...the default "step" parameter is too low ... switched it to 40 and there with every click of the zoom button, the effect were more noticeable...What are these "steps" anyway? Do they represent centimeters or inches?
For very close Macro work like the SX20 is capable to achieve...meaning that the object is only 1 or 2 centimeters away from the front of the lens, I have found that I need to lower the value to about 10 or 15. Having said that, if I were to photograph something much farther (like I was trying to do in my first test shots) it seems that this is when the Steps need to be higher.
