And the games I have got good shots at are contaminated with noise! Im really tired of noise
How close are you to the action (or allowed to be if you had to get nearer) ?
Samples : check the PF Lens databases as SpecialK already linked to above (much better than asking for samples in this thread).
Low light : - For your money the Sigma 30/1.4 is a superb lens and goes everywhere with me (great for low light, street shooting, portraits, tourist stuff and so on .... If you prefer a slightly longer FL then the FA 50/1.4 but that is a slight tele on APS-C.
Low light sports :- If you are close to the action then the FA 50/1.4 will work. If you are very close (court-side) then the Sigma 30/1.4 is an amazing lens and you can easily make big crops and still retain excellent detail/sharpness.
At a pinch the Tamron 90 could do this (and cover 3 of the 4 categories you are considering) but note the focusing is not as fast as some other lenses here (but it does have a focus limiter which helps a lot when using a macro lens for something other than macro). If you need a zoom then the Tamron 70-200/2.8 is a great lens but a little slow for dim basketball courts (for example). I still think you can choose a couple of older, faster and much cheaper MF lenses and prefocus on the area of the action you want to shoot as most AF still won't keep up with the action in low light unless you are court side or close to it or up your ISO to give you the faster shutter speeds you'll need. The 55-300 is to be avoided indoors - much too slow. The Tamron 28-75/2.8 could also be considered in this category too if you are close to the court .. it'll give you some interesting group / bench shots.
Macro :- Tamron 90 or add a Raynox 150 or 250 (depending on how close you want to get) to any lens you have now.
Portraits : Tamron 28-75/2.8 is the wedding togs lens so you can't go wrong. If you want to go the prime route then the Tamron 90 can double as a portrait lens (superb bokeh and it's f2.8 so not too shabby). Most people recommend the FA 50/1.4 which is an excellent lens for the money and the f1.4 adds better low light capability and much lower DoF.
Conclusion : Tamron 28-75/2.8 & a Raynox 150 or 250 will cover at least 3 of your categories.
