Hi Kazeem.. First welcome to EPZ I hope you enjoy the site.

Your image is lacking sharpness which appears to be down to camera shake. I am assuming that this is a hand held shot, if his is the case the speed you have selected is far to slow for the 300mm focal length you have used. As a rule of thumb you should be using a speed in excess of 1/300 ( 1/focal length) times the crop factor of your 500d which is 1.6 which in this case would be 1/480 sec to minimise the camera shake. Obviously your f stop and possibly ISO setting would need to be changed to achieve this.

Hope this helps.

Hi Kazeem, are you starting out in photography or are you experienced? Trev_B has told you where you went wrong, but if you are starting out, it will mean nothing to you what he has explained. Crop factor depends on the camera you have, yours, like many DSLR's are 1.6. The easy answer for correct shutter speed is the focal length you have your lens set at, ie, 100 - 200 - 300mm etc. Whatever your focal length you multiply it by 1.6. So as Trev said, you had your lens at 300mm, so multiply that by 1.6 = 480. Which equates to 1/480 of a second shutter speed. You need to work out roughly what you set your lens at and work out your shutter speeds and remember them. The next time you have your lens at 300mm, you know your shutter speed. Who said you needed to be a mathematician to be a photographer? Hope this helps if you did not understand Trev.
