Still is not recommended, we can talk in circles all you want but the reality is that the focus range has a sweet spot especially in a narrow depth of field, if you dont measure it you run the risk of getting it on the soft part of the focus no matter how much practice you might have, you are not a robot to preform the same all the time. monitors are a great tool but they are not to be trusted with focus even if they have focus assist tools, people that use measuring tape and lasers have consistently preform better focus pulls then monitor watchers. monitor watcher take so many tries and they take valuable time that could be spent in other shots but for some reason they think is faster just doing it like that instead of spending 5 secs to get the right measurements in the first place. the numbers on the lens are there for a reason use it !!!!
