A friend of 15+ years got married this weekend so I, of course, wanted to document this event as best I could for him. Thankfully, two other friend felt the same way.
There were two 10d's and an Elan 7 in attendence.
Lane had a 420ex
Terry had a 550ex
I was manually using a 285hv (due to money constraints).
Half way through the evening Terry let me use his 550ex and I cannot believe the difference it made, the photos just came alive!
So, I ordered a 550ex today.
On another note, Lane shot a few photos with my 10d using his 16-35ef 2.8 lens and there is little or no discerable difference between it and my Sigma 24-70 ex 2.8 in jpeg mode. Maybe if it was shot in RAW or magnafied to 600% I would see a difference.
