Hello,
Done a fair bit of searching about the SJ4000 camera, there seems to be a lot of "copies" or fakes about.
Huge differences in prices for the same spec camera.
A couple of Sites show the differences between the real and the fakes.
Not sure I will take the chance of buying one !!.
There are other choices by well known Name companies, Nikon, Rollei, Vivitar, Polaroid and others.
Will have to do some more searching !.
John.
