Jellotranz, are these f/5.6 shots in a small dark club? I can tell from the reflections in the 3rd one it is day time. Being limited to f/5.6 makes for tough shooting in low light.:twocents:
By all means you do need to learn to make do with the gear you have, but if you are setting yourself up for a particular type of shooting you need to get the right gear. For me I bought a cheap 50mm f/1.8 and that gets me out of trouble in most situations.
