For many years I only ever used my manual focus OM system. For the past few years I have experienced nothing but frustration from the automatic focus of the cheap point and shoot digital I adopted. Now, contemplating getting a MFT camera I have been reading around trying to understand when and how a properly implemented AE system might be useful. (I'm wondering whether I will be wanting any native lenses apart from the 20/1.7 pancake.) I had to laugh at this article 5 Situations When Manual Focus is Better than Auto Focus so thought I might open it for discussion. Reading the article, I am struggling to think of any situation that would not fall under at least one of the points listed in that article . I would have thought moving targets would be a prime instance as these were always amongst the more challenging ones for me with manual focus... but apparently not! So, those of you who can competently manually focus -- when do use AE?
