Powershot SX10 IS versus Powershot A400 point n shoot.......

by mmartell36 / September 18, 2009 9:12 AM PDT

Hi...i'm trying out the Canon Powershot SX10 IS (I got a great deal on it) and trying to compare it to my much beloved Canon Powershot A400. In my initial trials the photo quality of the SX10 (with 10 megapixels) seems softer than that of my A400 (with 3.3 megapixels). That being said, is it possible that the A400 can have better overall photo quality than the SX10 despite only having a lower resolution?

Canon SX10 and A400

There is no easy answer to your question.

The megapixels have more to do with printing than with viewing on a screen.

And you have to be sure that you are comparing apples and apples.

You have to be comparing the exact same scene.
You have to be using the exact same shutter speed, aperture, ISO setting and zoom setting

Both cameras have a very sharp lens.
The A400 has less Megapixels and less pixel density, which lets it put larger pixel elements on each CCD sensor.
That reduces the noise generated by an overcrowded CCD sensor assembly.

The A400 is limited to ISO 400 while the SX10 lets the camera select as far as ISO 1600.

Take a picture with the A400, then write down the shutter speed, aperture setting, ISO setting and zoom setting.

Take the SX10IS and use the Aperture Priority setting with the aperture set to the same setting, the ISO setting the same and zoom setting the same. The SX10IS will then select the correct shutter speed for a good exposure.
Now take the identical scene with the SX10IS.

Then you can compare apples to apples.

trying what was suggested..........what's going on here?

In reply to: Canon SX10 and A400

ok...i did as you suggested, but i found out that there was no real one to one correspondence with all of the variables you said to determine...i could get about to of the variables to line up but not the others, especially f-stop. So obviously there was very little similarity between the cameras.

Then I decided to compare the camera using their basic core functions like foliage, ISO, and exposure compensation. I gor mixed results though. in the daylight, outside....the SX10 was a clear winner with clarity, zoom, and color. But in macro mode the A400 was clearly superior in clarity. Zoom was not a variable and color was near identical. Clarity is was I look for in Macro mode.

So was is going on here?...

i think it might have to do with the camera trying to be a one size fits all kind of thing but only succeeding in only middle ground fields...i think it's possibly due to the lens being designed to try to cover all sorts of depths of field that it's rather stuck in the middle of success...but please I value anyone's answers on this suject

Thank you,

by mmartell36 / September 20, 2009 11:07 PM PDT

anyways....i just wanted add that the macro pics were shot under low to dim lighting conditions (inside at night sometimes with a small small flashlight on the subject..a micro machine starship)

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
