Nikon D40 is really a wonderful camera, any picture captured from this camera will increases my interest to capture more images.
The major reason is its perfect pixels which capture the images with full hd quality.
Its shutter speed is good , the battery backup is average and stay for 4 hours after full charge.
Due to average performer of its battery it is not so user friendly.
Overall I will say this camera is affordable with grate features.
Thanks.
