Visited City Hall this morning and brought along the SX120 in order to
see
how it works at full zoom.

Took this pic from the back of the room, handheld at 1/100 sec (360mm).

I'm sure you will find a bit of camera shake, but I'm really interested
in
how the barrel distortion appears, ditto for purple fringing...

Appreciate anything you can tell me.

Take Care,
Dudley


Dudley, it is very sharp. A noticeable amount of noise that is acceptable.
And I cannot see any C.A. In the marble wall edges. If you are testing for
lens distortion, I would suggest shooting a flat object like a fence line
head on. And barrel distortion usually occurs when the zoom is set to
wide,
not telephoto. Overall, it appears that the camera does a nice job in your
hands.


Thanks, George, appreciate the feedback.

I thought there might be some straight lines in the wal behind the
councillors that might bring out the lens distortion-- didn't realize it was
marble. And, thanks for clarifying the terminology for me; I need to pay
more attention to the technical jargon...

It was a slow day for Council, so I got a bunch of pics of empty chairs in
addition to that one...

The next time I go back, I think I'll bring along a tripod and the XSi with
the 75-300. With all those faces, and all the drama, there could be some
interesting shots there.

BTW, while I was testing the cam, I was also testing a digital voice
recorder, the Sony ICDSX700. I was sitting at the back and there wasn't
anybody sitting near me. I was shocked when I played it back and could
understand the whispers of people sitting quite some distance away. That
little recorder could be a serious privacy threat...

Once again, thanks for the feedback, George.

TakeCare,
Dudley
