Pls. turn the little knob near the finder untill you get clear picture inside finder, previous owmer might have turn the knob for his eye sight good luck.

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

it won't take the picture until the focus is not confirmed (big dot lights up in the lower right side of the viewfinder) even though the button is pressed all the way down.
tamron lenses are notorious for slow (noisy) auto focus, so you have to be patient when focusing and half press repeatedly several times before it locks down, confirmes the focus and takes the picture.

Because it's not supposed to. The LCD on the D40 is for menus, shooting info, and image review. It takes pictures the same way SLRs have done for half a century, allowing you to view and frame through the viewfinder. Only more recent dSLRs (and not all of them) have the Live View feature allowing you to use the LCD instead of the viewfinder.

i recently added a new memory card to my camera,i have selected auto in image storage under menu button my internal memory says full and i have deleted all memory and internal memory pic and it still says full internal memory and won`t let me take any pics,what can i do on this matter?

What type of batteries did you buy?

For digital cameras, you want to use batteries with high milliamp hour (mah) rating: "2500 mah" if they are rechargeable.

If you bought regular batteries, you want to use good quality. Look for the "e2" or "better for digital equipment" type.

Does the camera have a DC power plug option? Try taking pictures with it plugged in if it does. If it still malfunctions with power right from the wall, then you bought a bad camera.

ON digital slr cameras there is no pic framing on the LCD display.

when you use the full auto mode, the body take jpeg images in sRGB mode. And it create a different folder for those, but perhaps your computer is tune to get THIS folder. So when you leave the full auto mode, the 5D create a second folder for new images. Try to open directly the 5d volume on your computer (in windows, configuration panel, on a mac, it mount automatically on desktop) and go into DCIM folder. see? there is two folders, aleluia.
