Title: Canon EF 70-300mm f/4.5-5.6 DO IS USM

Pictures of Shuttle Endeavor on 9/21/2012 as it takes its victory lap over Los Angeles before final landing at LAX to begin grooming for a permanent place in the California Science Center.  These shots were taken as the shuttle flew over NASA's Jet Propulsion Lab near Pasadena. Exciting sight as it flew overhead at 1500 ft!  :)

Pictures taken with Canon 7D + Canon EF 70-300 f/4.5-5.6 DO IS USM.  Shuttle#1 is uncropped, taken at 300mm (480mm crop) at 1/400 sec, f/8, ISO 100.  Shuttle#2 is cropped, with same exposure, except shutter speed was 1/640 sec.   Both images shot in RAW using AI Servo and high-burst option.

I bought a used 70-300mm DO lens and used it for a few months.  I loved the compact size (same size as a 24-105L), the IQ was ok with a little extra TLC in post (boost contrast and sharpness a bit more than normal).  I didn't like the horrible zoom creep, and as I said, the IQ was ok - but not great.  I also didn't like the bokeh.  I eventually sold the lens (for the same amount I paid for it) - a free long-term rental as a try-out.  That was before the 70-300L came out - I'd definitely prefer the L to the DO lens.

Here are a couple of shots:
