the new pmw320 came out recently. its the shoulder mount version of the ex1 cam.
a friend of mine who bought is using his standard def lens on it and claims it looks great. he likes it better than the supplied hd lens that came with it.
my question will it look as good? will the true high quality hd image come out using that lens. if not what is it about the hd lens that makes a difference, whether it be slight or very drastic.
thanks

It really depends on the lens and the situation. Some SD lenses are very good, virtually indistinguishable from HD lenses. Some perform well but may become softer wide open or at extreme ends of the lens. Best thing to do is to test it for yourself. A decent SD lens will probably handle better than the stock lens and be better made, things like the servo zoom will be faster. If the 320 stock lens is the same design as the 350's, the focus lags by around 1 frame but this only really shows up on crash zooms if you frame by frame the footage.
