A few weeks ago, when the 30D was announced, I posted that  I was
disappointed with the 30D. The reason for this disappointment was
that I was expecting a 10+MP camera. I own a 10D so was expecting an
increase from 6MP to 10MP...a worthwhile improvement to justify the
purchase of a new camera. And, at the time, I wasn't too interested
in the other features that the 30D had.

Well, I just back from a trip to South America last month having used
my 10D and I realised that I needed a camera with a very fast turn-on
time. I missed a lot of action-shots of glaciers collapsing. So, I
when I got back from my trip, I went ahead and bought the 30D.

The improvement in turn-on time, the improvement in writing speed,
high-speed shooting mode and implementation of spot-metering over my
10D was dramatic...I was very pleased with my 30D purchase. No
regrets. And of course I can now use the internal flash without my
lenses casting a shadow!

What to do with my 10D? It's still a very good camera and is more
than adequate for 90% of the types of photos that I take. It's got a
few scratches and dents but it works fine (even when soaked in the
rain for 6 hours!).
