since I've been on this forum.  Here are a couple of shots.  The first is "FiFi" from the Fort Worth Alliance Airshow last fall. The second is a friend of mine's Beechcraft Duke I photographed yesterday while trying out my new-to-me lens. The second one is a little softer than I would like.  I have yet to find the sweet spot for this lens.  It's a Canon EF 70-300mm f/4-5.6 IS USM.
