Now the problem occurs, that there is not, one lens hood length good for all lenes. On a 24mm wideangle , there needs to be a short hood. So as not to intrude into the image (seen thru the lens). Perhaps you've all seen dark corner edges on a print, where the lens sees the hood or shade.
On a longer lens or tele- zoom a long hood is desirable say, 4 to 6 inches covering in front of the lens.
So you can see the zoom lens maker's dilemma. how long can you make a hood . It has to be short for the wideangle portion and never a useful length for your tele. In-order to eliminate glare or flare.
You can compansate by holding your free hand (or piece of paper) over the lens while shooting in open sun. Or find a second longer hood for the times you shoot with the tele 200.
