Focusing Tip: Zoom In (Basic)

If you have a zoom lens and your camera is having difficulty focusing, try to zoom in to get a larger image, half-press the shutter to lock focus on your subject, then zoom out. Even though you zoom out, the focus will be maintained so long as the distance between the camera and the subject remains constant (this characteristic of modern lenses is called "confocality").  You can try this out to confirm :)

    Well, I know this photographer who thought a more expensive tripod would make a difference when ambient is so dim and flash is being used... :)

    Great tip! I would never had thought of this. Thanks! Btw, I just found your blog last night and have been going thru the "Index of Articles." Great information. Thank you so much for creating the blog. I've learned quite a few things so far and I'm only a fraction down the index. :)

      Well I have good news for you. The index has actually not been updated in over a year. So even after you go through the index, there are still many more articles left to read :D
