My first post here in ClubSnap... i'm very new to photography and i like to take pictures like moving subjects, and some landscape portrait and night landscape...anyone can suggest which lense should i buy...
Read up about the various lenses and their effects on perspective and field of view. There is no 'sports lens' or 'wedding lens' or whatever. There might be lenses more commonly used for certain occasions - but that does not mean other lenses are unsuitable or wrong. Use what brings the results that you want - depending on the conditions you find.
For the time bing use your kit lens and learn from there. Many people take great pictures of many different kinds with kit lenses, so it can't be the wrong lens, right?
sport is a very very diverse field. do you mean indoor matches, track and field, tennis, soccer? each of them are quite different and might have different requirements. if you just want a long lens, the tamron 70-300 VC is turning out to be quite the performer.
