My wife was lovely enough to buy me a Lowepro Slingshot 200 camera bag and the Canon 50mm F1.8 MK2 lens.

The first thing I did was to put a UV filter I had from an old lens onto it to potect the front element.

Then out of curiosity I took a shot with and without the filter:

1/200th Second, f5, ISO200 (partial crop from center of image at 300% shown below)

The results are really surprising, the image quality is much better on the right hand image where better definition and contrast can be seen.

Given that this lens is about £50 it seems silly to spend large amounts of cash on a UV filter - how much do I need to spend for a good quality UV filter that won't let the lens down too much ?
