Here's the advice Bryan Carnathan gave me when I asked him the question concerning a trip to the Southwest;

The screw-on versions are extremely limiting. Lee is one example. My guess is something in the 2-stop range is going to be useful."
<p class="MsoNormal"]<span style="font-family: 'Calibri','sans-serif'; color: black; font-size: 11pt;"]I looked at the Lee product at a shop and they seemed to beinfinitely adjustable and quality materials.....no, I didn't purchase...I decided to go w/a 10-22 lens instead.
