can someone explain how that works? obviously the the photographer has to know which was up to holdthe camera, and some basics of composition, etc but if u'r trying to capture birds in flight, a slow AF will not get you good result, no matter how good the photographer.
Nonsense. For one thing, there is always MF, not just for the "olden days", but as a viable way of increasing ones odds of success in certain cases even today. The better photographers know when those cases are. But they also know when to use AF-S versus AF-C, they know when to select focus points versus use the center point only versus let the camera select. When selecting a focus point, they are good at tracking the subject in the viewfinder and keeping it within range of the selected focus points. They know all about pre-focusing (manually or using AF) and when to employ it and have their cameras set up to make this easier, and similarly for using Quick Shift.
And that's just focus - probably about 17th on the list of important things in differentiating great from average photography. Getting past focus but on to the
much more important stuff, the better photographers know where and when to position themselves for the best shots, and the patience to actually do this rather than just shooting from the hip. They have the necessary skill to pan shots when appropriate. They have a feel for the best moments to snap the shutter but also make effective use of burst shooting where appropriate. They understand how to set exposure in the most appropriate way for the situation, and they tend to have good eyes for composition. They know how and when to "create" moments when necessary as opposed to just waiting for them to happen - but they also have a good sense about when they will happen and are prepared for them. They recognize good lighting when they see it, but know how to modify it or otherwise adjust when necessary. They know what scenes won't end up being worth photographing, and they know how to edit their own shots to present only the best. They know how to make effective use of PP to best present the selected shots according to their own creative vision.
I could go on and on and on.
a poor quality lens will not get you sharp photos, how ever good your skill?
This is of course true to some degree, if the lens is
really poor. But the question really is, just how good does the lens have to be to get good results? The basic DA "kit" zooms are considered by many to be only so-so at best, and yet there are professional (and not so professional) photographers out there producing amazing results with them.
