Default A few issues with indoor pics using my xsi

I bought this camera several years ago as our general family camera. We were not have any luck with our point and shoot. So i invested in this along with the 55-250 lens, 50mm lens, and a Metz 48 external flash.

I always use the flash for indoors pic with the kit lens. My pics still dont come out right. I have tried positioning the flash in different directions with no luck. The pic still dont come out right. I usually just point the flash at the ceiling. I have also tired various settings. Nothing seems to help. A friend of our has the t2i and swears by the auto setting. Her pics do always look good.

The example specifically i am talking about here is pics taking yesterday while the family was over for my sons first communion.

Is it time to upgrade to a t3i or t4i body?

You need to post one of the pictures here so we can help diagnose what the problem might be.

Netman - can you provide the exif data please?
One thing that is very troubling here is the right half of the image is noticeably sharper than the left half. The people, even the fireplace - as you start looking at the right end of the frame and move your eyes to the left the image becomes progressively less focused. That should have nothing whatsoever to do with the flash. Is this a common occurence for you? Does it happen with all lenses or just the lens you used here?

I always have issues with this lens indoors. I dont use the other lenses indoors. The 55-250 does work well inside. I dont have the room. I typically dont use my 50mm lens for anything.

If you're using flash, I'd think you could stop down some more. The increase in the depth of field should help with the softness. The XSi also has a flash sync speed of 1/200, so I'd use that instead of 1/60. The shutter speed doesn't affect the exposure since what matters is the duration of the flash, which is controlled automatically.

Agree that f4 probably isn't narrow enough.
However, there is still the issue of focus getting totally out-of-whack as you move from right to left when viewing. That isn't a DOF issue at all. That's a problem that needs diagnosing. So, Netman - does this problem exist with all photos? With all your lenses?

As far as shutter speed - it is still important because it affects how much of the ambient light is involved in the exposure. I'd be hesitant to jump to 1/200 - you might end up with a much starker contrast between the light in the background and the light on your subjects. BUT, it is true the shot looks overexposed - however, narrowing your aperture from f4 to f5.6 will help with that.

Right now, the biggest problem is whatever is happening to the focus on the left side of the frame - that issue has nothing to do with DOF and nothing to do with flash or exposure.

The focus problem did seem to happen on all of the photos i took on sunday. Before that I dont remember seeing that kind of issue.

I only have the 3 lenses. The kit lens that i use almost always. The 50mm i never use. the 55-250 I hardly use.

All these pics were taken in auto mode on the dial. I didnt change anything else on the camera. My understanding is of auto mode on the dial is that all settings will be set accordingly.

Some pic do come out better than others in the past but they are never great. That is why i was wondering if my xsi needed to be upgraded.
