mind to share which shop are you going to get? Helping my friend to search for a unit but most of the store no stock.

Hell no. Writing speed too slow.

Amandaaaaa....u no good lor no jio us 2gether XD

If for action pics

1. Go for slightly higher shutter speed,
2. Bump up ISO
3. AF-C auto focusing mode, so that our D90 can keep hunting for the focus continuously for moving subject
4. If still too dark, increase flash power.

I personally feel that if you are using shutter priority, yes. You are taking control of the shutter speed, but if you're using a higher shutter speed, there's not much to compensate on the aperture
because the largest aperture for the kitlens that it can go is like f/3.5-5.6. So, try to use other variables to compensate the lighting as well such as ISO and flash output.

Since you got an external flash there, I think you should be good to go.

maybe u r too near to d food

45cm minimal focusing distance bro. And make sure you are focusing at the right place.

Unless you got a macro lens then you can go closer.

50mm f/1.8 and a +4 close up filter does wonders for food photography. Small, light, cheap, works well in dark restaurants and gives very nice shallow DOF.

Take off the filter and then can use to take your date's pic as well.

18-55 can focus quite close one right? But 35mm f2 and 17-35 f/2.8 is even closer if not mistaken
