I havenot used he latest electronic Noblex but I regularly use a last generation Noblex 150F. Yup it has batteries so carry spares. Beyond that it is built like a tank. One of the sturdier cameras I have used. I have been using this camera for 5 years and have not had any equipment failures with it (operator failures ... sure). I always carry a tripod and try not to handhold the camera but it can be done ... jus tremember that with a swing lens camera the real exposure time in terms of how long the lens is movingis much longer than the nominal speed you choose.
You do need to treat the camera with more care than a stanard camera but it is not delicate.
