Thank Andy....got to be honest (so new to this) I am not sure is a 50mm for everyday? Just worried it leaves me with no zoom function.

As above
Yes you still have a zoom function
It's called your feet
Seriously, taking a shot with a prime lens, can make all the difference, not just because of the improved quality, but it also makes you think a bit more about the shot.

Such a good lens for the price would rather this came with the camera then the kit
I have a Canon Eos 500d. 18 - 55mm IS kit lens and 55 - 250mm IS lens (both by Canon). So many posts on here say they all have a 50mm ("nifty fifity"). Just wondering if I should buy one? If so which one - what is the 50mm used for? Thanks
