my hand shaking non-stop also cant see whether it is sharp or not :S
You need to improve on your technique then. Handheld shots with MF lenses require a bit of discipline. Read up on ways to steady yourselves (grip, straps, breathing techniques). The breathing technique is a staple for shots; goes somewhat like, inhale, half shutter focus, exhale halfway, shoot.
Also remember to take into consideration the focal length / shutter speed adjustments (known as the Reciprocal rule). Your shutter speed should not be slower than your focal length. So for the NEX, it would be Shutter Speed = 1/Focal length*1.5. If you were shooting with a 50mm, that would be 1/75. 75 because focal length multiplied by 1.5 (crop factor of NEX sensor, and most APS-C sensors).
Of course, sometimes you are not allowed the luxury of shooting at faster shutter speeds. This is where the other techniques come in. I've shot with 90mms at 1/30 speed, sharp. Look for hard, steady surfaces to rest yourself on. Have a proper foot stance to ensure you have maximum stability. Keep your elbows as close as possible to your chest. A lot more.
