Compare pictures from SX50, SX60, SX70 (my way)..

P mode can't be blamed here, but Auto ISO can. Guess that Auto ISO can be useful if in a hurry, but I have never used it. It'll often choose a higher ISO than necessary in the situation, resulting in more noisy images (and/or less detail because the camera will use more NR at higher ISOs).

Anyway, thanks for posting the comparison. Very interesting.

..albeit, the "Rate of Change" (as been mentioned previously) for both the SX50 & SX60 was set to "fast", and maybe if set to "standard" would be better..

..and to note that the SX70 does not have this "Rate of Change" setting (as been mentioned previously)..

..but this also shows the "behaviors" for each of the camera's workings..

..and I think it's very interesting to notice..

..happy shooting my friend,

..Cheers..

The one thing you can trust Auto ISO to do, is to raise the setting higher than you'd want, for the best quality. I always manually set the ISO to 100 in P mode and very sparingly raise it, when the light gets dim and never above 200 for photos, with a small-sensored superzoom camera. If ISO 200 won't do it, then it's time for a multi-exposure, low-light mode.

Video is an entirely different thing for ISO. In dimming evening light, ISO 400 is often necessary or even a bit higher in a few cases. Sometimes, Auto ISO is best for video in dim light, as if you pan across a changing level of light, a locked manual setting won't give a steady result. A wide or multi-point metering setting for video is often needed, as panning with spot or center metering will cause disruptive fluctuations in brightness. A white or yellow car going by, will also cause fluctuations in spot or center metering.
