Hi I would like to ask if anybody knows why my pictures will have all these brown spots?
Is there something wrong with my camera internal?
I changed a different lens but the spot remains.:(

Dust on the sensor of your D40x.

Do you have an air blower like Giotto's Rocket Blower? Try that first. Do NOT use canned air - it may damage your sensor.

There's also the option of using a carefully cleaned paint brush, and there's always wet cleaning using Eclipse. I've done all 3, and if you're careful they will clean your sensor without damage. Google or search the forum for "sensor cleaning".

Others use cotton buds, lens pen, and other more exotic methods. I've never tried them, and I wouldn't recommend them.

Congratulations, your first dust :)
See if there is more than one dust spot. Set aperture to f/22, manual focus to minimum distance and shoot something evenly bright (white wall, paper, bright sky). Then shift the cam and shoot again. Compare both pictures. Dust will appear in both pictures at the same position.

alternatively, you can send to Nikon for cleaning of sensor = $24sgd. Takes less than half hour.

I suggest you learn to do it yourself, or live with it. $24 is not expensive, but if you change your lens often, it's going to get dusty very often. I'm not sure how much a Giotto costs in Singapore, I bought mine for less than S$20. It won't get rid of all dust, but the ones that are visible at f/8 (like in your image) should be easily removed. Personally I find using a brush followed by air blowing works really well.

Here's DIY instructions on how to choose and clean a brush.
