| Re: AF or MF?
. . . and the same here. AF for flying birds but MF for macro or questionable backgrounds.
Slightly different glasses problem. Only need reading glasses but have to put them on to find macro subjects then take them off to get a sharp manual focus. Trouble is what to do with the glasses when they aren't on my nose. In a trouser pocket they get bent as I don't want to keep opening and closing a case. Too often I just put them on the ground and step on them or they fall into the undergrowth and I can't find them again. Tucking into my collar works best but they can still fall out when I bend over. Only take cheapie specs with me now!
But back to AF/MF. I find that while AI servo works fine for flying birds it can tend to keep 'hunting' when used on closer depth of field work so I switch to One Shot then. Variable focus problems can be common when using Converters.
For close work a tripod makes all the difference, and subjects blowing around in the wind can be problematic.
Poor contrast in the background can also cause problems.  |
