-- nah, I just like working with the EV readings, and after taking a few readings I can pretty much figure out my exposure EV and placement/fall of important areas before setting the exposure EV on the dial to select the corresponding f/stop and exposure combo I want to use. So having a visual aid of the Zones on the dial just cluttered it up for me. But I can see why others would like the sticker.
I have the Pentax Digital, with a non-digital Pentax Spot Meter V as my back-up. After years of using a Luna Pro and having to fix its needle occasionally due to rough use, I wanted a meter with less moving parts...and the digital readout is easy to see in low light situations. I have no need for a meter with memory or averaging (or metering flash), so I love the simplicity of the Pentax Digital.
