Finally I got a fixed 50 mm EF lens from Canon. It was quite cheap and I did a little job in my spear time, so I had the money to buy it. I myself would have never had the idea to buy such a lens, but after I had several conversations with my dear friend sabl1984, I decided to give the lens a chance.
I had no time to test it yet, but I'm already eager to do some nice b/w shots and some new sports pictures in b/w. Since there a lots of Karate events I'll watch in the next weeks I hope to catch some exciting moves!
