Also what really helps is putting a large LCD screen on your ridge but if it's a handheld ridge it can get too heavy easily. I've been sweating like a pig and coming home with back pains when shooting like that. The AF100 has a great focus assistant on the LCD screen that puts red edges around everything that's in focus. And no you can't trust your model to help you with this, is there anything models can help a photographer with apart from being no-limit sluts in front of cam? I don't even want them to do the dishes because they'll use half your bottle of cleaning product for cleaning three plates and two pans :-)
