Hi raydio, thanks for the reply!
1. Take a photo in bright light.
Unfortunately it was pretty dark yesterday morning...
2. Instead of f/11, try an aperture of f/8 or just a little less but stay away from f/1.8.
I tried this over a range of aperatures f1.8/2.8/5.6/8/11/22 and the results at the focused areas are more or less the same
3. Use ISO 100, 200 or 400. Stay away from the "mid" ISO settings.
I guess I'll have to try again when I have the time but the only time I see the sun at home is on the weekends when I'm not working
4. Be sure that your IS is on or place the camera on a tripod. Tripod would be best.
I had used a tripod for the shot.
5. Try liveview focusing which is contrast based and very accurate.
Again I have to try this weekend.
6. Try your lens on another 60D... you can take it to the VIVO Canon shop and with permission, try your lens on their camera. Be sure to take your own SD card with you so that you can view the test photos at home.
Weekend >.<
7. Try another 50mm lens on your camera and compare the test photos with the photos you've already taken.
I have a friend with one and I'll most probably be meeting him this weekend too to try it out
Perhaps I'll upload some of the shots I've been taking and it might shed some light on why it's so gooey and soft

I sure do hope it's a problem with myself and not the camera
