本人已有老花,很多時要自動對焦時都有問題, 我用5D, 是否可裝裂象對焦呢, 我見到有裂象對焦的配件,不過唔識裝,師兄們有甚麼建議呢?

調一下屈光度.

自動對焦無問题,若要手動對焦可先把接目鏡旁的屈光補償推向+號以配合自己的老花度數,不必換對焦屏.

solution 3: change camera
u may also consider change to a camera with liveview, which can be used to in manual focus, I use a 1.4X with a Sigma 80-400OS (no AF) with 5D2 on a tripod to give very good manual focus.
