The most likely cause of blurring in this instance and looking at your EXIF data, I believe would be camera shake. At 1/5s and a 62mm focal length there is likely some movement as you press your shutter. Even on a tripod at slower shutter speeds there is a risk.
Ideally use a remote release and if you can use the mirror lock up before releasing the shutter for the exposure.
As a guide any shutter speed below the focal length of the lens in use is highest risk for camera shake. For example using a 200mm focal length then any shutter speed under 1/200s will be higher risk of movement. At 50mm then 1/50s becomes your guide shutter speed before slight movement can be detected.
The higher resolving power of the latest sensors is also impacting on camera shake being picked up. Owners of the Nikon D800 reported issues with soft images that was linked to the higher IQ requiring more care at the taking stage to avoid the sensor resolving even the slightest movement.
I hope that helps. A tripod is not enough in many cases.
As to your image here. I find the framing a little tight and would want to have a little more space around the edges. The arrangement is pleasing enough however.
Lighting is a little flat and as a result the colour in the fruit is not punching enough.
I would suggest a tweak in levels as well as some subtle saturation modifications to try and lift this.
