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

Actually ....Not Bad......Not bad at all for indoor lighting, and hand
held at FL=360mm (eq.)

Well, the camera's full name is SX120-IS, and the IS
may help ;-)

I was certainly (initially) astonished
by what my little Canon A590IS could do in this regard,
compared to my previous Canon A630.

The IS definitely helps. I'd be hard-pressed to get a similar shot with a
non-stabilized lens.

I also had my XSi and the 75 - 300 along for the ride, and took some shots
with it. There was noticeable shake in those pics at similar shutter
speeds.

But, I haven't been in a situation where I can shoot at that amount of zoom,
lately, so I'm a bit out of practice when it comes to steady grip shots.

I want to go back and do a few tripod shots, but I might have to try some
more handhelds in the 400+ (35mm equiv) range to see if I can get a useable
image.

Thanks for the feedback, BugBear

Take Care,
Dudley

Commenting only on the small image, because its about the same size as
a print, it's as good or better than would appear in my local newspaper.

No distortion or fringing noticeable. It's more than sharp enough for
its purpose. Some colour noise in places, but not too distracting and
could be reduced in an editor if necessary.

Great shot, Dudley.

Thanks, Pete, appreciate the feedback.

I'm surprised that little sensor isn't noisier than it is. Canon must be
improving it's noise reduction processing...

In the future, I'll have to sit a bit closer and try for more expressive
close-ups...

BTW, Mich loves the Council Chambre, as there's a lot of room between the
rows. Lots of room for him to spread out and catch some z's while I play
around with the cams...

Take Care,
Dudley

Barrel distortion can be trivially post corrected.

Is that barrel distorting, or a curved wall?

Distortion at full zoom is pincushion. Here it is offset by the curved
wall and is barely detectable towards the top left corner.

true

I didn't notice the pincushion, but thought bugbear might have been
confusing the curved wall with barrel distortion.
