Yeah. I debated 2-stop vs. 3-stop and decided on the 3-stop because, 1) the CPL provides ~2 stops, why duplicate that with an ND?, 2) looking at the number of stops I needed with f/1.8 on a bright day, 3 stops would have been enough (especially now that I have an extra stop of shutter speed), and 3) I could always stack the CPL, since that's a slim mount, for ~5 stops.


I looked at the Vari-ND, but decided that for cost relative to likely amount of use, and the desire to go to greater than 8 stops for some really long daytime shots (I have actually stacked my 0.9 and 3.0 filters on occasion), I'd stick with standard NDs.
