Is there something wrong with my second-hand s90? Bit blurry over range.

Hi everyone. I bought a Canon s90 about 6 months ago off eBay and have been really enjoying it. The quality of the image on macro shots is phenomenal but I when it comes to taking photos over longer distances I can't help but feel it looks a little blurry. I've looked at online galleries and to me it looks like there might be a problem. I've uploaded some photos below so you can see for yourself in the original .jpg format shot in Auto Mode and I always try and keep my hands as still as possible when shooting. I tried comparing RAW to JPEG and couldn't see any difference in image sharpness.

You'll have to download the image to see them properly since the preview that the site creates is rubbish.

Also just a quick question about the s95, is the quality of the photo over mid range any better than the s90?

Thanks!

It may just be camera shake on the tele mode. What is your IS setting set to?

I'm sorry I'm not very knowledgeable about cameras, what's an IS setting?

Oh and all of those photos were unzoomed.

On my S95, it's located in the shooting menu called IS Mode. It's also known as the "anti-shake" setting. I leave mine in Continuous mode. Have you tried taking a picture on a tripod? Use the timer setting and turn off the IS before taking a picture. Compare and see if you get the same results.

I can't open any of your link's
