For $150, just buy it.
I just received mine Friday, unboxed it, screwed it on to my 60D and rushed out the door to pick up my baby girl and then head over to my wife's work outing. The sun had already set behind the trees at the park (but not set on the horizon) when I snagged this pic (this is literally a snap shot and that's it - didn't have time or space to maneuver for anything more significant as I was SURROUNDED by people behind me and my wife was 2 seconds from handing me my little girl to take part in a 3-legged relay race)
**I just realized upon previewing this post that CR downsizes pics. So, just copy the url and paste for 1200 pixel wide versions of these pics**
That was shot at f/2.8, 1/200, ISO100 from a few feet away. PP'ing was all done in DPP and consists of DLO correction as well as other lens aberration corrections, sharpening @ 4 and RGB sharpening @ 125.
What's pretty amazing (to me anyway - perhaps y'all disagree) is the 100% crop
Color me impressed!
I managed to pick mine up for $142 (thanks to a heads-up on this site) from Adorama right as the rebates went into effect. I haven't spent $142 more efficiently since I took my first picture.
Also, I've just used DLO for the first time today. Anyone have any recommendations for a standard setting for the slider bar? I think this one was at 65. Thanks!
