You mentioned these for recommendation?
Tamron 17-50 f/2.8Tamron 17-50 f/2.8 VCSigma 17-50 f/2.8 OSSigma 17-70 Macro OSI have not tried any of the above, but I have friends using both the Sigmas mentioned. I have not seen any photo from the Sigma 17-50, but I have seen the Sigma 17-70 which is quite soft. Somehow, I personally felt that Nikkor 18-105 kit can do better than that when equipped with flash.
I'm earning from photography but not very much at the moment as I'm still green. I'm opting to upgrade to a better lens as compared with the kit. I did in fact considering the 24-70, however to move for that I'll lose some on wide coverage which is very important especially in tight area. I wouldn't be able to fund myself to move into both 24-70 and FX at the same time, which therefore I'm considering the Nikkor 17-50 f/2.8 and to hang with it longer before FX a year later or so.
The best price I managed to seek for the Nikkor 17-50 f/2.8 M'sia unit is RM3,900.
There's one more which is Sigma 18-50mm f/2.8 EX DC Macro; It has macro capability up to 1:3 magnification.
As for review, the Tamron is sharper, especially the older one (e.g. non VC model).
I'm not sure about the softness comparison with kitlens, but the advantage is basically on the aperture side; unless you comparing at similar aperture. As for the 17-70, it's not constant aperture so, I wouldn't really look into it.
The reason I bring it up is simply because of the price NEW vs NEW.
Unless you're going for 2nd hand Nikkor 17-55mm f/2.8, which you need to becareful not to get a problem unit; This usually no more warranty and any problems, this is a nearly RM4K used glass..... and it's also very heavy and pretty huge.
Anyway, it's up to you; You can always try out all the lens first before making decisions; Many pros wedding photogs also use the Tamron/Sigma equivalent and still deliver excellent image quality; without people knowing what they use.

i got the UV filter on, could it affect the picture? i remember that i over NR and and around -10 clarity
ok about the iso, ill test again this wednesday(public holiday) at midvalley i try 1600 n above
the focus at the eye(single servo) and Af-area is single-point AF?
If you're using low quality filter, it'll affect more. The filter is not really necessary, you can google more about it and read about it yourself; As for the fro, he is against filter.
You can set your camera max ISO, minimum shutter speed and so on; It'll help you control on the settings.
If you're relying on the VR, after you focus, you need to wait a short while for the VR to stabilize the image.
If you're shooting with wide aperture OR close up, you need to becareful of movements and the DOF will be more shallow and movements will shift the focus plane, resulting in out of focus; At wider angle, you will have more DOF.
If you subject is standing still for you to shoot, you can stay on AF-S, single point; Careful when using focus-recompose method (e.g. focus using the center-point, lock the focus, then recompose the image), depending on how you shoot, the focus plane may shift resulting in out of focus; Usually happen for wide aperture and/or close up.
Try to make sure the focus is lock on accurately, sometimes it may not be spot on, it may focus wrongly if there is not enough contrast, etc. resulting in out of focus again. If quite hard to see it clearly through the viewfinder, need to get use to it.
