Copy/paste from the birdforum thread about them.OwenM: What is the difference between the DCF ED 8x32 and the SP one?
"I know there's some additional ED element/s over the SP somewhere in there, and a difference in the coatings. I hope to see a little more color saturation, and the elimination of what little off-axis CA there is. That seems realistic. Based on some of the reviews it might be a tad brighter?"
btw:
ED=extra low dispersion glass(for eliminating CA)
CA=chromatic aberration, basically color fringing on high contrast objects
There don't seem to be many online reviews of the EDs, and I've never seen one in person, so I won't actually know firsthand 'til later this week.
Cheapest price on Amazon is $669 right now for the ED:

The SP is $341 shipped:

You can always return them if you don't like them. Also, these prices/dealers will continually fluctuate.
I'm still new to this stuff, but it's as addicting as any other hobby I've had
