Buying Good Photos

Liz and I got invited to the Oracle booth again this year for the Chicago Airshow.

I took this photo with my Sigma 170-500mm lens.  I'm quite happy with how well it performs.  When I was evaluating this lens, I compared it to a Canon Professional "L" Series 100-400mm lens that cost $1500!  The Canon was a slightly better lens -- slightly sharper and better in low-light conditions -- but I decided that my amateur use couldn't justify the cost.

I don't think the photo is that great.  It's fine technically (thanks to the lens), just nothing significant artistically.  But here it is.
