Personally I do struggle with manual focus but if I put a bit of time in I can get it about right - for me it's a matter of tripod mounting the tripod and using liveview (at 5x mag) to check the focus is bang on. Assuming you are looking for a wide lens for landscape work you should be fine - short focal length coupled with long distance to subject gives good DOF so you can get away with a bit more.
