef-S...." ??
If it is you question, then all 9 points work with all focusing screens.
As I understand "裂像对焦屏" is not common in canon :)

我50D 用三合一對焦屏... 正! 正! 正!
對焦屏基本上係唔會影響合焦點運作... 反而測光方面長焦有可能會over o左... 自己玩o下就知... 呢個係光學o既原因... 只有自己用m mode或者+/- ev 去就...
